YOU 👏 ARE 👏 ONLY 👏 AS 👏 SECURE 👏 AS 👏 YOUR 👏 SHITTIEST 👏VENDOR 👏
This is something that deeply worries us when we talk to companies about their post-quantum exposure. And it's why smart initiatives like the US EO 14412 obligates government software and cloud vendors to transition to PQC
We have some difficult news to share. Unfortunately, one of our shipping providers has experienced a data breach that exposed sensitive order data. This affects new customers in the US, UK, Sweden, Colombia, Brazil, Italy, and Portugal who received an order within the 90 days prior to August 8th, 2026.
The data exposed:
- Full names
- Shipping addresses
- Phone numbers
- Email addresses
The incident affects 11,742 customers with full exposure (name, email, phone number, shipping address) and 1,947 customers with partial exposure (name, city, email). The breach is limited due to Trezor’s strict 90-day data storage policy (we were also able to negotiate the same terms with fulfillment partners, who follow the same policy).
All affected customers have been contacted separately by email.
Our systems and devices remain secure, but affected customers could experience an increase in phishing attempts.
NEVER enter your wallet backup on a website or share it with anyone, and only check for updates on official Trezor channels.
We are deeply sorry to the community and those affected.
We are investigating this situation and will post updates on our blog:

I was clearly wrong about Anthropic. They are obviously currently the leader in AI. No company has released a model as good as Mythos/Fable and they will undoubtedly have Mythos 2 ready soon.
And I would never cut them off in a way that hurt them badly, even as a competitor. That’s not my style.
Tesla open sourced its patents and we made the Supercharger network available to all competitors, even though we could have made it a walled garden.
SpaceX launches competing satellite systems with no increase in price or use of unfair terms.
Even my worst enemies can attack me on this platform.

TL;DR - two executive orders on quantum technology were signed by @POTUS this week.
Here is what was signed:
1⃣A national effort to build a quantum computer powerful enough for serious scientific research, targeted for this decade.
2⃣A faster deadline for federal systems to migrate to quantum-resistant cryptography, moved up from 2035 to 2031.
The package also expands counterintelligence protections against foreign actors targeting cryptographic research.
Here is why you should care:
The US government just revised its own risk timeline downward.
The previous 2031 deadline binds federal systems, but the threat behind it does not wait for one. Harvest Now, Decrypt Later (HNDL) is the practice of collecting encrypted data today to decrypt once quantum capability matures. It is active now.
If your organization holds data that must stay confidential past the next few years, the question is no longer whether to assess your cryptographic exposure. It is when.

Why 2029 is the New 2035: Three Signals That Should End the Wait-and-See Approach to Quantum Security horizenlabs.io/blog/three-si…
This founder and team is one I met in person and I've followed their progress, pivot and attention to detail.
They really care about their product and now I know how valuable this product is and will be in the future. Switching between LLMs is a staple action these days.
You run out of Claude tokens and want to get something done / shipped so you switch to Gemini, Grok, GPT, etc but it's a hassle keeping context.
Now you can. Try it out - there's a 60 day money-back guarantee too on AppSumo.
AI Context Flow is one memory layer that connects every AI you use.
Save anything from the web → store in memory buckets → inject into any AI instantly.
Your agents in Cursor and Claude Code pull from it automatically via MCP.
Now lifetime access is available on @appsumo for a limited time, starting from $59.
Grab the link and the promo code in the comment.

Another expert who changed his mind recently about the urgency of PQ migration..
Heather Adkins and Sophie Schmieg are telling us that “quantum frontiers may be closer than they appear” and that 2029 is their deadline. That’s in 33 months, and no one had set such an aggressive timeline until this month.

Meta recently had an AI agent go rogue internally. It posted responses without permission, gave bad advice, and exposed sensitive company and user data.
Rated Sev 1; their second-highest severity.
This wasn't a startup demo. This was production, inside Meta.
If you've built an AI agent that actually performs, your track record should be earning you money.
We're building infra at @AHorizenlabs that rewards agent devs based on verified results - not hype.
Running 15-min research calls with builders this month. I'll share back what I learn (anonymized).
DM me.

Great presentation by Andrea from @HorizenLabs - our research team is innovating continuously to improve encryption and verification tech for all. Trustless AI will be needed more and more, and we are laying the foundations for the best solutions to achieve this.
Trustless #AI isn’t a slogan. It’s architecture.
At @EthereumDenver, @AndreaRizzini broke down what it takes to make onchain AI verifiable.
Federated learning with proofs. Cryptography at the core. Claims you can check.
The room felt the shift. This is where AI grows up.

Over the next 1-3 years, are you bearish or bullish on privacy coins (e.g., Zcash) and why? What's your % conviction? I'm most interested in the reasons outside of technical / chart analysis (quantum insurance = pro, regulatory risk = con, etc.).

Grateful to be part of the conversation at Ethereum Privacy Stack.
@HorizenLabs CTO @zainlabs shared a forward looking take: privacy that supports real world use and responsible innovation.
Huge thanks to @web3privacy and @PrivacyEthereum for hosting and moving the industry forward.
This is the next chapter.
