Append-only structures such as blockchain, never forget their past. Once user data gets into a block, it stays there forever. The right to be forgotten seems to be in conflict with this nature, and at first glance, erasure of user data and blockchains, cannot coexist. We present how GDPR compliance can be easily and simply incorporated into Hyperledger Fabric in a native manner, which grants users with the right to be forgotten. Our design draws from Hyperledger Fabric's unique architecture, and modifies the block structure in a backward compatible manner, eliminating user data from the blockchain without sacrificing correctness or consistency . We evaluated our solution and found that it provides GDPR compliance with only a minimal performance overhead, making it a viable solution for Hyperledger Fabric or any other execute-order-validate type blockchain.
