Solana's read layer 2.0 is now open source: Superbank (history) and Cloudbreak (accounts), marking the end of vendor lock-in for chain access. Querying @solana should feel like calling a real database, so we built exactly that. 🟣Lightning-fast account reads with dynamic indexes from your query patterns 🟣Your own queryable copy of Solana history, with no indexing logic to write 🟣More performant than Agave, while running on commodity hardware Fork it, run it, improve it. It's yours 🌊🧵x.com/solana_devs/status/206…
Introducing the Solana RPC Working Group Its mission is to advance Solana's open-source RPC stack, making the read layer more accessible for all. Built in the open by @triton_one, @Helius, @JupiterExchange, @anza_xyz, and @SolanaFndn 🧵

Nobunagasama is Modern day Hemingway
USA. A Mexican restaurant. We had not yet ordered anything, and the food was already arriving. Chips. Salsa. Unrequested. Free. I stopped the waiter. "We have not earned these." "They just come with the table, man." They come with the TABLE. In my land, hospitality is a debt. Every gift creates an obligation, weighed carefully, returned in the proper season with interest of feeling. Here, the gift arrives before you have even proven you can pay for dinner. This is not an appetizer. This is a declaration: we trust you. Eat. I ate with the gravity the moment deserved. And then — I must report this calmly — the basket emptied, and a new one appeared. "Did we…?" "Refill," the waiter said. "It's bottomless." Bottomless. They have wells of salsa. The supply lines of this nation are beyond anything my ancestors imagined. My friend warned me. "Don't fill up on chips, dude." Too late. I had accepted three baskets. Honor demanded each one be finished — an unfinished gift is an insult. By the time my actual food arrived, I was a ruined man. I was not hungry. I was not comfortable. I had been defeated by a courtesy. Generosity that arrives before the request cannot be repaid. It can only be survived. I know the rule now. I have made my peace with the basket. One basket. Two at the most. Who am I deceiving. There is no number of baskets I would refuse. The trust of a nation is in that salsa, and I intend to honor all of it.

Europeans keep asking what American culture looks like. Brother, we have a restaurant so reliable that the federal government unofficially uses it to judge hurricane damage. It's called the Waffle House Index. If the Waffle House is open and serving a full menu, everything is probably fine. If they're on a limited menu, things got rough. If the Waffle House is closed, FEMA starts paying attention. Think about how absurd that is. An entire nation's disaster response can be summarized as: "Yeah, but is the Waffle House open?" And despite the jokes, it's one of the greatest American institutions ever created. 24 hours a day. 365 days a year. Friendly waitresses who call you "baby." Hot coffee that somehow tastes better at 6 a.m. after a road trip. Bacon, eggs, hash browns, waffles, and burgers cooked right in front of you. I recommend the hashbrowns smothered and covered No reservations. No dress code. No pretension. Just good food, good people, and a front-row seat to the greatest collection of characters you'll ever meet. Sure, there's a non-zero chance you'll witness a fight. But there's also a decent chance you'll sit next to a truck driver, a nurse getting off a night shift, a family on vacation, and a local farmer all having breakfast together. That's America. When a hurricane hits, Waffle House is often the first businesses to reopen. When your flight gets delayed. When your team loses. When you're driving across the country. When it's 2 a.m. and you need food and life advice from a waitress named Amanda. Waffle House is there. Buc-ee's is America's cathedral. Waffle House is America's church.

According to the Washington Post’s @DanLamothe, the U.S. Navy drone that aided in the rescue of two U.S. Apache helicopter crew members was a Saronic Technologies Corsair unmanned surface vessel (USV). First deployed in the U.S. Central Command AOR in March of this year, the USV reportedly picked up the two soldiers and then took them to a secondary location where a waiting helicopter hoisted them up. Such a rescue would be the first time that such a system was used in this role.

I'm finally reading Dune. This quote, which is in the first few pages, hits hard: "Once men turned their thinking over to machines in the hope that this would set them free. But that only permitted other men with machines to enslave them."

Formal verification is indeed the way. A few years ago I reached out to @NotDeGhost asking him if he wanted to do the first formal verification for a Solana program. Luckily he said yes and got it done in 4 months. Since then all Squads programs have gone through that process multiple times. Fast forward to today, we now also have Certora and many of the core ecosystem programs formally verified. The biggest issue with FV is that it takes time and is very expensive. While the AI security apocalypse is stressful, it is also obvious that LLMs will help us drastically compress the time and cost it takes to prove the mathematical integrity of onchain codebases. Maybe that will be the silver lining of it all.
There's a lot of confusion about the recently patched Zcash bug. Here's how to actually understand it. If the bug had been exploited before the patch (very unlikely it was), it would have looked like the shielded pool getting drained. Whoever minted the counterfeit shielded ZEC would want to sell fast, before anyone else found the same bug. And remember, the market for ZEC is almost entirely transparent ZEC, not shielded. You can't dump freshly minted shielded ZEC on Binance or Coinbase without unshielding it first. The losers in that scenario are shielded holders who sit still. The transparent portion of Zcash is fully visible, so it's trivial to enforce that transparent ZEC never exceeds max supply. If you try to unshield more than the cap, you'll get stopped at the door. So if you hold transparent ZEC (anyone trading, on an exchange, or doing price discovery on ZEC) there's no marginal effect on you. The loss falls entirely on shielded holders. The team's next step is a new turnstile and a fresh shielded pool in the coming upgrade, which will confirm the shielded pool was not inflated. Think of it as taking headcount at the end of the field trip--that will make sure no extra kids snuck onto the bus. But while AI found this bug, AI will also deliver the fix for the whole category: formal verification. I'm very bullish on this as the path to harden all software across the industry. Formally verified cryptography can't have implementation bugs by construction. Right now AI is surfacing vulnerabilities across all our software--browsers, OSes, and blockchains are no exception. We're in the awkward adolescence where every wart is getting magnified and put on full display. But formally verified software is the only path forward for mission-critical software, and Zcash has put it front and center on their roadmap to deliver. Privacy is too important not to. (Dragonfly holds $ZEC and continues to. I'm personally an investor in ZODL.)

The concerted shilling of Zcash that started last year makes more sense when you consider someone was probably minting and dumping endless supply the entire time

hey chat just got out of an emergency meeting at solflare. turns out we have so many things shipping in june that we physically cannot tell you about all of them in time and some of you will simply find out by accident. this is a genuine operational problem. anyway what should we do
