IN LN and im not talking about session close events. im talking about within LN
"Session close events" is kinda "within LN".
even the update is not saved to your ram/hard drive in a bitcoin TX format
After commitment_signed and revoke_and_ack messages, both parties have their final commitment transaction that is understandable by the Bitcoin protocol.
msats
We all know you're obsessed with msats. They do, indeed, introduce trust. Exchanging 1 msat doesn't make sense from the Bitcoin network perspective. Whatever lightning payment you make, your balance is rounded down to satoshi once you withdraw them on-chain. For example, 1,000,999 msats is equivalent with 1,000 sats, just as 1,000,000 do. It really doesn't favor anybody to steal someone else's msats, given that they can steal less than 1,000 msats, and the opening and closing transactions cost much more than that.
Emphasis mine:
The [chain_hash] value denotes the exact blockchain that the opened channel will reside within. This is usually the genesis hash of the respective blockchain. The existence of the [chain_hash] allows nodes to open channels across many distinct blockchains as well as have channels within multiple blockchains opened to the same peer (if it supports the target chains).
