  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.
