Execution Layer

The execution layer entails executing transactions that update the state correctly.

zkLink Nova utilizes zkEVM (zero-knowledge Ethereum Virtual Machine) of ZK Stack to execute smart contracts and proves the correctness of execution using zero-knowledge. Like the EVM, a zkEVM transitions between states after computation is performed on transactions. The difference is that the zkEVM also creates zero-knowledge proofs to verify the correctness of every step in the program’s execution.

zkEVM allows zkLink Nova to be compatible with existing Ethereum infrastructure. Nova provides an easy way for builders to fork various applications that are already deployed on Ethereum and Layer 2 rollups, thereby laying the foundations for a faster-growing ecosystem.
