Link Token and Chainlink Protocol

Chainlink has grown by 215 projects in 2024, to a total of over 2000 projects. Chainlink Oracle network was designed to support the creation and growth of the DeFi space. It has since become the standard go-to oracle for almost all web3 solutions.

Since its launch, Chainlink has supported over $9 trillion worth of transactions. Currently, Chainlink partners with several global financial institutions such as Swift, DTCC, and Australia & New Zealand Banking Group Limited.

Well, what makes Chainlink such a significant part of the crypto and DeFi space. Let's discuss!.

The Role of Oracles

Blockchains, by design, do not interact with external systems and external data sources directly. However, smart contracts may need external information for the execution conditions to be realized.

Consequently, data acquired from external sources needs to be brought onto the blockchain securely and reliably for proper contract execution.

This is achieved through blockchain oracles. Blockchain oracles can be described as third-party services that aid in fetching, verifying, and relaying external data into blockchain networks.

Overview of Chainlink and Oracles

Chainlink is a project that addresses the challenges of the oracle by introducing the concept of decentralized nodes, named oracles; thereby providing reliable real-world data for smart contracts.

In contrast to centralized oracles, which are prone to manipulation and create a single point of failure, Chainlink's nodes collectively fetch, verify, and relay data with increased security and trust.

What is the Link Protocol?

Chainlink protocol contains a decentralized network of nodes that fetch off-chain information and relay it to on-chain smart contracts through oracles. 

Chainlink was developed in 2017, during a period when more people were getting interested in crypto investment and opportunism. Its founders were Steve Ellis and Sergey Nazarob who had initiated the project three years earlier. 

The focus of the project was to connect smart contracts with real-time and accurate external data securely through decentralized nodes.

This system, built on the ethereum blockchain, proved its efficiency and became popular; gaining partnerships with the biggest Dapps in the DeFi space.

How Chainlink Works

Imagine you have a smart contract running on the ethereum blockchain. The smart contract can do many amazing things automatically. However, it cannot access any data outside the blockchain. The data could be news, weather data, or economics- needed for the smart contract to function.

You need a way to feed information from the outside world to your smart contract. This is where Chainlink provides you a solution; creating a bridge between the outside world and your smart contracts. 

Chainlink achieves this through a network of computers called oracles, fetching and feeding information into your smart contracts. The smart contracts then get the information to act on automatically.

The owners of the oracle (network nodes) are rewarded with $LINK (Chainlink's native token) to ensure the provided data is accurate. As several nodes are verifying data, a single point of failure does not disrupt the network.

The LINK Token

LINK is Chainlink’s native token. The token has several uses within the Chainlink network:

To participate in validation, users must have staked LINK tokens. The larger the amount staked, the more contracts the validator receives. 

The validators and other stakers earn additional LINK tokens for staking and for successfully provided data.

Also, smart contract developers looking to access data through the Chainlink oracles, pay node operators using LINK.

Sometimes Chainlink nodes offer other off-chain services such as computation and are paid using LINK tokens.

Investing in LINK Token

As the DeFi space continues to grow, Chainlink's role as bridging technology will continue expanding; enabling better automation, more transparency, and trust.

Expert crypto investors often recommend trading or investing in crypto tokens that back projects with the potential to grow. LINK may qualify as one of them.

Use Cases of Chainlink Oracles

• Decentralized Finance (DeFi)

Chainlink supports many DeFi projects; feeding the information that makes derivatives trading, lending, and borrowing possible. Popular DeFi platforms such as Aave, Compound, and Synthetix depend on Chainlink to access accurate data.

For instance, DeFi lending platforms use oracles to determine each user's borrowing capacities. Also, Chainlink oracles help with checking if a user's position is subject to liquidation.

• Insurance

Today, insurance firms use smart contracts. By providing reliable information from external sources, Chainlink helps insurance smart contracts to automatically make payouts according to preset conditions. As such the need to manually process claims is reduced.

• Real World Asset (RWA)

One of the most valued real-world assets is real estate. Chainlink oracles enable automatic verification of details of a specific property including transaction data, and ownership records. This facilitates more secure and smoother real estate transactions. As such, the risk of fraud is reduced significantly as transparency is increased in the process of selling and buying real estate properties.  

• Dynamic NFTs and Gaming

Chainlink has non-financial use cases as well such as NFTs and gaming. Some NFTs are designed to change in value, distribution, and appearance based on external occurrences such as time of day. In such a case, Chainlink feeds the information on time of day aiding smart contracts to automatically execute the changes.

Also, Chainlink oracles help generate verifiable randomness, in projects that randomly assign traits to different NFTs or randomly choose winners for an NFT drop.

Blockchain gaming also requires verifiable randomness for the creation of unpredictable and engaging experiences within the game. For example, a randomized appearance of loot boxes.

5. Supply Chain Management 

Chainlink helps with real-time tracking and verifying of products as they are moved throughout the supply chain. This ensures product authenticity, preventing fraud and increasing overall efficiency.

Benefits and Challenges of Chainlink

Benefits

Secure, Reliable Data: Chainlinks decentralization ensures the data fetched to be fed on-chain into smart contracts are tamper-proof. This enhances the security and reliability of decentralized applications (dApps).

Decentralization: Chainlink's decentralized nature eliminates the disruption of a single point of failure, enhancing the overall robustness of dApps.

Interoperability: Chainlink easily integrates with most blockchains, as such it is versatile in enabling the creation of smart contracts across many platforms.
