This function seriously violates the fundamental characteristic of blockchain - immutability. In specific situations, such as hacker attacks or other problems, the blockchain community might consider using the state rollback function to recover losses. However, this operation is highly controversial because it violates the core principles of blockchain. It is worth noting that the conditions for rolling back blockchain data are very strict, and the likelihood  of success in real operations is small. Therefore, when encountering claims that can recover virtual currencies through blockchain rollback, it is necessary to be cautious and verify the authenticity of such claims."}]}],"pr":"18e95045fd62f819d4c5a35e3ab3a64767c4909d23593f2ec797d48938c47ddf"}
