Key Public Chain, also known as KeyChain, is the world's first public chain protocol centered around 'multidimensional intelligence'. Below is a specific introduction:

- Core Technology: Integrates layered heterogeneous architecture, quantum-resistant security technology, zero-latency cross-chain interoperability protocol, and environment-adaptive consensus mechanism. It employs quantum gravity consensus, achieving a throughput of 1,000,000 TPS, resistant to 51% attacks and Sybil attacks, as well as technologies like hyper-dimensional sharding, zero-knowledge interoperability protocols, and self-evolving smart contracts.

- Performance Advantages: Aims to break through the blockchain 'impossible triangle', providing high-performance underlying support for the Web 3.0 era with tens of thousands of TPS and millisecond-level confirmations, enabling frictionless cross-ecosystem collaboration.

- Issuance Situation: The total issuance is 97 million, committed to creating a deflationary value public chain system. Global registration and promotional mining will start on June 1, 2025, at 20:00, with free basic coins and basic computing power for registration, and promoting friend registrations can accelerate mining.

- Team Background: The core members consist of technical backbones from well-known projects such as Ethereum, EOS, LINK, and also include engineers and executives from multinational companies like META and Microsoft.

- Application Scenarios: The application scenarios are extensive, covering multi-chain collaborative ecosystems, high-frequency trading, enterprise-level applications, RWA (real-world asset) underlying protocols, decentralized exchanges, and more.

- Project Progress: The Key project has obtained a license from the Colorado state foundation in the United States and is about to release a U.S. MSB license, aiming to build a blockchain infrastructure that seamlessly connects the real and digital worlds, self-evolving, and infinitely scalable.
