is somebody here implementing cross-chain atomic swaps? like between bitcoin/monero?

i see it get mentioned every few months but tbh i never follow up on the conversations..

Yes. kayabaNerve has a PoC I believe. zkao and h4sh3d[m] want to build something further.

kayabaNerve: i don't see anything on your github

andytoshi: github.com/MerosCrypto/asmr

andytoshi, for what concerns discrete log equality accross groups, 2 implementations so far:

andytoshi: This was also recently released -> medium.com/comit-network/monero-bitcoin-atomic-swap-1cab015d7af9

andytoshi: hi - yes, we've been working for quite a long time on it and we took more time since beginning of this year. You can find the base protocol here: eprint.iacr.org/2020/1126

But there's already some improvements that came out recently about simplifying the bitcoin transaction "footprint"

I started this work back in 2017, but I managed to complete it only recently with the cross group dleq and the adaptor signatures from lloyd fournier

andytoshi, and LLFourn/secp256kfun #29

thanks all!
