What Is Chainlink (LINK)?

As the blockchain technology widens its use cases and influence, the problem of seamlessly combining it with the real-world data stands out more clearly. Chainlink is a project that aims to solve this issue. How? Let’s find out together in this article!

What Is Chainlink?

Chainlink is a decentralized oracle network that connects blockchains to external data, that is, basically allowing smart contracts to access real-world information. Launched in 2019 by Sergey Nazarov, Steve Ellis, and Ari Juels, it is currently managed by Chainlink Labs — a U.S.-based company with a truly global footprint, leveraging a decentralized network of nodes worldwide. The network solves the “oracle problem” — a challenge of getting data from outside of the blockchain and also keeping everything secure. This is a life-savior for DeFi, dApps, and many other projects that need real-time updates on things like weather, sports scores, or financial market movements.

Chainlink operates using its native token, LINK, which is central to the project’s ecosystem. LINK is an ERC-20 token, allowing it to integrate efficiently within the broader Ethereum ecosystem. There’s a total supply of 1 billion LINK tokens, with almost 700 million already in circulation.

How Does Chainlink Work?

Chainlink is a completely decentralized oracle network; it relies on a community of independent node operators. Those operators gather and attentively verify off-chain information and then get paid in LINK tokens for it. So, Chainlink is basically a third-party between real-world data and smart contracts on the blockchain and node operators are the bricks of this bridge.

Chainlink makes money by charging fees for its oracle services, so companies and platforms pay to access its decentralized data. The network has active partnerships with big companies like SWIFT, Mastercard, and UBS, bringing blockchain into traditional finance. Chainlink further enables tokenized assets to be traded and settled across various blockchains, closing the gap between the traditional financial system and the cryptocurrency world.

LINK is also used for staking: holders can lock up their tokens to help secure the network and earn rewards. However, Chainlink doesn’t actually use Proof-of-Stake (PoS) for its consensus. Instead, it operates on a staking model within its own network.

Pros And Cons Of LINK

To help you evaluate the role of Chainlink and its token, we’ve gathered all their pros and cons in one table:

Should You Invest In Chainlink?

Chainlink is very well positioned in the blockchain sector and can fuel further development for DeFi and NFTs. Moreover, active partnerships with big-name companies confirm that traditional finance is ready to engage with blockchain tech for good, which adds to its long-term potential. Another plus is that staking LINK and receiving rewards for it allows one to earn passive income on the side. Additionally, Chainlink stands out thanks to its strong liquidity — you’ll find LINK available on major platforms like Cryptomus. High trading volume means investors can trade LINK efficiently, without worrying too much about slippage or delays. In practical terms, it’s simply more accessible, which definitely adds to its appeal as an investment.

Speaking of risks, LINK, being a crypto, is highly volatile. Its price may undergo huge swings, which makes it a speculative investment at its core. Also, there is a competition: other blockchain oracles, such as Band protocol or API3, are gaining traction and finding their own audiences, which perhaps could prove to challenge Chainlink's dominance. Then, of course, Chainlink depends on Ethereum with its high gas fees and scalability troubles.

Although the project has convincing use cases and institutional backing, whether it can keep up in the race owing to mounting competition and network challenges will determine its fate. Like any investment, it's important to do your own research and think carefully about how it fits into your overall strategy.
