What is Chainlink?

Chainlink is a decentralized oracle network built on the Ethereum blockchain network, founded by CEO Sergey Nazarov.

Simply, ChainLink is a Decentralized Network of nodes that offer data from off-blockchain sources to on-blockchain smart contracts via Oracles. This process, along with extra secure hardware, eliminates the reliability issues that might occur if using only a single centralized source.

History of Chainlink

In the 2014 year, SmartContract.com was founded as the best way to get external data onto the blockchain network. From this foundation, Chainlink was born and implementing smart contracts to connect to particular data feeds from any API or data source. This was a perfect and great innovative game-changer for the blockchain industry.

After increasing $32 million in an ICO, the Chainlink mainnet (blockchain protocol is completely developed and delivered, meaning that cryptocurrency transactions are being broadcasted, verified, and recorded on a distributed ledger technology) went live in June 2019 year. The Chainlink business project has become a pillar in the oracle network space, and a must-have for all credible Decentralized finance (DeFi) projects.

What are Smart Contracts?

Smart contracts permit cryptocurrencies from one address to be moved to another address when specific conditions are met. Publicly viewable on the blockchain, smart contracts are immutable, meaning that the parameters of an agreement or the specifics of a contract cannot be altered once deployed.

Smart contracts that require off-chain information must have a reliable medium for getting the data on-chain securely and translating it perfectly, before translating any on-chain data back to any off-chain parties.

This kind of communication problem has held back smart contract development but with the introduction of oracles, this issue is now a thing of the past scenario. Smart contracts can be used for an assembly of use cases sector-wide.

Oracles

Oracles are used to get real-world data onto the blockchain network through smart contracts. This could be anything from weather forecast data, price feed data, or the result of a cricket match. 

Decentralized finance (DeFi) is the most familiar use case for oracles, as these kinds of business platforms require the most accurate and reliable data mediums available to prevent disaster.

Features of Chainlink Blockchain Platform

The ChainLink is actually a decentralized oracle network, that verifies and connects the blockchain network with the real-world data. By doing so, this develops the smart contract functionality to work with another blockchain network using an external adaptor. 

This kind of activity can be executed on any blockchain network platform, which has covered way for smart contracts for fiat currencies, credit cards, or any other data. Its the main advantage of the ChainLink solution. ChainLink blockchain features are listed below.

Investing In Chainlink – BlockchainAppsdeveloper

all crypto entrepreneurs who have watched the cryptocurrency charts as of late can speak on the high popularity of Chainlink (LINK) (Market Cap Rank #5). This popularity stems from a variety of various mediums including the companies unique business concept.

What issues Does Chainlink (LINK) Solve?

Chainlink attempts to rectify one of the main issues facing the blockchain network sector, how to transact information to and from the blockchain network. Conventionally, this kind of attempt is skilled by sensors called oracles. Actually, as I mentioned before Oracles can be set up to monitor nearly any kind of data and transactions. simply oracles that monitor the price chart, weather report, sports scores, account balances, and the value of stocks, and more.

Oracles Expand the Usability of Blockchains 

It provides a reliable way to implement smart contracts when the terms and outside parameters are met. but, oracles are a centralized concept. This centralization creates them the weakest spot in the blockchain network. If an oracle becomes corrupted, it puts the complete network at-risk zone.

Data entry is the main important step in blockchain development. We all are well known about, blockchains are immutable and censorship-resistant method. If the certain information they receive is incorrect, it’s very difficult to change, delete or modify, and rectify this information. In simple words, it’s impossible. This kind of problem is known in the development community called the “Oracle Problem.” Chainlink blockchain solution attempts to tackle these issues through the integration of various next-gen blockchain protocols.

A Quick Recap on Smart Contracts and Oracles:

Smart contracts are immutable concepts and verifiable contracts that instantly implement in an IF/THEN framework when terms and conditions are met.

The certain data that defines these terms and conditions has conventionally come from the blockchain network.

A few days before, oracles have been introduced into the cryptocurrency ecosystem to bring off-chain data to on-chain smart contracts.

But, centralized oracles decrease the advantages of on-blockchain smart contracts because they may be untrustworthy manner.

How Does Chainlink (LINK) Work?

Chainlink - World’s first blockchain oracle network. An oracle network would be able to leverage the same technologies that appear in traditional blockchains to ensure that the blockchain nodes in operations are functioning and data properly.

Chainlink Ecosystem, this process develops when a customer puts out a Requesting Contract for data. This notification will appear and list as a blockchain event within the blockchain network. This listing will then develop a Chainlink Service Level Agreement (SLA) Contract. 

Chainlink Service Level Agreement (SLA) Contract also launches 3 contracts in the blockchain network system.

Chainlink Reputation Contract - Its 1st contract and It verifies an oracle’s authenticity. Its coding will review every oracle history. The entire system looks at the past participations of this oracle network and how accurate they were. At the end of the conclusion, the oracle receives a certain rank. This rank supports the entire system to easily utilize the best oracle networks.

Chainlink Order-Matching Contract - The 2nd contract deploys the Requesting Contract to the Chainlink nodes. When the nodes receive this kind of proposal, they will automatically start to bid on it. The complete system instantly configures the number of nodes and the node type required to complete the request using preprogrammed preconditions.

Chainlink Aggregating Contract - The 3rd one contract pacifies incorrect information. The complete system will review all the information that has completed the previous checks  & balances. Any information that doesn’t fall in line with the other blockchain network inputs is ignored. Once this step is finished, the data is automatically validated and available to the blockchain network.

Advantages of Chainlink (LINK)

Chainlink brings some major advantages to the Blockchain network. 

Oracles are very important to network expansion. They are at the main core of some most exciting developments in the blockchain network sector. For instance, DEXs (decentralized exchanges) utilize oracles to determine the cost of cryptocurrencies without proving an order book status.

Chainlink also permits firms to proceed to leverage this powerful tech in a trustless manner. Customers can rest assured that the information they receive is not incorrect & timely. In the event of a single node failure zone, the entire network system instantly replaces it with a higher ranking alternative.
