Privacy-preserving ledger for blockchain and Internet of Things-enabled cyber-physical systems

Rajani Singh et al.

Summary: In recent years, decentralized applications such as Distributed Ledger Technologies and blockchain have become suitable for secure sharing of information using privacy preserving techniques like zero-knowledge protocols. However, the slow performance of traditional zero-knowledge protocols on big data is a major issue on blockchain ledgers. This paper proposes an improved zero-knowledge ledger that replaces the range-proof technique with a more efficient technique based on improved inner product based zero-knowledge proofs. Additionally, this technique allows aggregation of multiple range-proofs into a single proof, making the current zero-knowledge ledger system more efficient than the existing one.
