cryptography – Utilizing key aggregation (multsig) in P2TR script path spends
I do know that it’s potential to create a 2-2 multsig utilizing Taproot by combining each non-public keys into one public key and defining that as the important thing path spend. I additionally know that it’s potential to make use of Tapscript to do the identical factor with a script path spend utilizing OP_CHECKSIGADD.
Is it additionally potential to make use of key aggregation within the script path spend, by simply offering a public key and signature however doing the identical key aggregation as in the important thing path spend? In that case, wouldn’t it ever make sense to make use of a “regular” OP_CHECKSIGADD operation within the case of multisig (not threshold signatures).
