AbstractBlockchain provides a distributed ledger recording a globally agreed, immutable transaction history, which may not be suitable for Fintech applications that process sensitive information. This paper aims to solve three important problems for practical blockchain applications: privacy, authentication and auditability. Private transaction means that the transaction can be validated without revealing the transaction details, such as the identity of the transacting parties and the transaction amount. Auditable transaction means that the complete transaction details can be revealed by auditors, regulators or law enforcement agencies. Authenticated transaction means that only authorized parties can be involved in the transaction. In this paper, we present a private, authenticated and auditable consortium blockchain, using a number of cryptographic building blocks.
