The importance of Chainlink

The first thing to note about ChainLink is that it is a Blockchain project that simply focuses on building bridges between payment services such as Visa and PayPal, banks such as Wells Fargo and blockchains such as Bitcoin and Ethereum.

The network was established in the year 2015, and its ERC-20 Link tokens were given to the public at an ICO token sale back in 2017.

At first, ChainLink was named SmartContract, and its major aim is to bridge the gap between legacy systems and Blockchain effectively.

All About ChainLink Network

Simply put, ChainLink is a platform that attempts to close the gap between real-world applications and smart contracts positioned on the Blockchain. And, this frequently tends to be off the Blockchain.

ChainLink's Cryptocurrency makes use of Oracles which discovers and validate real-world information and brings it on the chain to be merged into smart contracts.

ChainLink has a Cryptocurrency known as LINK. This is the virtual token created natively as a part of the ChainLink platform, and it is also an ERC20 token that helps in facilitating user’s usage of ChainLink.

Once information is validated by the nodes of the ChainLink network, they are paid in terms of LINK coins.

The ChainLink platform is actually a Blockchain-based solution that tries to apply the benefits of Blockchain smart contracts to more than mere on-chain data.

How ChainLink Works

As the platform that attempts to bridge the wide gap between off-chain data and business and on-chain smart contracts, ChainLink has two primary architectural components, which are:

  On-chain infrastructure, and;

  Off-chain infrastructure

For the on-chain infrastructure, it comprises of on-chain contracts that are deployed on the Blockchain of Ethereum. These are the Oracle contracts that process the data requests of every user that wishes to access the data that are off-chain

The users who want information from off the Blockchain community must submit a request contract to the network of ChainLink, and in turn, the request will be processed into its very own contracts.

This matches the user’s contract to the already existing Oracles that are needed for the application. The contracts comprise of:

  Oracle Selection

The contract of the user contains an SLA; Service Level Agreement that specifies major parameters as well as demands for the user’s data search. Also, this may include specifics of the data needed, the number of resources needed, and reputation of the Oracle.

Meanwhile, the user can make use of filters and search manually for the available Oracles. ChainLink also offers am automated matching engine in which Oracles are based on the SLA whenever a manual search is not feasible.

  Data Reporting

The chosen off-chain Oracles execute the service agreement mentioned in the contract of the user and transmit the data to the blockchain for the on-chain nodes to begin processing.

  Result Aggregation

An aggregating contract is effectively utilized to collect the data that has been submitted by the Oracles, and it balances all of the data to offer the user with accurate data. This is a necessary step to make sure of data integrity.

For the off-chain infrastructure, it comprises of Oracle nodes that are linked to the Ethereum system. It collects the data requested by the user from off-chain resources.

Here, the data that has been received is processed via the ChainLink’s core. This is the software that enables the communication between the Blockchain and the off-chain infrastructure.

However, in return for their contribution to the system harvesting and transmission of data, off-chain Oracle operators are incentivized in the form of LINK; the ERC20 token of ChainLink.

Furthermore, off-chain nodes enable developers to merge external adapters, which are the plugins that the operators use in accommodating other programs to their operations.

Presently, ChainLink only interfaces with smart contracts on the Blockchain of Ethereum, although it aims to work with diverse networks in the nearest future.

To resolve these problems associated with a centralized Oracle network that can be tampered with, ChainLink makes use of a source and Oracle distribution. This means that it makes use or diverse Oracles to collect data for a distinct user contract and in turn, these Oracles are expected to utilize diverse resources for their data collection.

Importance Of ChainLink To Cryptocurrency

Some of its importance to virtual currencies include:

  ChainLink is effectively resilience to the bear market even as the entire Cryptocurrency market has shown how depressed they can be as a result of issues that occurred in the last few months. Its token price always finds a way to avoid a huge downfall

  Its decentralized Oracle service is a unique concept, and it combines the long-cherished aims of promoting the interoperability of Blockchain as it puts ChainLink on the map when it comes down to Cryptocurrency projects

Benefits Of ChainLink To Other Institutions

Its benefits to other institutions asides from virtual currencies include:

  It serves as an avenue where businesses can thrive

Since information has been taken to be the bedrock of any organization or business, operating a business demands the relay of vital information as well as data. ChainLink can, however, be the decentralized platform where businesses effectively thrive.

This is because it can aid both the old and new businesses who most times find it complex to access first-class info easily. Both businesses and people can make use of their Oracle network via APIs to bridge this gap between outside information and investment or business in the ChainLink Network.

  User-friendly environment for its operators

While understanding the concept of ChainLink via its white paper and reviews may be quite abstract to most people. However, the platform and environment have been built with a very simple interface as well as architectural design.

  Promising future for investors

Though it is live as a testnet, all of its promises have assisted in keeping hope alive. Its creators have been capable of partnering with some big players in diverse industries like OpenLaw, Polkadot, Swift network, etc.

This simply implies that there is a whole lot that the future holds for both investors and ChainLink.

Link Token

Its sale was capped at about thirty-two million dollars plus an overall supply of one billion LINK tokens.

Judging from the statement of its developers, thirty-five percent of all LINK tokens will go to the operators of the node to incentivize the immunity with an extra thirty-five percent sold during the public token sale.

As for the final thirty percent of the overall LINK tokens, it will stay at the company for the sake of staff payments and continuous development.


For platforms like Ethereum, they will enable users to only link and use the data stored on its very own Blockchain, but for ChainLink, it attempts to break this mold with its acceptance of off-chain data.

Through its provision of a Decentralized Oracle service, ChainLink has set out to revolutionize the way smart contracts are used effectively.
