zkEVM

During the past two years, it has become more clear that zkEVM will be the dominant scaling solution on Ethereum and even other public chains: with this in mind, currently, some very prominent teams have been making great progress to achieve this, such as PSE, zkSync and Polygon Hermez.

Basically, zkEVM provides the same virtual machine environment as EVM and can generate valid zk proofs of its output. With zk, blockchain-interaction costs can be reduced significantly, especially the transaction cost. So far, more than 50% of transactions on Ethereum are transfers, most of which are deposits and withdrawals from exchanges.

For every batch of transactions, a zkSNARK cryptographic proof will be generated off-chain.

This zkSNARK proves the validity of every transaction in a batch which means it is not necessary to re-execute on Ethereum or Fantom to verify each signature transaction.

The significance of this is that it allows verification to be carried out in constant time regardless of the number of transactions. This ability to verify proofs both efficiently and in constant time is at the heart of all infinite computation schemes.

Therefore, we can utilize ZKEVM to enable the majority of clients to complete block validation within a fixed and minimal amount of time. This undoubtedly significantly enhances the processing capacity of the clients.
