The Future of Sidechains
summary
Paper first appears in 2014 and a miner-pegged BIP-300 drivechain is prototyped on testnet (clones of Zcash, Ethereum, NFTs and even a joke “trainchain”), while a live production option exists as the Liquid federation that uses HSMs and multi-signers. Claim: sidechains give Bitcoin modular extensibility without new coins. Trade-offs documented: miner-controlled peg and potential theft, federation trust, or heavy zk-SNARK costs and verification overhead. Activation stalls—opcodes or Simplicity remain the likely paths and real-world deployment timelines can span five to six years.
