Re: [bitcoin-dev] Draft-BIP: Ordinal Numbers

[damian@willtech.com.au]

Well done, your bip looks well presented for discussion. You say to 
number each satoshi created? For a 50 BTC block reward that is 
5,000,000,000 ordinal numbers, and when some BTC is transferred to 
another UTXO how do you determine which ordinal numbers, say if I create 
a transaction to pay-to another UTXO. The system sounds expensive 
eventually to cope with approximately 2,100,000,000,000,000 ordinals. If 
I understand ordinals 0 to 5,000,000,000 as assigned to the first 
Bitcoin created from mining block-reward. Say if I send some Bitcoin to 
another UTXO then first-in-first-out algorithm splits those up to assign 
1 to 100,000,000 to the 1 BTC that I sent, and 100,000,001 to 
5,000,000,000 are assigned to the change plus if any fee?-DA.
