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.

tezos - A self-amending cryptographic ledger

•    OCaml

Tezos is a distributed consensus platform with meta-consensus capability. Tezos not only comes to consensus about the state of its ledger, like Bitcoin or Ethereum. It also attempts to come to consensus about how the protocol and the nodes should adapt and upgrade. The Tezos Alpha (test) network has been live and open since February 2017.

mythril-classic - Mythril Classic: Security analysis tool for Ethereum smart contracts

•    Python

Mythril Classic is an open-source security analysis tool for Ethereum smart contracts. It uses concolic analysis, taint analysis and control flow checking to detect a variety of security vulnerabilities. If you a smart contract developer who wants convenience and comprehensive results, you should be using MythX, our next-gen smart contract security API that integrates with Truffle Framework and other development environments.
