Rather than simply being Layer 2 for Bitcoin, Arch Network is dedicated to bringing programmability directly on top of Bitcoin, enhancing Bitcoin's native programmability with a parallelized PoS network and ZK proofs, building a decentralized network of verifiers that enables programmability, parallelized execution speeds, and trust-less interoperability and composability.
