A collection about awesome blockchains - open distributed public databases w/ crypto hashes incl. git ;-). Blockchains are the new tulips 🌷🌷🌷. Distributed is the new centralized.

blockchain (crypto) tools, libraries & scripts in ruby

🚀 DISCoHAsH - Simple, fast, quality hash in 120 lines. 10GB/s serial (depending on hardware). Also in NodeJS

The fastest 128-bit and 256-bit hash, passes all tests, and under 140 source lines of code. API library and CLI tool in C++ and NodeJS/Wasm

A collection of Kotlin Multiplatform cryptographic hashing functions.

💎 Beamsplitter - A new (possibly universal) hash that passes SMHasher. Built mainly with a random 10x64 S-box. Also in NodeJS

Best of Crypto Books - A collection of books, white papers & more about crypto and blockchains.

🐤 floppsy - SMHasher-passing 200Mb/s hash using floating-point ops

The BLOCKSET application is a command line program that can store and retrieve data blocks using a content-dependent tree (CDT) hash function as a universal address of the blocks.

A pure managed C# implementation of well-known cryptographic hash functions such as SHA-family (SHA0, SHA1, SHA2, SHA3), MD-family (MD2, MD4, MD5), RIPEMD, Tiger, Haval, Snefru.

Cryptographic message digest algorithms as a Java library with standard JCA adapters

The WHIRLPOOL hash function implemented in Swift.

Create and compare hashes of .exe and .dll files in order to detect updates

Custom Blockchain: A simple custom blockchain implementation that demonstrates the fundamental concepts of blockchain technology. This project includes core blockchain functionalities such as block creation, chain validation, and proof of work, providing a basic framework for understanding how blockchains operate.
