Recent 50gh bitcoin miner

So I recently set up a 50 gh bitcoin miner. Not fast these days, but how much should this be making currently. Does 0.02 btc a day sound about right?

investing in two BFL 50 GH/s Bitcoin Miner

Hi miners..
I am fairly new to Bitcoin and mining process so basically I am a big newb with some money to invest.
I am thinking of buying 2 x 50 GH/s Bitcoin Miner from BFL since they say that they have them in stock to ship right away (I hope so). That would be a $5000 investment + 30% in importing fees for me so I was wondering what do you guys think? is it worth it? When could I expect ROI? By some predictions (which I'm very skeptical about) it should be in 3 to 4 months.

Solo Mining Bitcoin Node

I have a Gekko NewPac USB miner that I bought for fun while getting started. Overclocked, I average around 50 Gh/s.
The machine it’s connected to has a full Bitcoin Node on it. I’ve enabled the wallet, and would like to point my Gekko miner at the node via cgminer for solo mining, just as a lottery. I know the odds.
I’ve tried following several guides, but they are all fairly old. Is this still possible? And if so, can anybody help me with the bitcoin.conf file?

We are not even in a bull market yet. Usually these things happen when there is a lot of hype. ZigmaBit is scammer company with fake mining rigs to basically scam you. Their selling website is https://zigmabit.com/ , please don't even click the link. We do not want to give them any traffic, just watch the video down below.
They have listed 3 miners on their website:
  • ZigBit 2.0
  • ZigBit 3.0
  • ZigBit 5.0

https://preview.redd.it/406xtn2l3cb41.jpg?width=1676&format=pjpg&auto=webp&s=4933fa05a303be6ece49fa37c4e8845fa8636605
Which of course doesn't exist. They recommend that these miners will make some crazy gains, which of course will not happen. As these miners are fake. Seeing the specification makes me think these guys know very little about crypto currency mining. So for example the specification they are advertising on ZigBit 5.0 is :
  • Bitcoin-2000 TH/s
  • Litecoin-300 GH/s
  • Ethereum-75 GH/s
  • Dash-50 TH/s
  • Power Consumption-2400W
  • Power Socket 110V-240V
Now you understand what im talking about, seriously 2000 TH/s mining Bitcoin at 2400w (where the latest Antminer S17 is 72Th/s), or mining ETH and the profit is so big that it will cover the miner cost faster then month. And another thing, they using the same hardware to mine multiple currencies which every one of them needs different hardware. Worst thing is that people will loose money, and most likely some of them already did. People think they will get rich after buying this miner, which they will never receive. Their fake products look so bad, their cheapest version ZiBit 2.0 looks like an ATX power supply.

Few things to also note is :
  • They have support chat on their website. I did send them a message and got response after about 20 minutes. So they told me that they only accept crypto currency, and the products are shipped from United Kingdom. My last line of the chat was "im coming for you you'll be in jail soon ".
  • When you google miner name, there is few websites coming up describing how great is their product. This most likely is owned websites for this scammer or this is purchased content posts.
  • Last thing is that i tired to do checkout on one miner, there is btc address which has already received 7btc. Im not sure if this is some people got already scammed or this is fake volume, hope this is fake volume https://www.blockchain.com/btc/address/1C4RSshoK9veR4jCNStqF32QARS5oGnmzw . Hope none is scammed.
Sad to see that there is such kind of people who makes money on scamming others. Man karma is there , i believe it will come for you sooner or later.

Decred Journal – September 2018

Note: you can read this on GitHub (link), Medium (link) or old Reddit (link).

Development

Final version 1.3.0 of the core software was released bringing all the enhancements reported last month to the rest of the community. The groundwork for SPV (simplified payment verification) is complete, another reduction of fees is being deployed, and performance stepped up once again with a 50% reduction in startup time, 20% increased sync speed and more than 3x faster peer delivery of block headers (a key update for SPV). Decrediton's integrations of SPV and Politeia are open for testing by experienced users. Read the full release notes and get the downloads on GitHub. As always, don't forget to verify signatures.
dcrd: completed several steps towards multipeer downloads, improved introduction to the software in the main README, continued porting cleanups and refactoring from upstream btcd.
Currently in review are initial release of smart fee estimator and a change to UTXO set semantics. The latter is a large and important change that provides simpler handling, and resolves various issues with the previous approach. A lot of testing and careful review is needed so help is welcome.
Educational series for new Decred developers by @matheusd added two episodes: 02 Simnet Setup shows how to automate simnet management with tmux and 03 Miner Reward Invalidation explains block validity rules.
Finally, a pull request template with a list of checks was added to help guide the contributors to dcrd.
dcrwallet: bugfixes and RPC improvements to support desktop and mobile wallets.
Developers are welcome to comment on this idea to derive stakepool keys from the HD wallet seed. This would eliminate the need to backup and restore redeem scripts, thus greatly improving wallet UX. (missed in July issue)
Decrediton: bugfixes, refactoring to make the sync process more robust, new loading animations, design polishing.
Politeia: multiple improvements to the CLI client (security conscious users with more funds at risk might prefer CLI) and security hardening. A feature to deprecate or timeout proposals was identified as necessary for initial release and the work started. A privacy enhancement to not leak metadata of ticket holders was merged.
Android: update from @collins: "Second test release for dcrandroid is out. Major bugs have been fixed since last test. Latest code from SPV sync has been integrated. Once again, bug reports are welcome and issues can be opened on GitHub". Ask in #dev room for the APK to join testing.
A new security page was added that allows one to validate addresses and to sign/verify messages, similar to Decrediton's Security Center. Work on translations is beginning.
Overall the app is quite stable and accepting more testers. Next milestone is getting the test app on the app store.
iOS: the app started accepting testers last week. @macsleven: "the test version of Decred Wallet for iOS is available, we have a link for installing the app but the builds currently require your UDID. Contact either @macsleven or @raedah with your UDID if you would like to help test.".
Nearest goal is to make the app crash free.
Both mobile apps received new design themes.
dcrdata: v3.0 was released for mainnet! Highlights: charts, "merged debits" view, agendas page, Insight API support, side chain tracking, Go 1.11 support with module builds, numerous backend improvements. Full release notes here. This release featured 9 contributors and development lead @chappjc noted: "This collaboration with @raedahgroup on our own block explorer and web API for @decredproject has been super productive.".
Up next is supporting dynamic page widths site wide and deploying new visual blocks home page.
Trezor: proof of concept implementation for Trezor Model T firmware is in the works (previous work was for Model One).
Ticket splitting: updated to use Go modules and added simnet support, several fixes.
docs: beginner's guide overhaul, multiple fixes and cleanups.
decred.org: added 3rd party wallets, removed inactive PoW pools and removed web wallet.
@Richard-Red is building a curated list of Decred-related GitHub repositories.
Welcome to new people contributing for the first time: @klebe, @s_ben, @victorguedes, and PrimeDominus!
Dev activity stats for September: 219 active PRs, 197 commits, 28.7k added and 18.8k deleted lines spread across 6 repositories. Contributions came from 4-10 developers per repository. (chart)

Network

Hashrate: started and ended the month around 75 PH/s, hitting a low of 60.5 and a new high of 110 PH/s. BeePool is again the leader with their share varying between 23-54%, followed by F2Pool 13-30%, Coinmine 4-6% and Luxor 3-5%. As in previous months, there were multiple spikes of unidentified hashrate.
Staking: 30-day average ticket price is 98 DCR (+2.4). The price varied between 95.7 and 101.9 DCR. Locked DCR amount was 3.86-3.96 million DCR, or 45.7-46.5% of the supply.
Nodes: there are 201 public listening nodes and 325 normal nodes per dcred.eu. Version distribution: 5% are v1.4.0(pre) dev builds (+3%), 30% on v1.3.0 (+25%), 42% on v1.2.0 (-20%), 15% on v1.1.2 (-7%), 6% on v1.1.0. More than 76% of nodes run v1.2.0 and higher and therefore support client filters. Data as of Oct 1.

ASICs

Obelisk posted two updates on their mailing list. 70% of Batch 1 units are shipped, an extensive user guide is available, Obelisk Scanner application was released that allows one to automatically update firmware. First firmware update was released and bumped SC1 hashrate by 10-20%, added new pools and fixed multiple bugs. Next update will focus on DCR1. It is worth a special mention that the firmware source code is now open! Let us hope more manufacturers will follow this example.
A few details about Whatsminer surfaced this month. The manufacturer is MicroBT, also known as Bitwei and commonly misspelled as Bitewei. Pangolinminer is a reseller, and the model name is Whatsminer D1.
Bitmain has finally entered Decred ASIC space with their Antminer DR3. Hash rate is 7.8 TH/s while pulling 1410 W, at the price of $673. These specs mean it has the best GH/W and GH/USD of currently sold miners until the Whatsminer or others come out, although its GH/USD of 11.6 already competes with Whatsminer's 10.5. Discussed on Reddit and bitcointalk, unboxing video here.

Integrations

Meet our 17th voting service provider: decredvoting.com. It is operated by @david, has 2% fee and supports ticket splitting. Reddit thread is here.
For a historical note, the first VSP to support ticket splitting was decredbrasil.com:
@matheusd started tests on testnet several months ago. I contacted him so we could integrate with the pool in June this year. We set up the machine in July and bought the first split ticket on mainnet, using the decredbrasil pool, on July 19. It was voted on July 30. After this first vote on mainnet, we opened the tests to selected users (with more technical background) on the pool. In August we opened the tests to everyone, and would call people who want to join to the #ticket_splitting channel, or to our own Slack (in Portuguese, so mostly Brazilian users). We have 28 split tickets already voted, and 16 are live. So little more than 40 split tickets total were bought on decredbrasil pool. (@girino in #pos-voting)
KuCoin exchange listed DCBTC and DCETH pairs. To celebrate their anniversary they had a 99% trading fees discount on DCR pairs for 2 weeks.
Three more wallets integrated Decred in September:
ChangeNow announced Decred addition to their Android app that allows accountless swaps between 150+ assets.
Coinbase launched informational asset pages for top 50 coins by market cap, including Decred. First the pages started showing in the Coinbase app for a small group of testers, and later the web price dashboard went live.

Adoption

The birth of a Brazilian girl was registered on the Decred blockchain using OriginalMy, a blockchain proof of authenticity services provider. Read the full story in Portuguese and in English.

Marketing

Advertising report for September is ready. Next month the graphics for all the ads will be changing.
Marketing might seem quiet right now, but a ton is actually going on behind the scenes to put the right foundation in place for the future. Discovery data are being analyzed to generate a positioning strategy, as well as a messaging hierarchy that can guide how to talk about Decred. This will all be agreed upon via consensus of the community in the work channels, and materials will be distributed.
Next, work is being done to identify the right PR partner to help with media relations, media training, and coordination at events. While all of this is coming up to speed, we believe the website needs a refresher reflecting the soon to be agreed upon messaging, plus a more intuitive architecture to make it easier to navigate. (@Dustorf)

Events

Attended:
Upcoming:
We'll begin shortly reviewing conferences and events planned for the first half of 2019. Highlights are sure to include The North American Bitcoin Conference in Miami (Jan 16-18) and Consensus in NYC (May 14-16). If you have suggestions of events or conferences Decred should attend, please share them in #event_planning. In 2019, we would like to expand our presence in Europe, Asia, and South America, and we're looking for community members to help identify and staff those events. (@Dustorf)

Markets

In September DCR was trading in the range of USD 34-45 / BTC 0.0054-0.0063. On Sep 6, DCR revisited the bottom of USD 34 / BTC 0.0054 when BTC quickly dropped from USD 7,300 to 6,400. On Sep 14, a small price rise coincided with both the start of KuCoin trading and hashrate spike to 104 PH/s. Looking at coinmarketcap charts, the trading volume is a bit lower than in July and August.
As of Oct 4, Decred is #18 by the number of daily transactions with 3,200 tx, and #9 by the USD value of daily issuance with $230k. (source: onchainfx)
Interesting observation by @ImacallyouJawdy: while we sit at 2018 price lows the amount locked in tickets is testing 2018 high.

A critical vulnerability was discovered and fixed in Bitcoin Core. Few days later a full disclosure was posted revealing the severity of the bug. In a bitcointalk thread btcd was called 'amateur' despite not being vulnerable, and some Core developers voiced their concerns about multiple implementations. The Bitcoin Unlimited developer who found the bug shared his perspective in a blog post. Decred's vision so far is that more full node implementations is a strength, just like for any Internet protocol.

Frequently Asked Questions

NOTICE

This post is a temporary resting place for FAQs while we wait for the release of VertDocs.

What is Vertcoin?

Vertcoin is a digital peer to peer currency focused on decentralization and ASIC resistance. Vertcoin is aiming to be easily accessible to the everyday user without extensive technical knowledge. Vertcoin has started to lower the barrier of entry with lots of video guides and the development of the One Click Miner (OCM).

Why does ASIC Resistance Matter?

ASICs (Application Specific Integrated Circuits) are dedicated mining devices that can only mine one algorithm. Coins like Bitcoin and Litecoin both made GPU mining obsolete when SHA-256 and Scrypt ASICs were created.
ASIC Resistance and How it Makes Vertcoin Decentralized
Vertcoin believes that ASIC resistance goes hand in hand with decentralization.
ASICs are made by companies like Bitmain and almost all the original sellers of ASICs sell on a preorder basis. When pre ordering an ASIC you are buying from a limited batch that the ASIC company has produced. Often times the batch will not be fully filled and the ASIC company will often have left over ASICs. When the ASIC company has left over ASICs they will put them to work mining. Soon enough the ASIC company will have a very large amount of unsold ASICs that are mining and slowly the ASIC company starts to own a large part of the network’s hashrate. When an ASIC company(s) starts to own a large majority of the hashrate the network can become very centralized after a while.
Having your network consist of a few large companies can be very dangerous as they could eventually get 51% hashing power and 51% attack your network, destabilizing the network. When your network is made out of a lot of smaller miners, like Vertcoin, it is much harder for your network to be 51% attacked, therefore increasing network security. By having centralized hashing power your coin effectively centralizing the network as the centralized hashing power can deny transactions and stop any activity they don’t want.

What Ways is Vertcoin Superior to Litecoin and Bitcoin?

Network Difficulty Adjustments with Kimoto Gravity Well
Vertcoin uses a difficulty adjustment called Kimoto Gravity Well which adjusts the difficulty every block, whereas Bitcoin and Litecoin’s difficulty changes every 2016 blocks. By adjusting the difficulty every block Vertcoin’s block time can stay consistent by adjusting for the fluctuation in network hash rate from hash rate renting and part time miners. If a large miner switches off Bitcoin or Litecoin mining the network could be slowed to a crawl until 2016 blocks are mined and the difficulty can change to adjust for the new network hash rate. We observed this happen to Bitcoin when Bitcoin Cash became more profitable than Bitcoin and Bitcoin’s network hash rate saw a steep fall off, slowing the network to a crawl. If this was to happen with Vertcoin the difficulty would adjust after 1 block was mined, allowing Vertcoin to always be profitable to mine.
Anyone can Meaningfully help Verify Transactions
In Proof-of-Work crypto currencies miners help secure the blockchain and get rewarded with the block reward. In ASIC mineable coins like Bitcoin and Litecoin you can’t meaningfully verify transactions unless you pay 1000-2000$ for a ASIC miner. When you mine with a CPU or GPU in a ASIC mineable coin you make no meaningful impact on the network. It is like trying to break concrete with a shovel while everyone else has a jackhammer.
Simple Upgrades Aren’t Held back by 1-2 Large Miners
In ASIC market people buy ASICs in batches in a preorder. With Bitcoin ASICs there is not enough demand for ASICs so the batch often doesn’t get sold out so now the manufacturer has spare ASICs. Now that the manufacturer has spare ASICs they will often start mining with them and eventually the ASIC company has one of the highest hash rates. If the ASIC company doesn’t want a certain upgrade to go through, for example SegWit, they can vote with their hash rate to hold back the upgrade forever or at least until people who want SegWit get more hash rate.
You Have a Say in Protocol Rules and Consensus
In Bitcoin you are a passive observer because you can only issue transactions and you have no part in the process after that. In Vertcoin you can be apart of the process for deciding the ordering of transactions and deciding what transactions get into blocks.
Block Rewards and Transaction Fees are Distributed Evenly
In Bitcoin and Litecoin the block rewards and transaction fees are often given to the large miners in China due to mining centralization created by ASICs. Vertcoin distributes its mining rewards to people all around the world thanks to the mining decentralization.

When will Atomic Swaps Be Ready?

Atomic Swaps can be done in two flavors: On-chain and Off-chain (via Lightning Network). On-chain swaps were actually done already using Blocknet, you can see it in use on Youtube. We're looking into doing it again using Interledger.
However our main focus is to do off-chain Atomic Swaps using Lightning Network technology. Because it has the same benefits as Lightning transactions: No network fees and instant transactions.
For off-chain swaps we need Lightning Network to be fully operational. It's difficult to give an ETA on that since we aren't the ones developing it. U/gertjaap posted a video on the current state of the Lightning Network for Vertcoin a while ago, which you can see here.
This was actually the "bleeding edge" of Lightning Network at the time. was able to use it on VTC's main net, meaning that our blockchain is ready for the good stuff. As you can see however, it can't yet be considered production ready (most users would want a little better UX than a command line app).
Now off-chain Atomic Swaps is a technique based on the same principles as Lightning Network, but adds an extra complexity for it being across chains. So it's basically the same as a "multi hop" Lightning payment, which is not yet built by any of the implementations. They're still working hard on making the single-hop payments robust. So in order for AS to be possible, LN has to be fully operational.
A timeline cannot be given at this time, because frankly we don't know. The implementation of Lightning Network we feel has the most potential is LIT, because it supports multiple currencies in its protocol (where LND is bitcoin-only at the time and requires significant work to support other currencies, which is an essential part of being able to work across multiple blockchains).
LIT is open source and there's nothing secretive about its progress, you can see the development on Github. We even have our lead dev James Lovejoy (u/jamesl22) close to the action and contributing to it where possible (and our team as well through testing it on the Vertcoin chain).
So we're not developing LN or AS ourselves, we're just ready with our blockchain technology whenever it becomes available.
If we have any real progress that has some substance, you can expect us to let the world know. We're not interested in fluffy marketing - we post something when we achieve real progress. And we are not keeping that secret.

How do I Choose the Right Vertcoin Wallet?

Deciding what Vertcoin wallet you should choose can be a difficult process. You can choose between three different wallets: Core, Electrum and Paper. Once you decide you can use the "How to Setup Your Vertcoin Wallets" video guide to assist you.

Core

The Core wallet is the wallet that most people should use. It will store the entire blockchain (~2GB) on your computer. The Core wallet is the only wallet that fully supports P2Pool mining. You will also have to use the Core wallet if you plan to run a P2Pool node or any Vertcoin related server.

Electrum

The Electrum wallet is a light wallet for Vertcoin. You do not have to download the blockchain on your computer, but you will still have your own private keys on your computer. This is recommended for people who don't need to store Vertcoins for very long and just need a quick but secure place to store them.

Paper

The Paper wallet is as the name implies, a physical paper wallet. When generating a paper wallet you will get a pdf that will need to print out. A paper wallet is normally used for long term storage since it is the safest way to store Vertcoins. A paper wallet can also be called "cold storage." Cold storage references the storage of your coins offline, preventing you from getting hacked over the internet.

Ledger Nano S

The Ledger Nano S is a hardware wallet designed by Ledger. A hardware wallet is similar to a paper wallet since it is normally used for cold storage. The hardware wallet is on par with the security of a paper wallet while being easy to use and setup. Note: You should never mine directly to a Ledger hardware wallet.

How do I start mining Vertcoin?

We have many guides available for you to use depending on your computer specifications.

Where can I get the One Click Miner (OCM)

You can get the latest version of the One Click Miner in the Vertcoin Discord. The download is pinned to the top of the #oneclick channel.

What do all the Numbers Mean on P2Pool’s Web Interface

I've seen a lot of confusion from new miners on public p2pool nodes, so here's a primer for the most common static node page style, for first time miners: https://imgur.com/K48GmMw

Active Miners on this Node

Address - This is the list of addresses currently mining on this node. If your address does not show up here, you are not mining on this node.
Hashrate
This is a snapshot of your hashrate as seen by the node. It will fluctuate up to 15% from the hashrate you are seeing on your mining software, but will average out to match the output in your mining software.
Rejected Hashrate
This is the amount of your hashing contribution that is rejected, both in hashrate and as a percentage of your total contribution. Running your own p2pool node minimizes this number. Mining on a node that is geographically close to reduce lag also minimizes this number. Ideally you would like it to be less than 1%, but most people seem happy keeping it under 3%.
Share Difficulty
This speaks for itself, it is the difficulty of the share being currently worked on. Bigger numbers are more difficult.
Time to Share
This is how long you need to mine before you will receive any payouts, or any "predicted payout." The lower your hashrate, the higher your time to share.
Predicted Payout
This is the reward you would receive if a block was found by p2pool right now. If it reads "no shares yet" then you have not yet been mining the requisite amount of time as seen in the previous "time to share" column.

Status

Network Hashrate
This is the total hashrate of all the miners mining vertcoin everywhere, regardless of where or how.
Global Pool Hashrate
This is the total hashrate of all the miners mining vertcoin on this p2pool network, be it the first network or the second network.
Local Pool Hashrate
This is the total hashrate of all the miners mining Vertcoin on this node.
Current Block Value
This is the reward that will be given for mining the current block. The base mining reward is currently 50 VTC per block, so any small decimal over that amount is transaction fees being paid by people using the network.
Network Block Difficulty
This is the difficulty of the block being mined. The higher the number, the higher the difficulty. This number rises as the "Network Hashrate" rises, so that blocks will always be found every 2.5 minutes. Inversely, this number falls when the "Network Hashrate" lowers as well.
Expected Time to Block
This is a guess at how much time will elapse between blocks being found by this p2pool network. This guess is accurate on average, but very inaccurate in the short term. Since you only receive a payout when the network finds a block, you can think of this as "Estimated Time to Payout."

Why is P2Pool Recommended Over Traditional Pools?

Decentralisation

P2Pool is peer to peer allowing a decentralized pool mining system. There are many nodes setup around the world that connect to each other too mine together. Many other coins have 1 very large pool that many miners connect to and sometimes the largest pool can have 51% or more of the network hash rate which makes the network vulnerable to a 51% attack. If P2Pool is the largest network then that prevents the Vertcoin network to be susceptible to a 51% attack as P2Pool is decentralized.

PPLNS Payout System

P2Pool uses a PPLNS (Pay Per Last N Shares) payout system which awards miners more the longer they mine, sort of like a loyalty system. A drawback to this system is that part time miners that aren't 24/7 won't be able to earn that much.

2 Networks

While Network 1 is catered towards 24/7 miners and people who have dedicated mining rigs, Vertcoin has a second P2Pool network where part time miners and miners under 100 MH/s can go to mine.

Mines Directly to Your Wallet

P2Pool mines directly to your wallet and cuts out the middleman. This reduces the likely hood that the pool will run away with your coins.

No Downtime

Since P2Pool is decentralized and has different nodes for you to choose from there will be no downtime because the P2Pool network does not die if one node goes down. You can setup a backup server in your miner so that you will have no downtime when mining.

Anonymity and Security

When using P2Pool you use a wallet address making your real identity anonymous, you are simply known by a random 34 letter string. Along with using a wallet address instead of a username there is no password involved P2Pool preventing the possibility of cracking your pool account (If you were on a traditional pool,) and stealing all your coins.

How do I Find a Nearby P2Pool Node

You can find the public p2pool nodes the the P2Pool Node Scanners. If you want to find a network 1 node go here. If you want to find a network 2 node go here.

How do I setup a P2Pool Node?

Linux P2Pool Setup
Windows P2Pool Setup (Text)
Windows P2Pool Setup (Video) This guide setups a network 2 node. When downloading Python download the 32bit version, not the 64bit. Downloading the 64bit version causes problems with the twisted install.
How do I setup a change my node to network 1 or network 2?
In the P2Pool startup script when you type the --network flag add vertcoin1 for network 1 and vertcoin2 for network 2 right after.

How do I Buy Vertcoin?

You can see a video guide on Youtube, "How to Buy Vertcoin with Fiat Using Bittrex and Coinbase"

How can I get help with "X problem?"

The quickest way for you to get help is for you to join the Vertcoin Discord Group. We almost always have knowledgable Vertans, whether that be developers or experienced Vertans, online to help you with whatever problems you may have.

How can I donate to the Developers?

You can donate to the dev fund at https://vertcoin.org/donate/. You can select what you want your funds to go to by donating to the corresponding address. You can also see how much funding is required and how much we have donated.

Where can I see what exchanges Vertcoin is on?

You can see what exchanges Vertcoin is listed on at CoinMarketCap. You can see what exchanges Vertcoin has applied to be on at this google docs spreadsheet.

Where can I see Vertcoin's Roadmap?

The Vertcoin developers currently have a trello board where you can see the goals and what the status of said goal is. You can also vote on what you want the Vertcoin developers to focus on next.

What is the Status of the AMD Optimized Miner?

The AMD Optimized Miner internal beta is aiming to be ready by the end of September. The AMD Optimized Miner is currently being developed by @turekaj on the Vertcoin Discord. He currently does not have a Reddit account and Discord is the only way you can contact him.

What Does Halving Mean?

Halving means that the block reward for miners will be split in half. Halving happens around every 4 years for Vertcoin or 840,000 blocks. This means around December miners will only receive 25 VTC per block instead of the current 50 VTC per block.
If you would like to add another question to this list please comment it and I will get around to adding it ASAP.

DD on Crypto. Just kidding Allin AMD

Alright, I keep seeing you fucks talk about how "Bitcoin is going to make Nvidia/AMD go to the moon". I'm going to walk all you fucks through bitcoin, crypto currencies, and how they effect the GPU market.
What is Bitcoin?
Bitcoin is a decentralized ledger. That's pretty much it. A set number of bitcoin is generated per block, and each block is solved when a resulting hash is found for the corresponding proof of work. The difficulty is adjusted periodically based on a formula, meaning that as hash rate rises and falls, the number of bitcoins produced per day is roughly the same.
What does Bitcoin have to do with AMD and Nvidia?
Fucking nothing. Bitcoin is mined on proprietary hardware called Application-specific Integrated Circuits (ASICs). Neither AMD or Nvidia produce these.
Why does everyone keep talking about Bitcoin and AMD then?
Because they're fucking retarded and you're listening to retards. Bitcoin runs on the SHA-256 Hashing Function which people have custom hardware for. The Crypto driving GPU sales is ETHEREUM, NOT BITCOIN
What the fuck is Ethereum then?
Don't worry about it. It's for smug assholes who are too edgy for Bitcoin. All you need to know is it runs on a different Hashing function than Bitcoin, so if you weren't a retard you'd probably realize that the proprietary hardware I talked about earlier won't work with it. Currently Ethereum is being mined the same way Bitcoin was when it first started; on GPUs.
When are you going to tell me what to buy
Shut the fuck up, learn something or kill your self.
How many GPUs are being used to mine currently?
Currently the Ethereum Hash Rate is 73,000 GH/s. For upcoming earnings, we should instead look at the period from April to June. April 1st shows a network hash rate of 16,500 GH/s, and June 31st shows 59,200 GH/s, meaning the network hash rate increased by 42,700 GH/s for this upcoming earnings report quarter.
I've linked a decent benchmark for GPU hashrate . You should notice that all of these are quoted in MH/s, versus the Network reporting in GH/s; there are ALOT of fucking GPUs running on the network. A top of the line 1080 puts out about 20-25 MH/s, a good Radeon card does about 30. As a rough estimate, lets assume that the average card mining Ethereum currently produces about 25 MH/s. 42,700GH/s / 25MH/s means that there are 1.7 MILLION more GPUs currently mining ethereum than there were at the beginning of Q1. Based on my personal observations being involved in this, AMD is actually taking a majority market share of the sold cards just due to their superior performance compared to Nvidia's 1080s, and I'd estimate that About 50-60% of the cards currently mining Ethereum are AMD Radeons.
What does this all mean?
AMD are selling their highest margin video cards faster than they can produce them, and at ~250$ a pop with 50%-60% market capture AMD will have sold roughly 200-300 million dollars more in video cards than they did last quarter. AMD quarterly revenue last reported was just under 1 Billion. This is a 20-30% increase in revenue from last quarter, where Ethereum Hash Rate only increased by about 10,000GH/s. Even assuming a modest 30% margin for their video cards, AMD will still have almost 60 million in unexpected earnings this quarter due to crypto mining, which translates to about .06-.1 per share in earnings.
tl;dr
Ethereum will make AMD beat revenue by 20-30%. BUY AMD YOU CUCKS.

2 Reasons Why Dogecoin Should Adapt Vertcoin's Features

Dogecoin should adapt both Scrypt-n as it's proof of work, and Kimotos Gravity Well as the method for adjusting difficulty.
Let me start with Kimitos Gravity Well. This is an algorithm used for adjusting the network difficulty. It adjusts the difficulty slightly every block rather than every set period, so that profit switching pools can not take advantage of it. It smooths out difficulty adjustments too.
This is needed because Dogecoin is about to be exploited by profit switching pools. Right now there's about 50 GH/s(over half of the network!) of profit switching pools mining Doge. When the block reward is halved in less than a week, we're going to see a ton of coin hopping between Litecoin and Dogecoin by these pools. This threatens the network, as the hashrate distribution and difficulty would become incredibly unstable. With this change, the difficulty would only fluctuate by about 5-10% throughout the day even with profit switching pools, unlike the 50%+ it will likely see using the current method.
The second thing is adaptive scrypt-n. Scrypt-n is a proof of work algorithm that makes ASICs nearly impossible to create. It adjusts the memory requirement on a block schedule, so that ASICs would likely never be made for it. ASICs are dedicated devices for mining that are much more power efficient than GPUs, and eventually will become more cost efficient. Dogecoin uses plain scrypt, and ASICs for it are already being developed. Eventually once these devices become more advanced, they will make gpu mining near impossible, and you will need an ASIC to profit or even make a moderate amount of Doge.
ASICs will make acquiring Dogecoin hard for newcomers. Looking at Bitcoin, many ASIC companies like BFL end up as scams, and those that aren't charge ridiculous prices for units that won't even make ROI. Mining with a gpu will get you nothing. I don't want this to happen to Dogecoin, as it is a fun cryptocurrency that is designed for the people. Eventually ASIC companies may withhold their technologies and use it for themselves, and as a result could control too much of the network. Look at Bitcoin, where KNC miner plans to create a 10 Megawatt mining farm in Sweden that is estimated to control 60-70% of the network.
Not just do ASICs ruin the fun of the coin by making it impossible for newcomers to easily mine a few doge, but it also ruins the security of the coin long term. I really hope we can convince the devs to implement scrypt-n, as I want Dogecoin to stay fun and secure. It sadly would require a hard fork, but it would be planned ahead of time. Better now than before Dogecoin grows larger, and before people with thousands of dollars invested into ASICs refuse to switch. Don't wait until ASICs become overpowered-it will be too late.
Vertcoin is a great coin from a technical standpoint, but it lacks the large and friendly community Dogecoin has behind it and also is deflationary, making it not as ideal as an internet currency that is intended to be shared a lot. I feel like Dogecoin could make great use of it's technology.

Decred's own DNS seeder (dcrseeder) was released. It is written in Go and it properly supports service bit filtering, which will allow SPV nodes to find full nodes that support compact filters.
Ticket splitting service by @matheusd entered beta and demonstrated an 11-way split on mainnet. Help with testing is much appreciated, please join #ticket_splitting to participate in splits, but check this doc to learn about the risks. Reddit discussion here.
Trezor support is expected to land in their next firmware update.
Decred is now supported by Riemann, a toolbox from James Prestwich to construct transactions for many UTXO-based chains from human-readable strings.
Atomic swap with Ethereum on testnet was demonstrated at Blockspot Conference LATAM.
Two new faces were added to contributors page.
Dev activity stats for May: 238 active PRs, 195 master commits, 32,831 added and 22,280 deleted lines spread across 8 repositories. Contributions came from 4-10 developers per repository. (chart)

Network

Hashrate: rapid growth from ~4,000 TH/s at the beginning of the month to ~15,000 at the end with new all time high of 17,949. Interesting dynamic in hashrate distribution across mining pools: coinmine.pl share went down from 55% to 25% while F2Pool up from 2% to 44%. [Note: as of June 6, the hashrate continues to rise and has already passed 22,000 TH/s]
Staking: 30-day average ticket price is 91.3 DCR (+0.8), stake participation is 46.9% (+0.8%) with 3.68 million DCR locked (+0.15). Min price was 85.56. On May 11 ticket price surged to 96.99, staying elevated for longer than usual after such a pump. Locked DCR peaked at 47.17%. jet_user on reddit suggested that the DCR for these tickets likely came from a miner with significant hashrate.
Nodes: there are 226 public listening and 405 normal nodes per dcred.eu. Version distribution: 45% on v1.2.0 (up from 24% last month), 39% on v1.1.2, 15% on v1.1.0 and 1% running outdaded versions.

ASICs

Obelisk team posted an update. Current hashrate estimate of DCR1 is 1200 GH/s at 500 W and may still change. The chips came back at 40% the speed of the simulated results, it is still unknown why. Batch 1 units may get delayed 1-2 weeks past June 30. See discussions on decred and on siacoin.
@SiaBillionaire estimated that 7940 DCR1 units were sold in Batches 1-5, while Lynmar13 shared his projections of DCR1 profitability (reddit).
A new Chinese miner for pre-order was noticed by our Telegram group. Woodpecker WB2 specs 1.5 TH/s at 1200 W, costs 15,000 CNY (~2,340 USD) and the initial 150 units are expected to ship on Aug 15. (pow8.comtranslated)
Another new miner is iBelink DSM6T: 6 TH/s at 2100 W costing $6,300 (ibelink.co). Shipping starts from June 5. Some concerns and links were posted in these two threads.

Integrations

A new mining pool is available now: altpool.net. It uses PPLNS model and takes 1% fee.
Another infrastructure addition is tokensmart.io, a newly audited stake pool with 0.8% fee. There are a total of 14 stake pools now.
Exchange integrations:
OpenBazaar released an update that allows one to trade cryptocurrencies, including DCR.
@i2Rav from i2trading is now offering two sided OTC market liquidity on DCUSD in #trading channel.
Paytomat, payments solution for point of sale and e-commerce, integrated Decred. (missed in April issue)

Adoption

New merchants:
An update from VotoLegal:
michae2xl: Voto Legal: CEO Thiago Rondon of Appcívico, has already been contacted by 800 politicians and negotiations have started with four pre-candidates for the presidency (slack, source tweet)
Blockfolio rolled out Signal Beta with Decred in the list. Users who own or watch a coin will automatically receive updates pushed by project teams. Nice to see this Journal made it to the screenshot!
Placeholder Ventures announced that Decred is their first public investment. Their Investment Thesis is a clear and well researched overview of Decred. Among other great points it noted the less obvious benefit of not doing an ICO:
By choosing not to pre-sell coins to speculators, the financial rewards from Decred’s growth most favor those who work for the network.
Alex Evans, a cryptoeconomics researcher who recently joined Placeholder, posted his 13-page Decred Network Analysis.

Marketing

@Dustorf published March–April survey results (pdf). It analyzes 166 responses and has lots of interesting data. Just an example:

Community Discussions

Community stats: Twitter 39,118 (+742), Reddit 8,167 (+277), Slack 5,658 (+160). Difference is between May 5 and May 31.
Reddit highlights: transparent up/down voting on Politeia, combining LN and atomic swaps, minimum viable superorganism, the controversial debate on Decred contractor model (people wondered about true motives behind the thread), tx size and fees discussion, hard moderation case, impact of ASICs on price, another "Why Decred?" thread with another excellent pitch by solar, fee analysis showing how ticket price algorithm change was controversial with ~100x cut in miner profits, impact of ticket splitting on ticket price, recommendations on promoting Decred, security against double spends and custom voting policies.
@R3VoLuT1OneR posted a preview of a proposal from his company for Decred to offer scholarships for students.
dcrtrader gained a couple of new moderators, weekly automatic threads were reconfigured to monthly and empty threads were removed. Currently most trading talk happens on #trading and some leaks to decred. A separate trading sub offers some advantages: unlimited trading talk, broad range of allowed topics, free speech and transparent moderation, in addition to standard reddit threaded discussion, permanent history and search.
Forum: potential social attacks on Decred.
Slack: the #governance channel created last month has seen many intelligent conversations on topics including: finite attention of decision makers, why stakeholders can make good decisions (opposed to a common narrative than only developers are capable of making good decisions), proposal funding and contractor pre-qualification, Cardano and Dash treasuries, quadratic voting, equality of outcome vs equality of opportunity, and much more.
One particularly important issue being discussed is the growing number of posts arguing that on-chain governance and coin voting is bad. Just a few examples from Twitter: Decred is solving an imagined problem (decent response by @jm_buirski), we convince ourselves that we need governance and ticket price algo vote was not controversial, on-chain governance hurts node operators and it is too early for it, it robs node operators of their role, crypto risks being captured by the wealthy, it is a huge threat to the whole public blockchain space, coin holders should not own the blockchain.
Some responses were posted here and here on Twitter, as well as this article by Noah Pierau.

Markets

The month of May has seen Decred earn some much deserved attention in the markets. DCR started the month around 0.009 BTC and finished around 0.0125 with interim high of 0.0165 on Bittrex. In USD terms it started around $81 and finished around $92, temporarily rising to $118. During a period in which most altcoins suffered, Decred has performed well; rising from rank #45 to #30 on Coinmarketcap.
The addition of a much awaited KRW pair on Upbit saw the price briefly double on some exchanges. This pair opens up direct DCR to fiat trading in one of the largest cryptocurrency markets in the world.
An update from @i2Rav:
We have begun trading DCR in large volume daily. The interest around DCR has really started to grow in terms of OTC quote requests. More and more customers are asking about trading it.
Like in previous month, Decred scores high by "% down from ATH" indicator being #2 on onchainfx as of June 6.

Relevant External

David Vorick (@taek) published lots of insights into the world of ASIC manufacturing (reddit). Bitmain replied.
Bitmain released an ASIC for Equihash (archived), an algorithm thought to be somewhat ASIC-resistant 2 years ago.
Three pure PoW coins were attacked this month, one attempting to be ASIC resistant. This shows the importance of Decred's PoS layer that exerts control over miners and allows Decred to welcome ASIC miners for more PoW security without sacrificing sovereignty to them.
Upbit was raided over suspected fraud and put under investigation. Following news reported no illicit activity was found and suggested and raid was premature and damaged trust in local exchanges.
Circle, the new owner of Poloniex, announced a USD-backed stablecoin and Bitmain partnership. The plan is to make USDC available as a primary market on Poloniex. More details in the FAQ.
Poloniex announced lower trading fees.
Bittrex plans to offer USD trading pairs.
@sumiflow made good progress on correcting Decred market cap on several sites:
speaking of market cap, I got it corrected on coingecko, cryptocompare, and worldcoinindex onchainfx, livecoinwatch, and cryptoindex.co said they would update it about a month ago but haven't yet I messaged coinlib.io today but haven't got a response yet coinmarketcap refused to correct it until they can verify certain funds have moved from dev wallets which is most likely forever unknowable (slack)

So you’ve got your miner working, busy hashing away … but what is it really doing?

Posted for eternity @ https://vertcoin.easymine.online/articles/mining
Your miner is repeatedly hashing (see below for detail about a hash) a block of data, looking for a resulting output that is lower than a predetermined target. Each time this calculation is performed, one of the fields in the input data is changed, and this results in a different output. The output is not able to be determined until the work is completed – otherwise why would we bother doing the work in the first place?
Each hash takes a block header (see more below, but basically this is a 80-byte block of data). It runs this through the hashing function, and what comes out is a 32-byte output. For each, we usually represent that output in hexadecimal format, so it looks something like:
5da4bcb997a90bec188542365365d8b913af3f1eb7deaf55038cfcd04f0b11a0 
(that’s 64 hexadecimal characters – each character represents 4-bits. 64 x 4 bits = 256bit = 32 bytes)
The maximum value for our hash is:
FFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFF 
And the lowest is:
0000000000000000000000000000000000000000000000000000000000000000 
The goal in Proof-of-Work systems is to look for a hash that is lower than a specific target, i.e. starts with a specific number of leading zeros. This target is what determines the difficulty.
As the output of the hash is indeterminate, we look to statistics and probability to estimate how much work (i.e. attempts at hashing) we need to complete to find a hash that is lower than a specific target. So, we can therefore assume that to find a hash that starts with a leading zero will take, on average, 16 hashes. To find one that will start with two leading zeros (00), we’re looking at 256 hashes. Four leading zeros (0000) will take 65,536 hashes. Eight leading zeros (00000000) takes 4,294,967,296 hashes. So on and so on, until we realize that it will take 2 ^ 256 (a number too big for me to show here) attempts at hitting our minimum hash value.
Remember – this number of hashes is just an estimate. Think of it like rolling a dice. A 16-sided dice. And then rolling it 64 times in a row. And hoping to strike a specific number of leading zeros. Sometimes it will take far less than the estimate, sometimes it will take far more. Over a long enough time period though (with our dice it may take many billions of years), the averages hold true.
Difficulty is a measure used in cryptocurrencies to simply show how much work is needed to find a specific block. A block of difficulty 1 must have a hash smaller than:
00000000FFFF0000000000000000000000000000000000000000000000000000 
A block of difficulty 1/256 (0.00390625) must have a hash lower than:
000000FFFF000000000000000000000000000000000000000000000000000000 
And a block of difficulty 256 must have a hash lower than:
0000000000FFFF00000000000000000000000000000000000000000000000000 
So the higher the difficulty, the lower the hash must be; therefore more work must be completed to find the block.
Take a recent Vertcoin block – block # 852545, difficulty 41878.60056944499. This required a hash lower than:
000000000001909c000000000000000000000000000000000000000000000000 
The achieve finding this, a single miner would need to have completed, on average 179,867,219,848,013 hashes (calculated by taking the number of hashes needed for a difficulty 1 block - 4,294,967,296 or 2 ^ 32 or 16 ^ 8 – and multiplied by the difficulty). Of course, our single miner may have found this sooner – or later – than predicted.
Cryptocurrencies alter the required difficulty on a regular basis (some like Vertcoin do it after every block, others like Bitcoin or Litecoin do it every 2016 blocks), to ensure the correct number of blocks are found per day. As the hash rate of miners increases, so does the difficulty to ensure this average time between blocks remains the same. Likewise, as hash rate decreases, the difficulty decreases.
With difficulties as high as the above example, solo-mining (mining by yourself, not in a pool) becomes a very difficult task. Assume our miner can produce 100 MH/s. Plugging in this into the numbers above, we can see it’s going to take him (on average) 1,798,673 seconds of hashing to find a hash lower than the target – that’s just short of 21 days. But, if his luck is down, it could easily take twice that long. Or, if he’s lucky, half that time.
So, assuming he hit’s the average, for his 21 days mining he has earned 25 VTC.
Lets take another look at the same miner, but this time he’s going to join a pool, where he is working with a stack of other miners looking for that elusive hash. Assume the pool he has joined does 50 GH/s – in that case he has 0.1 / 50 or 0.2% of the pool’s hash rate. So for any blocks the pool finds he should earn 0.2% of 25 VTC = 0.05 VTC. At 50 GH/s, the pool should expect to spend 3,597 seconds between finding blocks (2 ^ 32 * difficulty / hashrate). So about every hour, our miner can expect to earn 0.05 VTC. This works out to be about 1.2 VTC per day, and when we extrapolate over the estimated 21 days of solo mining above, we’re back to 25 VTC.
The beauty of pooled-mining over solo-mining is that the time between blocks, whilst they can vary, should be closer to the predicted / estimated times over a shorter time period. The same applies when comparing pools – pools with a smaller hash rate will experience a greater variance in time between blocks than a pool with a greater hash rate. But in the end, looking back over a longer period of time, earnings will be the same.
Hashes
A Hash is a cryptographic function that can take an arbitrary sized block of data and maps it to a fixed sized output. It is a one-way function – only knowing the input data can one calculate the output; the reverse action is impossible. Also, small changes to the input data usually result in significant changes to the output value.
For example, take the following string:
“the quick brown fox jumps over the lazy dog” 
If we perform a SHA256 hash of this, it results in:
05c6e08f1d9fdafa03147fcb8f82f124c76d2f70e3d989dc8aadb5e7d7450bec 
If we change a single character in the input string (in this case we will replace the ‘o’ in ‘over’ to a zero), the resulting hash becomes:
de492f861d6bb8438f65b2beb2e98ae96a8519f19c24042b171d02ff4dfecc82 
Blocks
A block is made up of a header, and at least one transaction. The first transaction in the block is called the Coinbase transaction – it is the transactions that creates new coins, and it specifies the addresses that those coins go to. The Coinbase transaction is always the first transaction in a block, and there can only be one. All other transactions included in a block are transactions that send coins from one wallet address to another.
The block header is an 80-byte block of data that is made up of the following information in this order:
  • Version – a 32-bit/4-byte integer
  • Previous Block’s SHA256d Hash – 32 bytes
  • Merkle Hash of the Transactions – 32 bytes
  • Timestamp - a 32-bit/4-byte integer the represents the time of the block in seconds past 1st January 1970 00:00 UTC
  • nBits - a 32-bit/4-byte integer that represents the maximum value of the hash of the block
  • Nonce - a 32-bit/4-byte integer
The Version of a block remains relatively static through a coin’s lifetime – most blocks will have the same version. Typically only used to introduce new features or enforce new rules – for instance Segwit adoption is enforced by encoding information into the Version field.
The Previous Blocks’ Hash is simple a doubled SHA256 hash of the last valid blocks header.
The Merkle Hash is a hash generated by chaining all of the transactions together in a hash tree – thus ensuring that once a transaction is included in a block, it cannot be changed. It becomes a permanent record in the blockchain.
Timestamp loosely represents the time the block was generated – it does not have to be exact, anywhere within an hour each way of the real time will be accepted.
nBits – this is the maximum hash that this block must have in order to be considered valid. Bitcoin encodes the maximum hash into a 4-byte value as this is more efficient and provides sufficient accuracy.
Nonce – a simple 4-byte integer value that is incremented by a miner in order to find a resulting hash that is lower than that specified by nBits.

IRC Log from Ravencoin Open Developer Meeting - Aug 24, 2018

[14:05] <@wolfsokta> Hello Everybody, sorry we're a bit late getting started

[14:06] <@wolfsokta> Here are the topics we would like to cover today • 2.0.4 Need to upgrade - What we have done to communicate to the community • Unique Assets • iOS Wallet • General Q&A
[14:06] == Chatturga changed the topic of #ravencoin-dev to: 2.0.4 Need to upgrade - What we have done to communicate to the community • Unique Assets • iOS Wallet • General Q&A
[14:06] <@wolfsokta> Daben, could you mention what we have done to communicate the need for the 2.0.4 upgrade?
[14:07] == hwhwhsushwban [[email protected]/web/freenode/ip.172.58.37.35] has joined #ravencoin-dev
[14:07] <@wolfsokta> Others here are free to chime in where they saw the message first.

[14:08] Whats up bois
[14:08] hi everyone
[14:08] hi hi
[14:08] <@wolfsokta> Discussing the 2.0.4 update and the need to upgrade.
[14:08] <@Chatturga> Sure. As most of you are aware, the community has been expressing concerns with the difficulty oscillations, and were asking that something be done to the difficulty retargeting. Many people submitted suggestions, and the devs decided to implement DGW.
[14:09] <@Tron> I wrote up a short description of why we're moving to a new difficulty adjustment. https://medium.com/@tronblack/ravencoin-dark-gravity-wave-1da0a71657f7
[14:09] <@Chatturga> I have made posts on discord, telegram, bitcointalk, reddit, and ravencointalk.org from testnet stages through current.
[14:10] <@Chatturga> If there are any other channels that can reach a large number of community members, I would love to have more.
[14:10] <@wolfsokta> Thanks Tron, that hasn't been shared to the community at large yet, but folks feel free to share it.
[14:10] When was this decision made and by whom and how?
[14:10] <@Chatturga> I have also communicated with the pool operators and exchanges about the update. Of all of the current pools, only 2 have not yet updated versions.
[14:11] <@wolfsokta> The decision was made by the developers through ongoing requests for weeks made by the community.
[14:12] <@wolfsokta> Evidence was provided by the community of the damages that could be caused to projects when the wild swings continue.
[14:12] So was there a meeting or vote? How can people get invited
[14:12] <@Tron> It was also informed by my conversations with some miners that recommended that we make the change before the coin died. They witnessed similar oscillations from which other coins never recovered.
[14:13] only two pools left to upgrade is good, what about the exchanges? Any word on how many of those have/have not upgraded?
[14:13] <@wolfsokta> We talked about here in our last meeting Bruce_. All attendees were asked if they had any questions or concerns.

[14:13] sup roshii long time no see
[14:14] <@Chatturga> Bittrex, Cryptopia, and IDCM have all either updated or have announced their intent to update.

[14:15] sup russki
[14:15] what's the status here?
[14:15] I don’t think that was at all clear from the last dev meeting
[14:15] I can’t be the only person who didn’t understand it
[14:15] <@wolfsokta> Are there any suggestions on how to communicate the need to upgrade even further? I am concerned that others might also not understand.
[14:17] I’m not sold on the benefit and don’t understand the need for a hard fork — I think it’s a bad precedent to simply go rally exchanges to support a hard fork with little to no discussion
[14:17] so just to note, the exchanges not listed as being upgraded or have announced their intention to upgrade include: qbtc, upbit, and cryptobridge (all with over $40k usd volume past 24 hours according to coinmarketcap)
[14:18] <@wolfsokta> I don't agree that there was little or no discussion at all.
[14:19] <@wolfsokta> Looking back at our meeting notes from two weeks ago "fork" was specifically asked about by BrianMCT.
[14:19] If individual devs have the power to simple decide to do something as drastic as a hard fork and can get exchanges and miners to do it that’s got a lot of issues with centralization
[14:19] <@wolfsokta> It had been implemented on testnet by then and discussed in the community for several weeks before that.
[14:19] == under [[email protected]/web/freenode/ip.72.200.168.56] has joined #ravencoin-dev
[14:19] howdy
[14:19] Everything I’ve seen has been related to the asset layer
[14:19] I have to agree with Bruce_, though I wasn't able to join the last meeting here. That said I support the fork
[14:20] Which devs made this decision to do a fork and how was it communicated?
[14:20] well mostly the community made the decision
[14:20] Consensus on a change is the heart of bitcoin development and I believe the devs have done a great job building that consensus
[14:20] a lot of miners were in uproar about the situation
[14:20] <@wolfsokta> All of the devs were supporting the changes. It wasn't done in isolation at all.
[14:21] This topic has been a huge discussion point within the RVN mining community for quite some time
[14:21] the community and miners have been having issues with the way diff is adjusted for quite some time now
[14:21] Sure I’m well aware of that -
[14:21] Not sold on the benefits of having difficulty crippled by rented hashpower?
[14:21] The community saw a problem. The devs got together and talked about a solution and implemented a solution
[14:21] I’m active in the community
[14:22] So well aware of the discussions on DGW etc
[14:22] Hard fork as a solution to a problem community had with rented hashpower (nicehash!!) sounds like the perfect decentralized scenario!
[14:23] hard forks are very dangerous
[14:23] mining parties in difficulty drops are too
[14:23] <@wolfsokta> Agreed, we want to keep them to an absolute minimum.
[14:23] But miners motivation it’s the main vote
[14:24] What would it take to convince you that constantly going from 4 Th/s to 500 Gh/s every week is worse for the long term health of the coin than the risk of a hard fork to fix it?
[14:24] == Tron [[email protected]/web/freenode/ip.173.241.144.77] has quit [Ping timeout: 252 seconds]
[14:24] This hardfork does include the asset layer right? if so why is it being delayed in implementation?
[14:24] <@wolfsokta> Come back Tron!
[14:24] coudl it have been implement through bip9 voting?
[14:24] also hard fork is activated by the community! that's a vote thing!
[14:24] @mrsushi to give people time to upgrade their wallet
[14:25] @under, it would be much hard to keep consensus with a bip9 change
[14:25] <@wolfsokta> We investigated that closely Under.
[14:25] == Tron [[email protected]/web/freenode/ip.173.241.144.77] has joined #ravencoin-dev
[14:25] <@wolfsokta> See Tron's post for more details about that.
[14:25] <@spyder_> Hi Tron
[14:25] <@wolfsokta> https://medium.com/@tronblack/ravencoin-dark-gravity-wave-1da0a71657f7
[14:25] Sorry about that. Computer went to sleep.
[14:26] I'm wrong
[14:26] 2 cents. the release deadline of october 31st puts a bit of strain on getting code shipped. (duh). but fixing daa was important to the current health of the coin, and was widely suppported by current mining majority commuity. could it have been implemented in a different manner? yes . if we didnt have deadlines
[14:27] == wjcgiwgu283ik3cj [[email protected]/web/freenode/ip.172.58.37.35] has quit [Quit: Page closed]
[14:27] sushi this fork does not include assets. it's not being delayed though, we're making great progress for an Oct 31 target
[14:28] I don’t see the urgency but my vote doesn’t matter since my hash power is still CPUs
[14:28] <@wolfsokta> We're seeing the community get behind the change as well based on the amount of people jumping back in to mine through this last high difficulty phase.
[14:28] So that will be another hardfork?
[14:28] the fork does include the asset code though set to activate on oct 30th
[14:28] yes
[14:29] <@wolfsokta> Yes, it will based on the upgrade voting through the BIP9 process.
[14:29] I wanted to ask about burn rates from this group: and make a proposal.
[14:29] we're also trying hard to make it the last for awhile
[14:29] Can you clear up the above — there will be this one and another hard fork?
[14:29] <@wolfsokta> Okay, we could discuss that under towards the end of the meeting.
[14:30] If this one has the asset layer is there something different set for October
[14:30] <@wolfsokta> Yes, there will be another hard fork on October 31st once the voting process is successful.
[14:31] <@wolfsokta> The code is in 2.0.4 now and assets are active on testnet
[14:31] Bruce, the assets layer is still being worked on. Assets is active on mainnet. So in Oct 31 voting will start. and if it passes, the chain will fork.
[14:31] this one does NOT include assets for mainnet Bruce -- assets are targeted for Oct 31
[14:31] not***
[14:31] not active****
[14:31] correct me if I'm wrong here, but if everyone upgrades to 2.0.4 for this fork this week, the vote will automatically pass on oct 31st correct? nothing else needs to be done
[14:31] Will if need another download or does this software download cover both forks?
[14:31] <@wolfsokta> Correct Urgo
[14:32] thats how the testnet got activated and this one shows "asset activation status: waiting until 10/30/2018 20:00 (ET)"
[14:32] Will require another upgrade before Oct 31
[14:32] thank you for the clarification wolfsokta
[14:32] <@wolfsokta> It covers both forks, but we might have additional bug fixes in later releases.
[14:32] So users DL one version now and another one around October 30 which activates after that basically?
[14:33] I understand that, but I just wanted to make it clear that if people upgrade to this version for this fork and then don't do anything, they are also voting for the fork on oct 31st
[14:33] Oh okay — one DL?
[14:33] Bruce, Yes.
[14:33] Ty
[14:33] well there is the issue that there maybe some further consensus bugs dealing with the pruneability of asset transactions that needs to be corrected between 2.0.4 and mainnet. so i would imagine that there will be further revisions required to upgrade before now and october 31
[14:33] @under that is correct.
[14:34] I would highly recommend bumping the semver up to 3.0.0 for the final pre 31st release so that the public know to definitely upgrade
[14:34] @under +1
[14:35] out of curiosity, have there been many bugs found with the assets from the version released in july for testnet (2.0.3) until this version? or is it solely a change to DGW?
[14:35] <@wolfsokta> That's not a bad idea under.
[14:35] <@spyder_> @under good idea
[14:35] @urgo. Bugs are being found and fixed daily.
[14:35] Any time the protocol needs to change, there would need to be a hard fork (aka upgrade). It is our hope that we can activate feature forks through the BIP process (as we are doing for assets). Mining pools and exchanges will need to be on the newest software at the point of asset activation - should the mining hash power vote for assets.
[14:35] blondfrogs: gotcha
[14:35] There have been bugs found (and fixed). Testing continues. We appreciate all the bug reports you can give us.
[14:36] <@wolfsokta> Yes! Thank you all for your help in the community.
[14:37] (pull requests with fixes and test coverage would be even better!)
[14:37] asset creation collision is another major issue. current unfair advantage or nodes that fore connect to mining pools will have network topologies that guarantee acceptance. I had discussed the possibility of fee based asset creation selection and i feel that would be a more equal playing ground for all users
[14:38] *of nodes that force
[14:38] <@wolfsokta> What cfox said, we will always welcome development help.
[14:38] So just to make sure everyone know. When assets is ready to go live on oct 31st. Everyone that wants to be on the assets chain without any problems will have to download the new binary.
[14:39] <@wolfsokta> The latest binary.
[14:39] under: already in the works
[14:39] excellent to hear
[14:39] == UserJonPizza [[email protected]/web/freenode/ip.24.218.60.237] has joined #ravencoin-dev
[14:39] <@wolfsokta> Okay, we've spent a bunch of time on that topic and I think it was needed. Does anybody have any other suggestions on how to get the word out even more?
[14:40] maybe preface all 2.0.X releases as pre-releases... minimize the number of releases between now and 3.0 etc
[14:41] <@wolfsokta> Bruce_ let's discuss further offline.
[14:41] wolfsokta: which are the remaining two pools that need to be upgraded? I've identified qbtc, upbit, and cryptobridge as high volume exchanges that haven't said they were going to do it yet
[14:41] so people can help reach out to them
[14:41] f2pool is notoriously hard to contact
[14:41] are they on board?
[14:42] <@wolfsokta> We could use help reaching out to QBTC and Graviex
[14:42] I can try to contact CB if you want?
[14:42] <@Chatturga> The remaining pools are Ravenminer and PickAxePro.
[14:42] <@Chatturga> I have spoken with their operators, the update just hasnt been applied yet.
[14:42] ravenminer is one of the largest ones too. If they don't upgrade that will be a problem
[14:42] okay good news
[14:42] (PickAxePro sounds like a Ruby book)
[14:43] I strongly feel like getting the word out on ravencoin.org would be beneficial
[14:44] that site is sorely in need of active contribution
[14:44] Anyone can volunteer to contribute
[14:44] <@wolfsokta> Okay, cfox can you talk about the status of unique assets?
[14:44] sure
[14:45] <@wolfsokta> I'll add website to the end of our topics.
[14:45] code is in review and will be on the development branch shortly
[14:45] would it make sense to have a page on the wiki (or somewhere else) that lists the wallet versions run by pools & exchanges?
[14:45] will be in next release
[14:45] furthermore, many sites have friendly link to the standard installers for each platform, if the site linked to the primary installers for each platform to reduce github newb confusion that would be good as well
[14:46] likely to a testnetv5 although that isn't settled
[14:46] <@wolfsokta> Thanks cfox.
[14:46] <@wolfsokta> Are there any questions about unique assets, and how they work?
[14:47] after the # are there any charachters you cant use?
[14:47] will unique assets be constrained by the asset alphanumeric set?
[14:47] ^
[14:47] <@Chatturga> @Urgo there is a page that tracks and shows if they have updated, but it currently doesnt show the actual version that they are on.
[14:47] a-z A-Z 0-9
[14:47] <@Chatturga> https://raven.wiki/wiki/Exchange_notifications#Pools
[14:47] There are a few. Mostly ones that mess with command-line
[14:47] you'll be able to use rpc to do "issueunique MATRIX ['Neo','Tank','Tank Brother']" and it will create three assets for you (MATRIX#Neo, etc.)
[14:47] @cfox - No space
[14:48] @under the unique tags have an expanded set of characters allowed
[14:48] Chatturga: thank you
[14:48] @UJP yes there are some you can't use -- I'll try to post gimmie a sec..
[14:49] Ok. Thank you much!
[14:49] 36^36 assets possible and 62^62 uniques available per asset?
[14:49] <@spyder_> std::regex UNIQUE_TAG_CHARACTERS("^[[email protected]$%&*()[\\]{}<>_.;?\\\\:]+$");
[14:50] regex UNIQUE_TAG_CHARACTERS("^[[email protected]$%&*()[\\]{}<>_.;?\\\\:]+$")
[14:50] oh thanks Mark
[14:51] <@wolfsokta> Okay, next up. I want to thank everybody for helping test the iOS wallet release.
[14:51] <@wolfsokta> We are working with Apple to get the final approval to post it to the App Store
[14:51] @under max asset length is 30, including unique tag
[14:51] Does the RVN wallet have any other cryptos or just RVN?
[14:52] == BruceFenton [[email protected]/web/freenode/ip.67.189.233.170] has joined #ravencoin-dev
[14:52] will the android and ios source be migrated to the ravenproject github?
[14:52] I've been adding beta test users. I've added about 80 new users in the last few days.
[14:52] <@wolfsokta> Just RVN, and we want to focus on adding the asset support to the wallet.
[14:53] == Bruce_ [[email protected]/web/freenode/ip.67.189.233.170] has quit [Ping timeout: 252 seconds]
[14:53] <@wolfsokta> Yes, the code will also be freely available on GitHub for both iOS and Android. Thank you Roshii!
[14:53] Would you consider the iOS wallet to be a more secure place for one's holdings than say, a Mac connected to the internet?
[14:53] will there be a chance of a more user freindly wallet with better graphics like the iOS on PC?
[14:53] the android wallet is getting updated for DGW, correct?
[14:53] <@wolfsokta> That has come up in our discussion Pizza.
[14:54] QT framework is pretty well baked in and is cross platform. if we get some qt gurus possibly
[14:54] Phones are pretty good because the wallet we forked uses the TPM from modern phones.
[14:54] Most important is to write down and safely store your 12 word seed.
[14:54] TPM?
[14:54] <@wolfsokta> A user friendly wallet is one of our main goals.
[14:55] TPM == Trusted Platform Module
[14:55] Ahhh thanks
[14:55] just please no electron apps. they are full of security holes
[14:55] <@spyder_> It is whats makes your stuffs secure
[14:55] not fit for crypto
[14:55] under: depends on who makes it
[14:55] The interface screenshots I've seen look like Bread/Loaf wallet ... I assume that's what was forked from
[14:55] ;)
[14:56] <@wolfsokta> @roshii did you see the question about the Android wallet and DGW?
[14:56] Yes, it was a fork of breadwallet. We like their security.
[14:56] chromium 58 is the last bundled electron engine and has every vuln documented online by google. so unless you patch every vuln.... methinks not
[14:56] Agreed, great choice
[14:57] <@wolfsokta> @Under, what was your proposal?
[14:58] All asset creation Transactions have a mandatory OP_CHECKLOCKTIMEVERIFY of 1 year(or some agreed upon time interval), and the 500 RVN goes to a multisig devfund, run by a custodial group. We get: 1) an artificial temporary burn, 2) sustainable community and core development funding for the long term, after OSTK/Medici 3) and the reintroduction of RVN supply at a fixed schedule, enabling the removal of the 42k max cap of total As
[14:58] *im wrong on the 42k figure
[14:58] <@wolfsokta> Interesting...
[14:59] <@wolfsokta> Love to hear others thoughts.
[14:59] Update: I posted a message on the CryptoBridge discord and one of their support members @stepollo#6276 said he believes the coin team is already aware of the fork but he would forward the message about the fork over to them right now anyway
[14:59] Ifs 42 million assets
[14:59] yep.
[15:00] I have a different Idea. If the 500 RVN goes to a dev fund its more centralized. The 500 RVN should go back into the unmined coins so miners can stay for longer.
[15:01] *without a hardfork
[15:01] <@wolfsokta> lol
[15:01] that breaks halving schedule, since utxos cant return to an unmined state.
[15:01] @UJP back into coinbase is interesting. would have to think about how that effects distribution schedule, etc.
[15:01] only way to do that would be to dynamicaly grow max supply
[15:02] and i am concerned already about the max safe integer on various platforms at 21 billion
[15:02] js chokes on ravencoin already
[15:02] <@wolfsokta> Other thoughts on Under's proposal? JS isn't a real language. ;)
[15:02] Well Bitcoin has more than 21 bn Sats
[15:02] Is there somebody who wants to volunteer to fix js.
[15:02] hahaha
[15:03] I honestly would hate for the coins to go to a dev fund. It doesn't seem like Ravencoin to me.
[15:03] Yep, but we're 21 billion x 100,000,000 -- Fits fine in a 64-bit integer, but problematic for some languages.
[15:03] <@wolfsokta> Thanks UJP
[15:04] <@wolfsokta> We're past time but I would like to continue if you folks are up for it.
[15:04] Yeah no coins can go anywhere centrality contorted like a dev fund cause that would mean someone has to run it and the code can’t decide that so it’s destined to break
[15:05] currently and long term with out the financial backing of development then improvements and features will be difficult. we are certainly thankful for our current development model. but if a skunkworks project hits a particular baseline of profitability any reasonable company would terminate it
[15:05] Yes let’s contibue for sure
[15:05] the alternative to a dev fund in my mind would be timelocking those funds back to the issuers change address
[15:06] But we can’t have dev built in to the code — it has to be open source like Bitcoin and monero and Litecoin - it’s got drawbacks but way more advantages- it’s the best model
[15:06] Dev funding
[15:06] i highly reccommend not reducing the utility of raven by removing permanently the supply
[15:07] == BW_ [[email protected]/web/freenode/ip.138.68.243.202] has joined #ravencoin-dev
[15:07] timelocking those funds accompllishes the same sacrifice
[15:07] @under timelocking is interesting too
[15:07] How exactly does timelocking work?
[15:07] <@wolfsokta> ^
[15:07] I mean you could change the price of assets with the Block reward halfing.
[15:07] == Roshiix [[email protected]/web/freenode/ip.105.67.2.212] has joined #ravencoin-dev
[15:08] funds cant be spent from an address until a certain time passes
[15:08] but in a what magical fairy land do people continue to work for free forever. funding development is a real issue... as much as some might philosphically disagree. its a reality
[15:08] You’d still need a centralized party to decide how to distribute the funds
[15:08] even unofficially blockstream supports bitcoin devs
[15:08] on chain is more transparent imho
[15:09] == Tron_ [[email protected]/web/freenode/ip.173.241.144.77] has joined #ravencoin-dev
[15:09] @UJP yes there are unlimited strategies. one factor that I think is v important is giving application developers a way to easily budget for projects which leads to flat fees
[15:09] If the project is a success like many of believe it will be, I believe plenty of people will gladly done to a dev fund. I don't think the 500 should be burned.
[15:09] *donate
[15:09] centralized conservatorship, directed by community voting process

[15:10] <@wolfsokta> Thanks Under, that's an interesting idea that we should continue to discuss in the community. You also mentioned the existing website.
[15:10] It would need to be something where everyone with a QT has a vote
[15:10] think his computer went to sleep again :-/
[15:10] I agree UJP
[15:10] with the website
[15:10] No that’s ico jargon — any development fund tied to code would have to be centralized and would therefor fail
[15:11] ^
[15:11] ^
[15:11] ^
[15:11] dashes model for funding seems to be pretty decentralized
[15:11] community voting etc
[15:11] Once you have a dev fund tied to code then who gets to run it? Who mediates disputes?
[15:11] oh well another discussion
[15:11] Dash has a CEO
[15:12] <@wolfsokta> Yeah, let's keep discussing in the community spaces.
[15:12] Dash does have a good model. It's in my top ten.
[15:12] having the burn go to a dev fund is absolute garbage
[15:12] These dev chats should be more target than broad general discussions — changing the entire nature of the coin and it’s economics is best discussed in the RIPs or other means
[15:13] <@wolfsokta> Yup, let's move on.
[15:13] just becuase existing implementation are garbage doesnt mean that all possible future governance options are garbage
[15:13] <@wolfsokta> To discussing the website scenario mentioned by under.
[15:13] the website needs work. would be best if it could be migrated to github as well.
[15:13] What about this: Anyone can issue a vote once the voting feature has been added, for a cost. The vote would be what the coins could be used for.
[15:14] features for the site that need work are more user friendly links to binaries
[15:14] <@wolfsokta> We investigated how bitcoin has their website in Github to make it easy for contributors to jump in.
[15:14] that means active maintenance of the site instead of its current static nature
[15:15] <@wolfsokta> I really like how it's static html, which makes it super simple to host/make changes.
[15:15] the static nature isn’t due to interface it’s due to no contributors
[15:15] no contribution mechanism has been offered
[15:15] github hosted would allow that
[15:16] We used to run the Bitcoin website from the foundation & the GitHub integration seemed to cause some issues
[15:16] its doesnt necessarily have to be hosted by github but the page source should be on github and contributions could easily be managed and tracked
[15:17] for example when a new release is dropped, the ability for the downlaods section to have platform specific easy links to the general installers is far better for general adoption than pointing users to github releases
[15:18] <@wolfsokta> How do people currently contribute to the existing website?
[15:18] they dont?
[15:18] We did that and it was a complete pain to host and keep working — if someone wants to volunteer to do that work hey can surely make the website better and continually updated — but they could do that in Wordpress also
[15:19] I’d say keep an eye out for volunteers and maybe we can get a group together who can improve the site

Most alt-coins are NOT secure enough, they exist only for entertainment and speculation

(I believe this needs to be posted to /bitcoin as Bitcoin users/enthusiasts need to know the difference between Bitcoin and other cryptocurrencies. About author: I'm subscribed to /bitcoin since 2011, and have been involved in cryptocurrency security research for several years.)
Let's talk about security aspect of cryptocurrencies. I'm afraid an average user knows very little about this topic: he might know that hashrate is needed to protect the blockchain, and that higher hashrate is better, as it implies that attacker needs to spend more to get control of the blockchain.
But there is a plenty of other kinds of attacks (or, rather, economic models of attacks), some of which have much higher practical significance.
Let's start with something simple: there is a straightforward and rigorous model of double-spending attack under condition that attacker has a fraction of total network's hashrate. I highly recommend Meni Rosenfeld's Analysis of hashrate-based double-spending paper (PDF).
The main takeaway from this paper is that "maximal safe transaction value" is directly proportional to block reward (i.e. amount of coins miners get for each block). It is easy to understand this intuitively: bigger reward means that miners get more money from normal mining, so they will be reluctant to try double-spending attacks. On the other hand, if block reward was negligible, double-spending could be a lucrative source of revenue.
Let's look at numbers: if attacker controls 26% of hashrate and number of confirmations is 6, maximal safe transaction value is 1113 BTC when block reward is 25 BTC. This is pretty cool: you only need to wait 1 hour to make sure you irreversibly received half million USD worth of bitcoins (I assume exchange rate of $450 for 1 Bitcoin).
However, situation is pretty different for alt-coins which have much less valuable block rewards. For example, imagine there is a Foocoin with exchange rate of $1 for 1 Foocoin. If Foocoin's block reward is also 25 foocoins, then max save transaction value for 6 confirmations is only $1113 USD worth of Foocoins. It doesn't look like Foocoin is suitable for commerce, does it?
One could say that Foocoin simply requires larger number of confirmations for larger transactions. But that's wrong: higher number of confirmations helps only under condition that attacker is unable to obtain more than 50% of total hashrate, but for most alt-coins it isn't true.
First of all, let's note that so-called miners simply rent their equipment to "mining pool operators" and are paid in crypto-currency for it. In many cases they don't even care what cryptocurrency they mine as long as they are being paid. See Middlecoin:
This pool automatically mines the most profitable scrypt coin, automatically exchanges those coins for bitcoins, and pays out entirely in bitcoins.
So, miners who mine using Middlecoin do not know if their equipment is being used to mine Litecoins or Dogecoins or something else. And they wouldn't care if it is used for attacks on alt-coins, as they are being paid in bitcoins.
Let's consider a scenario where Middlecoin-like pool has higher hashrate than Foocoin, e.g. Middlecoin (not Middlecoin specifically, but any pool like that) has 20 GH/s, while Foocoin has 10 GH/s. Here's how one can profit from it:
  1. Buy $1M worth of Foocoins, get them into your wallet.
  2. Make an agreement with Middlecoin: you rent they hashrate for a couple of hours, paying them in bitcoin, slightly above what most profitable alt-coin yields.
  3. Send your foocoins to exchange Bar.
  4. Start mining a private chain which has a double-spend transaction which sends coins to exchange Baz.
  5. After your transaction gets 10 confirmations on the normal chain, convert foocoins to bitcoins on Bar and withdraw them immediately.
  6. After withdrawal transaction is confirmed on Bitcoin network (and thus cannot be reversed), you release the private chain you have mined, causing reorganization. You should have mined 20 blocks by then under if Middlecoin has hashrate which is twice higher than normal Foocoin's hashrate.
  7. Your deposit to exchange Baz is now confirmed, converl your foocoins to bitcoins again, and withdraw immediately.
  8. A day later 20 blocks you have mined will get mature, and you'll be able to sell them too.
If Foocoin price doesn't change in process, you can get approximately $1M profit on this attack, as cost of renting a mining pool is approximately equal to value of mined blocks.
In practice, you'll lose some money due to lack of liquidity on exchanges, so profit will be less than $1M.
The conclusion we get from this analysis is that alt-coins which have only a small fraction of total hashrate for a certain mining algorithm are extremely non-secure. And they cannot grow big: as soon as exchanges will have enough liquidity, it will be possible to perform the attack I described, which will result in the price drop.
So almost all alt-coins are simply not suitable for any kind of "real economy" applications. They are doomed to have high volatility, shallow markets, low "max safe transaction value".
One can't deny the fact that it is possible to make money on alt-coins. But that's just gambling. And people who create new alt-coins are in same position as people who build casinos. It is a business, but it is the entertainment sector, not in 'real economy' or 'financial' sectors as some people are trying to pretend.
Bitcoin is one of few cryptocurrencies which are actually serious. It isn't perfect, but attacking Bitcoin is very hard, so transactions worth millions of dollars can be confirmed in matter of hours. Same cannot be said about alt-coins, and this situation won't change unless new cryptocurrency designs will be found.
If there is an alt-coin which is more-or-less secure, it is probably Litecoin. Its hashrate is a significant fraction of total scrypt hashrate, so attacking Litecoin is hard. Interestingly, at some point Dogecoin's hashrate was higher than Litecoin's but it dropped after block reward have dropped. So, again, block reward is important for security.
This has dire implications for alt-coins which have short block reward schedules. If all coins will be mined in two years, this mean that alt-coin will be dead in two years.
(It's worth noting that same problem might affect Bitcoin in future, like in 10 years or so.)
Now there is a question: Is there a way to make multiple currencies all of which will be secure?
Probably. There are several approaches:
  1. Merged mining: The idea is that Bitcoin's proof-of-work can be re-used to mine alt-chains. This makes attacks harder, but hashrate-based double-spending considerations are still applicable, so safety can't be guaranteed... They will be safe only if miners are benevolent.
  2. Side-chains: This needs more research, but it looks like high degree of security is possible as long as you don't care about SPV.
  3. Proof-of-stake and PoW/PoS hybrid: Needs more research, there is some hope. Note that Peercoin's PoS is pretty bad.
  4. Multiple cryptocurrencies in the same blockchain (e.g. colored coins, Mastercoin, Counterparty, Ethereum, Ripple, etc.) will all be equally secure, so I believe this is what we should do instead of spawning a shitload of alt-coins.

Has the Bitcoin Hash Rate Peaked? Comparisons with Oil Show Interesting Findings

Has the Bitcoin Hash Rate Peaked? Comparisons with Oil Show Interesting Findings

https://preview.redd.it/85lpl2md4e221.png?width=690&format=png&auto=webp&s=2d3bab69f0570a96f55d790d25f1b1ab08c0a49b
https://cryptoiq.co/the-bitcoin-mining-hash-rate-has-similarities-to-peak-oil/
The Bitcoin mining hash rate had been exponentially increasing on average since the genesis block in 2009, from MH/s, to GH/s, to TH/s, to PH/s, to EH/s, and it reached an all-time record high of 62 EH/s on 26 August 2018. Since this peak was reached, the Bitcoin mining hash rate gradually plateaued and has now decreased. The chart of Bitcoin mining hash rate actually looks quite similar to a peak oil chart except on a much faster time-scale, as can be seen in the comparison between Bitcoin’s hash rate over the course of 2 years from Blockchain.com and North Sea oil production from an article in The Oil Drum: Europe by Euan Mearns. As explained below, the dynamics between peak oil and peak Bitcoin mining are similar, with the key difference that Bitcoin mining is decentralized and oil is not.

https://preview.redd.it/op5ept1g4e221.png?width=512&format=png&auto=webp&s=2b3b35eb631f31a64ed7beb01f283832bd231e4c

https://preview.redd.it/nfyhlf4h4e221.png?width=678&format=png&auto=webp&s=46a0ca7e11f274c5678f6421b1eebb788eab5197
Geologist M. King Hubbert is the founder of the peak oil theory, which states that there is a point when the maximum extraction rate of petroleum is reached, after which a terminal decline in production ensues. The peak rate of extraction of Bitcoin of course occurred during the period after the genesis block and before the first block halving, when the block reward was at its maximum of 50 Bitcoins. However, this is not the peak rate of mining profitability, since Bitcoin increased in price by orders of magnitude through the year 2017. The peak rate of Bitcoin mining profits undoubtedly was simultaneous with Bitcoin’s all-time record high of USD 20,000 in December 2017.
The reason the peak hash rate did not coincide with the peak rate of Bitcoin mining profits is because the rally happened so quickly that mining operations were not able to add rigs fast enough, so there was a lag effect. Even for mining operations with large amounts of capital it can take months to obtain the amount of mining equipment that they want, and for other mining operations it took even longer because they had to obtain investors, buy land, build infrastructure, and only then could they install the rigs and begin hashing.
The Bitcoin mining hash rate chart implicitly indicates that 30 EH/s of Bitcoin mining equipment has been taken offline due to lack of profitability, which represents tens of billions of USD of wasted rigs. This suggests that Bitcoin miners were caught by surprise by the decline in Bitcoin’s price from USD 20,000 to less than USD 4,000 as of 4 December 2018.
Coming back to the peak oil comparison, the current Bitcoin mining scene is like a rapid version of peak oil, combined with lack of coordination. Oil mining is a centralized and coordinated activity, where the oil is prospected, land is leased out and then an appropriate number of wells are drilled. With oil mining, companies cannot drill as many wells as they want, or drill wells on someone else’s lease, since this is all closely controlled by contractual agreements. Bitcoin mining is decentralized, and no one has a lease or contract to only mine with a certain amount of hash rate. Anyone in the world can run as much Bitcoin mining rigs as they can afford. The effect is that people all around the world are sticking their straws into the Bitcoin mining network all at the same time, and they sucked it dry. Essentially, so many people started up new mining operations at once without coordination, that the Bitcoin mining hash rate went way past its equilibrium, which hurt everyone involved. This is akin to if oil drilling was a decentralized process, and anyone who wanted to drill for oil could drill in the same field. The oil field would be sucked dry really quick, and then most of the drills would be shut down due to lack of profits.
There is hope for Bitcoin miners however. The price of Bitcoin simply has to rally, and all of the disenfranchised miners could restart their rigs, and then it would be back to the races and new rigs could begin being added. However, due to the decentralization of Bitcoin mining, the network hash rate will likely periodically rise past its equilibrium point, leading to catastrophic conditions for miners like we are experiencing today at points in the future. The only thing that could prevent the scenario we are experiencing today is a Bitcoin rally that lasts forever, which is obviously not possible.
James McAvity tweeted that Bitcoin mining is still profitable in the current environment, and does some simple linear calculations to prove this point. He also argues that miners are forced to keep mining due to business agreements, choose to HODL in expectation of a rally, and continue mining in expectation of a downward difficulty adjustment as other miners go offline.
https://twitter.com/jamesmcavity/status/1069669073552736256
Some of what McAvity says is true, but the reality is that Bitcoin mining is a highly non-linear system, and calculating the support level for mining is somewhat pointless, since it is different for every miner. Bitcoin mining profitability depends on Bitcoin’s price, the Bitcoin network hash rate which is directly correlated to mining difficulty, and the technological efficiency of Bitcoin mining rigs. These 3 factors are related in a non-linear and ever-changing way.
Instead of trudging away at trying to develop a set of equations that determine mining hash rate behavior, one could simply look at the Bitcoin mining hash rate chart at the beginning of this article to understand what is going on. Bitcoin mining profitability is different for each individual miner, and the hash rate has trended downwards as individual miners have made the decision to shut down rigs. Clearly there was a fundamental mining profitability support level in the USD 6,000-7,000 range, since that is where Bitcoin’s price was when mining peaked and plateaued. There are clearly numerous miners who became unprofitable on the descent from that level to less than USD 4,000 today, and now approximately 50% of the Bitcoin mining equipment that exists cannot profitably mine. The decrease in Bitcoin’s mining difficulty of 15% on 3 December 2018 could help bring some of those miners back online, at least if the price stays at current levels around USD 4,000, but this will not change the overall trend.
When it comes down to it, Bitcoin’s price is in control of Bitcoin mining profitability, and if the price goes up we could see a reversal of the hash rate downtrend and eventually a 2nd peak in Bitcoin’s network hash rate. However, if price continues to go down, the Bitcoin mining hash rate chart will follow a similar pattern to peak oil charts. The reality will likely be a combination of both. Bitcoin bear markets tend to last years, and get more severe, but eventually the rally comes and then Bitcoin exceeds its all-time record high. This would lead to a steady decrease in Bitcoin’s mining hash rate like the peak oil chart, followed by a rapid re-engagement of old mining rigs that have been taken offline, and then the addition of new generation Bitcoin mining rigs once the equilibrium hash rate exceeds 60 EH/s.

Some general stuff that's been happening lately:
  1. Userbrn's community fund reached 0.1 BTC and the application was submitted to list on YoBit. There hasn't been any feedback from the exchange yet, hopefully some new information surfaces over the course of the week.
  2. User dave牟 talked about an upcoming DEX, which will have 0xBTC as one of its main trading pairs. From the Discord: "By the way my project received 1000ETH in angel funding /.../ we will have trading pairs in ETH, DAI and 0xBTC it will be online in about 3 months. We also have an interesting “gameified” listing process that is kind of like fomo3d."
  3. Ethereum core developers decided to cut block rewards from 3 ETH to 2 ETH with the upcoming Constantinople hard fork in late October. This just goes to show how opaque and mutable Ether's monetary policy is.
  4. Talking about ETH - its price has been in a total trashfire for the last few weeks. Several high-profile articles have said that the pump to $1,400 was completely artificial and only driven by ICO's, a large part of which are slowly beginning to crash and burn. It's only a matter of time before people begin searching for an Ethereum-compatible store of value, and those people will find 0xBTC already waiting for them. The article that spurred most of the recent debate: https://techcrunch.com/2018/09/02/the-collapse-of-eth-is-inevitable/amp/
  5. When replying to the above article, Vitalik described a new possible way of transacting tokens on the Ethereum network: "One could also use intermediate solutions, where third parties create "wrapper transactions" that take the fees for operations from users that are paid in spankchain tokens, and the third parties provide the ETH to the block proposer". This is exactly the idea behind LavaWallet, and the comment caused the price of 0xBTC to spike over a 100%.
  6. User MyCryptoDad had a meeting with a crypto influencer, whom he advertised 0xBTC to. After the meeting, he said: "Came back from the Meetup with the influencer, he and the rest of the crew never heard of it. Good and bad, good that we are under the radar to accumulate, bad because we might be too under the radar. They seemed interested in the details behind it like fair distribution, the founder is mining on a 1060, no airdrop etc... Other good news to come out I was invited to their telegram group and meetups. The influencer also said he'd be willing to work with me on an idea. I'll be seeing these people a bit more. I'm telling everyone here because I believe in this project (0xBitcoin) and I want to see us succeed as organically as possible. I'll keep spreading the good word." I guess we'll just have to wait and see what comes of it.
  7. Mr Fahrenheit released "Wheel of 0xBitcoin", the first dapp built specifically for 0xBTC. It's basically a decentralized way to gamble, you can be sure that the odds aren't rigged against you and it doesn't serve only to enrich its creators. When the house wins, then the prize doesn't go to the creator, but to the smart contract, which then pays winners out of the fund. You can also keep the money in the contract without gambling, in which case you will be gaining money when people gamble and lose (but also losing money, when they gamble and win). The developers receive money in the form of a 3% deposit fee. http://wheelof0xbitcoin.io/

Ethereum Classic (ETC) Hit With 51 Percent Attack A Week Before Ethereum (ETH) Constantinople Hard Fork

Ethereum Classic (ETC) Hit With 51 Percent Attack A Week Before Ethereum (ETH) Constantinople Hard Fork

https://cryptoiq.co/ethereum-classic-etc-hit-with-51-percent-attack-a-week-before-ethereum-eth-constantinople-hard-fork/
Ethereum Classic (ETC), which is listed on Coinbase and ranked number 17 on CoinMarketCap with a market cap near $550 million, has been hit with a 51 percent attack. The attack appears to have occurred from 9 p.m. Jan. 6 to just after midnight on Jan. 7 and resulted in a blockchain reorganization hundreds of blocks deep. This news is just breaking now, and ETC’s price is down 7 percent, shaving $40 million off its market cap.

The number of double spends during this 51 percent attack, if any, is unknown at this time. It is recommended to wait for 400 plus confirmations before accepting any Ethereum Classic (ETC) transaction.

This 51 percent attack on Ethereum Classic comes a little over a month after the dev team which maintained the main ETC client walked out due to lack of funding.

There is no obvious linkage between the primary dev team walking out and this 51 percent attack; however, Ethereum Classic (ETC) appears to be in dire straits. A 51 percent attack is enough to ruin the reputation of any cryptocurrency since it makes users lose confidence that a cryptocurrency is immutable and secure. The primary dev team walking out around the same time adds insult to injury.
Community Outcry For ProgPoW To Block ASICs
Ethereum’s (ETH) Constantinople hard fork is scheduled to occur in about a week, and one of the key points of contention during the fork is that mining rewards will be slashed from three Ether to two. Also, the Ethereum developers are considering including ProgPoW in the fork, which would block ASIC miners.
It seems this 51 percent attack on Ethereum Classic is being used as justification to implement ProgPoW for both Ethereum (ETH) and Ethereum Classic (ETC). The 51 percent attack is being blamed on new 1.4 GH/s ASIC ETHash rigs although this is just speculation and not confirmed.

Ethereum (ETH) and Ethereum Classic (ETC) users are crying out for an immediate block of ASIC miners, saying this 51 percent attack is proof that blocking ASICs with ProgPoW is urgent.

The timing of this 51 percent attack on Ethereum Classic (ETC), a week before the Ethereum (ETH) Constantinople hard fork, is interesting. There is still enough time to block ASIC miners by including ProgPoW in the fork if there is a big enough outcry from the community.
Ethereum (ETH) miners are left in a poor situation. Not only are block rewards being slashed, but ASICs also may be blocked with ProgPoW due to this 51 percent attack on Ethereum Classic (ETC). Now, Ethereum (ETH) miners who use ASICs have no good mining alternative since Ethereum Classic (ETC) was probably the best alternative in the event that Ethereum (ETH) blocks ASICs. It seems probable that Ethereum Classic (ETC) will implement ProgPoW as well, so it will no longer be an alternative for ASIC miners.
CryptoIQ speculated about 1 month ago that the Ethereum Constantinople hard fork could lead to a new version of Ethereum that is favorable for miners, possibly resulting in a similar situation to the “Bitcoin Cash War” in November 2018. The increased pressure to block ASICs following the Ethereum Classic (ETC) 51 percent attack combined with ETC likely implementing ProgPoW as well perhaps increases the likelihood that a completely new version of Ethereum will form when Constantinople arrives.
