Psy Protocol has launched its public testnet, showcasing a blockchain architecture that combines internet-scale throughput with Bitcoin-level security. The network utilizes client-side zero-knowledge proofs and a horizontally scalable state architecture, achieving million-level transactions per second (TPS) in internal tests. Its innovative PoW 2.0 consensus mechanism transforms mining into the generation and aggregation of zero-knowledge proofs, directly securing transactions. This smart contract platform, based on useful proof-of-work, allows developers to build large-scale Web 3 applications. By generating transaction proofs and aggregating zero-knowledge proofs on-chain, Psy Protocol aims to support the development of robust decentralized applications with high-speed performance and enhanced security.
