What is a blockchain Oracle?

Blockchain oracles are entities that connect blockchains to external systems, thereby enabling smart contracts to execute based upon inputs and outputs from the real world. Oracles provide a way for the decentralized Web3 ecosystem to access existing data sources, legacy systems, and advanced computations.

What is blockchain & how does it work?

What is Blockchain? Blockchain is defined as a ledger of decentralized data that is securely shared. Blockchain technology enables a collective group of select participants to share data. With blockchain cloud services, transactional data from multiple sources can be easily collected, integrated, and shared.

What is a cross-chain oracle?

Cross-chain oracles enable interoperability for moving both data and assets between blockchains, such as using data on one blockchain to trigger an action on another or bridging assets cross-chain so they can be used outside the native blockchain they were issued on.

What is a chainlink Oracle Network?

Chainlink's decentralized oracle network is an open-source technology infrastructure that allows any blockchain to securely connect to off-chain data and computation resources. The network nodes fetch, validate, and deliver data from multiple sources onto blockchains to execute smart contracts.
