Getting Started

What is Waltonchain?

The Waltonchain Foundation is building a cross-industry, cross-data sharing platform by integrating Blockchain with the Internet of Things through self-developed RFID Chips with intellectual property rights.
The in-house developed Waltonchain RFID chips integrate a proprietary, genuine random number generator and an asymmetric encryption logic and hardware signature circuit, all of which are patent-protected.
The combination of self-developed RFID chips and the Waltonchain blockchain will ultimately achieve the interconnection of all things and create a genuine, believable, traceable businessmodel with totally shared data and transparent information.
Waltonchain will unfold a new era of the Value Internet of Things (VIoT).

Launch of Waltonchain
 

The Project

The Waltonchain team has formulated a 4-phase development plan, starting from infrastructure platform establishment to gradually incorporating retail, logistics and product manufacturing, and to finally achieving the full coverage of the business ecosystem.
 
As for the phase 1.0 of the project, the team has developed the clothing system integration scheme based on RFID. The application scenarios at phase 1.0 will establish Golden demonstration template
At phase 2.0, our RFID beacon chip will be massproduced and can be used in clothing, B2C retail and logistics.
At phase 3.0, manufacturers will achieve traceable customization of intelligent packaging.
At the project phase 4.0, with the upgrading and iteration of assets information collection hardware and improvement of blockchain data structure, all assets can be registered in Waltonchain in the future.

Agreement with Satoshi – On the Formalization of Nakamoto Consensus

Cryptology ePrint Archive: Report 2018/400
Date: 2018-05-01
Author(s): Nicholas Stifter, Aljosha Judmayer, Philipp Schindler, Alexei Zamyatin, Edgar Weippl

Link to Paper


Abstract
The term Nakamoto consensus is generally used to refer to Bitcoin's novel consensus mechanism, by which agreement on its underlying transaction ledger is reached. It is argued that this agreement protocol represents the core innovation behind Bitcoin, because it promises to facilitate the decentralization of trusted third parties. Specifically, Nakamoto consensus seeks to enable mutually distrusting entities with weak pseudonymous identities to reach eventual agreement while the set of participants may change over time. When the Bitcoin white paper was published in late 2008, it lacked a formal analysis of the protocol and the guarantees it claimed to provide. It would take the scientific community several years before first steps towards such a formalization of the Bitcoin protocol and Nakamoto consensus were presented. However, since then the number of works addressing this topic has grown substantially, providing many new and valuable insights. Herein, we present a coherent picture of advancements towards the formalization of Nakamoto consensus, as well as a contextualization in respect to previous research on the agreement problem and fault tolerant distributed computing. Thereby, we outline how Bitcoin's consensus mechanism sets itself apart from previous approaches and where it can provide new impulses and directions to the scientific community. Understanding the core properties and characteristics of Nakamoto consensus is of key importance, not only for assessing the security and reliability of various blockchain systems that are based on the fundamentals of this scheme, but also for designing future systems that aim to fulfill comparable goals.

Marvel, a $100 VR headset created by a teenage self-proclaimed "Real life Tony Stark", raised $100K last year, but has no updates

So Erik Finman is currently holding the top spot in both IAMA and AMADisasters:
In his IAMA post, he describes how he came to invest in bitcoin, and what he did with the windfall (emphasis mine):
Fast forward to early 2015. Eventually I found a buyer for the companies code & technology in January 2015. The investor offered either $100,000 or 300 bitcoin, which had dropped in value at that time to a little more than $200 a coin. I took the lower cash value bitcoin deal because I believed it was the next big thing and an official buyout would’ve been very difficult for someone under 18 and it was good tax planning to use Bitcoin. Also continuing to do day trading on a daily basis. I used some of that money in the coming years to travel the world. Going to London, Dubai, Australia, and more! I used that to start a VR company using crowdfunding and that did well. I shipped all those out. It was incredible!
Googling around, I found this Indiegogo campaign page for "The Marvel by Finman - The First VR Computer & OS"
https://www.indiegogo.com/projects/the-marvel-by-finman-the-first-vr-computer-os-phone-gadget#/
Work on your slides in Hawaii. Play games on a huge screen. Use as many monitors as you want.
Ignoring Finman's IAMA/bitcoin achievements, and evaluating this Indiegogo campaign on its own merits...it seems to have some warning flags found in other problematic crowdfunding campaigns:
Additional reading:
If you consider what Finman claimed in his IAMA -- "I shipped all those out. It was incredible!" -- then there's more to question. The Indiegogo campaign page, more than a year old now, has 0 updates, so there's no announcements regarding delivery or shipping.
In the past year, only 2 backers made comments, asking questions about the headset that never got answered. The campaign overall has only 79 backers, 71 of which opted for the $99 reward of a headset. The rest of the $100K seems to have come from the 8 backers who paid for the $5,000 package, and the 5 backers who went for the $10,000 package.
