The otcDigital solution is focused on standards like CDM (with built-in cryptographic integrity and lifecycle event operations and tracking) and takes forward the dual DLT architecture that we had proposed for CBDCs a couple of years ago and implemented partly in the eThaler lab.

Questions that were answered (listen to the recording to get a sense of the answers):
Chat: Edited for brevity by VB
Jim Zhang : Is this based on Zether (seems so far it shares a lot of common cryptographic primitives)?
Answer: Robert Gabriel Jakabosky : The confidential assets is based on the MERCAT whitepaper: https://assets.polymesh.network/MERCAT.pdf. It does use the same homomorphic encryption as Zether uses.
Robert Gabriel Jakabosky : Polymesh has some features that Zether doesn't have. Like receiver affirmations (no airdrops), auditors, mediators. Also we have atomic settlements (multiple assets transfers in a single atomic transaction).
Nick : Hi Folks - just to clarify the features we are discussing here are not currently on Polymesh Mainnet. We will be making some announcements soon on how to gain access to confidential assets. If you would like to know more please reach out to @William Vaz Jones (will@polymesh.network) or myself (nick@polymesh.network) after the call.
Daniel Szego : Thanks for the great presentation, perhaps a little bit tricky question, as there are many crypto primitives in the system. How much of the system is designed with cryptographic agility in mind ? How easy is to migrate the core cryptographic primitives to another version if they turned out to be insecure, or to a post-quantum version if quantum threat turned out to be real ?
Robert Gabriel Jakabosky : Polymesh uses the Substrate framework, which make it easy to do forkless network updates. For the zk-proofs it would be possible to add a new version and allow users to migrate to the new zk-proof.
Robert Gabriel Jakabosky : For encrypted balances (Elgamal encryptions), migrating those balances to some new encryption algo. would require some zk-proof to migrate balances.
Amirreza Sarencheh : We do have standard post-quantum cryptographic primitives that can be used as alternatives (at the cost of efficiency).
