Background on me:
I have spent 30 years in technology including nearly a decade as a product director at Google, a long-time angel investor, and most recently 6 years as the head of Block's Spiral initiative. My contributions to bitcoin include helping create Presidio Bitcoin, open source software projects including LDK, BDK and the BDK Foundation, and Stratum v2 reference implementation project, the bitcoin design community, the bitcoin consensus analysis project, COPA including defeating Craig Wright, Bitcoin Optech, ₿trust, Block’s mining business, and the PBJ show.
What questions would you like me to answer?
Latest news from Spiral? Is Lightning alive or dead? Am I completely crazy suggesting we ditch sats? What is Presidio Bitcoin up to? Should everyone immediately abandon Bitcoin Core? What is ₿product? Why did I become yet another podcaster?

What’s the biggest existential risk you see for Bitcoin that the ecosystem is currently underestimating, and how should we proactively build against it?
reply
Love your work, love your podcast.
What does the btc ecosystem need most that it doesn't have, or only weakly has? Define "ecosystem" at whatever scale you want.
reply
Thanks for the kind words.
I think the bitcoin ecosystem could use more proactive engagement on forward-looking design. Fast-forwarding to a future with a billion people using bitcoin as everyday money and what that could look like. Then working backwards from that vision and promoting design best practices to help us get there.

What is your biggest problem currently and what are your plans to solve it?
reply
If I may, I'll speak to 2:
  1. Mining centralization
  2. Making bitcoin everyday money
For 1, we're in a pretty bad state right now with 3 entities controlling nearly 90% of the hash rate, and 1 entity potentially flirting with 50% of the hash rate. We desperately need adoption of Stratum v2 to allow miners to select their own transactions. Longer term, I think the Braidpool project is promising. While still in the R&D stage, if it is successfully built, it can address the centralization risk that the FPPS mining pool payout method introduces.
As for making bitcoin everyday money, it is why I have worked in the space the past 7 years, and why I continue to work on it. While I fully embrace bitcoin as a store of value, I think that has already pretty much won. There isn't a lot of software and design improvements for it to succeed. Whereas, using bitcoin as everyday money has lots of software, design, and product work to be done. I think it is important because using bitcoin as everday money unlocks even more value for society and I think it strengthens bitcoin as a store of value as well.
Most of Spiral's focus is on solving these 2 issues.

does the Spiral team have any specific beliefs/hypotheses about how “bitcoin as everyday money” is likely to emerge? is the team mostly in agreement about these paths? does it require some amount of team/internal consensus to prioritize which projects to focus on?
reply
Which covenants proposal, if any, do you prefer?
reply
My view:
  • Generally an advocate for improving expressiveness including covenants
  • Slow & steady mindset. I don't believe there is some closing window of time we have to slip changes in.
  • In my mind there's a couple big differences between BIP54 and any covenants proposal. For one, BIP54 fixes consensus bugs and isn't adding new features. It should be able to more easily get consensus as long as the engineering is sound and well reviewed. Two, I'm not aware of 10 different competing proposals to fix those bugs. Whereas with covenants, there are a myriad of proposals all of which have pros and cons.
  • So I don't have a fav covenants proposal yet, but I do appreciate quite a bit of advancement in R&D over the past 4 years, so we have more proposals, each has matured, there's more mindshare on it. I'd like to see TXHASH mature a bit more. Perhaps it is the best solution?

Do you think after HyperBitcoinization the average user of Bitcoin will know or care what layer of Bitcoin (OnChain, Lightinging, Cashu,etc...) they are using on any given transaction?
reply
I'm a big proponent of "hide the lightning" and more generally "hide the technology behind making payments a great experience on bitcoin."
If you fast forward to the future, when bitcoin is used as everyday money, on-chain payments will be very infrequent. Payments are going to be made on a number of technologies which may include e-cash, Liquid, Spark, Ark, ZKP rollups, and of course LN, and of course LN will be the connective glue across all of these systems.
But end users don't need or want to know about all this complexity. They just want to see a bitcoin balance and to send and receive bitcoin.
reply
"hide the technology behind making payments a great experience on bitcoin."
Definitely. You can't think of educating billions of people about some technology before they start using it. Don't you think it would get easier and easier as the time passes? Like maybe one day we start having a preinstalled Lightning app on our phones or we have decentralised phones to make payments in Bitcoin.
reply
Yes I think it already has gotten much easier and this trend will only continue.
There will also be an explosion of bitcoin applications due to recent advances in bitcoin development tools and the emergence of vibe coding. The recent hackathon at Presidio Bitcoin resulted in a number of compelling applications being built in 24 hours, some of which were built by people who don't know how to code.

I didn't know you had a podcast now - cool! What's the elevator pitch for why folks should come check it out? What makes your show unique/different?
reply
Yeah you can find Presidio Bitcoin Jam, or PBJ, here https://www.youtube.com/@PresidioBitcoin
The elevator pitch is simple: "where bitcoin meets Silicon Valley." We don't have guests on the show. It is just the 3 co-hosts, all of whom have significant experience in Silicon Valley, but also very deep-rooted bitcoiners, discussing topics and news that pop up during the previous week, and layering in our questions and analysis. We hope to attract people from big tech to bitcoin, because we observe a big gap between what Silicon Valley thinks and understands about bitcoin compared to how bitcoiners think about bitcoin. We hope to close the gap! That said, I suspect bitcoiners will enjoy the show too because I'm not aware of another show that covers many of the topics we do in the way that we do.
reply
How do you see AI affecting bitcoin?
reply
  1. vibe coding is going to yield an explosion of new bitcoin applications. non-coders can now build new applications with bitcoin payments in literally less than 15 minutes. while most of the apps created will be poor quality and useless, what we will see is a lot of creativity and even just 1% of thousands of applications is a lot of quality ideas that can then be built out in a scalable, secure way. result: new ways for people to use bitcoin everyday.
  2. utilize LLMs for refactoring code, doing code reviews/audits
  3. somewhat the opposite of #2 - attackers will use AI to DoS attack repos by creating enormous volumes of open issues and PRs. They may try to sneak in back doors. Developing tools to combat this and enhance our already-highly-sensitive paranoia will be important.
reply
Great nym. Why did you choose it?
And yes you are completely crazy. Sats are the standard.
reply
I have the moneyball name on most services. Chose it way back in 2004 after having read the book.
₿ the standard. Make Sats bitcoin again ;-)
reply
No thanks. I will be continuing to call them sats regardless how people choose to display them.
Book was great. Movie was great. Moneyball changed baseball, not all for the better though.
reply
FWIW I totaly agree that "let the people call it what they wish." So if a product's UI shows "₿4,990" and you speak out loud or message to friends "4,990 sats" that's totally up to you.
reply
I agree with this!
reply
Great because that's what I and pretty much every other bitcoiner I know will do.
reply
That's fine but do recognize 0.001% of people aware of bitcoin are aware of sats.
Welcome to SN.
What are your views on Strategy?
reply
I like what Strategy has done to make buying and adopting bitcoin accessible to groups of people and capital that otherwise cannot be exposed to bitcoin. I hope Strategy begins to build useful products that makes bitcoin everyday money and that they fund open source bitcoin development.
reply
capital that otherwise cannot be exposed to bitcoin.
I wish more Bitcoiners thought the same about strategy. Anyways that's what I like about Strategy.
Is it the same reason you would also like BlackRock and Fidelity?
reply
Yes I also think BlackRock and Fidelity or good for bitcoin for similar reasons.
As with anything in bitcoin, we always need to monitor any single person or entity that gains too much power to make sure it does not become a threatening centralization point.
reply
make sure it does not become a threatening centralization point.
How?
You're now telling me you won't like them in future in case... What's a threatening centralisation point?
reply
I didn't say "I won't like them" I said that they merit monitoring. Just like my own company, Block, and even my small dev org, Spiral, merit monitoring. People in bitcoin should always be vigilant and ensure any naturally-forming centralization point does not grow too large.
The obvious centralization point of a BlackRock or Strategy is if they control millions of bitcoin. In the worst case scenario, bitcoin doesn't evolve into everyday money, the only use case is digital gold, and everyone just buys BlackRock's ETF fund or Strategy. Then all bitcoin is controlled by 2 companies...I think we all know where that ends. They would control the rules of bitcoin and could make changes that are antithetical to the principles of bitcoin.

What is ₿product?
reply
₿product is an unannounced new initiative. I guess I'll announce it here! Patterned after bitdevs, it will be a monthly meetup following Socratic seminar structure in which we'll discuss making bitcoin everyday money, apps and products in the space, and improving bitcoin design. The intended audience is application builders, product managers, designers, and anyone interested in making bitcoin usable every day.
We're going to start this at the Presidio Bitcoin in San Francisco. We'll meet the 4th Thursday of every month, beginning June 26. Eventually, I'd love to see this adopted in cities around the world, much like bitdevs has.
reply
That's cool, is something similar to what the Bitcoin Product Community is doing?

I'm not aware of much activity in that discord server in the past year or so. But this idea is independent of that - AFAIK they never had in-person meetups.

What are the latest scoops that make you think so?
reply
LN payment volume continues grows 15-20% per month. Block earns 10% return on capital - in bitcoin terms - with their LN node. And LN has already won the rails race between all the different systems wallets use and will use to reach users (Cashu, Fedimint, Ark, Spark, Liquid, etc. all require LN to make payments).

I can't believe the 10% revenue on liquidity, specially since I saw that this is supposedly just routing not lsp-ing cashapp. Even so it seems absurd given the public fee structure and how much volume you'd have to have to reach that. Can you convince me that its actually real?
reply
The fees are public. Let's say the fees are 1 basis point. How many ₿X payments per year would a node need to forward to generate a 10% return on ₿X capital?

What's your bullishness rating on Nostr long-term? How will Spiral play a role in Nostr's growth and adoption?
reply
I'm a supporter of nostr. I'd call myself mildly bullish. I'm definitely glad it exists and that there is energy devoted to it. I view its prospects more positively when viewed as a permissionless content protocol and as a development tool vs. viewing it as a "Twitter clone."
Spiral doesn't provide direct support for nostr but that is solely a focus reason not an opinion on its value.

You recently stated that SV2 benefits everyone while DATUM only benefits a single VC-backed startup. How is that true when SV2 and DATUM are both published under the exact same FOSS MIT license?
From my perspective, OCEAN should be lauded, not criticized, for their efforts to improve Bitcoin for everyone by releasing their software free to the world.
Aside from the licensing topic, can you provide your technical assessment of the pros/cons between SV2 and DATUM? Which user groups are better suited for each?
reply
  1. SV2 has had broad industry contribution with funding or development from Foundry, Braiins, Galaxy, Hut8, Block, Spiral, and Blockstream. It is a true public good that isn't dependent upon a single company.
  2. My understanding is that DATUM is closed source on the pool side. If Ocean's DATUM pool is open source, it'd be great if someone could post a link to it.
I do laud Ocean's intended goal of decentralization. My criticism of it is that they didn't introduce anything novel with DATUM, which functionality-wise is a subset of SV2, which already existed prior to Ocean. The Ocean team "doesn't like Rust" and also demonstrated a lack of understanding of what SV2 even is, which seems to have led them to a path of creating their own version.
I'm skeptical other pools are going to adopt DATUM. Worse, Antpool just announced a new decentralized mining pool solution. Details haven't been shared, but I worried it will be yet-another protocol. Competition is good in general, but in this case, if each pool has their own "protocol for decentralization" it defeats the intended purpose. Instead, it will create even more vendor lock-in as miners would have increased switching costs between pools. Therefore, it is very important for miners to adopt a single protocol standard that has widespread support in the industry.

What’s the most surprising thing you’ve learned running spiral? What’s the hardest part? What’s your favorite part?
reply
Despite having years of software experience under my belt knowing that things always take longer than expected, I remain surprised at how much longer it takes to get things done in bitcoin due to (a) being a protocol (b) being more decentralized than anything else. Having patience for that is the hard part.
My favorite part though is still how much progress so many people can make by building on top of the protocols. It is satisfying to see how much more usable bitcoin is today than 6 years ago, and I cannot wait to see what it looks like 6 years from now.
