Mine Blockchain
summary
A minimal blockchain implemented in Node.js using an HTTP server and WebSocket peers that sync chains, accept new data, perform basic proof-of-work mining and block validation, and shows mining from multiple clients. The demo’s mining and hashing take about 17 seconds per block (making lightweight interactions like “likes” impractically slow) and yields only a few dollars per period; for production the recommended approach is to put logic in smart contracts (Ethereum) and store only hashes on-chain while keeping full data off-chain.
