Abstract
User access to a set of data stored in a distributed ledger, wherein the distributed ledger is stored by a plurality of node computing entities, is provided. A first node computing entity receives a share key request indicating that a first user account has authorized a second user account to have access to a set of data stored in the distributed ledger. A data access key (DAK) for accessing the set of data is encrypted using an encrypting key of the second user account. A block comprising the encrypted DAK is generated, signed using a signing key of the first user account, and posted to the distributed ledger. The block is authenticated using an authentication key of the first user account and accessed via a decrypting key of the second user account such that the second user account may use the DAK to access the set of data.
