Toy implementation of blockchain based on Bitcoin in Rust

What is implemented so far:

1. Mining of genesis block
2. Proof of work based on finding hash that fulfills requirements < 1 << (256b - 24b)
3. Transactions between addresses (strings as of now)
4. Persistance of transactions in the file byte based key value store
5. Generation of real bitcoin addresses
6. Cli

Usage

Install

1. cargo build --release
2. mv target/release/rust-chain .

Commands

1. ./rust-chain --create-blockchain <address to transfer coins from mining genesis block> - creates blockchain and saves db to file
2. ./rust-chain --print - prints to stdout all transactions made in blockchain
3. ./rust-chain --send <address from> <address to> <value> - sends coins from address to another
4. ./rust-chain --balance <address> - check balance on given address
5. ./rust-chain --remove-blocks - removes whole blockchain
6. ./rust-chain --address - generates real unique bitcoin address
