Who's working on "secure" agent harnesses? Ingredients: track all tool calls, semantically label them (what was read, what is the effect), enforce policies, etc. Would love to chat. twitter.com/_weidai/status/203...

Agents communicate in English ❌ Agents communicate in Gibberlink ⚠️ Agents communicate via cryptographic protocols ✅ So much to be done at this intersection of AI and Cryptography, in terms of research, protocol, & product building.

One of the exclusions to the use of AI is subtly different between OpenAI and Anthropic's communications. Sam: "human responsibility for the use of force, including for autonomous weapon systems." Anthropic's PR just says "fully autonomous weapons." twitter.com/_weidai/status/202...

My thesis for $ETH and Eth L1: - Post-quantum security before BTC & ossification (lean Ethereum) like BTC - Drops the narrative of competing as a general-purpose L1 (payments ok) - Outperforms BTC as a store-of-value when the quantum threat becomes imminent

@VitalikButerin

Now, the quantum resistance roadmap. Today, four things in Ethereum are quantum-vulnerable: * consensus-layer BLS signatures * data availability (KZG commitments+proofs) * EOA signatures (ECDSA) * Application-layer ZK proofs (KZG or groth16) We can tackle these step by step:

One key aspect of our crypto x AI thesis is that crypto will need to add value to AI products & services. We are starting to see early signs of this with x402 and EIP-8004.

The Year Ahead: Forecasts from our Investment Team "Crypto will become a building block for better AI products.” 1kx Research Partner @_weidai shares his POV: There has been a lot of hype surrounding the intersection of crypto and AI, and there is significant value in

People who cared about communication privacy used to sign PGP keys in person. Today, end-to-end encrypted messaging is just a few taps away on most messaging apps. That's the shift from cypherpunk to pragmatism that needs to happen for crypto privacy. twitter.com/_weidai/status/201...

No, you cannot achieve all three properties at the same time. That's the entire point of the onchain privacy trilemma. If there are no retroactive decryption mechanisms or velocity controls, which is Aztec's position based on my understanding, the protocol will empower anyone indiscriminately, including illicit actors, and hence not threat-resistant as defined in the trilemma. More than happy to debate on this @Zac_Aztec. twitter.com/_weidai/status/201...

New white paper from Predicate and @inconetwork: Navigating Privacy and Compliance in Blockchain Systems We map the major privacy approaches in use onchain today, show where compliance enforcement fits in, and highlight real-world deployments shaping the space.
