Bip270 is a protocol for you and I establishing the terms of our transaction:

- You say me the total amount (1000 USD) to be paid.

- I answer you that I will pay you using 1000 utxos (from the thousands that are in my wallet)

- your wallets creates a thousand 1 USD transactions, each one from one of my UTXOs to one of your addresses.

- I sign the 1000 transactions at once

- you broadcast the 1000 transactions to the miners, and notify me.

- for each confirmation you can send me a message

- when enough confirmations, you notify me that the payment is ok. And then send me the invoice, if required.

All this process is made automatically by our wallets. I only have to say OK two times.

All this info is stored by you and me (or in Metanet) and it's extra proof for you and me in court or tax authorities, so it's even more government friendly.

But for the rest of the world is fungible (harder to monitor).
