Subject: [Lightning-dev] We don't need R-Value,
	how OP_CODESEPARATOR saves the day
Message-ID: <CA+1nnrm7SkbxooVDCoxUWJJnsUFSmVhZy36u_pAG2Z2aMWipiQ@mail.gmail.com>

I managed to adapt the payment channel script to use less space.

This version is winning around 32 bytes in the scriptpubkey (for the R
value) as well as 70 bytes in the signature when Alice close the channel.

Alice closing the channel:
http://n.bitcoin.ninja/checkscript?savedScript=51225750-f245-45b5-a86c-6ca1e87dcafb


Bob using revocation:
http://n.bitcoin.ninja/checkscript?savedScript=c4d7ebaa-5a79-4c03-ab55-c499854f1e94


This amount to 100 bytes saved between the anchor transaction + commitment
broadcasted.
