Matt Corallo 🟠@TheBlueMatt·
It’s time for bitcoiners to step up and build. You don’t need to know anything about software development anymore, you just need to know how to write words! We have a golden opportunity to build out agentic payments based on open money, rather than letting agentic payments be captured by megacorps yet again. But we’re squandering it arguing about useless crap instead of building. Play with openclaw, give it a bitcoin wallet (moneydevkit makes this super easy! Also Lexe and phoenixd!), make it do things. If it fails to do what you want, go fix it! Have your agent build that bitcoin domain reseller, that bitcoin airline ticket reseller, or whatever it is you want! Bitcoin doesn’t just happen, it’s built. Join in.

USDC on base seems far more common for 402 payments now than Bitcoin. Recently, even Stripe joined the bandwagon. That’s a centralized stablecoin on a permissioned chain. Agents are starting to use fiat. It’s a huge loss, and in a race, many aren’t even aware that it exists. The scam coins are marching on, and even fiat is evolving. Where are the Bitcoin solutions that attract real users? Which other concept other than buying and selling Bitcoin has actually broken out of the bubble and made it to the mainstream? Bitcoin doesn’t just happen. These missing solutions need to be built by someone. Reject the “Bitcoin wins by hodling” narrative. The devs and entrepreneurs are what keep this project alive and keep marching forward. It’s not the scammy influencers, not the psychotic drama queens, the child-like infighting, or incompetent idiots dancing on the graves of word-class devs leaving Bitcoin. I hope the bear market flushes all that crap away, and we can get back to building stuff instead of tearing it down.

@BtcCuracao @sethforprivacy @boyacaxa @cakewallet That is true, but the Spark operator can *also* take their keys (and with a past coin owner…which is also the Spark operator today) broadcast a claim transaction immediately which confirms before you get a chance to broadcast anything.

I'm assuming you know Spark better than me. I understood you always have a unilateral exit with Spark it's just that you have to broadcast a set of onchain transactions that precede your exit transaction which can be expensive in fees. The Spark Operator set can go down and all the VTXOs can get back onchain.

> Lightning is a 2-of-2 network. As is Spark. That's why Seth is saying self-custody. Lol, this is not true. In LN you *always* have the ability to broadcast a transaction and get all your money back, no matter what your peer does. There's requirements that you have to be online regularly to make sure you're safe, but that's it. On the other hand, with Spark, the operator can change the software they run and rug you. Period.

I respect both of you. Matt, self-custody has been used in crypto to mean the user has keys that control transfer of funds. USDT. Liquid BTC, WBTC. Lightning is a 2-of-2 network. As is Spark. That's why Seth is saying self-custody. Matt, your use of the word trust can be turned on numerous L1 Bitcoin wallets. Your logic could be used to say they aren't self-custody. I appreciate your nuance but respectfully disagree on which simple words are appropriate.

I’m back. Will be pushing on agentic bitcoin payments and building things agents will actually pay for. First step was getting @moneydevkit working on @Cloudflare. Required building a custom @lightningdevkit node that compiles to wasm to run on cloudflare’s js runtime and take advantage of their tcp, storage, and durable object apis. Source and examples here: github.com/johncantrell97… npm install mdk-cloudflare Just point your agent at the repo and will be able to get it running for you.

Yea I find it hilarious that people assume that anyone who doesn’t apply for a specific job must by definition not be qualified for it. I mean it’s easy to think that if you don’t think at all, but if you think for about five seconds it becomes painfully obvious this cannot possibly be true.

@securitybrahh I don’t believe any hardware wallet ever claimed it, so it still stands. Reach out to the coldcard folks first, of course, to make sure they’ll accept the patch.

Quick update on the software wallet side, *two* wallets have already stepped up and merged code that will claim the bounty! Given it was in less than ten days I'll be paying both of them out. That still leaves the bounty for hardware wallets, however. If you're a hardware wallet developer, now is a great time to dig into BIP 353. There's a few software wallets that will be including proofs for you, so its time to start validating and get the great UX benefit that comes with it!
Matt Corallo 🟠@TheBlueMatt

BIP 353 is a huge leap forward in security and UX for common payments from hardware wallets. Yet, sadly, it’s stuck in a three-way chicken-and-egg problem between the software wallets that people use, the hardware wallet firmware, and recipients. No one wants to do the work to be a first-mover when the other two legs don't exist yet. So, to get off zero, lets try a bounty. I'm offering $1000 (payable only in Bitcoin to a BIP 353 HRN) each for the first hardware wallet and (on-chain, hardware wallet-supporting) software wallet to support sending to BIP 353 HRNs. For a hardware wallet, this should be easy, just detect the PSBT field for a DNSSEC proof, validate it, and display the HRN for verification instead of (or in addition to) the actual address. You don't have to use docs.rs/dnssec-prover to do the validation, but I imagine it will be easy. The feature has to exist in the released default firmware for the hardware wallet. For a software wallet, there's only a few more steps, support detecting a BIP 353 HRN in the send-to UI, do the DNS lookup (again, dnssec-prover should make this easy, if you want), build the proof, and include it in the PSBT you provide to hardware wall ets. Also store the HRN (and maybe DNSSEC proof) so that the transaction history shows it. The default sending methods (GUI/CLI/whatever) have to support accepting HRNs and should handle them just like regular addresses. You don't have to support silent payments, but of course its good to as well. Support has to be in an official release. A hardware wallet that also provides a software wallet doesn't get to claim both bounties. Releases which satisfy the bounty must be made before December 31, 2025. If two software/hardware wallets claim the bounty the one which merged a substantial majority of the work gets the bounty, not just based on release date, otherwise it wouldn’t be fair to projects with a rigid release schedule.

Matt: At no point have I ever suggested, nor thought, that hiring decisions should consider anything but the above (intelligence, commitment, and history of contributions). Also Matt: "it’s worthwhile for companies and groups funding bitcoin core contributors (and indeed, any company hiring) to reach out to people that might otherwise not apply for a job or program and encourage them to." Also Matt: "It's long since time the bitcoin community spent a ton more effort on recruiting and ensuring underrepresented groups (incl women and especially folks with a different background) feel welcome in the community." Also Matt: "*the* most important aspect is setting the right culture of how things look going forward" Also Matt: "Explicitly encourage underrepresented groups to apply." The woke doublespeak is disturbing. Reality is, that if companies and gropups funding bitcoin core contributors focus on gender, "folks with different background", "underrepresented groups" when "reaching out to people", that is the very definition of considering other things than intelligence, commitment and history of contributions.

Valuable certainly, but “extremely valuable” to the point that he deserved jobs that others got? No. I know you (and he) have claimed that DEI is the reason other people might have gotten more funding/jobs/etc over him from several different organizations that claim is very wrong. From what I can tell there has never been a single hiring/funding decision in the history of the many companies funding Bitcoin Core contributors that considered anything except intelligence, commitment, and history of contributions. The other day you tried to claim that I suggested anything but that but that claim was also wrong. At no point have I ever suggested, nor thought, that hiring decisions should consider anything but the above. I have stated, and do think, that it’s worthwhile for companies and groups funding bitcoin core contributors (and indeed, any company hiring) to reach out to people that might otherwise not apply for a job or program and encourage them to. Lots of research shows that when you do that you end up increasing the intelligence/skill of the people you end up hiring, not decreasing it - more applicants means more people to choose from.

@ndeet @hodlonaut I mean for jobs they’re often in-person and generally come after quite some time of regular interaction. You find out alignment socially over time. And, yes, funders tend to be highly aligned - they’re donating millions of their hard-earned dollars to people to work on Bitcoin.

@TheBlueMatt @hodlonaut Thanks for the insights. Not sure how you can discover misalignment if people work on specific tasks and do them well. At some later point (years) they can still turn out not aligned at all? Also this assumes funders are even monitoring this and are aligned themselves.

Sure, but I’m not aware of any cases that. Instead the flow has typically been that people go through some kind of training program (where the top filter is skill, mostly) then after that they work on a grant (relatively low commitment for the funder) then eventually get hired. There’s lots of steps with increasing commitment from funders where those things can be discovered.

@TheBlueMatt @hodlonaut That said, I can see people first contributing for free may still turn out to be the wrong fit and not aligned (or an attacker) but training people on the job without self-motivation and understanding of Bitcoins purpose does seem to increase chance of picking the wrong candidate

That’s something you can (and should, and people do) interview for. As to your first question, there’s tons of research that many groups (women, etc) statistically only apply for jobs they’re overqualified for vs other groups (white men, etc) will apply for jobs they’re underqualified for. If you have a really great job, this effect can be worse (see-also the hot-woman problem in dating). Reaching out to people who might think “oh, I’m not quite qualified for that job” and encouraging them to apply has been shown many times improve the eventual outcome.

@TheBlueMatt @hodlonaut While that may widens the pool of possible applicants it also increases the chance to pick smart people that are good at what they are doing but are not aligned with why Bitcoin was created in the first place. Those are more likely fooled by crypto/shitcoin use-cases.

I intended to capture that with my reference to “commitment” in the hiring criteria I listed above. By that I, indeed, meant commitment to working on Bitcoin for what it is and understanding of the philosophical underpinnings of it. I do believe that is often an important hiring criteria, and certainly the hiring decisions I’ve been a part of have considered it.

No doubt that reaching out to people for jobs that they otherwise wouldn't be considered for can help raise their intelligence and skill. That doesn't mean it raises the level of what they're working on and can very easily have the opposite effect. Skill and talents are important for Bitcoin, but just as important, if not more so, is a firm understanding and appreciation for what it is and why it is. Rather than hiring somebody who thinks Bitcoiners are (or thought at the time were) nutty redneck carnivores, it probably would have been a much better plan to say "go spend 5,000 or 10,000 hours studying Bitcoin, history, anthropology, sociology, and economics, and maybe taxation and war. Then bring your technical skill set to Bitcoin with a humble appreciation for all of the other whys.

You are used to talking in insulated woke chambers, where truth is malleable according to the cultural politics and political correctness in place. It doesn't work here, Matt. My OP stands on its own. It doesn't need anything more. People can and will draw their own conclusions. People are not stupid. I'm sure your tactic of deflection has been very efficient for a long time though, congrats on that.

Hell, the thread you're making such a big deal about was about a Bitcoin training program (Jimmy Song's) where there was some effort to reach out to groups that might not otherwise apply and the net result was that the skill and intelligence of the participants went up! Just because they got more people to apply!

I guess you can't read? Please tell me where any of the quotes you listed said something about hiring decisions? Like I noted in the post you quoted, people should reach out to get *more* applicants for a job/program. That *increases* the talent pool and lets you hire a (potentially) even better candidate! Just because you get more people to apply doesn't mean you actively decide based on something other than talent.

Let's have a look at your dEbunKinG here: "No red carpet"? @jonatack was top-3 Core contributor globally by volume. His own words, on record from his presentation at PlanB Forum El Salvador: "The red carpet was rolled out for them and they got funding immediately, while the others who didn't fit the identity characteristics struggled very, very mightily." "OP_RETURN isn't used for spam"? Bitcoin Magazine, september 2023: "An interesting problem with Runes is that some transactions will break Bitcoin Core's 'standardness' rules by having OP_RETURNs that are larger than 80 bytes." Runes encodes all its protocol instructions in OP_RETURN. Casey Rodarmor, the creator of both Ordinals and Runes, basically the king of spam on Bitcoin says on his own development repo: oversized OP_RETURN transactions, frequently used by his Runes protocol, are already being accepted and mined by many miners with tools like Peter Todd's Libre Relay, and he predicts Bitcoin Core will eventually remove the 80-byte limit so they shouldn't worry about this limit. Here are the links: rumble.com/v75tyny-bitcoi… bitcoinmagazine.com/technical/roda… github.com/ordinals/ord/i… So... you are basically being straight up dishonest. Why is that?

When people talk about a once-in-a-lifetime trip, they often don’t realize that they may truly never return there. Many journeys that seem grand at the time eventually become ordinary parts of our lives. But even the little restaurant next to your home might, after some ordinary day, become a place you never visit again. Will space be once in a lifetime? I think not. But I really don’t know whether I will ever set foot on Bouvet again. I think Bouvet Island will very likely remain my true once-in-a-lifetime trip.
