Zero-knowledge Merge refers to a process in blockchain technology where two different blockchain states can be combined without revealing any sensitive information about the data contained within them. This concept leverages zero-knowledge proofs, enabling one party to prove to another that a statement is true without disclosing any information beyond the validity of that statement.In practical terms, when two chains undergo a merge using this method, participants or nodes involved can confirm that the merge is valid without needing to see the underlying data or transactions. This enhances privacy, ensuring that user details and transaction specifics remain confidential.The approach compares favorably to traditional methods where full transparency is required, which can expose sensitive information. By maintaining the core functionality of a blockchain while protecting individual privacy, Zero-knowledge Merge aims to facilitate better collaboration and integration between different blockchain networks, all while keeping user data secure.
