The four types of zkEVM are as follows:Type 1: Consensus-level equivalence - This type of zkEVM is completely equivalent to Ethereum at the consensus level. The zkEVM chain state and transactions are identical to those of Ethereum. It can be directly used with Ethereum execution clients and can be introduced onto the Ethereum mainnet. However, the ZKP efficiency is poor and requires a large amount of computation to verify.Type 2: Bytecode-level equivalence - Type 2 zkEVM is completely equival...
