🗒️ Summary of this message: A proposed method for reducing address length in Bitcoin transactions may not be practical due to the need to distribute pubkeys ahead of time.

On second thought, I'm not sure this is workable. You would have to
distribute each party's pubkey ahead of time, otherwise you run the risk
that a party falls off the face of the earth and then you can't provide
the pubkeys to have hash(pubkey1+2+3) EQUALVERIFY.

If you have to distribute the pubkeys ahead of time, then the reduction in
address length becomes moot.

So it seems to be either distribute the pubkeys or distribute the
hash160(pubkey)'s.
