We’ve Got A Problem
Decentralized consensus isn’t straightforward. There’s a motive most firms have CEOs, and “non-hierarchical” organizations have a tendency not to perform nicely for lengthy. Bitcoin’s decentralized governance is tougher nonetheless: On high of decentralization, we layer a relative lack of official processes, requirements and norms for group decision-making — we even lack readability round when to decide in any respect.
Jeremy Rubin’s latest proposal of a Speedy Trial consideration for Bitcoin enchancment proposal (BIP)119 (OP_CTV) has introduced these points to the fore, illustrating simply how tough and amorphous the Bitcoin decision-making course of is.
This drawback is largely inevitable. Bitcoin wouldn’t be Bitcoin with central governance. But because the group scales and turns into extra ideologically various, this drawback will get worse and efficient communication and decision-making turn into more and more tough.
This article argues for 2 adjustments to the “meta” technique of BIP consideration, which I consider might considerably enhance the standard of our debates:
- Raise a set of excessive requirements for BIP documentation.
- Adopt these open requirements as a de facto minimal high quality bar for a BIP to be thought of for wider dialogue.
I consider these requirements might radically enhance the standard of our decentralized decision-making about Bitcoin. But first, I’d like to illustrate the issue in additional element.
Information And objectivity
Let’s decide on an nameless, extremely indicative tweet:
“CTV isn’t necessary and is very much in its infancy as a project. No one knows enough about it, no one has bothered to review it thoroughly. I’m not a developer or technically trained but this feels rushed and that is a 🚩 for me.”
The claims made on this tweet exemplify two broad issues I see with the dialogue about CTV: poor informational requirements and unmoored subjectivity.
Poor Informational Standards
Our anon argues that CTV is “very much in its infancy as a project,” however by affordable or comparative requirements, this is not true. CTV was beneath growth in 2019. Its BIP quantity was assigned over two years ago and constant work has been accomplished on high of the basically static BIP since. Its potential purposes have been explored within the programming language and graphical user interface that its writer constructed to create, visualize and check covenants — together with different BIPs.
“[N]o one has bothered to review it thoroughly,” the anon provides, however a lot of Bitcoiners and builders have accomplished so. The social “signals” of their help or objection are listed on Rubin’s CTV web site, the place he additionally hyperlinks to implementations of numerous downstream uses of CTV by himself and others.
The writer of mentioned tweet has an affordable mannequin for decision-making — to oppose new or poorly reviewed proposals — however is making use of that mannequin incorrectly as a result of he lacks important context.
The above two criticisms are not the one standard expressions of this drawback. For instance, considerations have been voiced about CTV’s riskiness, however they are voiced within the absence of important context — readability round what constitutes a danger and comparability to beforehand accepted BIPs.
By manner of context, Taproot, a far riskier proposal in virtually each manner — with advanced cryptography doubtlessly topic to future quantum assault and a considerably larger footprint of code to debug and keep — appeared to sail by means of with comparatively little testing and scrutiny, causing bugs, losing funds and involving incompletely demonstrated applications.
(My argument is not, “Because Taproot, therefore CTV.” I’m merely pointing to the inconsistency ensuing from a poorly knowledgeable psychological mannequin.)
Most of us work for a residing and maintaining with these items is exhausting. Epistemic constraint is a elementary reality of human existence. But to amend a quote by Thomas Jefferson, “An educated citizenry is a vital requisite for Bitcoin’s survival as the global monetary standard.”
The dialogue about BIP119 may gain advantage from a a lot larger flooring of understanding and context.
Unmoored Subjectivity
Our Twitter anon makes two additional factors: “CTV isn’t necessary” and “[T]his feels rushed and that is a 🚩 for me.” Once once more, the arguments are honest sufficient. As Rubin himself mentioned, pointing to alternate covenant options, “I don’t give a single fuck if BIP-119 CTV specifically is activated or not.”
But these two statements level squarely at one other drawback with the talk: Our unavoidably subjective requirements don’t have anything tangible to latch onto — no goal measures and no clear comparisons. In the absence of clear and comparative proof, how are we to assess what is “necessary” or has been “rushed” with out resorting to emotion, group-think and shifting, illogical argumentation?
“Eternal toxicity” may be “the price of consensus,” and subjectivity is elementary and unavoidable. Permanent subjectivity indifferent from related info, nonetheless, destroys the capability for collective decision-making.
What To Do About It?
I suggest the adoption of a set of public documentation requirements for what constitutes the naked minimal a BIP should present to be worthy of large-scale public debate. I’m not advocating for a transparent path to BIP acceptance and even to BIP dialogue. I’m advocating for the next normative commonplace of public documentation with out which we will agree to take into account a BIP “rushed,” “too early” and “very much in its infancy as a project.”
In a phrase, “The community will consider your BIP premature until it answers all the relevant questions clearly in one place.”
I see two important advantages to this larger bar: It anchors the inevitably subjective debate to constant goal measures and it raises a normal for documentation possible to lead to better-informed dialogue.
Absent the readability to meaningfully align on the comparative requirements for a given BIP, our decentralized debates descend right into a purgatory of “trivial” bikeshedding — a hippie co-op from hell.
The implications of this are lethal severe. As our group grows in scale, distribution and mental range, we very critically danger changing into a contemporary Tower of Babel, an bold challenge that falls into disarray due to a elementary incapacity to productively talk and make clever collective selections.
This is as chill because it’ll get. We’re gonna want a greater course of. There are causes to be cautious of extra processes, nonetheless, and I believe it’s essential to deal with them first.
Objections
On Ossification
My argument assumes the desirability of change in any respect. Many locally argue in opposition to any change and for “ossification” of Bitcoin’s code, however even when we would like to defend Bitcoin because it is, I consider this to be a mistake.
Bitcoin’s worth lies in sure elementary properties. Some of these properties require efficient code stasis. The mining rewards imposing the availability cap set in place by Satoshi — peace be upon him — present the canonical instance.
Other core properties of Bitcoin, nonetheless, are dynamic capabilities of the broader setting, in addition to of Bitcoin’s utilization over time. These can change even when Bitcoin Core’s code doesn’t.
Consider privateness. Bitcoin’s ledger is dismayingly open to chain analysis. Privacy advocates worry that bitcoin’s elementary lack of default privateness opens it up to assaults that would remove fungibility and make the forex virtually unusable for something aside from condoned, tracked and taxed functions — a central financial institution digital forex (CBDC) by proxy.
Privacy is not the one irreducible monad of bitcoin’s worth proposition. Rubin’s advent calendar series of articles on covenants outlines an affordable beginning set of 4 such “pillars” past its constrained provide:
- Scalability: The capability for bitcoin to be utilized by a large set of individuals, not merely function the financial layer for financial institution and company remaining settlement.
- Self-custody: The capability for people in quite a lot of areas and circumstances to simply safe their personal funds, quite than depend on third events (who can seize their funds or mint “paper bitcoin”).
- Decentralization – The dispersal of energy throughout a variety of actors, itself a proxy for elementary censorship-resistance and person management.
- Privacy – The ease with which bitcoin customers can transact with out their funds being tracked, seized, marked or blocked.
Perhaps you don’t actually care about one or two of those “pillars.” Perhaps you need to add one other of your personal. But take into account the next checklist and notice how:
- For most Bitcoiners, some traits aside from auditability and stuck issuance are extremely beneficial.
- Each of those elementary values is a spectrum, all with important room for enchancment.
- Functionality which is prohibitively tough to use — or which depends on a trusted custodial service performing off-chain — is a far cry from performance which might be trustlessly executed with Bitcoin script.
- Bitcoin’s “rating” alongside these axes shifts naturally over time, as when China bans miners, chain evaluation turns into extra Orwellian, charges shoot up or down or UTXO area turns into too scarce for world use.
- The “rating” for every pillar improves as extra Bitcoiners enhance their particular person standing, as when extra widespread non-public use will increase the fungibility of bitcoin as an entire, or widespread self-custody limits exchanges’ capability to fractionally reserve it and manipulate the worth.
A 21-million hard-capped forex which can’t be accepted by any distributors — which is onerous to self-custody and stays predominantly in un-auditable company-held “paper bitcoin” accounts, or which can’t scale to be utilized by most individuals on the planet (Lightning Network is not a singular reply right here) — will possible fail in its core mission of worldwide emancipation from the horrors of a centrally managed, inflationary forex.
In different phrases, code ossification can imply the erosion of Bitcoin’s core strengths.
Bitcoin’s adversaries are consistently bettering, and as Lightning Labs CTO Olaoluwa Osuntokun put it in a recent TFTC interview, we’d like to consistently degree Bitcoin up for its “next big boss,” since there are no “respawns” in Bitcoin.
We can’t simply sit again, complacent in our citadels, and watch Bitcoin nail the moon touchdown. Not code ossification, however ossification round a set of ideas, together with strict requirements for the adjustments obligatory to hold us on observe, ought to be our purpose.
Even in the event you disagree, you possible agree that change will, maybe sadly, proceed to happen. In a manner, the query is whether or not that change meets excessive, public and well-communicated requirements, together with requirements of stasis in important methods, or if that change is pushed in relative non-public with out assurances of high quality. Again, this drawback turns into more and more tough with time.
On Murkiness
There are many locally who really feel the shortage of readability within the BIP course of is optimistic. Their argument is very a lot price contemplating.
In a recent newsletter, Marty Bent refers to this attribute as “murkiness,” and he argues that “murky rough consensus driving protocol changes” is higher than “a well defined process that could potentially be socially attacked.” Defending core builders’ reluctance to make clear a course of for BIP proposals, Marty argues that “those who have the keys to the machine that allows you to change the most commonly used client should be as impartial as humanly possible.”
This argument is sensible. Consider it by analogy: Knowledge of the exact equipment or protocols utilized in elections permits hackers or social engineers to extra simply sport them, however as safety specialists have was a chorus, “security by obscurity” is restricted in its efficacy, and has important drawbacks. More importantly, the argument for common murkiness implies that each one types of readability are equally possible to present angles of assault and equally unlikely to add worth.
A totally different analogy, of an engineering job software, makes clear that there are many various types of “clarity” and “murkiness,” and they enact totally different trade-offs:
- An employer would possibly publish the questions they plan to ask in an interview. This would permit candidates to put together “for the test” and undermine the worth of testing. Lower high quality staff would end result.
- An employer might need questions however not publish them. This encourages insiders like recruiters to share the questions with their shoppers, thereby making a secret benefit and legitimately gaming the method. Lower high quality staff with “political” connections would end result.
- An employer would possibly increase clear public requirements for candidates. For instance, every applicant should exhibit 4 years of related expertise in a resume that displays effort and group. Higher high quality staff would usually end result, with out skewing outcomes politically.
If the requirements are fairly chosen, this final choice does little however enhance the standard of the interplay, saving employer and applicant time and bettering common high quality. Furthermore, the totally murky course of usually advocated for Bitcoin is extra akin to a job software the place the questions can’t be gamed as a result of there are none (as a result of there is no constant commonplace), and every applicant is judged arbitrarily primarily based on the temper and people of the day.
This factors to two further points:
- An arbitrary course of invitations inconsistency and even corruption. Ivy League colleges can leverage unspecified and arbitrary requirements to settle for “well-rounded” kids of Hollywood stars or cash-cow legacies as a result of “unspecified” is not “unknowable” or “incorruptible.” As Rubin famous on the bitcoin-devs mailing checklist, “the amount of work a BIP needs to do … to fully describe all applications and use cases” is unclear. In this current circumstance, centralized, arbitrary gatekeeping appears to outline the road of “enough” for broader dialogue.
- Social belief is a short-term resolution. We could belief the Core builders of at the moment to make selfless and smart arbitrations. But Bitcoin ought to stay strong for ages, and trusted third events are safety holes. Moreover, because the final two years have made clear, leaning on centralized “experts” leads to technocracy, and the corrosion and seize of the skilled class itself.
I’m arguing for the equal of a resume commonplace to increase the bar for an entrant to dialogue with out setting any clear or gameable path for acceptance. It appears clear to me that this is not a safety danger, but it surely is a contribution to the standard of purposes and dialogue.
It is for the same motive {that a} BIP course of exists in any respect. Only probably the most totally examined and explicated BIPs ought to be thought of for activation and the group ought to be maximally geared up to productively talk about them.
The Proposal
A guide (BIP2) exists for the proposal and creation of a slender BIP “technical specification” doc, however past that, there appears to be no commonplace for figuring out what is a “good” or “complete” BIP.
It is essential for the long-term well being of Bitcoin that its group coalesce round a extra strong set of public requirements to which we will maintain future BIPs. These requirements ought to be maximally quantitative and deal with the total vary of questions and considerations Bitcoiners might need a few proposal in as digestible and goal a fashion as potential.
As a linked complement to the BIP doc, every BIP ought to be accompanied by a residing artifact which addresses all the necessities under, making a single navigable repository of ongoing, version-controlled details about the proposal.
Let’s name it a “proposal tracker” — a primary step for anybody wanting to perceive and take part meaningfully in debate. Each proposal tracker ought to have sections on: historical past, description, assets, prices and dangers, advantages, options, activation and a autopsy.
History
To apply quantitative heft to considerations {that a} given BIP “feels rushed,” the proposal tracker ought to embody a full timeline of related occasions:
- Date first proposed: Date concept was first introduced up on the Bitcoin mailing checklist.
- Date of BIP: When it was given an official BIP quantity.
- Changelog
- Discussion log: Dated hyperlinks to references in Bitcoin mailing lists or different public fora.
- Review log: For every reviewer, their date of overview and the substance of their overview.
Some of this data is already out there for individuals who need to spelunk in BIP commit historical past, however a future which requires each Bitcoiner to use GitHub to be told is not a future during which good selections are made.
Description
For The Nerds
A hyperlink to the BIP we see at the moment: The condensed, technical proposal with actual implementation particulars and references to concrete opcodes, fields and code.
For The Five-Year-Old Plebs
Not everybody who is invested in Bitcoin’s future has the time or capability to parse by means of the technical particulars of a proposed change.
Each proposal tracker ought to embody a high-level clarification that anybody who has learn The “Bitcoin Standard” (okay, perhaps “Inventing Bitcoin”) can grok. What does this BIP purpose to do and the way does it do it, broadly talking? What, at a excessive degree, are its prices and advantages? Maybe Lily can clarify.
To have interaction in knowledgeable debate, the group wants to be … knowledgeable. Although a distributed group of journalists, podcasters and lovers goes a great distance, a collaboratively edited description for the layperson would considerably add to public understanding of the BIP.

Costs And Risks
The Bitcoin group appears fairly alive to the dangers of change, however usually in a imprecise manner that reveals little conception of the specific risks posed by a specific change. The dangers of a given proposal to Bitcoin Core (and they are numerous) ought to be listed explicitly. They embody:
- Protocol safety danger: For instance, does new cryptography add a danger of compromise by future quantum computing?
- Maintenance price: How sophisticated will this code be to keep, yr after yr, for the size of Bitcoin’s existence? Perhaps traces of code might be one measure of this price together with dialogue of shortage of related experience and inherent complexity.
- Other complexity prices: Will this be exhausting for non-Bitcoin Core software program to implement? Is this tough to check?
- Footgun danger: Does this alteration enhance the probabilities of a Bitcoiner doing one thing silly with their cash? Is it exhausting to use appropriately?
- Political danger: Does this alteration add any floor for presidency assault? For instance, some concern has been expressed that covenants might be used by governments to constrain bitcoin uses. Are there smart responses to such concerns?
- Computing price: Does computation of the brand new opcode add important time to node transaction processing or blockchain parsing?
- Space price: Does this enhance the scale of blocks or transactions, rising node {hardware} necessities and minimizing decentralization?
- Non-pareto adjustments: Does this addition undermine the power of any of the “core pillars” of Bitcoin?
- Deployment danger: Do present nodes and wallets encounter blocks, transactions or addresses that they don’t perceive? If miners don’t improve however declare to have upgraded, how is safety diminished?
- Developer confusion: If this alteration rolls out, will the same change that has some higher qualities get rejected as insufficiently helpful?
Beyond the above non-exhaustive checklist, every proposal ought to embody a dialogue of interactions with different proposals being thought of. How does this explicit BIP work together with different BIPs on provide? Rubin’s aforementioned “advent calendar” makes an attempt to explore these interactions and future proposals ought to observe go well with — ideally in a transparent, well-formatted method akin to a easy desk accompanied by an evidence.
A long-running bug bounty, akin to that on offer for CTV, is strongly inspired and might be community-sponsored sooner or later.
Benefits
Solo
What are the implications and purposes of this proposed change by itself? What does it make potential? What does it make simpler? Each described “application” ought to embody:
- A layperson clarification: How does this BIP make an software potential? For instance, what is the fundamental logic by which BIP119, which tightly constrains how an output could also be spent, makes “smart vaults” potential?
- A technical clarification: On a degree nearer to pseudocode, what is occurring with the code to make this software potential?
- A technical implementation: Tested code, ideally illustrated in Sapio or another explorable/vettable “playground.”
- Discussion of diploma of resolution: Does the BIP make this software potential or simply simpler, clearer or extra environment friendly?
- Relevant pillar: Using Rubin’s above taxonomy or another system of worth, what elementary purpose of Bitcoin’s does this software deal with? Does it make it extra scalable, straightforward to custody, censorship-resistant or non-public?
- Urgency and stakeholders: What teams does this add worth to and the way a lot worth? Does it deal with an especially pressing challenge?
Combined
Since BIPs are usually constructed as “small steps” quite than “big leaps,” they are usually designed to turn into extra highly effective along with future proposals. What might be achieved together with future BIPs? (Note the dialogue of combinatory danger above.)
All of the above necessities for “solo” purposes ought to apply right here as nicely, minus the technical implementation, which relies on the opposite BIP’s degree of progress.
These necessities increase a excessive and costly bar for any proposal — which is the concept. Ideally, a totally etched-out sense of each prices and advantages will allow extra Bitcoiners to type correct assessments of the risk-benefit ratio of a given change.
Alternatives
BIP119 is a covenant and has some overlap with different covenants. Each proposal tracker ought to attempt to sort out the query of “why this proposal” and never others prefer it. How does it match into the ecosystem of different BIPs?
Activation
How do the authors suggest activating this BIP and why? What is their splendid schedule and their fallback plan? Should activation precede merging into Bitcoin Core? Should it ever not? Ideally, over time, the Bitcoin group can arrive at some preemptive consensus round which activation strategies are splendid primarily based on governance options and a balance of powers.
Post-Mortem
If the BIP turns into a part of Bitcoin Core, the writer or authorial group ought to observe its integration over the approaching months and years. What labored and didn’t work? Was the method profitable? Was the method incomplete?
If rejected, what classes have been realized?
Where To Go From Here?
Much rigor and measurement might be added to the above, however I hope it’s a helpful begin.
We will be taught from this course of. Perhaps we’ll discover that CTV meets these minimal necessities, however isn’t pressing or highly effective sufficient to embody in Bitcoin Core. Perhaps we’ll uncover, to our dismay, that Taproot confronted a a lot simpler commonplace and was even “rushed” in “its infancy.” Regardless, we should always uncover an affordable baseline for overview, clarification and testing. By making use of a extra constant and documented course of, we increase the standard of each proposals and debates.
The Bitcoin group’s concentrate on defending its fundamentals from change is important, however this adversarial posture is principally outward-facing and might miss refined threats from inside. If we are unable to deal with debate with out descending into aimless factionalism, we could fail to deal with the broader utilization and larger political stress coming our manner.
Decentralized consensus isn’t straightforward. We ought to take it very critically.
