What

Work full-time 4 months on:

• FCMP++/Carrot beta stressnet.
  • Help triage and fix any identified bugs or issues.
• FCMP++ audit handling.
  • Phase 1 should be complete before July.
  • Respond to & implement any issues identified.
  • Prepare for the next audit phases to eliminate downtime between audits.
• Prepare all FCMP++ code for upstream review and merge.
  • Will submit piecemeal PR's for all line items across all Audit Phases from here.
  • Will submit piecemeal PR's from this table.
• Documentation for the FCMP++ integration.
  • WIP here (tracking PR)
• Help on whatever tasks I can to get the FCMP++/Carrot fork to mainnet, including review.
  • TODO list tracker here.
• Potentially look in to implementing Share or Perish (selfish mining mitigation) to bolster PoW security.
• 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.
  • AI is increasing load on this front.

A note: I plan to work on Serai independent from this CCS as time permits (I am prioritizing FCMP++/Carrot tasks). I would like to see Serai launched and operating smoothly.
