Mini BlockChakin Layer 1 Project

Project Overview

• Layer 1 Blockchain implemented in Rust
• Account-based blockchain
• Five main components: (Network, Consensus (BlockImporter + Miner), PayloadBuilder, Pool (TxPool + Validator), Provider (StateProvider + DB)) + RPC Server
• Consensus Rule: Proof of Work (PoW)
• Difficulty adjustment: doubled or halved every block
• Fork Choice: Longest Chain Rule
• P2P Discovery: initially boot node, if full then random peer from boot node
• World module that describes the game field (not yet implemented)
• RPC: HTTP Server–Client communication
• Heavily inspired by reth
• ECDSA + Signer Recovery (same as ethereum)

How to use

Run a node

cargo run -- --boot-node
cargo run -- --name A --port 30304 --rpc-port 8546 --miner-address 0534501c34f5a0f3fa43dc5d78e619be7edfa21a

Rpc connectioin

Use clients/rpc crate. Currently only responds with binary data (example included).

Execution examples

Boot_node: node start Boot_node: connection with normal node a

Normal node a: node start + p2p connection with boot_node + syncronizing with boot node

TODO LIST

1. Implement World (Whatever! maybe game?)
2. Block Explorer
