What

Work full-time 4 months on:

• Completing the FCMP++ integration.
  • We launched the alpha stressnet, and it's currently on release version 1.4: https://github.com/seraphis-migration/monero/releases
  • We are currently finishing ironing out the core issues identified during the alpha stressnet.
    • Here is a more detailed status update: https://repo.getmonero.org/monero-project/ccs-proposals/-/merge_requests/600#note_33193
  • Once alpha stressnet participants confirm the core issues are ironed out, I would like to begin preparing for the beta stressnet.
    • I will continue to help triage and fix identified bugs/issues.
    • The plan to mainnet: alpha stressnet, beta stressnet, finish code review/audits, testnet, mainnet.
    • Here is the TODO list for beta: https://github.com/seraphis-migration/monero/issues/166
  • Work on the following, some of which @jeffro256, @0xFFFC0000, and @articmine are already working on:
    • v1.5 of the alpha stress network.
    • Sync failures: https://github.com/seraphis-migration/monero/issues/244
    • One user (u/Lyza) is reporting unexpectedly slow time to verify FCMP++ proofs during sync on their machine: https://github.com/seraphis-migration/monero/issues/246
    • Collaborate with @0xFFFC0000 to get tx relay v2 across the finish line.
    • Continue deliberating on, reviewing, and implementing updated fee/scaling logic for FMCP++.
      • We need to reach rough consensus on the scaling approach for the beta stress network: https://github.com/seraphis-migration/monero/issues/44
    • Review @jeffro256's cold wallet <> hot wallet integration.
    • Review @jeffro256's HW wallet work.
    • Multisig.
      • A) update multisig sync to manage the tree correctly on import.
      • B) use monero-wallet for the core protocol.
    • See this TODO list tracker.
• Complete documentation for the FCMP++ integration.
  • WIP here (tracking PR)
• Continue submitting piecemeal FCMP++ PR's to the main Monero repo.
  • See this upstreaming plan here: https://github.com/seraphis-migration/monero/issues/103
  • I would like to get the crypto PR's audited as well, and will work on pushing that forward during this proposal.
• Continue Seraphis wallet library work:
  • My next task on this front is to bring the Serpahis lib async scanner into the current wallet API (source)
    • In the latest round of tests, I observed scanning speed-ups of 50-60% with a clearnet remote node, 35-45% with a tor node, 25-35% with a local node.
    • The async scanner has already undergone a round of review (source)
    • To be usable in the wallet API, the following still needs to be implemented: - A mutable subaddress lookahead (source) - Pool scanning (source) - A clean way to save tx metadata (source) - Integrate the FCMP++ tree builder + Carrot scanning.
• Misc. high priority tasks as they arise, including vulnerability response as requested.

A note: once I've completed all blocking work on the FCMP++ / Carrot integration, I plan to work on Serai independent from this CCS. I would like to see Serai launched and operating smoothly. I would then return to continue Seraphis wallet library work.
