Open Source Rust Cryptocurrency Software

Solana is the fastest blockchain in the world and the fastest-growing ecosystem in crypto, with thousands of projects spanning DeFi, NFTs, Web3 and more. Integrate once and never worry about scaling again. Solana ensures composability between ecosystem projects by maintaining a single global state as the network scales. Never deal with fragmented Layer 2 systems or sharded chains. Solana's scalability ensures transactions remain less than $0.01 for both developers and users. Solana is all about speed, with 400 millisecond block times. And as hardware gets faster, so does the network. Not only is Solana ultra-fast and low cost, but it is also censorship-resistant. This means the network will remain open for applications to run freely and transactions will never be stopped. Help secure the network by running decentralized infrastructure. Learn about operating a validator node. See the get started guide, videos, tutorials, SDKs, reference implementations, and more.

Grin is an in-progress implementation of the Mimblewimble protocol. Grin is a privacy-preserving digital currency built openly by developers and distributed all over the world. Grin has no amounts and no addresses. Transactions can be trivially aggregated. To hide the origin of a newly created transaction, it gets relayed among a sub-set of peers before it is widely broadcasted. Electronic transactions for all. Without censorship or restrictions. Designed for the decades to come, not just for tomorrow. To be used by anyone, anywhere. Grin is not controlled by any company, foundation, or individual. The coin distribution is designed to be as fair as possible, with emission of 1 GRIN per second. Mimblewimble leverages cryptography to allow past transaction data to be removed with no compromise on security. This avoids Grin collapsing under the weight of data having to be kept on-chain.

The Fastest and most Advanced Ethereum Client. Built for mission-critical use: Miners, service providers, and exchanges need fast synchronization and maximum uptime. Parity Ethereum provides the core infrastructure essential for speedy and reliable services. Parity Ethereum's goal is to be the fastest, lightest, and most secure Ethereum client. We are developing Parity Ethereum using the sophisticated and cutting-edge Rust programming language. Parity Ethereum is licensed under the GPLv3 and can be used for all your Ethereum needs. By default, Parity Ethereum runs a JSON-RPC HTTP server on port :8545 and a Web-Sockets server on port :8546. This is fully configurable and supports a number of APIs. If you run into problems while using Parity Ethereum, check out the wiki for documentation, feel free to file an issue in this repository, or hop on our Gitter or Riot chat room to ask a question. We are glad to help!

Ordinal theory concerns itself with satoshis, giving them individual identities and allowing them to be tracked, transferred, and imbued with meaning. Satoshis, not bitcoin, are the atomic, native currency of the Bitcoin network. One bitcoin can be sub-divided into 100,000,000 satoshis, but no further. Ordinal theory does not require a sidechain or token aside from Bitcoin, and can be used without any changes to the Bitcoin network. It works right now. ord is an index, block explorer, and command-line wallet. It is experimental software with no warranty. Ordinal theory imbues satoshis with numismatic value, allowing them to be collected and traded as curios. Ordinal numbers are serial numbers for satoshis, assigned in the order in which they are mined, and preserved across transactions. ord relies on Bitcoin Core for private key management and transaction signing.

Rust-Lightning is a Bitcoin Lightning library written in Rust. The main crate, lightning, does not handle networking, persistence, or any other I/O. Thus, it is runtime-agnostic, but users must implement basic networking logic, chain interactions, and disk storage. The project implements all of the BOLT specifications in the 1.0 spec. The implementation has pretty good test coverage that is expected to continue to improve. It is also anticipated that as developers begin using the API, the lessons from that will result in changes to the API, so any developer using this API at this stage should be prepared to embrace that. LDK/Rust-Lightning is a generic library which allows you to build a lightning node without needing to worry about getting all of the lightning state machine, routing, and on-chain punishment code (and other chain interactions) exactly correct. Note that Rust-Lightning isn't, in itself, a node.
