Previous Solutions and Their Limitations
A first approach to data redaction in blockchains was proposed by Ateniese et al. [7] that mainly tackled the permissioned setting and thus remained ineffective for Bitcoin. In [8], [9], [10] the problem of redacting a permissionless blockchain is solved using consensus protocols. Each of these works presents different voting procedures that users have to perform to decide if a proposed modification can be stored on the blockchain or should be refused.
