The Ritva Blockchain: Enabling Confidential Transactions at Scale

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 plat- form that champions privacy called RVChain. RVChain takes advantage of trusted execution environment to offer confidentiality protection for transactions, and scale the throughput of the network in proportion with the number of network participants by supporting parallel shadow chains
