Naive Blockchain
Simple p2p blockchain implementation in Rust with FloodSub (so, no real consensus algo. Simplified.).
Just a bit of educational programming for myself in Rust and with blockchain to understand the concepts.
3 Commands:
- ls p - prints p2p peers connected
- ls c - prints the blockchain to point
- create b - mines a block on the node to set difficulty level
Usage
Use tmux or separate terminals on your machine.
RUST_LOG=info cargo run in each pane or terminal
It'll print INFO messages to screen. You can use commands then as the terminal will also take input for the 3 commands above.
use create b HODL_to_the_Moon_FTW! or similar start to kick off mining a block in each node. They'll mine blocks, flood to each other and add to their chain.
TODOs
- [] TODO Implement better conensus algorithm for block completion and contention
- [] TODO Make the mining automated
- [] Ramp up difficulty level to represent controlled inflation as chain gets longer
- [] TODO Quiet the INFO print out matches to drop unhandled but know messages
- [] Reimplement in Golang to check ease and performance if each (GC etc.)
- [] In particular, implement without Rust's p2plib crate which does all heavy lifting here (Golang version?)
