Ceramic Protocol

Ceramic is a decentralized event streaming protocol that enables developers to build decentralized databases, distributed compute pipelines, and authenticated data feeds, etc. Ceramic nodes can subscribe to subsets of streams forgoing the need of a global network state. This makes Ceramic an eventually consistent system (as opposed to strongly consistent like L1 blockchains), enabling web scale applications to be built reliably.

Core Components

The Ceramic protocol consists of the following components:
