What is Chainlink (LINK) blockchain

It's an oracle network that powers hybrid smart contracts, giving the apps the ability to access off-chain data outside their native platform. For instance, developers can use chainlink to transfer real-world data to smart contracts in a tamper-proof way that is easy to audit.

The most popular application of Chainlink involves sourcing price feed data. For instance, Solanart — an NFT Marketplace on the Solana blockchain— utilizes the Chainlink price feed data allowing it to display USD-based prices for various NFTs on sale.

There are other interesting applications, such as the provision of weather data. The platform supplies various data feeds to several blockchain networks, including Ethereum, Avalanche, Polygon, Binance Chain, and Gnosis. Developers can browse for feeds on the main website based on different categories.

Who created the Chainlink network?

Chainlink was collectively founded by Sergey Nazarov, Steve Ellis, and Ari Juels professor at Cornell Tech. There was also some input from students at Cornell University.

The three co-founders released a white paper titled "Chainlink: A Decentralized Oracle Network" on September 4th, 2017.  Sergey and Steve were already familiar with oracle networks after establishing SmartContract, a private provider of open oracle network solutions. The new project was different because it was fully decentralized. The project got its official start on May 30, 2019, following the launch of its main net, kicking off the ability of smart contracts to access external data through Chainlink’s nodes. On April 15th, 2021, the project released a new white paper for “Chainlink V2.0,” introducing the concept of hybrid smart contracts with off-chain data reporting.

What is Chainlink smart contracts?

Smart contracts are applications deployed on decentralized networks that are tamper-proof and capable of executing without interference —after specific conditions are met. The self-verification and execution nature of the contracts introduces the issue of connectivity and utilization of external data from APIs & feeds.

Chainlink attempts to solve this problem by introducing a decentralized oracle network that fosters trust when smart contracts fetch and retrieve data. The network implements both on-chain and off-chain architecture to ensure the seamless exchange of data securely. Chainlink proposes various mechanisms to foster trust, from reputation management to having distributed data providers/sources.

Advantages and disadvantages of Chainlink

The innovative blockchain technology has the following advantages:

• Allows developers to access high-quality data and premium APIs;
• Users can set up a Chainlink node locally or on a remote server, helping to keep the network decentralized;
• Developers can call any API securely from a smart contract with the Chainlink connect library;
• The technology is already proven, having helped to facilitate data connections for the leading decentralized applications such as Aave and Synthetic;
• Developers can automate their smart contracts with Chainlink Keepers

As a network Chainlink does not have a lot of weaknesses or disadvantages. Inherently, it's still limited because there can never be perfectly accurate external data sources.

How many Chainlink (LINK) coins have been issued?

The decentralized network plans to issue 1 Billion LINK coins. In 2022 about 46.9% (469,099,970) of the total supply has been issued.

With the launch of Chainlink Economics 2.0, users can now participate in staking to help run the network. Stakers will earn rewards from several sources, including native token emissions and service fees. Eventually, most of the rewards are expected to be derived from the platform service fees as network adoption grows.
