#KEY KeyChain is the world's first public chain protocol centered on 'full-dimensional intelligence', deeply integrating layered heterogeneous architecture, quantum-resistant security, zero-latency cross-chain interoperability protocol, and environment-adaptive consensus mechanism. It aims to break through the 'impossible triangle' of blockchain, building a high-performance underlying infrastructure that supports tens of thousands of TPS, millisecond-level confirmations, and zero-friction cross-ecological collaboration in the Web 3.0 era.
