Q1 2026 DoubleZero Network Update… Here’s a recap of the last 90 days: → Launched DoubleZero Edge which now carries ~50% of @Solana’s network stake, representing 400 validators → Hit 51% of @Solana’s network stake operating on DoubleZero’s high-performance rails, representing 460 validators → 100 traders, market makers, MEV searchers subscribed to DoubleZero Edge → Increased dedicated bandwidth on the network to 9.71 Tbps contributed by 15 independent organizations → Brought Wall Street trading-tech, known as multicast, onchain for the first time in history → Joined @fund_defi and 30 industry leaders to request that the SEC formalize the principles in its recent Staff Statement—distinguishing non-custodial UIs from broker activities—in notice-and-comment rulemaking, so we have durable regulatory clarity that lasts. → Brought validator fees to ZERO, and introduced a new revenue stream for publishing shreds → Improved link networking speed for @Solana by an average of 22% → Reached $18B in Total Connected Value (TCV) on DoubleZero’s dedicated fiber network And on top of all that… we’re proud to say that in the background: Phase II of the DZDP successfully pushed Europe’s share of @Solana stake below 66.66% for the first time in at least two years of recorded data. A massive win for global network decentraliztion.

What is not reflected in this article is the need for a 3rd venue. Dads today exist in two places: Work & Home. The challenge (at least IMO) is in order to routinely be present in those 2 venues you need borrow time from the 3rd. Spend less time working out, seeing friends, trying resturants, playing guitar, whatever it is. Demands grow exponentially for dads. Expenses on the home front necessitate higher performance at work. Increased workload demands more time, squeezing even more free time from the fleeting venue 3. To all the dads out there - find a 3rd venue for your time. It could be gym, music lessons, whatever (just don't make it drinking at a pub alone). There are incredible returns both at work and at home if you can find a productive outlet for yourself.
New newsletter: MODERN FATHERHOOD WOULD BE UNRECOGNIZABLE TO A 1950'S DAD Compared to their Boomer parents, childcare time among Millennial dads has more than doubled. Compared to their Silent Generation grandparents, it’s nearly quadrupled. You will be hard-pressed to find any part of day-to-day modern life that has changed more in the last half-century than the way today’s parents—and fathers, in particular—spend their time. The new American dad is more present and more exhausted—but also, more satisfied with life. What's behind this half-century transformation? Today's piece combines history, economic analysis, and gorgeous charts galore from @AzizSunderji

I strongly encourage you, if you’ve never been to Yellowstone, not to let these doomer posts bum you out. You can go to Yellowstone at peak and not experience any of this, you come in via the Cooke City NE entrance early morning, watch thousands of animals (wolves, elk, prongs) in the Lamar Valley, which is your heritage as an American, see the park, and not see any of this clusterf*ck. Sometimes you have a bad visit and you hit a jam, have some snacks and huckleberry beers in the car, so what, it’s worth it. Don’t skip it because you see the worst aspects of a visit posted online. Now, with that out of the way, the thing about the National Park crowding in America is you basically have 4 options, and 0 of these 4 are things that people want or like. I’m going to put a poll in the replies and maybe you vote on the one you like for me? First is you have “ticketed timed entry,” so if you don’t book on Rec dot Gov 6 months out, sorry but you’re probably not getting in during peak season. This is in place at high demand parks like Arches or Going to the Sun Road in Glacier. These work well for people who can plan their lives 6 months in advance, but you lose the spontaneous American summer road trip which is a big part of the culture. Also, gate employees are suffering from unprecedented harassment and turnover from people who pull up to get in, have no idea they need a booking, and go ham on the 20 year old GS5. Option two is some form of dynamic pricing, lots of economists put ideas out like this but the social justice equity people wail about it, and I get that, you want Americans to access public land regardless of how much they make. This is probably my preferred option though, if you want to go during peak, be prepared to pay. People aren’t ready for a mid June $500-1000 YNP entry fee though, so it’s probably not really feasible. I also don’t think that’s the purpose of entry fees per the statutes that authorize our National Parks so it would be tricky. Third option is what we have today, everyone can enter but some lots (Norris, Grand Prismatic) are going to be a massive thorn in the side. The roads and lots were all designed for demand 50-100 years ago. There’s always parking over by old faithful, and a nice bar in the Old Faithful Inn. There’s always somewhere neat to see that’s not doomered out. Fourth option is you’re required to leave your car and take the shuttle around. This is in place in Zion and some parts of Rocky Mountain up near Bear Lake. Americans (including myself) like our cars and don’t necessarily want to want 30 min for a shuttle after a 10 mile hike with a bunch of kids, but this is probably the future of Yellowstone. Vote your preference in the reply for me if you want to.
Is this what you thought Yellowstone Park was like? Unmoving traffic jams lasting 1-3 hours; rivaling that of suburban areas in big cities. Nowhere to park. Insane prices. Tourists harassing animals, littering, picking flowers, influencers everywhere, sticking their hands in basins and ruining them, no good camping spots left because people use AI programs to snatch up the good ones within milliseconds of the site opening up, and most of your day spent behind Asian tourist busses. The overwhelming amount of tourists have made the park experience unbearable. You used to be able to go there and explore nature peacefully. Now it's worse than Disneyland.

Announced DoubleZero Edge yesterday. Here’s where we are, 24 hours later. - 14.7% of the @Solana network is now publishing shreds - That’s at least 221 validators actively publishing shreds via DoubleZero Edge right now - 282 validators are now connected to multicast (almost a 3x from yesterday) - @jito_sol, @Helius, @jump_firedancer, @triton_one, and @harmonic_gg are all in Validators: You weren’t making money on your shreds before. Now you can.

4/ The technology on DoubleZero Edge: multicast Multicast is how financial exchanges have distributed market data for a decade. One transmission, every subscriber in a region receives it at roughly the same moment, with orders of magnitude less bandwidth required by the sender, and the network. Multicast is now available on blockchain for the first time via DoubleZero. Connecting to multicast now qualifies you to receive shred revenue from day one when Edge launches with subscribers… (s00n). Connect. Publish. Earn: doublezero.xyz/multicast-con…

2/ First: Zero fees. The 5% block reward fee is gone for every existing and new DoubleZero-connected validator, effective as of Epoch 939. Now carrying ~46% of Solana’s network stake, DoubleZero is maturing from a bootstrap protocol into an economic engine for Solana. Validators are not paying fees anymore. You’re getting paid, through the protocol. Read on…

Huge day for @doublezero as we announce DoubleZero Edge. Trading is the most important use case for fast blockchains and this service will make critical data available to all at the fastest possible speeds.
We spoke with @Forbes to take a deep dive into how blockchain market infrastructure is evolving. Read the full story ↓

DoubleZero in @Forbes "Blockchain trading presents a challenge with no real equivalent in traditional finance. Imagine if the New York Stock Exchange jumped to a different location around the world every 1.6 seconds: now in New York, now London, now Singapore, now Hong Kong. That is exactly how a blockchain works, with the block leader rotating globally and constantly. Existing data distribution systems were never designed for this." forbes.com/sites/digital-ass…

Rather awkwardly, the most innovative part of the Vegas Loop is the multi-coloured lights. The Boring Company are very proud that, over five days, they were able to carry 16,400 passengers per day - using a system that takes everything that is inefficient about cars and tries to pretend it is a form of public transport. To put it into perspective, London’s Elizabeth Line carries 800,000 passengers per day and almost as many in one hour as The Boring Company achieved during the whole expo. Even in the late 19th century, the Metropolitan and District Railways were running trains roughly every 2–3 minutes at peak once the system matured, ferrying 12,000–18,000 passengers per hour per direction. And that was steam-powered using infrastructure built 160 years ago. So, to be clear, Elon Musk’s “future of transport” transports between three and four times fewer people per hour than we were able to do in 1863 London. Urban transport efficiency comes from large vehicles, shared journeys, and frequent service. Cars — whether they’re electric or autonomous or on roads or in tunnels — do the opposite. If the goal is moving lots of people quickly through cities, why design a system with the same constraints as cars? Cities: please don’t waste any more time or money on this. We have the solutions: trains, metro, trams, buses and bikes.
Vegas Loop safely moved ~82,000 passengers at the amazing @CONEXPOCONAGG construction trade show. @LVCC

3 Prem managers have now been fired this season after making pointed public comments about their club's hierarchy (Nuno, Maresca, Amorim). They basically asked to get fired, refused to quit, and so are owed the full amount of their contracts. Pretty good gig if you ask me 😂

4/ @doublezero is a high-performance global network that accelerates blockchains with direct, low-latency fiber from many independent contributors. They’re joining BA to highlight the importance of decentralized infrastructure in policy discussions, having recently received a No-Action Letter from the SEC.

When I read this NYT article on the SEC's approach to crypto yesterday, I was outraged and submitted a comment on the article that has not been approved. I suspect it may not ever be approved. I happened to save the text since I was on my phone and paranoid about losing the comment. Here is it: This article is seriously lacking in context. Biden’s SEC did not stop any of the many frauds in crypto. They were buddy-buddy with Sam Bankman-Fried, one of the biggest fraudsters in HISTORY, and missed FTX, Terra/Luna, Three Arrows Capital, Celsius, Voyager, etc. Instead, they went after upstanding companies for registration infractions, which aren't anywhere near as important for its goal of investor protection. It makes perfect sense that the Atkins SEC should now drop a number of these frivolous, wasteful lawsuits. The Gensler SEC’s refusal to create guidance as to how existing laws from the 1930s/1940s applied to crypto is partly responsible for the fact that FTX was offshore, giving investors less protection. If the Gensler SEC had been clear about how the rules applied, then companies (and consumers) could know ahead of time what was/wasn’t kosher. Instead the SEC kept secret exactly how the laws from the 1930s and 1940s applied to crypto and would surprise crypto companies with lawsuits. This is not a fair or normal way to run a government agency. It was also supremely stupid since the companies they went after were largely good actors. Lastly, more than half of crypto people are/were Dems who voted for Trump because of Gensler’s antics. They don’t love Trump’s business conflicts with crypto either. I advise you to never learn a lot about a subject, because once you see how much the NYT gets wrong, it will make you question EVERYTHING they report on.
i really want to believe that NYT is trustworthy but that has become nearly impossible the whole framing of this new crypto story (yet again) relies on the (false) premise that the prior admin’s attack on crypto totally normal it wasn’t the attack was widely rebuked for years — by bipartisan members of congress, by federal courts, by basically anyone that wasn’t part of a small cabal of elizabeth warren-aligned officials. mainstream democrats never took up her cause. one time the dem senate voted overwhelmingly to overturn an insane SEC policy and biden was forced to VETO it these partisans, who often owed their jobs to a deal struck between biden and warren during the 2020 campaign (widely reported) included consequential appointees in the biden admin who previously worked directly for her, or those who she personally approved. these partisans included staffers for regulators who immediately went to warren-aligned non-profits like better markets and the consumer federation of america. these included entrenched officials inside banking regulators, who have now been exposed for inappropriately targeting legal industries so the idea that the regulatory pivot on crypto over the last year is somehow because of the president’s personal interest, and not because the prior regulatory posture was absolutely INSANE, is dishonest framing that ignores 4 years of direct attacks by the actual partisans this type of reporting relies on the readership being uninformed, which unfortunately too many are. this relies on Gell-Mann Amnesia and the “paper of record” is actively promoting crypto dementia
