The Ritva Blockchain: Enabling Confidential Transactions at Scale

TL;DR

The Ritva Blockchain (RVChain) is a scalable, privacy-preserving distributed ledger platform that uses trusted execution environments and parallel shadow chains to enhance transaction confidentiality and throughput at scale.

Contribution

This paper introduces RVChain, a novel blockchain platform that combines trusted execution environments with parallel shadow chains to improve scalability and confidentiality.

Findings

RVChain achieves proportional scalability with network size.

RVChain effectively protects transaction confidentiality.

The platform demonstrates improved throughput in large networks.

Abstract

The distributed ledger technology has been widely hailed as the break-through technology. It has realised a great number of application scenarios, and improved workflow of many domains. Nonetheless, there remain a few major concerns in adopting and deploying the distributed ledger technology at scale. In this white paper, we tackle two of them, namely the throughput scalability and confidentiality protection for transactions. We learn from the existing body of research, and build a scale-out blockchain platform that champions privacy called RVChain. RVChain takes advantage of trusted execution environment to offer confidentiality protection for transactions, and scales the throughput of the network in proportion with the number of network participants by supporting parallel shadow chains.
