Prunable data can be removed from the blockchain without affecting the integrity of the blockchain. When a transaction containing prunable data is created, only the 32-byte sha256 hash of the prunable data is included in the transactionBytes, not the prunable data itself. The non-prunable signed transactionBytes are used to verify the signature and to generate the transaction's fullHash and ID; when the prunable part of the transaction is removed at a later time, none of these operations are affected.
