2021 Jan.

• The new version of Gary’s NIT scheme updated a lot https://eprint.iacr.org/2020/1064.pdf, I have to read it again to understand it well for preparing the proper adaptation on the design to compensate those changes.
• The updated scheme need a bigger transaction size than before, especially on the Output R signature parts, there could be an further optimization on this according to Gary but not finalized yet.
• “Distributed Message Pool” design review.

Next step: Going back the coding part of the node NIT branch, to complete the basic structure parts.

• A summary of misc versions in mwc node codebase: Misc Versions in Node Codebase

• Rollout/Deployment (HF2) Plan of NIT: Non-Interactive Transaction and Stealth Address

• Per-block non-interactive Schnorr signature aggregation proposal (draft): Per-block non-interactive Schnorr signature aggregation

• MWC NIT Address design: Request for Comments - MWC NIT Address

2021 Mar.

• Mainly on the continuing implementation on node: https://github.com/mwcproject/mwc-node/pull/24/commits .
• NIT sum (2) equation balance validation logic is almost done, still a bootstrap logic need to be implemented.
• The next step is unit tests on these validation logic of NIT, including R signature, Inputs signature, and two sum validation.
• In this month, another heavy task is the critical fix on the cache bug (inflation bug) attack.

The progress of node implementation is a little bit delayed because of other tasks, I will catch up in next one or two weeks. The node implementation was expected to be completed in Mar. and I should be available to start wallet part from middle of Apr.
