Half-Aggregation of BIP 340 Signatures

Blockstream Research shares its progress on the aggregation of signatures based on curve secp256k1, including an early draft BIP for non-interactive half-aggregation of BIP 340 Schnorr signatures. Half-aggregation signatures have a variety of potential upsides, such as cutting down on the size of mainchain transactions and reducing the bandwidth requirement of off-chain networks.
