    • 01:28:54 Half aggregation of BIP340 signatures: Jonas Nick posted to the Bitcoin-Dev mailing list a draft BIP and blog post about half aggregation of Bitcoin’s schnorr signatures. As mentioned in the blog post, the proposal “allows aggregating multiple schnorr signatures into a single signature that is about half as long as the sum of the individual signatures. Importantly, this scheme is non-interactive, which means that a set of signatures can be half-aggregated by a third party without any involvement from the signers.”
