+**Date:** 2021-12-09
+ +# Summary +Add experimental checkpoint support. + +# Description +Sigsum collaborated on a common + [checkpoint format](https://github.com/google/trillian-examples/tree/master/formats/log) +a while back. A checkpoint is basically a cosigned tree head. + +The current decision is to add experimental support for checkpoints. There is +no formal decision to adopt the above checkpoint yet, hence _experimental_. + +To keep it simple: +1. Don't add any timestamp extension. +2. Only serve the most recent tree head as a checkpoint. This allows us to +experiment with external feeders and distributors that are not part of the log. -- cgit v1.2.3
