- Light Client Protocol
- =====================
-
- Light clients are an important part of the complete blockchain system
- for most applications. Tendermint provides unique speed and security
- properties for light client applications.
-
- See our developing `light-client
- repository <https://github.com/tendermint/light-client>`__.
-
- Overview
- --------
-
- The objective of the light client protocol is to get a
- `commit <./validators.html#committing-a-block>`__ for a recent
- `block hash <./block-structure.html#block-hash>`__ where the commit
- includes a majority of signatures from the last known validator set.
- From there, all the application state is verifiable with `merkle
- proofs <./merkle.html#iavl-tree>`__.
-
- Properties
- ----------
-
- - You get the full collateralized security benefits of Tendermint; No
- need to wait for confirmations.
- - You get the full speed benefits of Tendermint; transactions commit
- instantly.
- - You can get the most recent version of the application state
- non-interactively (without committing anything to the blockchain).
- For example, this means that you can get the most recent value of a
- name from the name-registry without worrying about fork censorship
- attacks, without posting a commit and waiting for confirmations. It's
- fast, secure, and free!
