unchained - My personal study of blockchain related technology.

  •    Makefile

The most recent talk is "Blockchain Jumpstart". It contains a lot of details on bitcoin, ethereum, etc. and I'll keep update it as I study more and more blockchain related technology. Please submit issue if you found anything is wrong or you have any comments upon my thoughts.

The UTXO-based blockchain system (e.g. Bitcoin) and account-based blockchain system (e.g. Ethereum ) opened the door of a brand-new world for us. Despite facing some drawbacks along the way, the impressive success of Bitcoin and Ethereum has certainly proven the value of the blockchain technology and its massive potential in the future. Since 2015, there has been quite a few highly-promising distributed ledger systems which are not block-based blockchain technology turned up, such as DAG (Directed Acyclic Graph). With no doubt, a decentralized digital world is dawning and Bitcoin or Ethereum has the potential to become the fundamental currency in block-based blockchain system. IOTA or Byteball, on the other hand may fulfil a similar role in a system based upon DAG. Although all blockchain issued tokens can be traded on some exchange platform, they can only circulate within their own blockchain systems. We want to create a new decentralized platform, which will be the connecting point of the major blockchain systems, regardless the block-based or blockless-based blockchain system, hence allowing value and information circulate smoothly within different blockchain system. We call it “HyperCash” or Hcash in short. The Hcash is being developed by cryptography labs in one of the China’s most prestigious university as well as other famous universities in Australia. We will periodically update you with the progress on this over time, and we expected the first hardfork upgrade will happen soon at early Sept 2017. Thanks for your attention and stay tuned for the further update from Hcash dev team.

burrow - Hyperledger Burrow

  •    Go

Hyperledger Burrow is a permissioned Ethereum smart-contract blockchain node. It executes Ethereum EVM smart contract code (usually written in Solidity) on a permissioned virtual machine. Burrow provides transaction finality and high transaction throughput on a proof-of-stake Tendermint consensus engine. Project information generally updated on a quarterly basis can be found on the Hyperledger Burrow Wiki.

hyperledger - Hyperledger Project is a new Collaborative Project at The Linux Foundation

  •    

Hyperledger is an open source collaborative effort created to advance cross-industry blockchain technologies. It is a global collaboration including leaders in finance, banking, Internet of Things, supply chains, manufacturing and Technology. The Linux Foundation hosts Hyperledger under the foundation. Not since the Web itself has a technology promised broader and more fundamental revolution than blockchain technology. A blockchain is a peer-to-peer distributed ledger forged by consensus, combined with a system for “smart contracts” and other assistive technologies. Together these can be used to build a new generation of transactional applications that establishes trust, accountability and transparency at their core, while streamlining business processes and legal constraints. Think of it as an operating system for marketplaces, data-sharing networks, micro-currencies, and decentralized digital communities. It has the potential to vastly reduce the cost and complexity of getting things done in the real world. Only an Open Source, collaborative software development approach can ensure the transparency, longevity, interoperability and support required to bring blockchain technologies forward to mainstream commercial adoption. That is what Hyperledger is about – communities of software developers building blockchain frameworks and platforms.


ethereumbook - Mastering Ethereum, by Andreas M. Antonopoulos, Gavin Wood

  •    Javascript

Mastering Ethereum is a book for developers, offering a guide to the operation and use of the Ethereum, Ethereum Classic, RootStock (RSK) and other compatible EVM-based open blockchains. This repository contains the draft of the book, currently in progress, scheduled for publication in Q4'2018 by O'Reilly Media. The publication date has been delayed, unfortunately, due to some personal issues. Expect to see content developed and pushed here in Q1 and Q2 2018.

zkproofs - Zero-Knowledge Proofs

  •    C

One fundamental concern in blockchain technology is the confidentiality of the data. In order to reach consensus between all independent nodes, each node must be able to validate all transactions (for instance against double-spend), in most cases this means that the content of the transactions is visible to all nodes. Fortunately, several solutions exist that preserve confidentiality on a blockchain (private transactions, HyperLedger Fabric Channels, Payment Channels, Homomorphic encryption, transaction-mixing, zero knowledge proofs etc.). The Zero Knowledge Range Proof requires a commitment on a number by a trusted party (for instance a government committing on someone's age), an Ethereum user can use this commitment to generate a range proof. The Ethereum network will verify this proof.

exonum - Exonum core repository

  •    Rust

Exonum is an extensible open-source framework for creating blockchain applications. Exonum can be used to create cryptographically powered distributed ledgers in virtually any problem domain, including FinTech, GovTech, and LegalTech. The Exonum framework is oriented towards creating permissioned blockchains, that is, blockchains with the known set of blockchain infrastructure providers. See individual projects' readme for the details.

Waves - Blockchain platform

  •    Scala

Waves is an open-source blockchain platform, that allows users to launch their own custom cryptocurrency tokens. Whilst popular cryptocurrencies such as Bitcoin and Ethereum can be traded on external exchanges, and Ethereum allows users to create new tokens on the platform using a smart contract, Waves includes this functionality in its core software and wallet. Users can create, transfer and exchange blockchain tokens on a peer-to-peer basis, paying transaction fees in the native WAVES token.

Welcome! This is a Python-based Dash app meant to track whale activity in buy / sell walls on crypto-currency exchanges (presently just operational for GDAX, but more exchanges to come). This document aims to explain the purpose, functionality, and future of this project. Please do share this with your fellow coders / traders / crypto-aficionados, donate via the donation addresses included in the "Support Needed" section below, and contribute to the future of this project by calling out issues, requesting new features, and submitting pull requests to improve the app. If you want to use a hosted version of the app, check out this link here which has been graciously hosted by a member of the Ethereum community while we raise money via donations to migrate to AWS. If for any reason the page does not load properly, feel free to let us know via an issue, but more than likely it is because we are updating to the newest version of the codebase or performing maintenance.

naivechain - A blockchain implementation in 200 lines of code

  •    Javascript

All the current implementations of blockchains are tightly coupled with the larger context and problems they (e.g. Bitcoin or Ethereum) are trying to solve. This makes understanding blockchains a necessarily harder task, than it must be. Especially source-code-wisely. This project is an attempt to provide as concise and simple implementation of a blockchain as possible. From Wikipedia : Blockchain is a distributed database that maintains a continuously-growing list of records called blocks secured from tampering and revision.

Ethereum is gaining a significant popularity in the blockchain community, mainly due to fact that it is design in a way that enables developers to write decentralized applications (Dapps) and smart-contract using blockchain technology. Ethereum blockchain is a consensus-based globally executed virtual machine, also referred as Ethereum Virtual Machine (EVM) by implemented its own micro-kernel supporting a handful number of instructions, its own stack, memory and storage. This enables the radical new concept of distributed applications.
