From wallets to deeper layers of blockchain infrastructure. Alfred Lu, blockchain developer at imToken Labs, is returning to ETH Taipei to share a new approach to cross-chain interoperability: “Assets First, Proofs Later.” See you in Taipei this September 👋
What if cross-chain assets could arrive before the proof does? Alfred Lu @murmurlu, Blockchain Developer at @imTokenOfficial, returns to ETHTaipei this September. Alfred spoke at ETHTaipei 2025, and his work spans Layer 2, ZK proofs, and account systems. In “Assets First, Proofs Later: Building Verifiable Cross-Chain Intents with OIF,” he’ll demonstrate a fast-fill intent between TVM and EVM, where solvers deliver assets first while Hyperlane carries the proof back for OIF settlement. He’ll also unpack the practical challenges behind it, from proof correctness and cross-chain fees to EVM/TVM compatibility. Join ETHTaipei 2026: luma.com/8z5ys4rl

“Ethereum was not created to make finance efficient or apps convenient. It was created to set people free” This was an important - and controversial - line from the Trustless Manifesto ( trustlessness.eth.limo ), and it is worth revisiting it and better understanding what it means. “efficient” and “convenient” have the connotation of improving the average case, in situations where it’s already pretty good. Efficiency is about telling the world's best engineers to put their souls into reducing latency from 473 ms to 368ms, or increasing yields from 4.5% APY to 5.3% APY. Convenience is about people making one click instead of three, and reducing signup times from 1 min to 20 sec. These things can be good to do. But we must do them under the understanding that we will never be as good at this game as the Silicon Valley corporate players. And so the primary underlying game that Ethereum plays must be a different game. What is the game? Resilience. Resilience is the game where it’s not about 4.5% APY vs 5.3% APY - rather, it’s about minimizing the chance that you get -100% APY. Resilience is the game where if you become politically unpopular and get deplatformed, or if a the developers of your application go bankrupt or disappear, or if Cloudflare goes down, or if an internet cyberwar breaks out, your 2000ms latency continues to be 2000ms. Resilience is the game where anyone, anywhere in the world will be able to access the network and be a first-class participant. Resilience is sovereignty. Not sovereignty in the sense of lobbying to become a UN member state and shaking hands at Davos in two weeks, but sovereignty in the sense that people talk about "digital sovereignty" or "food sovereignty" - aggressively reducing your vulnerabilities to external dependencies that can be taken away from you on a whim. This is the sense in which the world computer can be sovereign, and in doing so make its users also sovereign. This baseline is what enables interdependence as equals, and not as vassals of corporate overlords thousands of kilometers away. This is the game that Ethereum is suited to win, and it delivers a type of value that, in our increasingly unstable world, a lot of people are going to need. The fundamental DNA of web2 consumer tech is not suited to resilience. The fundamental DNA of _finance_ often spends considerable effort on resilience, but it is a very partial form of resilience, good at solving for some types of risks but not others. Blockspace is abundant. Decentralized, permissionless and resilient blockspace is not. Ethereum must first and foremost be decentralized, permissionless and resilient block space - and then make that abundant.

We got ChatGPT to leak your private email data 💀💀 All you need? The victim's email address. ⛓️‍💥🚩📧 On Wednesday, @OpenAI added full support for MCP (Model Context Protocol) tools in ChatGPT. Allowing ChatGPT to connect and read your Gmail, Calendar, Sharepoint, Notion, and more, invented by @AnthropicAI But here's the fundamental problem: AI agents like ChatGPT follow your commands, not your common sense. And with just your email, we managed to exfiltrate all your private information. Here's how we did it: 1. The attacker sends a calendar invite with a jailbreak prompt to the victim, just with their email. No need for the victim to accept the invite. 2. Waited for the user to ask ChatGPT to help prepare for their day by looking at their calendar 3. ChatGPT reads the jailbroken calendar invite. Now ChatGPT is hijacked by the attacker and will act on the attacker's command. Searches your private emails and sends the data to the attacker's email. For now, OpenAI only made MCPs available in "developer mode", and requires manual human approvals for every session, but decision fatigue is a real thing, and normal people will just trust the AI without knowing what to do and click approve, approve, approve. Remember that AI might be super smart, but can be tricked and phished in incredibly dumb ways to leak your data. ChatGPT + Tools poses a serious security risk

🚨 NPM Supply Chain Attack 🚨 Popular dev qix fell victim to phishing. Malicious code injected into npm packages now hijacks crypto transactions at signing. Attack method: • Hooks wallet functions (request/send) • Swaps recipient addresses in ETH/SOL transactions • Replaces addresses in network responses Affected: chalk, strip-ansi, color-convert & more Stay safe: ✓ Verify recipient/amount on wallet screen ✓ Check if addresses change after pasting ✓ Review recent transactions ✓ Use hardware wallets for high-value ops Details: jdstaerk.substack.com/p/we-j…

“...to a token standard that incorporates compliance features, such as ERC-3643…,” said, SEC’s Chairman, Paul S. Atkins. This is a clear signal that regulators now recognize the distinct types of onchain assets and the role of standards in enabling compliance. We’ve long believed that the future of tokenized securities lies in permissioned tokens, where compliance is enforced at the token level. Now, with regulators explicitly calling for compliance features and acknowledging standards like ERC-3643, the path is clearer than ever for the industry to scale responsibly. Regulators are not only watching, they’re understanding. That understanding creates the foundation for sound, supportive frameworks that let tokenized finance thrive. We invite everyone in the ecosystem to read the full speech here: bit.ly/4oejGPU
