jeffro256 full-time development 2025Q4

What

The last quarter we launched the FCMP++ Alpha Stressnet. It has generally been a huge success, showing that the node can handle a reasonable level of FCMP++ stress while still revealing a large swath of improvements to make. We've tackled a lot of those issues, and are currently working through many of them now. To browse the issues reported on Github, see: https://github.com/seraphis-migration/monero/issues. This last quarter, I also solicited a review of some tweaks to the Carrot protocol from Cypherstack. I worked on and reported on a privacy vulnerability. I wrote a Carrot library in Rust. I wrote and tested a PR to improve the transaction input verification cache under load, improving block propagation and reorg times. I polished the Hot/Cold wallet support in FCMP++. I wrote a few PRs overhauling HW device / Carrot-account / hybrid-account support in the Carrot libraries. I have been slowly upstreaming commits to the Monero core repository, and I have been reviewing Berman's FCMP++ related work.

In the following quarter, I want to continue on this journey. Here is a list of tasks I want to work towards completing in rough order:

• Support new unbiased hash-to-point in the Carrot code
• Make some misc code changes to Carrot code to better match the spec
• Research/review/reach consensus/implement scaling changes as discussed in https://github.com/seraphis-migration/monero/issues/44
• Begin soliciting Carrot core implementation audits
• Help launch FCMP++ Beta Stressnet with consensus / addressing protcol changes
• Further reach out and provide support to existing hardware wallet manufacturors on how to securely support Carrot/FCMP++ scanning/spending
• Solicit help for multisig implementations of Carrot
• Help out with the FCMP++ integration wherever I can

Who

I have been contributing to the Monero core repository for over two years with a total of 125 merged commits to master thus far, with many open PRs. Over the last few months, I wrote up the Carrot specification, organized auditing, for which the community graciously funded, and began implementing it. Carrot will be the main supported addressing protocol post-FCMP++ if all goes according to plan. I also worked on the Seraphis migration project in 2023/2024.
