Our Scenario and Results
In our work we envision a scenario in which a Bitcoin node storing the full blockchain wants to delete some data encoded either in the coinbase or in a data output transaction. Our approach completely deviates from previous ones in that it relies on individual redaction rather than on jointly decided redaction. Each individual redaction will not be replicated by the Bitcoin network. Indeed, our solution permits a scenario in which a set of nodes can delete some content due to imposition by an authority whereas other nodes can still keep such content. We remark that our solution guarantees that the Bitcoin financial state (i.e., the UTXO database) remains unchanged.
