Hi all,

Just under three years ago there was some discussion about the BIPs repo, with the result that Kalle became a BIPs editor in addition to Luke, eg:

 * https://gnusha.org/bitcoin-core-dev/2021-04-22.log
 * https://lists.linuxfoundation.org/pipermail/bitcoin-dev/2021-April/018859.html

It remains, however, quite hard to get BIPs merged into the repo, eg the following PRs have been open for quite some time:

 * #1408: Ordinal Numbers; opened 2023-01-21, editors comments:
     Kalle:
       https://github.com/bitcoin/bips/pull/1408#issuecomment-1421641390

       https://twitter.com/LukeDashjr/status/1735701932520382839

The range of acceptable BIPs seems to also be becoming more limited, such that mempool/relay policy is out of scope:

 * https://github.com/bitcoin/bips/pull/1524#issuecomment-1869734387

Despite having two editors, only Luke seems to be able to assign new numbers to BIPs, eg:

 * https://github.com/bitcoin/bips/pull/1458#issuecomment-1597917780

There's also been some not very productive delays due to the editors wanting backwards compatibility sections even if authors don't think that's necessary, eg:

 * https://github.com/bitcoin/bips/pull/1372#issuecomment-1439132867

Even working out whether to go back to allowing markdown as a text format is a multi-month slog due to process confusion:

 * https://github.com/bitcoin/bips/pull/1504

Anyway, while it's not totally dysfunctional, it's very high friction.

There are a variety of recent proposals that have PRs open against inquisition; up until now I've been suggesting people write a BIP, and have been keying off the BIP number to signal activation. But that just seems to be introducing friction, when all I need is a way of linking an arbitrary number to a spec.

So I'm switching inquisition over to having a dedicated "IANA"-ish thing that's independent of BIP process nonsense. It's at:

 * https://github.com/bitcoin-inquisition/binana

If people want to use it for bitcoin-related proposals that don't have anything to do with inquisition, that's fine; I'm intending to apply the policies I think the BIPs repo should be using, so feel free to open a PR, even if you already know I think your idea is BS on its merits. If someone wants to write an automatic-merge-bot for me, that'd also be great.

If someone wants to reform the BIPs repo itself so it works better, that'd be even better, but I'm not volunteering for that fight.

Cheers, aj

(It's called "numbers and names" primarily because that way the acronym amuses me, but also in case inquisition eventually needs an authoritative dictionary for what "cat" or "txhash" or similar terms refer to)

I've no idea how to reform BIPs, but we have a similar problem with the Blockchain Commons Research (BCR) vs Proposals (BCP), vs. specifications that are emerging in various other standards groups (IETF, W3C, and we have desire to submit some of these as BIPs as well).

We do a few things differently, one of which in particular might be useful for the future of BIPs: we reset the numbers every year. So the first new BCR (research proposal) for 2024 would be 2024-01. Also, when there is a major change in an old BCR, we create a new number for it in the new year it is update.

We also have a concept called "Status", which is a progression that only moves forward if BCRs are actually implemented with a reference implementation, and advances further when they have multiple implementations (and thus are qualified moved over to BCP repo as it is somewhat stable and no longer "research".). A last form is when a specification has moved to be controlled by another standards group (such as a BIP). If only one organization implements a BCR, it will never advance to BCP.

Some form of Status for BIPs inspired by this concept could track if a BIP was ever actually implemented by someone, or more ideally, implemented by multiple people in multiple organizations, ideally in multiple languages.

Here is how we currently do status, and the status of our current specifications: https://github.com/BlockchainCommons/Research/blob/master/README.md#status

Each BCR has a status which is indicated by a symbol. SymbolTitleDescription ❌❌ Withdrawn Of historic interest only. Withdrawn either because never came into use or proved sufficiently problematic that we do not recommend its usage in any way. ❌ Superseded Superseded by a newer BCR. We do not suggest implementing as an output format, but you may still wish to implement as an input format to maintain backward compatibility. 📙 Research Contains original research or proposes specifications that have not yet been implemented by us. Offered to the community for consideration. ⭐️ Reference Implementation At least one reference implementation has been released, usually as a library, and may include demos or other supporting tools. This specification still remains very open to change because it has not yet (to our knowledge) been implemented by additional parties. ⭐️⭐️ Multiple Implementations At least two (known) implementations exist, at least one not by the owner of the reference implementation. Has demonstrable community support. May still change due to the needs of the community, but community feedback will be sought. ⭐️⭐️⭐️ Standards Track Typically at least two implementations, and is considered stable and ready for standardization. Being proposed as a BIP, IETF Internet Draft, or some other standardization draft format. Will typically be moved to the BCP repo <https://github.com/BlockchainCommons/bcps>. Though changes may still be made to the specification, these changes will exclusively be to allow for standardization, and will be conducted with community feedback. ⭐️⭐️⭐️⭐️ Standardized A specification has been standardized as a an IETF RFC, BIP, or approved by some other standards body.

❌❌ after another status symbol is read, "...but withdrawn" and ❌ is read, "...but superseded".

Perhaps a BIP 3 is in order, but most of the real issue is simply a matter of volunteer time.

AJ's attempt to conflate that with his own personal disagreements with how BIPs have always worked, is unrelated.

Hey Luke

I'd be happy to pick up working on BIP 3 again ([0], [1]) in light of this issue and others that are repeatedly cropping up (e.g. confusion on the recommended flow for working on proposed consensus changes, when to open a pull request to bitcoin-inquisition, when to open a pull request to Core, when to include/exclude activation params etc).

I don't think there is much I personally disagree with you on with regards to BIPs but one issue where I do think there is disagreement is on whether proposed default policy changes can/should be BIPed.

I previously drafted this on proposed default policy changes [2]:

"To address problems such as pinning attacks on Lightning and multiparty protocols (e.g. vaults) there are and will continue to be draft proposals on changing the default policy rules in Bitcoin Core and/or alternative implementations. As these proposals are for default policy rules and **not** consensus rules there is absolutely no obligation for Bitcoin Core and/or alternative implementations to change their default policy rules nor users to run any particular policy rules (default or otherwise). The authors of these draft proposals are clearly recommending what they think the default policy rules should be and what policy rules users should run but it is merely a recommendation. There are a lot of moving parts, subtleties and complexities involved in designing default policy rules so any recommendation(s) to significantly upgrade default policy rules would benefit from being subject to a spec process. This would also aid the review of any policy related pull requests in Bitcoin Core and/or alternative implementations. An interesting recent case study washttps://github.com/bitcoin/bitcoin/pull/22665and Bitcoin Core not implementing the exact wording of BIP 125 RBF. In this case (for various reasons) as a response Bitcoin Core just removed references to BIP 125 and started documenting the replacement to BIP 125 rules in the Bitcoin Core repo instead. However, it is my view that recommendations for default policy rules should be recommendations to all implementations, reviewed by Lightning and multiparty protocol developers (not just Bitcoin Core) and hence they would benefit from being standardized and being subject to a specification process. I will reiterate once again though that policy rules are **not** consensus rules. Consensus rules are much closer to an obligation as divergences from consensus rules risk the user being forked off the blockchain and could ultimately end up in network splits. This does not apply to policy rules."

Are you open to adjusting your stance on proposed policy changes being BIPed? I do think it really stunts work on proposed default policy changes and people's ability to follow work on these proposals when the specifications for them are littered all over the place. I've certainly struggled to follow the latest state of V3 policy proposals without clear reference points for the latest state of these proposals e.g. [3]. In addition some proposed consensus change BIPs are starting to want to include sections on policy (e.g. BIP345, OP_VAULT [4]) where it would be much better if they could just refer to a separate policy BIP rather than including proposals for both policy and consensus in the same BIP.

Thanks for your long and continued work on the BIP process. It is thankless work and we don't see the alternative futures where all sorts of garbage was merged and given BIP numbers because the BIP editors just merged everything without looking at it and not caring about quality standards.

Thanks Michael

Thank you for doing this!

Question: is there a recommended way to produce a shorter identifier for inline use in reading material? For example, for proposal BIN-2024-0001-000, I'm thinking:

- BIN24-1 (references whatever the current version of the proposal is)
- BIN24-1.0 (references revision 0)

I think that doesn't look too bad even if there are over 100 proposals a year, with some of them getting into over a hundred revisions:

- BIN24-123
- BIN24-123.123

Rationale:

- Using "BIN" for both full-length and shortened versions makes it explicit which document set we're talking about

- Eliminating the first dash losslessly saves space and reduces visual clutter

- Shortening a four-digit year to two digits works for the next 75 years. Adding more digits as necessary after that won't produce any ambiguity

- Although I'd like to eliminate the second dash, and it wouldn't introduce any ambiguity in machine parsing for the next 175 years, I think it would lead to people interpreting numbers incorrectly. E.g., "BIN241" would be read "BIN two-hundred fourty-one" instead of a more desirable "BIN twenty-four dash one"

- Eliminating prefix zeroes in the proposal and revision numbers losslessly saves space and reduces visual clutter

- A decimal point between the proposal number and revision number creates less visual clutter than the third dash and still conveys the intended meaning

- Overall, for the typical case I'd expect---BIN proposals numbered 1-99 with no mention of revision---this produces strings only one or two or characters longer than a typical modern BIP number in shortened format, e.g. BIN24-12 versus BIP123.

Thoughts?

-Dave

Hi AJ,

I like the idea and agree with everything you shared in the email except one thing:

I think "authority" is a strong word especially in bitcoin and this process could even work with BINN (Bitcoin Inquisition Numbers And Names). IANA (a function of ICANN) is different thing altogether which was founded by US government.

Bitcoin Inquisition is based on signet, which is a centralized blockchain for testing run by a central authority whose consensus is based on signatures from that authority. Using the term "authority" in this context is fine.

I do think it really stunts work on proposed default policy changes and people's ability to follow work on these proposals when the specifications for them are littered all over the place. I've certainly struggled to follow the latest state of V3 policy proposals without clear reference points for the latest state of these proposals e.g. [3]. In addition some proposed consensus change BIPs are starting to want to include sections on policy (e.g. BIP345, OP_VAULT [4]) where it would be much better if they could just refer to a separate policy BIP rather than including proposals for both policy and consensus in the same BIP.

BIP-125 is I think an interesting case study. It is a much more fundamental standard than Ordinals or Taproot Assets, in the sense that transaction replacement is expected to be used by essentially all wallets as all wallets have to deal with fee-rate fluctuations; I do not think that Ordinals or Taproot assets are appropriate BIP material due to their niche use-case.

The V3 proposal, and ephemeral anchors, would be expected to be used by a wide range of contracting protocols, most notably lightning. This isn't quite as broad usage as BIP-124 RBF. But it is close. And yes, Core making changes to what is essentially BIP125 has an impact: just the other day I ran into someone that didn't know RBF Rule #6 existed, which Core added on top of BIP-125, and had made a mistake in their safety analysis of a protocol due to that.

Meanwhile, engineering documentation on V3 is extremely lacking, with basics like worked through use-case examples not being available. We don't even have solid agreement let alone documentation on how Lightning channels are meant to use V3 transactions and what the trade-offs are. And that has lead to mistaken claims, such as overstating(1) the benefit V3 transactions in their current form have for transaction pinning.

I don't think V3 necessarily needs a formal BIP. But it would benefit from a proper engineering process where use-cases are actually worked out and analyzed properly.

Finally, I think the lesson to be learned here is that mempool policy is better served by *living* documentation that gets updated to reflect the real world. There's no easy way for someone to get up to speed on what mempool policy is actually implemented, and more importantly, *why* it is implemented and what trade-offs were made to get there. It's quite possible that this "living documentation" requirement rules out the BIP process.

Having lived through y2k, two-digit years give me the ick, but otherwise sure.

Cheers, aj, that's how the kids who didn't live through y2k say it, right?

Hello,

First off, apologies about my lack of participation. I am working on mostly unrelated things and I'm afraid I have failed the community in terms of what I can do on my end to keep the BIP process functional.

As such I am hereby resigning as BIP editor effective immediately. Please remove my access privileges to the repository when possible.

-Kalle.

Thanks for this Peter, really helpful.

standard than Ordinals or Taproot Assets, in the sense that transaction replacement is expected to be used by essentially all wallets as all wallets have to deal with fee-rate fluctuations; I do not think that Ordinals or Taproot assets are appropriate BIP material due to their niche use-case.

Yes I'd personally lean towards this view too. Certainly when you go into alternative asset territory (e.g. Counterparty, Liquid (Network) assets, Taproot assets) it is moving away from what you can do with the Bitcoin asset/currency and into building a new ecosystem with a different asset/currency. I would agree that that should probably be out of scope for *Bitcoin* Improvement Proposals without having any particular opinion on the utility of any of those ecosystems.

that didn't know RBF Rule #6 existed, which Core added on top of BIP-125, and had made a mistake in their safety analysis of a protocol due to that.

I suspected this might be the case but to actually have a data point to back that up (beyond I personally find it unnecessarily confusing and hard to follow) is helpful, thanks.

served by *living* documentation that gets updated to reflect the real world. There's no easy way for someone to get up to speed on what mempool policy is actually implemented, and more importantly, *why* it is implemented and what trade-offs were made to get there. It's quite possible that this "living documentation" requirement rules out the BIP process.

I get the "living", evolving point. Policy proposals are definitely different to say consensus proposals where assuming they are ever activated you'd expect them to stay static for the rest of Bitcoin's existence barring minor cleanups, clarifications etc. However, one possible addition in a new BIP 3 process would be the introduction of versioning for a particular BIP e.g. BIP 789 version 2 which would be more conducive to these evolving proposals such as policy proposals. You could then update a BIP without needing a new BIP number for every material update.

I'll wait to hear what Luke thinks on this. Beyond the friction concern I think improving the BIP process for consensus and policy proposals would be the biggest potential win for a BIP 3 update.

Thanks also to Kalle too for his 18 month stint as a BIP editor :)
