[Lightning-dev] DRAFT: interactive tx construction protocol

[Antoine Riard]

Hi Max,

Sorry by transaction format I didn't mean a binary transaction format,
but format like we use in BOLT3 :
https://github.com/lightningnetwork/lightning-rfc/blob/master/03-transactions.md

My concern is, e.g LN implementations setting nLocktime to 0x00000000,
Coinjoin wallets always disabling nSequence and core wallet transactions
doing anti-fee snipping. Now even if all of them are using Taproot outputs
you're still leaking what protocol/tooling you're using to an external
observer
due to discrepancies in transaction fields. So we should obfuscate or using
standard values as much as protocol semantics let us doing it to break chain
analysis heuristics.
