Always Look On The Bright Side of the Annex #9
Conversation
Is there any reason not to PR the draft BIP to the bips repo? Non "Final" BIPs can be updated essentially at will, as I understand it... I don't think you can have a package weight be consensus enforced (if you just see the block, how do you know what the package was); so that feature would be more "package weight committed to by signature", I think. |
Yeah I need to refine some BIP sections though then no reason not to PR the draft to the bips repo.
Maybe you can introduce the notion of package at the consensus-level, you validate the whole chain of transaction since the latest UTXO set. Though that sounds gross. Yeah "package weight committed to by signature" could work as would be a restraint enforced from the spent scriptpubkey. |
So to my mind there's two parts:
is this correct? |
Yes, once we define a format at the policy-level, if we would like to enforce another data format at the consensus-level, all the annex signers would need to upgrade their data fields, as otherwise their transactions could be rejected for being invalid. |
CI passing at a minimum :)

Another use-case, contract-level timelock.
|
Note to myself: another "could-be" use-case "amount wildcard" distribution in non-interactive channel (see ariard/bitcoin-contracting-primitives-wg#19) |
Suggest targeting this against 24.0 branch. (Apparently you can do that via the [Edit] button!) |
Great to see this, as I think this solves in an elegant way the one missing bit in the specs of the MATT proposal: how to make sure that the witness elements that are part of the contract execution are not malleated? For example, this game requires parties to commit to a number, which should therefore be signed or miners could just change it. Those elements can be thought of as "arguments" during the contract execution. With a PUSH_ANNEX_RECORD opcode, this would allow to either:
Either way, this is clearly more efficient than the alternative solution of adding OP_CHECKSIGFROMSTACK, which would require one more signature check. |

- What does "higher-mask type" mean?
- Why using the ugly variable naming notation? :)

Completely updated the code here, there should be new text. Dropped "higher-mask type" reference. On the ugly variable naming notation, sounds to me the one in vigor for a bunch of interpreter.cpp
, see CheckSequence()
though feel free to suggest something else.

Updated at 4ccd693. Thanks for the reviews! Still I'll think to add a dummy annex entry and more functional tests. See the BIP for open questions.
If the "arguments" are bitcoin objects like curve points, amounts or scriptpubkeys, introducing in the annex might allow more flexibility for other use-cases. I don't know if the second approach is not more verbose (though you only need few "hash" annex entries). |

note this is a bitmask above not an assignment
There's a bunch of code improvements you can make: snake case,
This would be great!
I don't see any open questions in the BIP.
Can you elaborate on this? The "other use-cases" I mean. Other from what? |
a basic test case would be great for me to trace through for better understanding fwiw |
The BIP PR opens against the repository: bitcoin/bips#1381
One use-case you can think of is delegation with "blessed keys" committed as annex record. Alice signs a annex with Bob's key, allowing Bob to spend the output at anytime without Alice further interactivity.
Working on the "block-feerate lock-point" mentioned above: https://github.com/ariard/bitcoin/tree/2023-01-feerate-point, as a solid example of what the annex can be useful for :) |

Build on top of #4.
This PR proposes a validation format for the taproot annex. It allows to extend the usual transaction fields with new data records allowing witness signatures to commit to them. The data records can be subject to new validation rules.
So what's the PR standard we're looking for new softfork idea? There is a WIP BIP available here:
https://github.com/ariard/bips/blob/2022-07-bip-annex/bip-annex.mediawiki
List of following use-cases that could be supported with the annex:
