Is this proposal recursive?
*Coinbase transaction *
* n-txid = txid
*Non-coinbase transactions*
* replace sigScripts with empty strings
* replace txids in TxIns with n-txid for parents
The 2nd step is recursive starting from the coinbases.
In effect, the rule is that txids are what they would have been if n-txids
had been used right from the start.
