Privacy Enhanced Distributed Ledger Technology and Hyperledger Implementation

Blockchain offers new and significant features for distributed systems, but the immutability of data blocks limits its utility where it must be possible to delete private or security-sensitive data. NIST has designed and implemented in Hyperledger Fabric, a new form of distributed ledger technology (DLT), a data block matrix, which provides the integrity assurance of blockchain but allows for controlled revision or deletion of data. Blockmatrix extends the range of application for blockchain solutions by solving the conflict between privacy regulations and blockchain, and allowing exception management.
