You must be aware of a few popular blockchain networks in the world like Ethereum network, Bitcoin technology, etc. but in the recent times, the smart contracts technology has advanced a lot and there are several new cryptocurrency networks which make it easier to build decentralized apps and make the transactions both quick and efficient.

Chainlink is one such secure blockchain middleware which was launched by the San Francisco Fintech company SmartContract.

This blockchain middleware ensures that smart contracts can connect with each other all across the blockchain by allowing them to access major off-chain resources like web APIs, bank account payments, and data feeds.

The Chainlink system circles completely around the LINK network and tokens. So, let’s learn more about this latest blockchain network which is utilizing Oracle network to connect its smart contracts.

Quick Navigation:

What is Chainlink Network?

As mentioned earlier, Chainlink is a secure blockchain middleware which lets the smart contracts from all over the network to connect along with the essential resources that they need in order to be useful.

Chainlink creates secure oracles for platforms like Bitcoin and Ethereum so that the smart contracts are connected on several networks to crucial external data feeds to trigger the off-chain systems operations.

The LINK Network is known to be the initial decentralized oracle network which allows everyone to securely and safely supply smart contracts with the access to major external data, API capabilities, and several off-chain payment capabilities.

Basically, anyone who possess data feed, or offers beneficial off-chain payment services like local payments, or other types of API capabilities can supply these services directly to the smart contracts in return for LINK tokens.

You can become a Chainlink Node operator to provide your data, payment, and other online services directly to a smart contract.

Chainlink creates a decentralized system for smart contracts to directly access important off-chain data and uses a scalable, auditable, and secure way to add APIs, off-chain payments, and data feeds into a smart contract.

Team Behind Chainlink

Chainlink team consists of only two members: Sergey Nazarov and Steve Ellis. Both of these Chainlink team members founded the network in 2017 and played a major role in its success and improvement of Chainlink network.

Sergey Nazarov is the CEO of the Chainlink organization and has a great background in the blockchain technology. He previously founded Security Asset Exchange which was an exchange network that worked as a decentralized email service.

Steve Ellis is the CTO of the Chainlink organization and has previously worked with Sergey on Security Asset Exchange and also worked in the Pivotal Labs as an experienced software engineer.

Apart from these two founders, Chainlink consists of an advisory team which includes some members from the Ethereum foundation, and professors from Cornell Tech and the University of Illinois.

What are LINK tokens?

The LINK token was introduced to pay the Node operators on the Chainlink network to perform off-chain services. The LINK token can not only be used to pay the Chainlink node operators but is also employed for paying data providers, payment provides, and several other online providers for all the online services performed by them.

So, smart contract users can use the LINK tokens in order to pay the services provided by the data providers and this is important because a huge majority of smart contracts need external data for implementation.

It is really tough to get the data from external sources which is why Chainlink’s token system will help in getting accurate data while ensuring that the Chainlink network grows into a decentralized network.

Since the LINK tokens are used as a digital currency on the Chainlink network, the value of the LINK tokens will increase as the usage of Chainlink network increases.
