Notes from Bob Blessing-Hartley on Web3, zero-knowledge proofs, decentralized identity, and agentic AI — written while building.
CTO, Shielded.io
I work on the Midnight Network and adjacent systems: privacy-preserving smart contracts in Compact, ZK circuit design, Substrate runtime engineering, and the identity primitives built on top. Lately I spend a lot of time on AI agents that have to reason about cryptographic protocols without making things up.
