Trillian is a transparent, cryptographically verifiable append-only data store built on Merkle trees, backed by scalable storage like MySQL. It serves as the core engine for transparency applications such as Certificate Transparency, with application-specific 'personalities' built on top.
Use cases
- run a certificate transparency log
- build an append-only tamper-evident log
- store data with cryptographic audit proofs
- implement a verifiable transparency application
- serve inclusion proofs for large datasets
When to choose
- you need a scalable, cryptographically verifiable append-only log
- you are building a Certificate Transparency personality
- you need Merkle-tree-based audit proofs over large datasets
When to avoid
- you are starting a new transparency log project (prefer Tessera)
- you need a general-purpose mutable database
- you need a small-scale log without verifiability requirements
