ZKTube is a two-layer protocol that uses Zero-knowledge proof and ZK rollup to achieve low transaction costs and high throughput transactions between ETH and erc20.ZKTube is a project built and developed on Layer2 using the PLONK protocol based on ZK roll up technology. It can improve scalability by converting batch transfers into a single transaction. Its essence is to compress and store the user state on the chain in the Merkle tree and transfer the user state change to the chain while ensuring the correctness of the user state change process under the chain through the Zero-knowledge proof mechanism. The cost of directly processing user state changes on the chain is relatively high, but it is relatively low to verify the correctness of Zero-knowledge proof PROOF using only the smart contract on the chain. In addition, the required remittance information is transmitted to the contract along with the voucher, making it convenient for users to verify their accounts....
