Although the Lightning Network [2] inherits Bitcoin's network security and offers partial scalability solutions, it still falls short in supporting smart contracts and further enhancing scalability. We propose a five-layer architecture for Super Bitcoin using the Bitcoin network as the kernel layer, maintaining system security and transaction irreversibility through the proof-of-work (PoW) consensus mechanism; building an efficient communication layer based on the Lightning Network, facilitating rapid transmission of asset information while preserving Bitcoin's decentralized nature; we introduce the Taproot Consensus as the extension layer, abstracting Lightning Network communication and asset information to provide a standardized interface for the upper virtual machine layer; a multi-chain layer, also known as the fusion layer, consists of multiple lightning chains secured by BTC consensus, integrating any mainstream virtual machine (VM) to achieve a "Multi-chain interconnection“ and ”multi-chain interoperability” unified by BTC consensus; finally, at the application layer, providing developers with rich tools and interfaces to build a decentralized application (DApp) ecosystem, all sharing the security of BTC consensus.
