Abstract:

A consortium blockchain is that multiple groups of authorized members that share one ledger. Transaction validation and membership authentication are executed by trusted nodes which create and store full block (a.k.a full node). Other lightweight nodes which stored only header block request validating transaction to full node. Therefore, because the lightweight node requesting of validation transaction and sharing ledger of members between groups in consortium blockchain creates a privacy problem. In this paper, we propose an anonymous protocol based on a credential system for privacy in a consortium blockchain. This solves the problem of computation overhead and privacy in the consortium blockchain.
