2/ But first, an update on layer-2 network capacity. Both the #LightningNetwork & @Liquid_BTC have reached new #Bitcoin capacity highs despite the drawdown in Bitcoin price for a combined capacity of 7,550 BTC.

3/ In Lightning news, a minor release (v0.11.1) from the @Core_LN crew, arriving on the tail of a major release that added channel multiplexing & a new gRPC API plugin.

Upgrade to the latest release here: [https://github.com/ElementsProject/lightning/releases/tag/v0.11.1]

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.

Whitepaper 👇

https://eprint.iacr.org/2022/550.pdf

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.
