An engineer from Ant Group named Chen Cheng reverse-engineered Claude Code 2.1.81 and discovered that its tool invocation requires passing through a four-layer decision pipeline to ensure safety review. The classifier design prioritizes cost and latency, monitors multiple risk categories, and includes allowlist exceptions and circuit breaker mechanisms. Meanwhile, the frequency of behavioral prompt injection is finely controlled to ensure efficiency and stability.

Ant Group engineer Chen Cheng reverse-engineered Claude Code 2.1.81 source code, revealing its Auto Mode decision-making mechanism. This mechanism employs a four-layer decision pipeline to determine tool invocations, only calling an independent AI classifier for security review when the first three layers cannot make a determination. The classifier design focuses on risk monitoring, featuring a circuit breaker mechanism and behavior prompt injection frequency controls.

The Ethereum Foundation released a quantum-safe roadmap, planning to introduce quantum-resistant mechanisms through a hard fork before 2029 to address the threat quantum computing poses to blockchain encryption. This upgrade includes optimizing public key support and enhancing layer 2 network security to ensure long-term security. The risk of quantum computing breaking existing encryption algorithms has already drawn attention from the Bitcoin ecosystem and institutions.

A community of more than 3,000 members is applying to ICANN for the .agent top-level domain, advocating for community governance of this naming layer. Participants include Brave and numerous well-known companies, with the goal of ensuring transparent registration policies and pricing. ICANN's application window will open in April 2026.

Ethereum Foundation releases new roadmap, planning to address quantum computing threats through four hard forks by 2029. Upgrades include providing quantum-safe public keys, reducing Gas fees for related signatures, and protecting Layer 2 networks. Testing of quantum-safe features launched in March.
