The services in Lita's offering include but are not limited to those services depicted in the above diagram.

1. Your application generates some facts, which the Lita prover service proves.
2. The succinct proofs of many facts, potentially for many different applications, are further compressed by the Lita proof aggregator. The result is a single proof, which proves a set of potentially unrelated facts.
3. The compressed proof of a set of facts is posted to the settlement layer. The settlement layer is a trusted computing environment, such as a layer 1 blockchain, which verifies the proof and makes a timestamped record of the facts. This act of settlement provides convincing evidence that those facts proven were known as of the block time when their proof was posted.
4. Your application can then use the settlement layer as a witness to the facts being true. This pattern of interaction allows for trustless, or low trust assumption, interactions between your application's users, to satisfy a diverse set of use cases.
