ING applies the zero-knowledge proof to R3's Corda notary service

According to CoinDesk, Dutch International Group (ING) announced at the CordaCon Developers Conference on Tuesday that it helped solve the security/privacy issues that currently plague Corda users. The bank's blockchain team does this by applying Zero Knowledge Proof (ZKP) to the Corda notary service, which is the only means of network verification transactions and prevents duplicate spending.
