The distributed ledger technology has been widely hailed as the breakthrough technology. It has realised a significant 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 our research, 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 RV-Chain.
RV-Chain takes advantage of a 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.
