Currently the examples here are:
etherslurp: An app which syncs a popular blockchain into a Trillian Log, and then replays the transactions contained in the blocks into a Trillian Map of SHA256(Account ID) -> Balance.
gossip: An implementation of a Gossip Hub, which is a transparent append-only Log that is intended to hold signed material from other Logs.
registers: A tutorial for building Trillian apps showing the use of logs and maps and serving the results to clients.
These examples 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.
