This repository contains Solidity and Python implementations of several cryptographic primitives, they are designed to work together and make it easier to build novel cryptosystems using composable primitives. These implementations can be easily switched to either the secp256k1 or alt_bn128 curves.

solidity solidity-contracts solidity-compiler ethereum lists resources awesome-list awesomeRemix Project is a platform for development tools that use a plugin architecture. It encompasses sub-projects including Remix Plugin Engine, Remix Libraries, and of course Remix IDE. Remix IDE is an open source web and desktop application. It fosters a fast development cycle and has a rich set of plugins with intuitive GUIs. Remix is used for the entire journey of contract development with Solidity language in as well as being a playground for learning and teaching Ethereum.

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.

It was influenced by C++, Python and JavaScript and is designed to target the Ethereum Virtual Machine (EVM). It is statically typed, supports inheritance, libraries and complex user-defined types among other features. With Solidity you can create contracts for uses such as voting, crowdfunding, blind auctions, and multi-signature wallets.
ethereum smart-contracts programming-language blockchain contracts tokenThis is an easy-to-use implementation of ECDSA cryptography (Elliptic Curve Digital Signature Algorithm), implemented purely in Python, released under the MIT license. With this library, you can quickly create keypairs (signing key and verifying key), sign messages, and verify the signatures. The keys and signatures are very short, making them easy to handle and incorporate into other protocols. This library provides key generation, signing, and verifying, for five popular NIST "Suite B" GF(p) curves, with key lengths of 192, 224, 256, 384, and 521 bits. The "short names" for these curves, as known by the OpenSSL tool (openssl ecparam -list_curves), are: prime192v1, secp224r1, prime256v1, secp384r1, and secp521r1. It also includes the 256-bit curve used by Bitcoin, whose short name is secp256k1. No other curves are included, but it would not be too hard to add more.

Bulletproofs are short zero-knowledge arguments of knowledge that do not require a trusted setup. Argument systems are proof systems with computational soundness. Bulletproofs are suitable for proving statements on committed values, such as range proofs, verifiable suffles, arithmetic circuits, etc. They rely on the discrete logarithmic assumption and are made non-interactive using the Fiat-Shamir heuristic.

Zero Knowledge applications offer meaningful privacy assurance to end users because the servers running the application cannot read the data created and stored by the application.
cloud secure-cloud cryptography securityNaCl (pronounced "salt") is a new easy-to-use high-speed software library for network communication, encryption, decryption, signatures, etc. NaCl's goal is to provide all of the core operations needed to build higher-level cryptographic tools. Of course, other libraries already exist for these core operations. NaCl advances the state of the art by improving security, by improving usability, and by improving speed. Sodium is a portable, cross-compilable, installable, packageable fork of NaCl (based on the latest released upstream version nacl-20110221), with a compatible API.

This allows you to work with the Ethereum blockchain, without the additional overhead of having to write your own integration code for the platform.

It was originally released as part of my DEFCON talk about cracking brainwallets (slides, video, why). The name is a reference to Mind Flayers, a race of monsters from the Dungeons & Dragons role-playing game. They eat brains, psionically enslave people and look like lovecraftian horrors.

Based on Bitcoin's code, it intends to offer a far higher standard of privacy through a sophisticated zero-knowledge proving scheme that preserves confidentiality of transaction metadata. Bitcoin and most cryptocurrencies expose your entire payment history to the public. Zcash is the first open, permissionless cryptocurrency that can fully protect the privacy of transactions using zero-knowledge cryptography.
