Normally if Alice was to spend from multiple UTXOs, she'd sign each with a signature.

With CISA, these signatures could be aggregated into a single, compact signature reducing transaction size and enabling higher throughput by utilising well understood properties of Schnorr sig.

Afaik this aggregation uses a concept similar to MuSig, where multiple public keys are combined into one.

Alice would then sign with a private key corresponding to this aggregate public key.

What would this akshually enable?

• Privacy: More efficient CoinJoins.
By reducing the signature size, CISA could make privacy-enhancing transactions like CoinJoins cheaper encouraging use and privacy as standard.

• Cost: Lower transaction fees due to smaller tx sizes.
