Chainlink - The Basics
NEED DESCRIPTION
The Oracle Problem?
What is the oracle problem?
Blockchains are inherently disconnected from the outside world.[1]
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.[2] The lack of connectivity between blockchains and off-chain systems is commonly referred to as the “oracle problem"[1].
For more details on the oracle problem click HERE.
Smart Contracts
What are smart contracts?
Smart contracts are tamper-proof programs on blockchains 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 tokens are utility tokens used to pay Chainlink node operators for their oracle services (on-chain data aggregation and submission & off-chain computation services) and also for deposits (staking) placed by node operators as required by contract creators.
