Let's create a blockchain with PHP!
summary
A PHP implementation builds a tiny cryptocurrency: a peer-to-peer gossip protocol shares full state, public/private keys sign transactions, and blocks use a nonce-based proof-of-work so hashes start with N zeros (three zeros takes ~500 iterations in the demo). Nodes eventually converge, transfers propagate and overspend attempts are rejected, forks resolve by choosing the longest chain, and the demo works end-to-end. Limitations include mining centralization via pools, slow confirmations (recommend six blocks) and rising fees; Lightning Network is noted as a possible fix.
