Moving from Sidechains to Parachains
summary
ChainSafe describes concrete work: a TypeScript beacon client Lodestar, a Go Polkadot runtime Gossamer, a Go cross-chain tool chain bridge and a cross‑client PoA net Gurley testnet. Projects include a Toronto local blockchain with 300,000 users, 150 stores and over $1M spent, plus an interoperable attestation fork that added an EVM opcode. Lessons state modular consensus and substrate‑style parachains remove repeated forks; bridges above the chain proved brittle while small UX fixes (control‑S in Remix) are the only upstream win.
