Description：Hemi is a modular layer two protocol based on the dual-core powered by Bitcoin and Ethereum, designed for breakthrough capacity expansion, security reinforcement and cross-chain interoperability. Different from the current industry situation where the two major ecology are separated and opposed, Hemi innovatively restructures Bitcoin and Ethereum into super network components with a unified architecture, and releases innovative dimensions of programmability, portability and ecological potential through the smart contract abstraction layer. The protocol is committed to building a converged infrastructure for complex Bitcoin DeFi scenarios, pioneering the in-depth integration of blockchain expansion solutions and AI-enhanced Web3 protocol, laying the underlying architectural foundation for the upcoming smart contract Internet outbreak.
