Why am I not at @web3privacy or @Web3summit? A few reasons … I am in trying out NymVPN in the most heavily censored country on earth - Turkmenistan.

NymVPN's ad blocker, powered by @brave 's legendary adblock engine and list, is out of beta and live on all apps. Thanks to the Brave team for the support during the integration. Ads aren't just annoying, they're surveillance tools! NymVPN stops them at the door. nym.com/blog/nymvpn-adblocke…

How ZCash dealt with the exploit identified by @DefuseSec was a good example. ALL software has bugs. And it always will. TLS had bugs for years. Every bank secures access to their customer portal with. What matters is 1) disclosure and 2) fixing the bugs to prevent damage.

There is also no easy solution, but overall using AI to find bugs will lead to more secure systems over time. AI also helps hardening cryptographic systems using formal verification, which I supported while I was at W3C and @Inria A DECADE ago: inria.hal.science/hal-016732…

We at @nym are practicing what we preach - our postquantum protocol is currently undergoing formal verification, and we run AI against our code to identify bugs. The future is MORE SECURE thanks to AI, not less. Bugs that are not discovered are timebombs. Let’s defuse them!

Do you have time to talk about our lord and savior: privacy? In the age of mass surveillance (now, FYI) and AI processing enormous amounts of data to find patterns that link accounts to the people behind them, a VPN can be a reliable friend: nym.com/pricing?ref=LsCRdUMD… Stay Gold!

Just completed my @nymvpn subscription payment with $NYM tokens through @keplrwallet. 1-year plan, and the final amount came to $17.34. No card, no bank, no extra friction. Just a simple crypto payment flow that actually worked the way it should.

#AEC functionallity now included in the @nym #Castor #email/#Usenet #Mixnet client. This is a real game changer in #email #encryption, as third-parties gain no longer access to the encryption process. #Nym #Mixnet #Encrption #AirGapped

Edgar Morin died today 😢 May he rest in peace, he remained deeply committed to morality and justice to the very end 👇 A very big loss.
Powerful words by 102 years old philosopher Edgar Morin, one of France's most revered intellectual figures, as well as a Jewish WW2 resistant who fought as a lieutenant in De Gaulle's France combattante. twitter.com/Bob30031583/stat… Here are his words on Gaza: "I am both astonished and outraged by the fact that those who represent the descendants of a people who were persecuted for centuries for religious or racial reasons... That the descendants of this people who are today the decision-makers of the State of Israel, that they could not only colonize an entire people, partly drive them out of their land and seek to expel them for good... But also, after the massacre of October 7, engaged in a real massive slaughter on the populations of Gaza and continue, incessantly, hitting civilians, women, and children. And to see the silence of the world, the silence of the United States, protectors of Israel, the silence of the Arab states, the silence of the European states who claim to be defenders of culture, humanity, human rights. I think we are living through a horrible tragedy because we are also powerless in the face of this thing that is unleashing. At least, I say: bear witness! The only thing that remains if we cannot resist concretely is to testify. Let's resist in our minds, let's not be fooled, let's not forget, let's have the courage to face things head-on."

Peter Thiel literally runs the United States government and yet he fled to Argentina, as the Nazi high command did before him, because things are so bad in the U.S. 🤔
Peter Thiel has temporarily relocated his family to Argentina, enrolled his children in school there, and bought property, partly due to Thiel’s concerns about the United States’ future, per NYT.

in 2026, privacy is growing bigger. - zcash > max transactional privacy - nym > network & metadata privacy - railgun > private DeFi on Ethereum - arcium > confidential computing on Solana they’re complementary layers. the smartest people aren’t choosing “one” - they’re building a complete privacy stack. where are you at with yours?

At a fundamental level, NYM seems to be one of the best long-term bets among decentralized currencies/tokens as investments: It technically solves and is poised to dominate an entire vital category, has a deflationary mechanism for tokeneconomics, and had a very low market cap.

📢 Protect your privacy with @nym Surveillance and the extraction of data and metadata have intensified in recent years. This creates various dangers to our privacy. With the arrival of AI, the capabilities of various actors to monitor our lives and even finances have increased, putting our security at risk. This means that conventional VPNs are no longer sufficient to protect us. In this bleak scenario, Nym VPN emerges to offer a tool that helps confront these sophisticated attacks on our privacy. In this talk, we'll have Rocío and Diana, Nym Ambassadors, who will explain everything it offers and how to use this VPN like a ninja. Don't miss this Live event. There will be POAP! We'll be waiting for you! 🧭 DETAILS 📞Medium: Live 📍Location: X (Twitter) 🗓Date: May 29, 2026 🗓Time: 13:00 UTC

🆔A social media ban = “digital ID checkpoints for the whole population,” @silkiecarlo warns on @Channel4 We must avoid anything like a digital ID system for the internet that would both eradicate privacy online & fail to keep children safe.
