Historic data


#1

Curious about “blockchains do not allow modification of historic data…” What do you think how big problem it would be for us? In our cases we would have trend break, and new chain would need to be used right? Would new chain hold information about past transactions or?

The new chain would at a minimum contain a snapshot of the previous chain’s data. Please see this paper for a description of how a chain migration would happen.
