Chainway launches Tornado Cash proof-of-coin service

Developer Chainway has introduced a tool that allows Tornado Cash users to prove their non-involvement with black wallets and fraudsters without disclosing the user's address.

When using the service, the customer specifies which malicious wallets they do not want to be associated with.

The protocol will then check that the user's wallet, from which they made the deposit, is not on the specified list. Merkle trees and zero-knowledge technology are used to check.
