What Is Chainlink (LINK)?


Smart contracts are agreements written in code that automatically execute when certain conditions are met. These contracts bring trust, security, and reliability to the world of digital transactions. But they require a reliable connection to data sources in order to verify the conditions of the agreement. That’s where Chainlink (LINK) comes in.

What Is Chainlink (LINK)?

Chainlink is an open-source network of decentralized oracles that allow smart contracts on different blockchains to securely access off-chain data feeds, web APIs, and traditional bank payments. It does this by providing data from multiple sources and formats, so users can be sure their information is accurate and up-to-date. Through its network of secure nodes, developers can easily create two-way communication between blockchain-based smart contracts and the outside world.

Think of it this way, without Chainlink, smart contracts are like a computer that can process information but can’t access it. It would be stuck inside its own little world, unable to get the data needed to operate effectively and efficiently. That’s where Chainlink comes in. It acts as the bridge between these two worlds – the blockchain and the real world. To explain this better, let’s dive into how chainlink actually works.

How Does Chainlink Work?

Chainlink works by connecting two decentralized networks, one on-chain and one off-chain. On the blockchain side, it provides nodes that communicate with each other to verify events or conditions have been met in a smart contract.

On the off-chain side, Chainlink has data feeds that provide information about real-world events and prices of assets like Bitcoin or USD/EUR exchange rates. These data feeds can be used to trigger a payment when certain conditions are met, for example if the price of Bitcoin reaches a certain level.

In summary, chainlink literally acts as a link between oracles, providing data from off-chain sources to on-chain sources and vice versa. It allows smart cotracts to access real world information that exists outside of the blockchain in a secure manner.

The History Of Chainlink

Chainlink was founded in June 2017 by Steve Ellis and Sergey Nazarov and officially launched in May 2019. It was envisioned as a blockchain-based platform to power secure and reliable connections between smart contracts and the real world. It was built on the Ethereum blockchain, and its main purpose is to provide a safe and secure way for smart contracts to access external data and bank payments without relying on a single oracle provider.

The Chainlink network has since grown significantly, and now seeks to expand with the introduction of Chainlink 2.0, a protocol that is designed to further enhance the security and reliability of data sources for smart contracts.
