ChainAnchor

Principal Investigator Thomas Hardjono

Co-investigator Alex 'Sandy' Pentland


ChainAnchor is a tool which allows users to retain anonymity within a permissioned blockchain. The ChainAnchor architecture adds an identity and privacy-preserving layer above the blockchain. An anonymous identity verification step allows anyone to read and verify transactions from the blockchain but only anonymous verified identities can have transactions processed.

The use of tamper-resistant hardware provides a significant increase in security, not only for identity-related information but also for the protection of keys used by Bitcoin wallet applications.
