Chainlink - The Basics

NEED DESCRIPTION

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]. For more details on the oracle problem click HERE.

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] For an in depth look at smart contracts click HERE.

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] For an in depth look at Oracles, nodes & DONs click HERE.

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. For an in depth look at the Chainlink token click HERE.

-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). In addition, Node operatore s will use LINK tokens in order to be elegible to service specific requests. This is commonly referred to as "Staking".
+LINK is the native token of the Chainlink platform.
