One of the biggest features of blockchain is that it cannot be tampered with; all content will be preserved. However, this may itself be a false proposition. Decentralized servers are still centralized, and in reality, there are too few that can run full nodes. The consensus mechanisms are also uneven, and it is even possible that if AWS suddenly goes offline, some public chains will become inaccessible.

Decentralization and immutability are currently just an illusion of consensus under ideal conditions. Once the majority of nodes or validators are controlled, the data on the chain can be legally altered or rolled back.

Imagination is beautiful, expectations are also beautiful, but reality is still harsh. At least, that is the case at present.
