Abstract

A system, method, and computer readable storage medium configured for storing encrypted data in a blockchain. To write additional data in a blockchain, a request is received at a computing node. The request is typically cryptographically signed by a user system to include a new transaction with additional data in the blockchain. The additional data is previously encrypted with an encryption key. A new block that records the new transaction with additional data in the blockchain is added. To read the additional data in a blockchain, a request is received at a computing node with a transaction identifier and a decryption key from a user system to access data journaled as part of the blockchain in the transaction database. The transaction database is searched using the identifier. In response, to finding the corresponding block in the blockchain, the data is decrypted using the decryption key.
