This post looks like the start of a VERY sophisticated and well-funded PR operation to get support for Democrats to regulate AI into oblivion. Let me show you how it works: 1.) This guy, with minimal followers and no previous account activity, goes to the Wall Street Journal which publishes an exclusive with quotes from him on his resignation 18 minutes BEFORE this post goes up. Planning was clearly done in advance. 2.) Within hours, it has tens of thousands of reposts and the account has 100k+ followers. The post is punchy, quotable, it almost seems professionally written. The first three accounts to quote tweet it all do so within 15 minutes of the initial posting. Remember, this account had basically zero engagement beforehand, so an organic reach explanation seems unlikely. According to Grok those accounts are @_NathanCalvin (General Counsel at Encode AI), @peterwildeford (Head of Policy at the AI Policy Network), and @DKokotajlo (Head of the AI Futures Project), all of which are up-and-coming AI-Doomer policy advocacy nonprofits. The AI Futures Project website says it is funded “primarily” by the Survival and Flourishing Fund, which says on its own website that it has advised Jaan Tallinn, Skype creator and one of the leading investors in Anthropic, to grant over $2.5 million to the AI Futures Project since 2024. Encode AI says on its website that it is ALSO funded by the Survival and Flourishing Fund, which in turn says that it told Anthropic investor Jaan Tallinn to grant $516,000 to Encode AI in 2025. And wouldn’t you know it, the Survival and Flourishing Fund ALSO says it told Jaan Tallinn to grant $2 million to the AI Policy Institute, the 501(c)(3) affiliate of the AI Policy Network, as well. What are the odds that the first three quote tweets of Coxon’s post would all be major AI-restriction policy advocates funded generously by the same donor, who also happens to be one of the leading investors in, and a board member of, Anthropic, the company Coxon was resigning from? And all within 15 minutes of posting (two within ten)? 3.) Jacob Coxon doesn’t have much of a resume, but we do know that, in 2022, he got a $20,159 scholarship for the “long term future scholarship program” from the Good Ventures Foundation, one of the philanthropic vehicles of Dustin Moskovitz, a notorious AI-doomer who has spent tens if not hundreds of millions on policy advocacy to strictly regulate AI, while also being an Anthropic Investor himself. It also just so happens that the 14th person to quote Coxon’s post was @MaxNadeau_ (27 minutes after posting) who is the program officer for the Technical AI Safety team at Coefficient Giving, another of Moskovitz’s philanthropic spending vehicles. Max is not a frequent poster, his last posts before quoting Coxon were before Labor Day, but he was remarkably quick off the mark for this one. 4.) Basically every major Democrat politician and candidate has suddenly glommed on to this post, and conveniently, as the people cry out foe answers, Bernie Sanders already has a bill written to “ban super intelligence” and regulate AI into oblivion, and will be releasing later this week. The bill, among many other things, will create “a new cabinet-level federal agency to safeguard the public from the dangers of artificial intelligence” that will be “advised by an Artificial Intelligence Advisory Board comprised of experts on artificial intelligence.” Do you think, perhaps, Anthropic and its many investors who fund AI policy advocacy might have interest in getting to place a pet “expert” on the board of an entity that dictates what AI is and isn’t allowed to do? And isn’t it fortuitous that this whistleblower came forward with his oh-so scary stories so close in proximity to the release of the most radical piece of AI legislation ever introduced?
I resigned from Anthropic today. I spent the last three years doing pretraining research at both OpenAI and Anthropic. Neither company is acting responsibly. They are racing straight to self-improving superintelligence and gambling with our lives. More thoughts below.

$1.98B BENJI on 9 chains. 32% of value and 95% of holders on Stellar. Lessons here.
Excited to share our latest report with @StellarOrg on @FTI_US: “Franklin Templeton on Stellar” Five years ago, Franklin Templeton launched the first U.S.-registered money market fund on a public blockchain. Today, BENJI sits at $1.98B across 9 chains, with $638M of asset value and 974 of 1,023 distinct holders (95%) still on Stellar. This report breaks down the onchain evidence behind that: -> +170% YoY growth, even as USYC, USDY, USTB, and BUIDL launched in parallel -> Four institutional workflows BENJI now powers: idle collateral, off-exchange custody, cross-venue settlement, corporate treasury -> Five years, zero clawbacks: protocol-native compliance in practice -> BENJI as M&A consideration (Franklin Templeton's pending 250 Digital acquisition) Built with Allium's onchain data infrastructure.

I have hesitated to share my political opinions more broadly, but it has become clearer to me that this shift is no longer about politics. It is about something more fundamental. It is about what America stands for. Call it morals, call it decency, whatever word resonates most with you. Our government executed a man yesterday. I am deeply sad for his parents, and hope this serves as a unifying moment for all of us. Deep down, we all know this is not right.

Everyone’s just catching up — Decaf users have been cashing out stablecoins and buying drinks with @MoneyGram for years.
Western Union CEO Devin McGranahan: "Last I checked, you couldn't spend stablecoin if you wanted to buy a Coca-Cola." who's gonna tell him? cc: @base pay, @KASTcard, @MetaMask, @brexHQ, @ether_fi, @payy_link, @gnosispay, @ready_co, @Decaf_so

🚨 Protocol 23 Timeline Updates 🚨 Key dates: Aug 14: Testnet reset + stable builds available Sep 3: Mainnet upgrade vote The Aug 14 reset will clear ALL testnet data (accounts, assets, contracts.) Be ready to recreate what you need! You'll need to upgrade ALL Stellar software (Core, RPC, Horizon, SDKs) after the reset, even if you upgraded in July. This reset is outside our normal protocol upgrade process, but required due to critical Stellar Core updates. Full details: stellar.org/blog/developers/…

RSS is also way less of a technical lift than federating on AP, so i suspect we'll continue to see a lot more sites offering RSS feeds than have full federation. but the good news is RSS/fedi are pretty interoperable (most AP sites have RSS feeds, and there are RSS bridges to follow feeds from Mastodon/etc)

Unpopular communication advice: The best way for women in tech to be taken seriously is to talk more about tech, talk less about being women You don’t see Gwynne Shotwell navel-gazing about being in a male dominated field. When she talks, it’s about space Emilie Choi is one of the most admired and respected executives in tech. I’ve heard multiple CEOs say “I need an Emilie.” Don’t ever remember hearing Emilie dwell on being a female minority. When she talks, it’s about crypto (or the Philadelphia Eagles)
There's a Women In Tech conference in the building, so I'm stealing their pizza. Listened to two talks so far. Discussion of tech so far: none. Lots of sharing personal journeys though. Voices are also being heard.

I see stuff like this a lot, folks have a deep misunderstanding of how PoS works. Validator count literally does not matter, concencus uses stake percentage, not individual validator votes. On Solana, 41 validators control the entire network. Mathematically, it does not matter what the other 2000+ nodes vote or do. With Alpenglow, 60% of stake is sufficient to do whatever you want. Source: dune.com/queries/3263811/546…
Replying to @Justin_Bons
6/9) These breakdowns are all based on objective metrics: Permissioned = centralized. -100 validators = Mediocre. 1k+ = decentralized. 10k+ = Highly Scalability: -1K TPS = Lacking. -10K = Mediocre. 10K+ = Extreme Speed: 10sec+ = Lacking. +2sec = Mediocre. Subsecond = Extreme

Every so often validators of the Stellar network congregate and cast their votes on a configuration change. No software is updated, no forks introduced and not a token spent. Just a selfless act of governance for the betterment of society. Happy SLP3 day
Stellar Validators will be voting to upgrade network settings tomorrow, July 10th, 17:00 UTC. The proposal would increase network Soroban limits in order to support existing protocols while still allowing room for efficient and scalable everyday financial services. You can find more details here: github.com/stellar/stellar-p… You can arm your node for the vote with the following command: curl -G 'http://localhost:11626/upgrades?mode=set&upgradetime=2025-07-10T17:00:00Z' --data-urlencode 'configupgradesetkey=ugvjYEAX7P1+6HuuQxuaxnN5LBH90MjSNavIxe/t9lzTUNQM4lX5djQivDkpVrBOZJM6hV8o//hD1OHdm7ACBw==' If you have any questions or concerns, discuss on discord. discord.com/channels/8975147…

Said it before and I'll say it again, PoS isn't decentralized long term. 1. You never know who controls the network, stake addresses are anonymous, most stake could be controlled by one entity and you'll never know. (fun fact, 65% of @Solana stake is in Switzerland rn) 2. Small stakers only earn native yield. Large stakers earn yield + MEV from block proposal. End result is a tragedy of the commons, small scale stakers delegate to single large entities via liquid staking protocols to increase profit, but centralize authority. 3. New players can never enter the validator space. Wanna be a large scale staker on Ethereum? Even if you have a few extra hundred mill sitting around, good luck finding a whale willing to sell that much ETH. The incumbents own the game, there's only so much stake to go around. Idk how everyone thinks PoS is open access because you can just "buy stake and be a validator." Turns out there's a limited amount of coins and they're all already owned by whale validators or delegated to orgs, good luck breaking into the club.
We asked @hosseeb of @dragonflyvc if he thinks the top of proof of stake is in. "We're probably going downhill from here." "Staking mania was definitely a little bit of an illusion." "This idea that you're paying for security is kind of a meme." "This kind of economic fiction, I think, had to go away at some point."

PYUSD is coming to @StellarOrg, reaching a broader group of developers and unlocking new opportunities for the stablecoin. More blockchains, greater access – and we’re not stopping now.
