10:48:09 Built a non-custodial 2-of-3 multisig escrow for XMR — FROST threshold sigs + 10:48:09 CLSAG, runs in WASM (browser). Live on mainnet. 10:48:09 looking at FCMP++ adaptation. The FROST DKG should carry over since it's 10:48:09 Schnorr-based, but the signing part will need rework for the new membership 10:48:09 proofs.[... more lines follow, see https://mrelay.p2pool.observer/e/4Pnau-IKMEFxR2cz ] 10:53:23 The cryptography itself is already written in the FCMP++ libraries. 10:55:00 Good to know. Is there a multisig signing spec/API I should look at? 10:55:01 My implementation uses a coordination server that facilitates signing rounds 10:55:01 without holding private keys (derives commitments from public data only). 10:55:01 Wondering if that pattern maps to the new libs or if the approach is different. 10:56:49 is it open source? 11:05:23 I believe this is used privately 11:06:51 then we will wait for spirobel and milestone 3 https://ccs.getmonero.org/proposals/spirobel_monero_browser_wallet.html 11:09:15 Not currently. It's a commercial product 11:09:15 But I'm open to discussing the cryptographic approach or contributing 11:09:15 to Carrot multisig research separately. 11:09:15 Aware of spirobel's work. Different scope — my focus is escrow infrastructure [... more lines follow, see https://mrelay.p2pool.observer/e/kNSovOIKT2NWQWxp ] 11:55:07 @onyx_prot:matrix.org: Not to be unappreciative, just to let you know what the landscape is:Monero already has a FROST-inspired signing protocol for CLSAGs, with security proofs, and an audited FOSS implementation.The bones of the implementation are slated for use within FCMP++ which already has the cryptographic protocol defined, and is already slated for review as part of the FCMP++ R&D effort. 11:55:30 That doesn't comment on how wallets represent these bones but this is already an area of research with a long history. 13:19:14 Makes sense. My interest is specifically the wallet/coordination layer — 13:19:14 how to facilitate 2-of-3 signing rounds for escrow without custodying keys. 13:19:14 I'll follow the FCMP++ R&D and look at the existing FROST implementation. 13:19:14 Thanks for the context.
