ediscoin

A proof-of-work cryptocurrency based on lhartikk's naivecoin, written in Rust.

Overview

ediscoin is a simple SHA256, proof-of-work cryptocurrency. It does basic network syncing between nodes (based on Nakamoto consensus) over HTTP, dynamically adjusts difficulty, and exposes an HTTP interface to the client.

Getting started

cargo run starts a node on localhost:8080 by default, or you can pass a port as an argument: cargo run -- 8000. Each node exposes an HTTP interface with the following routes available:

Control routes

• GET /blocks: Returns a JSON payload with the current blockchain
• GET /latest-block: Returns a JSON payload with the latest block
• POST /mine: Attempts to mine the next block, returning it if successful and returning the latest block if not

P2P routes

• GET /peers: Returns a list of peers
• POST /add-peer: Takes a single address string as a body and adds it to the peerlist. Currently there is no automatic peer discovery, so peers must be added manually.
• POST /update-chain: Takes a JSON array of blocks and updates the node with those blocks if they're valid and longer than the node's current chain
