A variety 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 huge 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 cause the final two have been kitchen sink affairs.
The truth not usually talked about by many bitcoin engineers is that up till Taproot, bitcoin’s consensus growth was roughly working beneath a benevolent dictatorship mannequin. Challenge management went from Satoshi to Gavin to… nicely, I’ll cease naming names.
Core builders will probably quibble with this characterization, however everyone knows deep down that to a primary order approximation that it’s mainly true. The “last say” and massive 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 flawed with this – most (all?) main open supply initiatives function equally with fairly clear management buildings. Oftentimes they’ve benevolent dictators who simply “make the decision” in occasions of high-dimensional ambiguity. Everybody is aware of Guido and Linus and the based mostly 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(1) The outdated benevolent dictators (or high-caste oligarchy) have abdicated their energy, leaving a vacuum that shifts the undertaking from “typical mode of operation” to “novel, never-before-tried” mode: an try at some sort of supposedly meritocratic leaderlessness.
This transformation is coupled with the truth that
(2) the doable design house for enhancements and issues to care about in bitcoin is extensive 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 ensure they actually work?
The issue is that every one of those are legitimate opinions. All of them have advantage, each by way of what to concentrate on and get to the top aim. There actually isn’t a transparent “appropriate” design sample.
(3) A last issue that makes this case 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 an extended grind that takes years of expertise with Core to even method.
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 want to proceed contributing. I believe this can be a frequent feeling.
A associated fantasy is that companies will do one thing analogous to assist the method. The concept companies will construct on potential forks is fairly laughable. Most bitcoin firms have a ton on their backlog, are combating for survival, and have mainly nobody devoted to R&D. The have a tough sufficient time integrating options that really make it in.
Lots of the ones who do have the finances for R&D are shitcoin factories that don’t care about bitcoin-specific upgrades.
I’ve labored for a few of the uncommon firms that care about bitcoin and do have the cash for this type of R&D, and even then the sources will not be enough to construct a critical product demo on prime of 1 of N speculative softforks that will by no means occur.

This sort of state of affairs is why human techniques evolve management hierarchies. On the whole, to progress in a state of affairs like this somebody must be able to say “alright, after due consideration we’re doing X.”
After all 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.
Positive, bitcoin can simply by no means change once more in any significant means (“ossify”). However at this level that nearly definitely resigns it to yet one more monetary product that may solely be accessed with the good thing about a big establishment.
In case you grant that bitcoin ought to in all probability hold tightening its guidelines for extra and higher performance, however that we should always go “gradual and regular,” I believe 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 principles shall 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 need to contact on: the place the ability really lies.
The present mechanism for altering bitcoin hinges on what Core builders will merge. This in fact isn’t official coverage, however it’s the unintended actuality.
Different much less technically savvy actors (like miners and exchanges) have to choose 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 this stuff 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!” And so they’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 need to personal.
Core devs saying “sure” and clicking merge has been a mandatory precursor each time. And proper now not one of the Core devs are taking note of the tender fork conversations – type of comprehensible, there’s a bunch to do in bitcoin.
However let’s be trustworthy right here, lots of the work occurring in Core has been type of secondary to bitcoin’s realization.
Mempool work is attention-grabbing, however the entire mannequin is kind of the other way up anyway as a result of it’s based mostly on altruism. For-profit darkpools and accelerators appear inevitable to me, though that might be argued. A lot of the mempool work is rooted in assist for Lightning, which is fairly clearly not going to resolve the scaling drawback.
Positive, encrypted P2P connections are nice, however what’s even the purpose if we are able to’t get on-chain possession to a stage past basically requiring using an alternate, ecash mint, sidechain, or another trusted third occasion?
My principal criticism is that Core has developed an ivory tower mindset that roughly sneers at folks piatching long-run consensus stuff as a substitute of making an attempt to really interact with the laborious issues.
And that might 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 need to spend crucial time and vitality wallowing within the mire of proposing the right remix of CTV, are making a fateful alternative.
A lot of the longstanding, totally specified fork proposals lively at this time are completely effective, 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 ultimately utreexo. However that’s one other publish for one more day.

I’ve gone forwards and backwards about writing a publish like this, as a result of I haven’t got any concrete prescriptions or suggestions. I assume I can solely hope that mentioning 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 uninterested in biting my tongue.
Due to @rot13maxi and @MsHodl for suggestions on drafts of this.
This can be a visitor publish by James O’Beirne. Opinions expressed are solely their very own and don’t essentially mirror these of BTC Inc or Bitcoin Journal.
