Mixing service

A mixing service, also referred to as a cryptocurrency tumbler, is a service that mixes identifiable tokens with others. The purpose for this is to obscure the tracing back to the original address. Most mixing services lets users deposit from one address and then withdraw the funds from multiple other addresses. To secure the other end, the mixing service gives the user a private key beforehand which will be entered to access the funds now in multiple addresses. A very popular mixing service on the Ethereum blockchain is Tornado Cash.
