In my experience, best process for standardizing something= is:

1) Somebody has a great idea
2) They impl= ement it
3) Everybody agrees, "Great idea!" and they co= py it.
4) Idea gets refined by the people copying it.
5) It gets st= andardized.

Mutisig wallets are at step 2 right no= w. BIP is step 5, in my humble opinion...

I was wondering if there would be merit in a kind of BIP f= or a payment protocol using multisig?

Currently, setting up a = multisig is quite a feat. Users have to exchange public keys, work out how = to get the public keys from their addresses. If one of the parties are not = savvy enough, an malicious party could easily be setup that was 2 of 3 inst= ead of 2 of 2 where the malicious party generates the multisig address+scri= pt and thus be able to run off with funds anyway.


What are your thoughts?
