Chainlink - The basics

A brief description of......goes here.

The oracle problem?

What is the oracle problem? The oracle problem is the challenge of connecting smart contracts to off-chain resources due to the inherent security properties of the blockchain. This oracle problem exists for every blockchain network and smart contract platform. 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.” For an in depth look at smart contracts click HERE.

The Link token

LINK tokens are utility tokens used to pay 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.

Staking

What is staking within the Chainlink ecosystem? 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.” For an in depth look at Chainlink staking click HERE.

Chainlink specific contracts

• Market & data feed speific contracts. We've broken the history out into contract-based milestones.
  • Direct Request / Runlog (DR)
  • Flux Monitor (FM)
  • Offchain Reporting (OCR)
  • (what could be next)

• Keeper contracts.

• VRF contracts.
