What

The last quarter I implemented the core cryptography for Carrot. I will note that preliminary performance tests put Carrot scanning at about 30% faster on CPU usage versus scanning today, mostly thanks to the use of the X25519 ECDH library mx25519. I also implemented pruned cryptonote::transaction construction and scanning for Carrot. The FCMP++ integration and Carrot integration are finally meeting ends and are almost ready for hot path integration. This next quarter, I want to continue this work to get a testnet out ASAP.

To recap, here is a list of things I will attempt to work on this quarter, in rough order of execution:

• Integrate Carrot scanning/transaction construction into main wallet codepaths
• Provide support to existing hardware wallet manufacturors on how to securely support Carrot outputs
• Use benchmarkings and static analysis to inform MRL decisions on transaction weight discussions etc
• Begin soliciting Carrot core implementation audits
• Provide Rust implementation of Carrot for Serai/Cuprate
• 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 84 merged commits to master thus far, with many open PRs. Over the last few months, I wrote up the Carrot specification, organized []auditing](https://github.com/cypherstack/carrot-audit), 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.
