Introducing SatoshiVM: Pioneering the Future of Smart Contract Execution
SatoshiVM is a decentralized, Bitcoin-based ZK Rollup Layer 2 solution, seamlessly integrating with the Ethereum Virtual Machine (EVM) ecosystem, and leveraging native BTC as gas. By bridging the EVM ecosystem with Bitcoin, SatoshiVM empowers the Bitcoin ecosystem to issue assets and develop innovative applications.
We have refined a method that enables the verification of arbitrary function execution on Bitcoin, rendering it more suitable for Layer 2 block validation. The Verification System of SatoshiVM is a robust system designed to ensure the precise execution of Layer 2 blocks on Bitcoin, without necessitating any modifications to the Bitcoin protocol itself. This innovative system is capable of confirming the correct execution of a series of Layer 2 blocks on Bitcoin, leveraging the existing infrastructure. Consequently, Bitcoin can effectively serve as a settlement layer for Layer 2, thereby bolstering the security of Bitcoin Layer 2 transactions.
The system harnesses the capabilities of Taproot, which facilitates the representation of complex function execution through a single, succinct hash. By fully executing the zero-knowledge proof process off-chain for a block and verifying the proof on Bitcoin via Taproot, the system ensures the validation of blocks with utmost efficiency. Furthermore, when the block miner on Layer2 submits each block validation transaction, they concurrently submit the hash of the corresponding block data and proof data to Bitcoin. Consequently, anyone can utilize the submitted hash to retrieve comprehensive data from a specific DA layer, thereby enabling third-party verification of Layer2 blocks with ease.
