Data isolation in distributed hash chains

Abstract:

Certain aspects of the present disclosure provide techniques for managing data in a plurality of nodes of a distributed system. Embodiments include storing, by a node of the plurality of nodes, sensitive data in a block of a hash chain. Embodiments further include determining, by the node, that the sensitive data should not be distributed to other nodes of the plurality of nodes. Embodiments further include distributing, by the node, a limited version of the block to the other nodes. The limited version of the block may comprise a hash and a pointer to a previous block of the hash chain, and the limited version of the block may not contain the sensitive data.
