UkoeHB submits Seraphis PoC CCS proposal

Monero contributor UkoeHB1 has submitted a CCS proposal2 that aims to develop a Seraphis C++ proof-of-concept3:

Hi all, after some encouragement I decided to request funding for my ongoing work on Seraphis. Specifically, funding for future work on the Seraphis C++ proof-of-concept that I have been developing since the second week of September.

My goal is for this code to be 95% production-ready.

UkoeHB shares several potential benefits and costs when comparing Seraphis/Lelantus-Spark with Triptych and RingCT:

He suggests that the last con might actually be an opportunity to improve Monero:

Replacing old addresses is an opportunity to deprecate ‘normal addresses’ in favor of ‘subaddresses’ only. A uniform address format would simplify UX and various implementation details.

If this gets funded, the following tasks will be prioritized:

Once performance tests are complete, I will take a break of 1-4 weeks to finish the Seraphis paper.

UkoeHB has previously contributed to Monero by co-authoring Zero to Monero (1st4 and 2nd5 edition) and submitting several MRL & Monero core issues and PR’s6.

Total funding: 92.6 XMR (50 USD + 0.2 XMR Rate).

ETA: TBD (6 weeks @ 40hr/wk = 240hrs).

A previous MO report7 discussing Seraphis/Lelantus-Spark vs Triptych might be relevant to this proposal.

There is a high probability that one of the above will be part of Monero in the future. Regardless of which one the community picks, there is little doubt that the amount of decoys will increase as the ring signatures decrease in size and become more efficient, thus ultimately making Monero better.

Update: the proposal was fully funded.
