Practical Byzantine Fault Tolerance (PBFT)

A healthcare blockchain must comply with GDPR, which includes the right to erasure. The blockchain stores patient data immutably. What is the best governance approach to reconcile immutability with GDPR?

Store only hashes of patient data on-chain and keep the actual data off-chain in a compliant database.

Encrypt patient data on-chain and discard the encryption key upon erasure request.

Use a private blockchain and delete the data from the ledger when requested.

Avoid storing any patient data on the blockchain and use a centralized database only.
