Addressing the many concerns related to Obelisk

Why make ASICs at all?

Our blog has a longer post on the subject, but the ultimate answer is that GPU mining is very insecure. For the vast majority of GPU mined coins out there (including Sia), it is the case that there are multiple, if not many, individuals who operate enough GPUs to execute a 51% attack against the coin all by themselves. There are some very large Ethereum GPU farms out there, and they are a threat to all small GPU-mined coins. (our market cap is a factor of 50 smaller than Ethereum - we are a small coin). And it's not just Ethereum farms to be afraid of, there are massive GPU farms dedicated to machine learning as well, and other big-data related use cases. All of those are potential sources for a 51% attack. Even worse, if the price of the coin tanks following such an attack, the attacker has nothing to lose, because the core purpose of their hardware is unrelated to Sia, and unaffected by a change in price.
Though it sounds terrible and unintuitive, a single centralized entity running ASICs would be a much more secure situation than this. Because with a single central ASIC entity, you get two huge advantages:
  1. There's only 1 entity capable of performing a 51% attack. This is much better than having multiple entities that are each individually capable of performing a 51% attack.
  2. If the price of the coin falls, the entity that has all of the hardware loses a lot of money. That hardware isn't good for anything besides Sia mining, so that entity is quite invested in propping up the siacoin price.
We chose ASICs over GPUs because even the worst case scenario is more secure and better for the coin than the situation with GPU mining.
But we also did not want a single entity owning and operating all of the ASICs. That's when we realized, if we were ASIC manufacturers ourselves, we could guarantee that at least one entity is selling chips to the larger community. The unfortunate fact is that either way, there is going to be a small number of chip manufacturers who have the power to sell chips to the community. Even so, this is a better situation than what you get with GPU mining.
We are making ASICs so that we can guarantee the first batch of ASICs will make it to the Sia community. Without that, we have no idea if the first batch of ASICs will be sold to the public or hoarded by some greedy investors who were able to pay the full price of manufacturing up-front.

Why are you doing the presale so early?

We, put simply, don't have enough cash even to do the early development of the chips. We need financing to pay for chip development.
Traditionally, we would find some private investors, have them front some millions, and in return promise them a very good deal on some hardware. The private investors would get the first stab at buying ASICs, they'd get a huge chunk, and they'd get them at an exclusive deal for taking on the risk early. We actually had private investors come forward offering this to us, with enough money to fund the full development and manufacture of the first batch of chips - this isn't a hypothetical, it's a real offer that the Sia team received.
This didn't seem fair to us. When we finally did get to the point where the miners were ready to be sold to the community, we would have to offer the community a worse deal. Less risky, but ultimately it would mean that the community was excluded from the opportunity of participating early, and the result is a huge chunk of the chips going to some private investors.
Such a situation is still better than GPU mining, but it didn't seem like the best that we could do. We felt that we could do better by opening the early presale to everyone.

Why not accept credit cards?

Payment processors are not friendly to Bitcoin products. We contacted Stripe and were told point-blank that they would not process payments for cryptocurrency miners. We appreciate everyone who pointed us towards Stripe as a bitcoin-friendly company, but they gave us a direct no.
Paypal has a long history of freezing merchant accounts with little warning, and when they do so they freeze your existing money in addition to freezing incoming payments - we would be unable to pay our bills if Paypal did this to us, and it would unquestionably cause delays. Visa and MasterCard are not much better in terms of track record.
Losing access to our accounts would unquestionably cause delays. ASIC hardware is already well known to suffer from serious delays, and we need to limit our exposure to delays.
We are in an industry that is unfortunately fraught with fraud. With revenue-generated devices such as miners, criminals are much more likely to try to target these devices as a way to cash in on stolen credit cards, stolen identities, hacked bank accounts, etc. The fraud rates are staggering, and as a result most payment processors outright refuse to deal with it. We are aware that Bitmain is partnered with Paypal, though we don't know the details behind how that came to be.

Why not accept Siacoin?

This was a harder decision. We could quite easily choose to accept siacoin, however we fear that Siacoin is not ready to handle such a massive presale. The market cap and daily volume of Bitcoin is a factor of 100 times as large as the Siacoin market cap and volume. Moving millions or tens of millions of dollars through Bitcoin is not likely to make much of a dent. Siacoin on the other hand, a sudden sell order for millions of dollars would likely tank the price. That not only means the ecosystem is unhappy with us, it also means that we might only be able to sell $2499 of siacoin for $2200.
A lot of people have accused us of not having confidence in our own coin. Unfortunately, this is true. Even at a $500 million market cap, Sia is not ready to handle a presale of this size. It's a pragmatic decision based on the fact that we don't want to dump our own coin. We know that people will be selling siacoin to buy the miners anyway, but we still feel that this situation is much better than us accepting siacoin directly.
This decision was a disappointment for us as well. We would love to accept siacoin, and if we weren't talking about processing millions of dollars in a single day, we absolutely would be accepting siacoin. And, as Sia continues growing up, the concerns above will become less and less.

What about this 5% gains/losses stuff?

Our intention was never to play fishy financial games with our users, and honestly this isn't even something that crossed our minds as a potential problem point. I think a big part of the issue was that people did not realize we will be converting to US dollars as fast as possible - we will be doing the conversion in minutes or hours as long as we can keep up with the order volume.
The rationale is very simple. If the price plummets before we are able to convert the Bitcoin, we won't have enough money to create the hardware. We really don't expect this to matter, because we don't expect the price to swing by more than $100 (which is what would be required) in the few hours that we're going to be sitting on the BTC. If it does, we'll need more coins or we can't produce the hardware - our costs are in dollars, which means we need to end up with the right amount of dollars in our account at the end of the day.
The original stance on not returning gains was also very simple. There's no transparency into when we sell the coins. If we sell the coins within 60 minutes of receiving them, and then 4 hours later there's a huge surge in the price, we will almost certainly have users emailing us and posting about how we owe them a refund. We won't have that refund, because we'll have sold the coins before the price rise.
There's not much we can do to provide transparency into this either. And we're likely to get requests for refunds even if it takes 3 months for Bitcoin to rise by 5%. This promise of returning gains that we've put forward is going to be a massive headache, because we're not expecting to have any gains, even if the price goes up by that much we'll have likely converted to USD faster than that. Our whole goal is to convert to USD as fast as possible.
We're sorry that we have to go through this headache at all. If we could get set up with a processor like Stripe, we could accept both Bitcoin and USD and let them deal with the conversion process, slippage risk, and all the other headache associated with using multiple currencies.

Why shipping a full 12 months away?

Before we set out to make Sia miners, we did a study of companies who had previously sold and pre-sold Bitcoin miners. This included talking to both Avalon and Butterfly Labs, and talking to professionals and advisors who have shipped hardware successfully in other industries. The core piece of advice we got was pretty consistent: expect delays. Expect lots of delays, and expect them to come from the most absurd setbacks. (Example: one of the people we talked to had to delay their product because there was a global shortage of power supplies, and they had to wait in line behind billion dollar companies to get some).
Our projections indicate that if all goes well, we should be able to ship the miners in 6-8 months. Nothing we are doing is new. Plenty of companies have gone through the process of developing a chip, manufacturing it, putting it in a box, and then shipping it to users. There is almost no innovation risk here. Sia's PoW algorithm is deliberately very ASIC friendly, even more than Bitcoin. We have advisors who have gone through this process before, and the types of challenges facing us are well known.
6-8 months is reasonable, except that every single person we've talked to has told us that unexpected delays is a guarantee, and that by nature of being unexpected, there's not really any way to prevent them by planning around them. Delays are just inherent to shipping hardware. So we chose to set our target at 12 months.
We will ship the miners as soon as they are ready. If we are a few months ahead of schedule, and have somehow managed to avoid the foretold delays, we will ship them months ahead of schedule. But we want our users to have a realistic understanding of the expected delays. We've baked a generous amount of time for setbacks into our shipping date. We'll almost certainly need at least some of it.

Why $2499?

Making chips is very expensive. We have to sell thousands of units to cover the cost of the chips. A nontrivial percentage of the price is going to go towards chassis, shipping, power supply, control board, fans, etc. Those costs are relatively the same even if we put in fewer chips, which means the total percentage of our budget going towards chips drops significantly. If we cut the price in half, we'll have to sell roughly three times as many units to break even on the cost of the chips. If we cut the price in half again, we'd need to sell a completely unreasonable number of units to break even on the cost of the chips. It's unfortunate, but the fixed costs of chip manufacture means that we really need vast majority of the price of the unit to be spent on chips, otherwise we simply won't be able to sell enough units.
There is a second reason as well. As stated in the section above, the industry is plagued by delays an unexpected expenses. We need a healthy budget to plan around potential setbacks, because we've been guaranteed that there will be multiple significant setbacks by those who have gone through this process before. If we bring down the price of the unit, we will also be reducing the amount of wiggle room we have for disaster if suddenly we have to replace parts, re-do designs, or otherwise perform expensive adjustments to our plans.

Are you guys qualified to be working on hardware?

Zach is a mechanical engineer, I've been in the Bitcoin space since before ASICs started shipping, and we have advisors who have successfully shipped hardware before. The team that is designing the chips for the miner has designed chips and shipped chips for Bitcoin miners previously - they are familiar with the whole process, and have done it before. The people in charge of designing the PCB board and other aspects of the miner are also all experienced with their respective tasks. We will be facilitating frequent and strong communications between everyone working on the various components of the miner.
The ultimate answer is that the Sia development team is not qualified to be making this type of hardware. However, the Sia development team is not the team working on the hardware. Most of the heavy lifting is being performed by teams with lots of experience in this industry, including experience that is directly related to cryptocurrency miners.
What we are doing is not new. Dozens of cryptocurrency miners have been created and shipped in the past, and we are not starting from day zero. We have many advantages over the previous rounds of pre-sale cryptocurrency miners, but the biggest is that it's no longer the wild west of hardware design. There is a standard, and there are tried-and-true methods for making reliable cryptocurrency miners. We get to fall back on the mistakes and successes of the many miners that have been built previously, and we will be leaning heavily on teams and people that have direct experience in this field as opposed to doing everything ourselves.

Does this mean that Sia is getting less attention from the developers?

Sia right now has four full time employees. Myself, Zach, Luke, and Johnathan. Zach was hired in June 2017, less than one month ago. He is not a programmer.
Luke and Johnathan will continue with the same responsibilities that they've always had. They helped out a little bit in setting up the website, and in setting up a secure database to process orders + payment information, however the majority of their time has been focused on Sia even as we set up this presale. Going forward, they will be almost entirely uninvolved in Obelisk.
I have had to allocate about 25% of my time to Obelisk. Slightly more this week, due to the PR meltdown we had from the initial announcement. But most of my time is still going towards Sia. Most people know I work over 100 hours per week (some weeks will eclipse 120), and that a quarter of my time is not a small amount.
Zach is closer to 50% Sia, 50% Obelisk at this point. We're expecting that to tone down once the presale is over - much of this time has been spent with banks, with lawyers, with payment processors, and we won't have to do that beyond the initial setup phase. Zach and myself will still be having weekly conversations with every part of the Obelisk supply chain, including the chip designers, chip manufacturers, control board designers, the miner assembly teams, and the fulfillment centers, so even after the presale there will be effort going towards Obelisk.
But nobody on the Sia team is doing chip design, nobody is doing control board design, most of the really heavy work is being done by experienced teams and suppliers that we've found and already spent weeks vetting and verifying. We incorporated Obelisk as a separate company precisely so that Obelisk would eventually have a completely separate team.
And finally, as Obelisk is wholly owned by Nebulous, a successful hardware company does mean revenue and income for the Sia team. Cryptocurrency mining tends to be low margin, so tens of millions in revenue for Obelisk does not necessarily millions in funding for the Sia team. But it is something, and it will give us more time to get the storage platform to the next levels of maturity.

Conclusion

I know that a lot of you are concerned about the miner presale that we are conducting. I hope that this post has helped to alleviate those concerns. I hope it makes sense why we are doing a public presale, instead of seeking private investment until we have a full prototype. I hope this post has clarified our decisions around payment methods, and around our price point. I hope you feel more confident that this is something we will be able to pull off. And finally, I hope I've reassured you guys that Sia is still our primary focus, and that we haven't suddenly pivoted into being a hardware company.
We are ultimately doing this to provide better security to the Sia network. GPU mined coins are frighteningly insecure, and Sia is now large enough where there is serious money on the line. We are doing this to gain security, and also to ensure as much decentralization as possible when it comes to chip manufacture.
We are typically viewed as one of the most reputable teams in cryptocurrency, and I know it's why a lot of you are here. We hope that the Sia ASIC that we are going to be manufacturing and selling strengthens this reputation, but ultimately we will not find out until the miners are actually being shipped.
We continue to be excited about this new product. We truly do feel that ASICs are the right direction for Sia, and we also feel that we are doing the right thing by bringing the opportunity to own a Sia ASIC to the broader Sia community. We are sorry for the fallout from our sloppy original announcement, and we hope that we have since made up for it.
Finally, we hope that you are interested in buying a miner. Even if we only sell a small batch, ASICs are going to utterly dominate the hashrate of Sia going forward. This is an egalitarian sale where everyone has equal opportunity to buy a miner - there's no cap, and we will ensure that small buyers are not shut out by larger buyers in any way.

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.

FrankenSegwit2x and what I'm going to do about it. (Maybe you too)

  1. Setup a bip148 UASF node
  2. Activate my old 60 gh Butterfly labs miner and connect it to some UASF pool.
Now some of you will say that I'm a naive old-white-man for fighting good connected and financed suits plus their petahash powerful miners with a node and an obsolete miner. You are right but I'm going to do it simply because that's what I can do in this fight for Bitcoin's and bitcoin's independence from the suits. The same suits that ran for generations the legacy banking system and which enslaved generations of hard working "nobody s" all over this planet. I'm going to do my part. What are you going to do?

The biggest blemish is a rip in the plastic protective layer over one of the status LCDs on the front of the S4 units.
Asking $1300 for the whole bundle, local cash at pickup or delivery within 50 miles of 60169.

FUCKING SCUM ASS PIECES OF SHIT KnCMiner.com tried to swindle customers out of their Free Neptune with a very dirty trick. Forget the law, these fuckers need a serving of raw street justice.

Guys a week ago, I told you I came across a tip letting us know that the Free Second Neptune might be a scam. It was partly right.
Take a look at this POST warning about second neptune and the fake Hash While you wait.
Here is a histroy of these pieces of shit fucking people over, left and right
Post A
Post B
Post C
A few people messaged me stating that this morning KnCMiner sent out an email with the following content to all of their customers:
Dear Customer,
As you are a Neptune customer, you are entitled to take up our Plan B offer to “Hash While You >Wait”, or to convert your Neptune order to a KnC Titan.
To activate your account please click the following URL/Link where you can choose your option >and setup your KnCCloud account.
Your hashing will begin on Monday the 23rd of June from 9am UTC, provided you’ve made that >choice on the Neptune Order Options.
To ensure you receive all the power you've paid for, please ensure that your account is up to date >with your wallet address to receive your Plan B mined Bitcoins.
Hashing will stop as soon as your unit ships out from our factory.
If you have any questions please contact: [email protected]
Thanks KnC Miner Team
Here was their original statement about Hash While you wait
Hash while you wait.
First it’s important to note that we don’t expect to be late at all everything is on track. It’s just always good to have a backup plan. Second our mega-data centre in the north of Sweden is nearing completion so we can give out some more details. All customers of Neptune’s will be able to use completely free of charge our data centre to hash for them at 3TH either on our pool or a pool of their choice while they wait for their product to be shipped. The first customers (batch 1) are expected to be hashing in our data centre in early June and the last customer will hash in our data centre around the last week of June. All the customers will be able to hash in that data centre for as long as we are late in shipping your Neptune product, this service will be provided on a best effort basis. We have a 24/7 operations teams in place with multiple redundant internet and power connections and we will aim to have as close to 0 down time as possible.
Link to the above Statement
Here is their original statement about the free Neptune
Neptune Two For One Program
It has come to our attention that not everyone has been fully informed on our Neptune Two For One program so we'd like to include information on that topic in this newsletter too:
We understand that the math's involved in ASIC product deployment has to make financial sense in an ever-increasing hash rate race. In order to increase value for KnC customers we are adding one extra Neptune miner to each pre-ordered Neptune in batch one and batch two. These bonus machines will be sourced from our batch three production run which is scheduled to ship in August.
If you're a pre-order Neptune batch one or two customer you don't need to take any extra action to receive these additional miners and we are covering all shipping costs as well. You’ll receive info on when and how those bonus miners will be delivered well before the shipment date.
Link to the about statement
However, after all that, today, in their ToS, they had sneaked in a condition that if a customer accepted their offer of "free" Hash While You Wait, you would give up your free Neptune, and any future request for compensation.
Moreover, the ToS state that the service might never even go online or if it does, no guarantee it work properly.
Large number of customers unknowingly agreed to these condition and as a result, lost their 2 for 1 compensation. This was exactly what KnCMiner wanted to happen
Here are links showing customers catching on to it, and calling KnCMiner out on them:
After their shitty trick was out of their box, they changed the page to state that Free Hash While you wait would cost you your Second Neptune.
These mother fuckers are just scum bags, waiting to fuck over as many Joes as possible.
Guys, you need to get this type of information out there, not only to the Bitcoin Community, but others as well, like Litecoin, Dogecoin. etc.
Please, for the love of justice, do not let these things go unheard.

Turnkey bitcoin mining starter kits - is this a product anyone would be interested in?

I've noticed with BitCoin mining there is a lot of assumptions on background knowledge. The user needs to understand the bitcoin hardware and ecosystem, setup with a pool, in some cases there are software assumptions (understanding Linux, installing dependencies for miners, etc.). I happen to have the background and enjoy all of these pieces but some people may want a gentler introduction.
My current thought is a plug and play bitcoin miner. It would be some preconfigured machine that is guaranteed to have some non-trivial hashrate at date of purchase that the user can plug in and type "run" and be mining. It would also include plenty of instructions and how tos for the user to dive deeper and configure to their hearts content. For an illustrative example, image a raspberry pi running a butterfly labs ASIC miner preconfigured with an on device wallet, preconfigured mining pool, and a wizard or directions to walk them through changing necessary passwords.
With all of that said: is there anyone out there who would want such a product?

I have a few questions regarding bitcoin mining, GPUs, and ASICs. (Reposted from /r/Bitcoin)

Okay, so like a lot of you probably did, I made it to this page about mining. The basic message I took from it is that CPUs << GPUs <<< ASICs. CPUs have been rendered obsolete, GPUs are the current go-to mining hardware, and ASICs are going to dominate the future. However, it's not as simple as it seems. I know a friend who has two top-of-the-line, overclocked AMD graphics cards, running about $450 each. He's made about $300 so far, about $15 per day after the crash. So, he's still very far in the red, with about the best GPU setup you can get.
Supposedly, ASICs are orders of magnitude faster than GPUs and use less power; they're the long-term future of bitcoin mining. Google led me to Butterfly Lab's page, and the profitability calculations had me salivating. However, my research revealed that they've been delaying shipping for over half a year, and nobody has actually recieved one yet. If you ordered one now, you'd get it in several months (excluding the almost-certain delays to come). Avalon is another ASIC manufacturer, and they actually ship; however, the going rate for one of their ASICs is about 77 BTC, which is anywhere from $7000-$10000, and they're currently out of stock.
On top of this, once ASICs hit the market, the total hashrate will skyrocket, as well as the mining difficulty, and profit will decrease dramatically for everyone involved. I was hoping to buy either a high-end GPU or a low-end ASIC (not spending more than a few hundred dollars) and make a couple hundred dollars of profit after a few months. But now it seems that ASICs are a myth (or hideously expensive), GPUs are very expensive, and all miners are soon going to start seeing diminishing returns.
All things considered, it seems that the only way to make a profit mining is to already be mining now, because if you try to pick up some hardware and start now you're never going to make enough money to cover your initial expenses. Is that an accurate analysis or is there still hope for the future of mining? Unless somebody tells me I'm wrong, I'll either try actually buying some bitcoin and hoping for the market to recover or just follow Bitcoin's ups and downs as an outside observer.
TL;DR: Was really interested in making a small-scale profit off of mining, did a fair amount of research on it, now my view is "why bother if you don't already have the hardware since you'll never break even." Confirm/deny?

1st BTC/Altcoin Mining Guide, Feedback Welcome!

When I decided to write this guide, I was throwing cryptocurrencies around like they were nothing. I was foolish in the fact that I disregarded the exchange fees that are attached with the services that those exchanges provided. I'm in by no means a cryptocurrency genius, and I'm still not extremely seasoned at it, but I've learned enough about cryptocurrencies in the past month that I feel confident to pass on the knowledge I have learned and to help those who are overwhelmed on where to start.
So what exactly is a cryptocurrency? According to technopedia (n.d.) a Cryptocurrency is a type of digital currency that is based on cryptography. Cryptocurrency uses cryptography for security, making it difficult to counterfeit. Public and private keys are often used to transfer the currency from one person to another.
When mining cryptocurrencies, one important concept needs to be established, and that's hash rate. Hash rate is simply a unit of measurement of processing power. The more your hash rate is, the more profitable mining becomes.
This guide uses specific sites and software, chosen by myself, as a great springboard into the cryptocurrency world. These sites and software are extremely flexible, easy to use, and integrate very well together. The mining pools I've chosen are multiple currency pools, designed to consolidate a major of the cryptocurrencies together, and instead of using several mining pools, you use three.
These are the things you'll need to get started: MultiMiner
Accounts at Coinotron, The Mining Pool Co., and BitMinter
Accounts at Cryptsy and Coinbase
There are a few different ways to mine for cryptocurrencies, the common of which are using your Central Processing Unit (CPU), Graphics Processing Unit (GPU), and Application Specific Integrated Circuit (ASIC) devices. CPU based mining is not profitable any longer, and will cost you money in the end by increasing electricity costs. GPU based mining is still popular, but losing steam against ASIC based mining. If you choose to use your GPU for mining, AMD/ATI based graphics cards (especially the Radeon HD 79xx series of cards), are the most efficient. If you have an nVidia based graphics card, I'm sorry. You can still mine on nVidia cards, but your hash rates are going to be much slower when compared to their AMD/ATI counterparts. If you chose to use GPU mining, Black Friday or Cyber Monday are you best bets for upgrading your equipment. ASIC based mining is quickly losing value with the changing difficulty on all networks, but it's the most cost effective way to increase your hash rate, and see a positive return on any equipment purchases. If my math is correct, using the methods in this guide, in order for any ASIC device to yield a positive cash flow, you've got to get a device that has at least a 5Gh/s rate (such as the Butterfly Labs Jalapeno).
Now for the fun part, explaining how everything in this well greased machine is going to work. Patience plays a big part in the cryptocurrency world, and when I first started, I had none. I was so eager to see the amount of Bitcoin go up, regardless of how much I was getting penalized in fees from trading. So, that's the first step on your journey. PATIENCE. I CANNOT emphasize this enough. Sometimes, you've just got to hurry up and wait, the effects of waiting things out on the cryptocurrency market WILL PAY OFF.
Step one of this machine is signing up for all three pools (BitMinter, Coinotron, and Mining Pool Co.). This is so that you can actually get server addresses to plug into MultiMiner, after signing up for these services though, you've still got a ways to go.
Step two is sign up for Cryptsy. I chose Cryptsy because of the features they're going to offer at a later time, as well as support for 60 cryptocurrencies (which covers all but one of which we can mine). When your Cryptsy account is setup, you will need to go into the Balances portion of Cryptsy, and find all of the currencies in which you will be mining from the pools. Once Balances are loaded up, you will need to click on the Actions button next to the currency, and click Deposit / Autosell, and then Generate Address. There's a small clipboard near the address it generated, and that will copy the address for pasting in the mining pool websites. You will want to copy, and paste all of them to a text document, along with which currency it belongs to. Not only does this keep you from juggling back and forth trying to figure out things, but it helps for reference and setting up MultiMiner.
Once you have those accounts setup, you'll want to sign up for Coinbase. A WORD OF WARNING FOR THOSE WHO ARE PARANOID... Coinbase will want to link to a bank account, this is mandatory if you want to trade your currencies for cash. If you want to trade currencies, just for the sake of trading, then you can skip Coinbase altogether. You can transfer your Bitcoins from Cryptsy straight into Coinbase, and then sell the Bitcoins from Coinbase, and straight into your designated bank account.
MultiMiner, oh how amazing you are. For every cryptocurrency available in all pools, you will need to add these coins, along with server addresses, log-ins and passwords. To do so, click on the drop down next to the Settings button, and click Coins. From there, click on Add Coin, and choose each coin from a pool. This will list it in the box to the left, and give you the ability to add information on the right. You can add multiple servers as well, in case the current server you're mining on goes down. After all your coins are setup, you'll need to setup your Strategies. Click the drop down next to Settings, and chose Strategies. Check the Enable Strategies check box, choosing Straight Profitability from the drop down, and checking the Strategy every five minutes (that way you're not losing money by mining something that has dropped in price). This aggressive price checking makes it to where you're always on top with whatever you're mining. Also make sure you have Mine the Single Most Profitable Coin selected. Stick with CoinChoose as your price source (under Settings), as CoinWarz charges for there services beyond a certain point. Click Start, and take a vacation.
Reading the charts on Cryptsy can be a little tricky, and scary if you've never saw those types of graphs before. Those graphs are called Candlestick Charts, and are used primarily in the stock market. I won't go in to great detail on this, however, you can find a nice cheat sheet on the subject here.
I hope everyone enjoyed the guide, sorry for being punctual and brief, but there isn't anything too elaborate of complicated about searching for cryptocurrencies. I love mining as a hobby, mining's fun, and if there is any money to be made off of mining from my end, great, if not, I had fun mining.
While compiling a spreadsheet of the minable currencies in this guide, if everything is set up correctly (and assuming servers aren't down), you should be able to mine the following:
And while Mining Pool Co. offers ASICcoin and Unobtainium, ASICcoin isn't supported in MultiMiner, and Unobtanium isn't supported in Cryptsy. I still mine for Unobtanium in hopes that Cryptsy will include it one day.

New Bitcoin Mining Rig Questions

I've been mining on my 6850 for a few months and I've decided that it's pathetic. I understand that "when ASICs arrive" it will change the entire mining ecosystem, but given the perpetual delays in shipping (at least from Butterfly Labs), I want to build my own GPU powered miner. I have about $4k USD to put into a system (or multiple systems if that's a better idea) and I'd like it to hit at least 3.5 Gigahash/s. So here's my questions:
1) To keep the machine viable as long as possible, it needs to be power efficient. The numbers I've seen on the new 7990 put it at about 1.2 Ghash for 375 watts of consumption (https://en.bitcoin.it/wiki/Mining_hardware_comparison and http://www.tomshardware.com/reviews/radeon-hd-7990-review-benchmark,3486.html) - 3.2 Mhash/watt. Would I see better efficiency numbers from a different card?
2) I understand that mining does not require the card to be in a full speed PCIe slot to get optimal hashing power. If I use a 7990, is the fact that it is a Dual-GPU card going to require more than a 1x PCIe slot? Or, more specifically, how much bandwidth does hashing require per Mhash/s? The answer to that question leads to the last question -
3) If I build a setup with a backplane for additional PCIe slots, how many slots could I realistically add before Windows 7 Ultimate x64 fails to recognize the devices or otherwise derps out? I'm not against setting up with a Linux based system, I just haven't seen appropriate drivers available on that platform. (Side note - do I NEED Catalyst drivers to run an OpenCL miner?)
Any advice or information on suggested builds would be appreciated, and I'll tip helpful people. Thanks!

curious about bitcoin mining & hardware

I was curious about what setup I should have to start mining. I've been reading about mining for some time and now I feel i should actually get into it since I have some money to start out with.
I was looking at the 25 GH/s Bitcoin Miner from Butterfly Labs and was also looking at mining contracts and calculators to see if it is even worth buying. I'd love if some of you could fill me in.

[Follow up post] We broke even on our miner in under a month.

Here's the original post.
I kept up with the data points over the course of the month. The data set at the bottom of the post is showing date/time, core temp, dedicated 5200 BTU AC unit on or off, and total mined at that moment. This is the actual, realistic yield in a residential environment of a BFL 500 G/Hash Mini Rig will all the issues, downtime, overheating, stretches of uninterrupted mining, unexplained low hash rates, maintenance, blown 15 amp breakers, etc.
I know the first two things that anyone can say are 1) you should have just bought bitcoin and could have had four times the coin 2) Butterfly Labs sucks. Let's just get those two out of the way.
As far as #1 is concerned, yes, we could have had 3-4 times the bitcoin if we sunk 10 grand USD into BTC instead of this rig. But there's no regrets. We met some awesome people - fellow miners and enthusiasts, got to experiment with some crazy setups and hardware change-ups, got to build actual AC ducting out of thermal barrier, and learn about other SHA cryptos. The interesting and exhilarating internal life is totally worth some of that magic internet money.
The total house electric bill was around $200, which includes running central air and everything else. BFL is a 3kW unit.
As far as #2, BFL kinda does suck. They shipped late, the front tablet was dead on arrival, and forums didn't seem to be responsive at all. Well, it's the wild west still, I suppose.
A few words for those who think about mining.
  1. Anticipate heat and noise. It's like 34 degrees outside right now, and our uninsulated garage is t-shirt comfortable. Imagine what was going on when it was 80 outside.
  2. Have a way to plug into multiple circuits because you may need 220v. Obviously, it depends on what you're buying, but if you're picking up some of these used BFL beasts, don't expect to plug them into a single outlet and call it a day. You may need two separate breaker circuits, which may mean extension cords running through hallways and rigs going dead when the wife turns on the microwave.
  3. Prepare to never break even. Buy rigs with your play money and don't consider them investments. It may happen that many people cash a few coins out, grab some new 2 T/Hash units early next year, and jack up the difficulty into the stratosphere. The era of garage enthusiasts is largely over.
Questions welcome.
