The Data Scientist shall be aware of the implications of new decentralized data storage technologies where critical privacy protecting operations (such as physical record deletion), are not directly supported.
Blockchains are immutable by design. There are no CRUD operations, because there is no updates of a single node or deletions. Some of the GDPR fundamental rights are therefore not supported, such as the right to be forgotten. Several blockchain based storage solutions implement ways of simulating this deletion (e.g.: Bigchaindb uses the term “burn” to refer to the throwing away of the encryption keys or stopping the transferability by generating an artificial public key long enough to prevent vanitygen attacks)
