Subject: [Lightning-dev] Minor tweaks to blinded path proposal
Message-ID: <87k0uj8cqh.fsf@rustcorp.com.au>


See:
        https://github.com/lightningnetwork/lightning-rfc/blob/route-blinding/proposals/route-blinding.md

1. Can we use additive tweaks instead of multiplicative?
   They're slightly faster, and supported by the x-only secp API.
2. Can we use x-only pubkeys?  It's generally trivial, and a byte
   shorter.  I'm using them in offers to great effect.

Thanks!
Rusty.
