Tom,

It's clear that you have some ra= ther large gaps in your knowledge of Bitcoin, its rules, implementation and g= ame theory. I highly encourage you spend some time learning more about these= things before continuing posting here. 

https://www.reddit.com/r/BitcoinBeginners/ is a= good place to start. It's a safe place where you can ask any question you w= ant without fear of being laughed at.
Kind regards,


Jean-Paul

Can you tell me where it is enforced?

The only place I found was here;
https://github.com/bitcoin/bitcoin/blob/master/src/validation.cpp#L1793

which doesn=E2=80=99t enforce it, all that code does is check that the txid i= s
unknown or fully spent.
And since the below idea from Russel would change the txid, it would seem no=
full client would reject this.

Maybe its in a BIP, but I can=E2=80=99t find it in the code.
