What is Chainlink (Link)?

Chainlink (LINK) is a decentralized oracle network that aims to bridge the gap between smart contracts on the blockchain and real-world data, external APIs, and payment systems. Smart contracts are self-executing contracts with the terms of the agreement between buyer and seller being directly written into lines of code. They are executed automatically when certain predefined conditions are met.

While smart contracts offer numerous benefits, they operate in a closed, isolated environment and cannot access data outside of the blockchain. This limitation becomes a problem when the smart contracts need to interact with real-world data, such as market prices, weather conditions, or sports results, to execute correctly.

Chainlink provides a solution by acting as a decentralized oracle network. Oracles in the context of blockchain are trusted data feeds that deliver information from outside the blockchain to the smart contracts. Chainlink facilitates this communication by connecting smart contracts with real-world data sources and APIs in a secure and reliable manner.

Here's how Chainlink works:

1.     Data Request: Smart contracts on the blockchain issue a request for external data to the Chainlink network.

2.     Oracle Node Selection: Chainlink selects appropriate oracle nodes from its network to fulfill the data request. Oracle nodes are responsible for retrieving the

required data from external sources.

3.     Data Verification: The selected oracle nodes fetch the data from various sources and verify its authenticity and accuracy.

4.     Data Aggregation: To ensure reliability, Chainlink aggregates data from multiple oracle nodes to create a single, consensus-based data point.

5.     Data Delivery: The verified and aggregated data is delivered back to the requesting smart contract on the blockchain, enabling it to execute based on the

real-world data.

The native cryptocurrency of the Chainlink network is called LINK. It serves various purposes within the ecosystem, including paying node operators for providing data, securing the network through staking, and ensuring the proper functioning of the network's economic incentives.

Chainlink aims to make smart contracts more versatile and capable of interacting with external systems in a secure and decentralized manner. This is crucial for a wide range of applications, including decentralized finance (DeFi), insurance, supply chain management, and much more.
