The Oracle Problem?
What is the oracle problem?
The oracle problem is the challenge of connecting smart contracts to off-chain resources. This oracle problem exists for every blockchain network and smart contract platform[1] because they are inherently disconnected from the outside world.[2] The lack of connectivity between blockchains and off-chain systems is commonly referred to as the “oracle problem"[2].

Smart Contracts
What are smart contracts?
Smart contracts are tamper-proof programs that reside on blockchains and that facilitate automatic transactions by using conditional software logic such as, “if x is true, then execute y.”[3]

Oracles, Nodes & DONs
What are oracles, nodes & DONs?
The core purpose of oracles, nodes and DONs (Decentralized Oracle Networks) is to derive truth about the validity of off-chain data, events, or computation and then relay the results on-chain.[4]

The Link Token
What are LINK tokens?
LINK is the native token of the Chainlink platform. LINK tokens are utility tokens that are used to pay Chainlink node operators for their oracle services (on-chain data aggregation and submission & off-chain computation services). In addition, Node operators will use LINK tokens as a form of collateral in order to be elegible to service specific job requests.
