Huge milestone for Cashu. After 3 years of work, we finally have unruggable mints. I'm testing the first on-chain Cashu mint running inside a Trusted Execution Environment (TEE), where the mint keys are generated entirely within the enclave and remain unknown to the operator. That means the operator cannot inflate the ecash supply and cannot access the Bitcoin reserves backing it. We've moved from trusting operators to relying on hardware-enforced cryptographic guarantees. There's still work to do, but the path forward is clear. This is an incredibly exciting step toward trust-minimized ecash.

The feeling when you print 40% of all dollars in existence and your term ends before the bubble pops.

we want bitcoin to be everyday money asap

So Robin was correct the whole time. Noted.

There's no problem here. This is the transition that AI needs and miners needed too. Mining will continue wherever there's waste. Wherever there's a need for heat expensive gas cheap electricity, mining will flourish. There WAS a problem, mostly caused by the fiat side. This is a return to sanity. Bitcoin mining is not an apex predator of energy. It's a bottom feeder.

Big fan of your work Jon, for like 20 years. But you could find better guests on this topic. More nuanced.

An open letter to @ProfSteveKeen regarding your recent comments about Bitcoin and Bitcoin mining. Respectfully, I have listened to your comments on Bitcoin mining and it is very clear that you have no understanding of how Bitcoin mining works. This is not a hill you I believe you should be seeing your reputation die on. Specifically it is very clear that you have no understanding that it is a flexible user of energy that does not rival other energy users for its power, no understanding of the well established ability Bitcoin mining uniquely has to monetize otherwise wasted renewable energy, no understanding of how Bitcoin mining obviates gas peaker plants, and no understanding of the unique role Bitcoin mining is playing in methane mitigation. You also appear not to understand that these facts are not some pot pouri of greenwashing claims from "Bitcoin supporters" looking to defend their assetclass but datapoints that have been repeatedly established in 24 peer reviewed journals, and 8 independent reports (including Cambridge University) Your characterization of Bitcoin supporters as not understanding the interrelationship between global warming and energy dynamics is as patronizing as it is a reconfirmation of your own lack of research, given there are a number of committed environmentalists, climatetech investors and climate scientists who are avid supporters of Bitcoin mining precisely because it already can and is incentivizing renewable energy transition and methane mitigation at scale. You also appear ignorant of the fact that the first generation research on Bitcoin mining that suggested environmental harm was debunked in peer reviewed study in 2023 and that is why the media has not quoted this study since. Finally your contention that Bitcoin is "going to zero" because mining will become unprofitable shows again an appalling lack of basic understanding of the economics of Bitcoin mining. Bitcoin mining companies are able to earn ancillary revenue through any number of means, they may be vertically integrated, they may mine using last-gen machines on stranded solar/wind, they may mine offgrid on otherwise wasted power sources such as landfills of oil&gas fields, they may be nation states such as Bhutan using Bitcoin mining on their otherwise surplus hydro energy. These unique abilities of Bitcoin miners mean that far from being at risk, Bitcoin mining is by far the most resilience industry in the face of rising energy prices. The mere fact that Bitcoin mining exists and is growing in EU despite already very high energy prices is proof of Bitcoin miners' resilience to rising energy costs that affect other industries far more. Your opposition to Bitcoin, and Bitcoin mining, appears more motivated by regret aversion, a well documented psychological phenomenon where someone who "misses out" rationalizes that "there was nothing to miss out on" rather than engage in genuine intellectual curiosity and humility by revisiting their decision, and this is leading you to invest an inordinately large amount of time dismissing a technology you have made an inordinately small amount of time trying to understand. When someone of your standing in the field of economics talks so dismissively about a domain they have spent so little time seeking to understand, it does not weaken that domain, rather it weakened 1. your reputation 2. people's general trust in economists 3. the extend to which we esteem people in society with the title "professor" If you want to continue to erode the reputation of all three, you are welcome to do so. Bitcoin does not care. Bitcoin miners will continue to stabilize grids, monetize wasted renewable energy, mitigate methane, obviate the need for gas peaker plants with or without you. But if you ever decide to re-allocate a small fraction of the hours you have spend dismissing Bitcoin mining into understanding how the technology works that you are dismissing, I would be more than happy to connect you to any number of utilities, renewable energy experts, methane mitigation specialists, climate scientists, climatetech investors or battery engineers who can explain to you why Bitcoin is an essential part of solving the exact issues you claim to care about.

@brian_armstrong dude: we need no taxes on bitcoin, never mind de-minimis.

Remember that I predicted a long time ago that President Obama will attack Iran because of his inability to negotiate properly-not skilled!

I'd like to learn who is actually behind this global push for "age verification" and digital ID. Why is no journalist writing about this?

Imagine thinking that having a certificate that represents company shares counts as self custody in the same vein as holding a gold coin or a private key. Stock ownership can be transferred by legal decree, since it’s all on a centralized ledger.

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.

We've had to work through a lot of difficult issues in the debate over market structure in Congress (token classification, yield, shared agency authority). But we are now getting to the heart of the matter in the Senate: Whether Americans will be allowed to build and use permissionless private infrastructure in the US free from unwarranted prosecution (protected by the BRCA provisions in Clarity) or whether "national security interests" and "ease of prosecution" will trump those rights and protections. Another way to put this: Do you want the underlying pipes for all financial transactions to look like they have for decades: wholly owned and controlled by large banking interests and freely surveilled without warrants or reasonable suspeicion by corporations and the government? Or do you think that money and assets should travel safely and privately on free and open infrastructure that's built and maintained by the people for the people? Watch carefully who comes out on which side. Do you want some Republican to instantly know that you paid for an abortion? Do you want some Democrat to instantly know you bought a gun? Do you want either to be able to freely and arbitrarily cut you off from the global economic rails without trial or oversight? Or do you still believe in American values: privacy, liberty, and the rule of law?
