Martin Hutchinson

Senior Software Engineer @ Google • Transparency Solutions

I'm a software engineer living near Edinburgh, UK, working on transparency solutions and cryptographically verifiable logs.

I am a core maintainer of Tessera, TesseraCT, Google Certificate Transparency logs, Trillian, and open-source libraries across transparency-dev. I also author and maintain C2SP transparency specifications.

Core Focus & Projects
Tessera & TesseraCT → transparency-dev

High-throughput, tile-based transparency log engine powering modern verifiable logs and supporting Merkle Tree Certificates (MTCs), alongside TesseraCT for Static CT APIs.

Go Static CT Merkle Trees
Verifiable Index (VIndex) → transparency-dev/incubator

High-performance, cryptographically verifiable indexing for transparency logs. Solves the efficiency-verifiability trade-off by enabling fast, targeted lookups with cryptographic proof of completeness.

The Claimant Model → Architecture Framework

Author of the conceptual framework for understanding, evaluating, and communicating security and trust properties of verifiable transparency systems.

System Design Security Verifiable Logs
Woodpecker → mhutchinson/woodpecker

An interactive terminal UI (TUI) tool for inspecting Transparency Logs (including Static CT logs), verifying inclusion proofs, and inspecting leaf entries.

TUI Go CT Inspector

Key verifiable log infrastructure including log witnesses, checkpoint distributors, and the armored witness — a tamper-proof hardware witness built on secure boot.
