A number of consensus-change proposals for bitcoin are on the desk for the time being. All of them have good motivations, whether or not it is scaling UTXO possession or making self-custody extra tractable. I received’t rehash them right here, you’re in all probability already acquainted. Some have been actively developed for years.
The previous two such adjustments which have been made to bitcoin efficiently, Segwit and Taproot, have been large engine-lift-style deployments fraught with drama. There have been smaller adjustments in bitcoin’s previous, just like the introduction of locktimes, however for some motive the final two have been kitchen sink affairs.
The truth not typically talked about by many bitcoin engineers is that up till Taproot, bitcoin’s consensus growth was kind of working beneath a benevolent dictatorship mannequin. Challenge management went from Satoshi to Gavin to… nicely, I’ll cease naming names.
Core builders will possible quibble with this characterization, however everyone knows deep down that to a primary order approximation that it’s mainly true. The “ultimate say” and large concepts have been implicitly signed off on by one man, or possibly a small oligarchy of wizened autists.
In some ways there’s actually nothing mistaken with this – most (all?) main open supply tasks function equally with fairly clear management constructions. Oftentimes they’ve benevolent dictators who simply “make the decision” in instances of high-dimensional ambiguity. Everybody is aware of Guido and Linus and the primarily based Christian sqlite man.
Bitcoin is aesthetically loath to this however the actuality, whether or not we prefer it or not, is that that is the way it labored up till about 2021.
On condition that, there are three components that create the CONSENSUS CONUNDRUM going through bitcoin proper now:
(1) The previous benevolent dictators (or high-caste oligarchy) have abdicated their energy, leaving a vacuum that shifts the mission from “typical mode of operation” to “novel, never-before-tried” mode: an try at some form of supposedly meritocratic leaderlessness.
This variation is coupled with the truth that
(2) the attainable design area for enhancements and issues to care about in bitcoin is large open at this level. Would you like vaults? Or extra L2s? What about rollups? Or how a few generic computational software like CAT? Or ought to we bundle the generic issues with purposes (CTV + VAULT) to verify they actually work?
The issue is that each one of those are legitimate opinions. All of them have advantage, each by way of what to give attention to and learn how to get to the tip objective. There actually isn’t a transparent “right” design sample.
(3) A ultimate issue that makes this example toxic is that faithfully pursuing, fleshing out, constructing, “doing the work” of presenting a proposal IS REALLY REALLY TIME CONSUMPTIVE AND MIND MELTING.
Getting the demos, specs, implementation, and “advertising and marketing” materials collectively is a protracted grind that takes years of expertise with Core to even strategy.
I used to be nicely paid to do that fulltime for years, and the method left me disgusted with the dysfunction and having little or no need to proceed contributing. I feel it is a frequent feeling.
A associated fable is that companies will do one thing analogous to assist the method. The concept that companies will construct on potential forks is fairly laughable. Most bitcoin firms have a ton on their backlog, are preventing for survival, and have mainly nobody devoted to R&D. The have a tough sufficient time integrating options that truly make it in.
Most of the ones who do have the price range for R&D are shitcoin factories that don’t care about bitcoin-specific upgrades.
I’ve labored for a number of the uncommon firms that care about bitcoin and do have the cash for this sort of R&D, and even then the sources usually are not adequate to construct a critical product demo on prime of 1 of N speculative softforks that will by no means occur.

This sort of scenario is why human techniques evolve management hierarchies. Basically, to progress in a scenario like this somebody must be able to say “alright, after due consideration we’re doing X.”
In fact what makes this appear intractable is that the Bitcoin mythology dictates (rightly) that clear management hierarchies are the way you wind up, within the restrict, with the Fed.
Certain, bitcoin can simply by no means change once more in any significant approach (“ossify”). However at this level that nearly definitely resigns it to yet one more monetary product that may solely be accessed with the advantage of a big establishment.
For those who grant that bitcoin ought to in all probability maintain tightening its guidelines for extra and higher performance, however that we should always go “gradual and regular,” I feel there are points with that too.
As a result of one other issue that isn’t talked about is that as bitcoin rises in worth, and as nation-states begin shopping for in measurement, the foundations will likely be tougher to alter. So inaction — not deciding — is definitely a really consequential determination.
I have no idea how this resolves.

There’s one other uncomfortable topic I wish to contact on: the place the facility really lies.
The present mechanism for altering bitcoin hinges on what Core builders will merge. This after all isn’t official coverage, nevertheless it’s the unintended actuality.
Different much less technically savvy actors (like miners and exchanges) have to select some indicator to concentrate to that tells them what adjustments are protected and when they’re coming. They’ve little capability or curiosity to measurement these items up for themselves, or do the event essential to determine them out.
My Core colleagues will bristle at this characterization. They’ll say “we’re simply janitors! we simply merge what has consensus!” They usually’re not being disingenuous in saying that. However they’re additionally not acknowledging that traditionally, that’s how consensus adjustments have operated.
That is one thing that everybody is aware of semi-consciously however doesn’t actually wish to personal.
Core devs saying “sure” and clicking merge has been a essential precursor each time. And proper now not one of the Core devs are taking note of the delicate fork conversations – type of comprehensible, there’s a bunch to do in bitcoin.
However let’s be sincere right here, a variety of the work taking place in Core has been type of secondary to bitcoin’s realization.
Mempool work is fascinating, however the entire mannequin is kind of the wrong way up anyway as a result of it’s primarily based on altruism. For-profit darkpools and accelerators appear inevitable to me, though that may very well be argued. A lot of the mempool work is rooted in assist for Lightning, which is fairly clearly not going to unravel the scaling downside.
Certain, encrypted P2P connections are nice, however what’s even the purpose if we are able to’t get on-chain possession to a degree past primarily requiring using an change, ecash mint, sidechain, or another trusted third social gathering?
My essential criticism is that Core has developed an ivory tower mindset that kind of sneers at folks piatching long-run consensus stuff as an alternative of making an attempt to really have interaction with the onerous issues.
And that would have bitcoin fall in need of its potential.

I don’t know what the answer to any of that is. I do know that self-custody is completely nervewracking and mainly out of the query for informal customers, and I do know that bitcoin in its present kind is not going to scale to twice-monthly quantity for even 10% of the US, not to mention many of the world.
The individuals who don’t acknowledge this, and who wish to spend important time and power wallowing within the mire of proposing the right remix of CTV, are making a fateful selection.
A lot of the longstanding, totally specified fork proposals lively immediately are completely fantastic, and conceptually they’d be nice additions to bitcoin.
Hell, in all probability the next block measurement is protected given options like compactblocks and assumeutxo and finally utreexo. However that’s one other put up for one more day.

I’ve gone forwards and backwards about writing a put up like this, as a result of I haven’t got any concrete prescriptions or suggestions. I suppose I can solely hope that citing these uncomfortable observations is a few distant precursor to creating progress on scaling self-custody.
All of those opinions have in all probability been expressed by @JeremyRubin years in the past in his weblog. I’m simply bored with biting my tongue.
Because of @rot13maxi and @MsHodl for suggestions on drafts of this.
It is a visitor put up by James O’Beirne. Opinions expressed are completely their very own and don’t essentially mirror these of BTC Inc or Bitcoin Journal.
