ATS message, on February 13th, Ethereum co-founder Vitalik Buterin posted on social media, stating that the 'Railgun privacy pool mechanism allows Railgun to avoid handling proceeds of crime without any monitoring or backdoors. The operation is as follows: · Anyone can make a deposit to Railgun. · After the deposit, there will be a 1-hour detection period during which various algorithms will analyze whether the deposit may be from criminal activities. · If the deposit passes the screening, the user can use Zero-Knowledge Proof (ZKP) for private withdrawals after 1 hour (but it is recommended to wait longer to obtain a sufficient anonymous set). · If the deposit does not pass the screening, the user can only withdraw the funds back to their Address. This will not result in the funds being frozen or confiscated, only the inability to enjoy the anonymity feature of the privacy pool. If someone disagrees with Railgun's screening rules, they are free to fork and create their own privacy pool, but without sufficient broad public support, their Anonymity will be very limited.
