@follard Also wrong is the idea that the IRS takes 25-35% on the way out. Taxation on retirees is so light as to almost be laughable...with tax planning most people are paying nowhere near those rates

[David McIntyre @mcintyre]

@follard Yeah there is a lot wrong with this argument, starting with how it ignores that contributing to a 401k 1) gets you free money from employer matches and 2) reduces your taxable income in your highest-earning years

Big announcement from portfolio company @doublezero!

As new finance grows, a new infrastructure layer is taking shape. DoubleZero Edge delivers Kalshi market data over its dedicated fiber network using multicast, an architecture major exchanges have relied on for decades.

[Kyle Samani @KyleSamani]

Kalshi x DoubleZero

Two of my favorite things!

[Andrew McConnell @malbeclabs_cto]

Multicast market data over dedicated fiber is how NASDAQ, NYSE and the CME have worked for decades.

@Kalshi's order book now runs on the same model over @DoubleZero Edge, open to anyone who connects rather than the few firms that could build it themselves.

[David McIntyre @mcintyre]

@doublezero takes a huge step forward today with the launch of @Kalshi feeds - the growth of prediction markets is one of the biggest financial stories and now DZ can help traders access these markets better and faster.

[Austin Federa | 🇺🇸 @Austin_Federa]

Prediction markets have become critical financial infrastructure, so we decided to treat them like that.

Announcing low latency Kalshi order book data on @DoubleZero Edge - the fastest feed of what's happening on @Kalshi.

[DoubleZero @doublezero]

Prediction markets just got Wall Street-grade trading infrastructure.

@Kalshi’s live order book is now streaming on @DoubleZero Edge, a multi-venue, real-time market-data platform.

Institutional-grade market data is now open to anyone, anywhere.

[Triton One 🌊🌋 @triton_one]

Two launches today, and together they're the fastest streaming products on Solana!

🌊 Riptide, our new low-latency endpoint for Dragon's Mouth gRPC. Same stream, same filters, same SDKs, same tokens, same price. One URL change and you're on it

🚀 Triton Shred Streaming (in beta), raw shreds forwarded straight to your servers from New York, London, Amsterdam, Frankfurt and Tokyo, sourced over @DoubleZero's private fibre

💰 Coming soon: a $50,000 trading competition with @DoubleZero. Trade on institutional rails, win on strategy

[Jesse Livermore @Jesse_Livermore]

Hard to even process -- a president selling market-moving information to banks and wealthy investors in advance of everyone else, and personally pocketing hundreds of millions of dollars from it. This alone is more worthy of impeachment than 100 Watergate cover-ups.

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.

More s00n.....

[DoubleZero @doublezero]

DoubleZero Edge is designed to be the fastest shred delivery service on @Solana.

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.

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, @Helius, @jump_firedancer, @triton_one, and @harmonic_gg are all in

Validators: You weren’t making money on your shreds before. Now you can.

[DoubleZero @doublezero]

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: https://t.co/WAGnIHfAsI

[DoubleZero @doublezero]

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.
