Hi, I'm Martin. I'm a software engineer working on transparency. I'm a core maintainer of Google Certificate Tranparency logs, Trillian, and many of the libraries under transparency-dev.

I'm the author of the Claimant Model, which is a framework for understanding and communicating about transparency solutions.

My current focus is delivering a common log witness that can be easily deployed. This is the armored witness, a hardware device that uses secure boot to provide a tamper-proof witness solution. This uses the checkpoint distributor as a way to make available the witnessed checkpoints.
