Sure, you can make the scheme I describe consensus based by adding the rule
tx is not valid to mine after expiry: this still keeps the simplicity I
described.

What I&#39;m describing is to implement fill-or-kill as consensus rule. Cer=
tainly, we could implement it at the P2P network level: everything is the s=

 and tx validity depends only on the nLockTime. Benevolent miners should dr=
