user133959: 3 Entities (A/B/C) create a collaborative Multisig Wallet (e.g. 2-of-3).
A creates an unsigned TX and shares it with B/C. They (B/C) sign and broadcast.
Looking at the TX on the network, can A make any difference who signed first? So, are signatures in the signing process appended to each other OR do they follow the specific order the multisig-setup was initially constructed?

user5406: In the context of OP_CHECKMULTISIG, the signatures must appear in the same order as the public keys are listed.
The signers can created the signatures in a different order than that, but that cannot be determined from the transaction.
