So...
How many years until we think a 2^84 attack where the work is an ECDSA
private->public key derivation will take a reasonable amount of time?
And Ethan or Anthony: can you think of a similar attack scheme if you
assume we had switched to Schnorr 2-of-2 signatures by then?
And to everybody who might not be reading this closely: All of the above
is discussing collision attacks; none of it is relevant in the normal case
where your wallet generates the scriptPubKey.
