Abstract

Disclosed is a method and system for modifying content stored in a blockchain. The method comprises identifying an old block of the blockchain comprising undesired data in a transaction of the old block. An updated block may be created by correcting the transaction of the old block. A new block hash may be determined for the updated block. Corrected form of the transaction may be submitted, as a new transaction, along with the new block hash and the difference between the new block hash and hash of the old block. Miners may be allowed to mine the corrected form of the transaction, along with other new transactions. The other new transactions may be mined, based on a consensus of users of the blockchain, into a new block connected to a tip of the blockchain, and the old block may be edited to introduce the corrected form of the transaction.
