Say Alice and Bob are part of a partnership business that accepts Bitcoin. They store all their main funds in cold storage until the end of 3 months, when they cash out and use a new address. This cold storage is in a single address.
Both Alice and Bob have full nodes, running Bitcoin Core. They use the console feature to generate a 2-of-2 P2SH multisig address, using
They exchange each other’s public keys, and input them as arguments.
If Alice used the following syntax:
addmultisignature 2 '(<alice's key>,<bob's key>)'
and Bob used:
addmultisignature 2 '(<bob's key>,<alice's key>)'
Will they end up with the script hash and address?
Follow up questions:
Can you give certain keys more “weighting” by specifying them more than once?
Does the same logic apply to SegWit (P2WSH) multisigs?
