Abstract:
A blockchain processing method and system for verification of deleted data for blockchains. An item of data is deleted from a block of a blockchain by: identifying the block of the blockchain storing the item of data; deleting the item of data from the identified block without deleting a hash value associated with the deleted item of data from the identified block; and adding metadata to a new block of the blockchain identifying the deleted item of data. The metadata includes a block identifier (ID) of the identified block as a location of the deleted item of data as well as the hash value associated with the deleted item of data. The block ID may comprise a root hash in a block header of the identified block, a universally unique identifier (UUID) allocated to the identified block, or an offset from the new block to the identified block.

Claim (Index 2):
The method of  claim 1 , further comprising hashing the metadata to create a hash value for the metadata, and adding the hash value for the metadata to the new block of the blockchain.
