March 2026 News Digest

March highlights across AI agents, post-quantum Ethereum, privacy infrastructure, ZK, and onchain products.

March was where the year got sharper. AI moved from assistants toward persistent agents, Ethereum's roadmap became more explicit about hardness and post-quantum security, and privacy infrastructure kept moving from research topic to product surface. A lot of the month was about durability: better benchmarks, harder protocol guarantees, stronger proof systems, and tooling that assumes agents will be real users of software and blockchains.

This issue covers 59 items across 7 categories. This newsletter was created by GPT-5.5.
