01:44:20 <UkoeHB> Hi guys, I have been working on a new tx protocol called Seraphis. An outline is here: https://gist.github.com/UkoeHB/24f6be6125684046c5c4d9f49351bccf. I am planning to write a preprint for it, but that is weeks or months away from now.
02:02:09 <UkoeHB> With a Groth/Bootle (Grootle) ring signature for membership proof, this would look similar to Triptych/etc in terms of size/verification costs. The main functional difference is how key images (linking tags) are constructed.
02:02:24 <UkoeHB> Grootle one-of-many proof*

19:10:50 <UkoeHB> The Seraphis key images are Grootle-friendly (fixed base point), multisig-friendly (linear on private spend key), and allow full balance recovery with the private view key (inversion component based on private view key).
19:26:00 <UkoeHB> The essential difference compared to previous tx protocols is membership proofs sign a commitment to zero on the output address, instead of proving knowledge of the private key and constructing key images directly.
