Confium Transparency

Stand up a local RFC 6962 transparency log, append an entry, and produce a verifiable inclusion proof — in 5 minutes.

1. 1

   Install

   cargo install --locked confium-cli

   cargo install --locked confium-cli
   confium --version

2. 2

   Start a local log

   Run an RFC 6962 log server in the background.

   confium transparency serve \\
       --data ./log.db \\
       --port 7878 &
   # Log server is now running on localhost:7878

3. 3

   Append an entry

   Add an artifact hash to the log.

   confium transparency append \\
       --artifact-hash sha256:$(printf "hello" | sha256sum | cut -d' ' -f1) \\
       --url http://localhost:7878
   # → appended at sequence 0

4. 4

   Prove inclusion

   Generate an inclusion proof for a specific entry.

   confium transparency prove \\
       --seq 0 \\
       --url http://localhost:7878 \\
       --out ./proof.json
   # → inclusion proof written to ./proof.json

5. 5

   Verify

   Verify the proof against the tree head.

   confium transparency verify \\
       --proof ./proof.json \\
       --root <(confium transparency root --url http://localhost:7878)
   # → valid
