8/ Elsewhere, #BlockstreamResearch and partners from @UniFAU & @CISPA proposed ROAST, a wrapper for Schnorr scheme FROST, which would scale threshold signatures in L2s like @Liquid_BTC that use a federated consensus model.

9/ @Liquid_BTC functionaries currently operate using an 11-of-15 multisig wallet setup. #ROAST would not only guarantee reliable peg-outs in the presence of disruptive signers with a 67-of-100 setup (and larger) but also optimize block signing.
