Exploring companies for external audit of Sigma and possible request for donations for this as current budget is lean. Reached out to other projects who are using Sigma who may be interested in contributing.
Shoutout to Sproxet for doing a whole ton of work that made the GUI usable and massive refactoring work, that greatly improved performance.
Still missing Znode starting support, console, mint auto denomination breakdown and advanced features like coin control
To gradually phase out QT GUI wallet once full functionality is replicated onto new GUI.
Exodus (Smart asset layer with Sigma privacy)
Work done on wallet synchronization
Mint and spend core functionality would be completed by end of week.
Additional RPCs to be coded.
Another 2-3 weeks estimated required.
Payment Codes (BIP47)
Payment codes allow a single address to be shared publicly but without allowing outsiders to see payments made to it.
Has certain advantages over stealth addresses in that it can be supported by light wallets and also payments to payment codes are indistinguishable from regular payments.
Development is about 30% in progress with expected completion in about a month.
Development is still being done on QT GUI for the moment but will need porting work for new GUI.
Lelantus
Lelantus+ paper that improves proving time at the cost of increased proof sizes and slightly increased verification time has completed security proofs. To distribute to friendly researchers first before publishing.
Informal discussion with Sarang Noether from Monero Research Labs on possibility of opening up our cryptographic libraries for review/comment.
Research has changed focus from from scaling Lelantus anonymity sets into solving the requirement to ‘self-spend’ after receiving a direct anonymous transaction. Doing this greatly improves Lelantus usability and also makes it likely to be implemented in Monero (although in a different way).
Zcash’s approach in solving the self-spend issue cannot be applied to us as they use a general arithmetic circuit zk proof to do this and neither do any of the ring signature models.
Decision not to rush Lelantus implementation but to take the time for review.
Mobile App with Sigma
Team of 3 people has been formed with a rough road map to make Sigma enabled mobile wallet.
To work together with core team to develop the backend functionality required to communicate Sigma anonymity sets.
Edge wallet still prime candidate to be used as a base. Shout out to Paul Puey for his time.
Estimated time for completion is around 4 months but a lot of possible unforeseen hurdles.
Work done can be used for Lelantus mobile as well.
Core Upgrade and Deterministic Masternodes/Chainlocks
Aiming for testnet to be setup soon with the new client.
Nodes need to be re-setup when deterministic masternodes to come into play as we also don’t have any sporks features for centralization reasons. Queue reset.
To provide at least 1.5 months for hard fork notification.
