Datum is a cross-chain permissionless oracle protocol for your smart contracts built on top of Optimism's newly created OP stack chains and Superchain.
Smart Contracts needs Off-Chain data to build useful applications and data availability is an integral part of any Op stack Chain. With DATUM , now you can get off chain data from Chainlink and UMA oracles straight to your chains in seconds and minimal setup of Oracle Nodes.
There are endless possiblities of dApps which can be built with the help of Data provided oracles like Predictions Markets , Insurance Claims , DEFI Appilcations and a lot more.
We are Supporting 5 types of Oracles currently :-
Price Oracles - Get price info on chain with Chainlink Price Feeds for multiple coin pairs.
VRF - Verifiable randomness with Chainlink VRFv2 , to get random words and uints to build lottery applications and other purposes
Optimistic Oracle V2 - Off Chain data like prices , YES OR NO queries , Valuations and indexes and lot more
Optimistic Oracle V3 - The OOV3 is an oracle for arbitrary off-chain data which leverages an interactive escalation game between asserters and disputers and is secured by economic incentives.
API Oracle - Any sort of API GET calls , to fetch off chain data, like Sports and Weather info directly on Chain.
The Data is obtained in a decentralized manner via Chainlink's Oracle network and UMA's system.
More information about the contracts and their usage can be found in our docs: https://datum.gitbook.io/datum/
