Offchain Components

• Validators read data from different sources, also known as origins - i.e. where the data originates from. Those sources can be both onchain and offchain. Validators then apply a data model to the raw data to calculate a final price that is resistant to market manipulation. The validators interact with each other during the Schnorr signing session.

• Challenger is an offchain component that listens to Oracle’s updates and makes sure that no invalid optimistic update is made. Thus we can be sure that our Optimistic Oracles are functioning properly. Both challengers and relays are permissionless jobs with challengers even getting paid for their effort. Participation from the community is both encouraged and supported.

• Origins are the data sources about the asset prices that can exist on-chain (DEX) such as UniSwap, dYdX, Balancer, etc. or be offchain from CEXs ( e.g. Kraken, Binance, Coinbase).

• Relays actively listen to the peer-to-peer network (the Transport Layer) and create EVM transactions out of these messages. Subsequently, these EVM transactions are recorded onchain.

• Archiver aggregates the messages created by Validators and stores it in a database. It collect all signed messages, not the intermediate messages like used for MuSig creating.

• Dashboard: The chroniclelabs.org queries the archiver to present the prices on its dashboard. You can find all of our current Oracles here
