I am currently working on nested multi-party digital signatures for improved privacy, programmability and self-custody on Bitcoin.

• ➣ By multi-party signatures, I am referring to schemes where many keys are aggregated into a single key,
• ➣ and the owners of the partial keys can collaborate to generate digital signatures for their shared aggregate key.
• ➣ By nested multi-party signatures, I am referring to multi-party signature schemes where a single partial key can itself be the result of another group of parties aggregating their keys,

and these “nested” parties can collaboratively generate all of the messages required to generate their part of a top-level aggregate signature.
