What is Chainlink (LINK)? Buy Chainlink on CoinJar: Chainlink is a cryptocurrency that plays a crucial role in the world of decentralized finance (DeFi). In this article, we explain what Chainlink is, how to buy it, and what it is used for.
Chainlink is a decentralized oracle network that bridges the gap between smart contracts and real-world data.
But what on earth does that mean?
Smart contracts on blockchains can’t access external data directly. Chainlink solves this problem by providing a decentralized network of oracles.
These oracles gather real-world data (such as stock prices, weather conditions, or sports scores) and feed it into smart contracts.
Imagine a smart contract that triggers a payment when a specific event occurs (e.g., a flight delay). To execute this, the contract needs accurate external data. Oracles act as trusted intermediaries, ensuring that smart contracts receive reliable information. This makes it a good solution for DeFi applications.
The oracle problem arises because smart contracts cannot directly access external data. Chainlink addresses this by creating an incentive system for oracles. These oracles provide reliable data, gain a positive reputation, and are rewarded with LINK tokens. As they accumulate reputation, their accuracy and reliability increase.
LINK has gained growing attention since its introduction in September 2017. Here are some factors to consider.
The technology is actively used by various projects, including DeFi platforms, gaming, and supply chain management.
The white paper outlines its purpose and technical details. It’s essential reading for potential investors.

As blockchain networks expand, the need for reliable oracles grows. Chainlink decentralises this critical service.
Keep an eye on the circulating supply of LINK tokens. Scarcity can impact its value.
Chainlink’s decentralised oracle network addresses a fundamental problem in blockchain-based smart contracts. While no investment is risk-free, LINK’s strong fundamentals make it an interesting choice for those interested in DeFi and real-world data integration.
