Chainlink is a decentralized oracle network that connects blockchains to real-world datasets. For more understanding, we will talk about the topic of "What is a Chainlink? How does a Chainlink work?"
What is a Chainlink?
Chainlink, is a decentralized blockchain oracle network that enables smart contracts to communicate securely with real-world data and services outside of blockchain networks.
Although blockchain is great at what it does — providing a decentralized, secure ledger for digital transactions — it isn't so great at taking input for things happening outside the blockchain. There are many “off-chain” forces that influence markets, including fiat currencies, credit cards, and even the weather and sports scores. As a decentralized oracle, Chainlink can provide input to what's known as smart contracts.
The Chainlink blockchain is hosted on the Ethereum platform, which uses the proof-of-stake operating protocol. In addition, Chainlink is an open-source blockchain project, meaning anyone can view the project's code and contribute.
How does it work?
Chainlink is a decentralized oracle network consisting of purchasers and providers of data. Purchasers request data and providers return data in a secure way.
Purchasers select the data they want and providers bid to provide that data. Providers must commit a stake of LINK tokens when they make a bid, which can be taken away if they misbehave. Once providers are selected, it is their job to bring the correct answers on chain.
Chainlink uses an oracle reputation system to aggregate and weight the data provided. If everything goes smoothly, providers get paid and everyone is happy.
