> Does Solana have the ability to roll back the chain or remove specific pieces of information from it? Well potentially if enough validators forked the chain before the material was added and were able to build a longer chain than the one with the classified material, but even then it would be pointless as the previous chain still exists and will have been distributed to every node. The question is, why would they want to remove it? Solana is a global blockchain, not a US government entity. If they were to abide by US government requests, it would be only fair to also abide by the requests of other governments - but what if North Korea wanted information removed? As you said, where do we draw the line over what is a "valid" request? And more importantly, who draws the line? There is no single Solana entity, it is a group of validators who would decide this. Achieving consensus on something like this would never happen, especially among a group of people who are trying to be resistant to government censorship.
