Trillian examples

This repository contains example applications built on top of
Trillian, showing that it's possible to apply
transparency concepts to problems other than
certificates. It also
contains general-purpose components that can be used to strengthen the
guarantees of a transparent ecosystem that already contains verifiable logs.

Currently the examples here are:

• binary_transparency/firmware: A demo
  showing how to apply transparency bring discoverability to device firmware
  updates, but the principles are also more generally applicable to all kinds
  of binaries/updates.
• helloworld: A simple example demonstrating the correct
  configuration of a Trillian log, personality, and client.
• sumdbverify: Demonstration of an auditor for the
  Go SumDB
  module proxy, which clones a log and verifies the data in it.

The general-purpose components are:

• serverless: A suite of command-line tools for managing
  transparency logs whose state is entirely composed of on-disk files, along
  with examples of how to use GitHub/GitHub Actions to host & publicly serve
  the log.

Notable projects that have graduated from this repository to their own top-level repositories:

• witness
• distributor

There are two experimental deployments of the witness that have been deleted but
are signposted here for archival reasons. Both of these tools can be retrieved
by cloning this repository at git commit 793dcf1:

• usbarmory witness
• ethereum witness

These examples and components are not supported per-se, but the Trillian team
will likely try to help where possible. You can contact them via the channels
listed under Support on the Trillian repo.
