Abstract
A method performed by a system of a host organization for providing a right to forget data in a blockchain, the system providing a blockchain interface to a blockchain on behalf of a plurality of tenants of the host organization each serving as nodes in a blockchain network. The method includes receiving a request including an identifier of a requestor, the request to access transaction data designated as private, requesting access to the transaction data from nodes in the blockchain network including the identifier of the requestor, receiving at least one shared secret from a node in the blockchain network indicating consensus to access the transaction data by the requestor, and denying access to the transaction data in response to receiving insufficient shared secrets from the nodes indicating the transaction data is permanently unavailable to access.
