Chainlink, launched in 2017 by Sergey Nazarov and Steve Ellis, aims to establish a reliable connection between blockchain applications and real-world data, revolutionizing the potential of smart contracts. While blockchain technology enables secure and transparent execution of these contracts, accessing data outside the blockchain poses a challenge. Chainlink solves this problem by acting as a decentralized oracle network. Furthermore, Chainlink allows smart contracts to connect securely to external data sources, payment systems, and APIs.

With an extensive presence in sectors like decentralized finance (DeFi), insurance, gaming, and more, Chainlink has safeguarded the security of tens of billions of dollars. Moreover, it provides global enterprises and prominent data providers with a universal gateway to interact with all blockchains seamlessly.

Chainlink is the industry standard for building, accessing, and selling oracle services needed to power hybrid smart contracts on any blockchain. Chainlink oracle networks provide smart contracts with a way to reliably connect to any external API and leverage secure off-chain computations for enabling feature-rich applications. Chainlink already secures tens of billions of dollars across DeFi, insurance, gaming, and other major industries, and offers global enterprises and leading data providers a universal gateway to all blockchains​.

$LINK is the native token of the Chainlink network. It is used to pay for the operation of various oracle services on the Chainlink network, as well as to incentivize the correct performance of these services and provide user assurances through staking. $LINK plays a crucial role in Chainlink's economic model by facilitating secure and reliable interactions within the ecosystem​.

The Chainlink network is secured by the proof-of-stake (PoS) consensus mechanism. Using PoS, the network uses the preferred consensus method since proof-of-work (PoW) consumes a lot more power. Although PoW is extremely reliable, blockchain networks such as Ethereum, Polygon, BNB Chain, etc., are setting a “new standard” by using PoS instead of PoW.

The LINK token is used to transact and purchase services on the Chainlink network. Also, it plays a crucial role in the network’s operations and serves three primary functions within Chainlink’s ecosystem:

1. Incentivizing Node Operators: LINK tokens are used as incentives to motivate node operators to perform tasks accurately and reliably. Node operators stake LINK as collateral, which acts as a form of security to ensure honest data reporting. The better the performance and reputation of a node operator, the more opportunities they have to earn LINK tokens.

2. Paying for Oracle Services: Users of the Chainlink network must pay LINK tokens to access the data provided by oracle nodes. This ensures node operators are compensated for their services and enables the sustainable operation of the oracle network.

3. Governance and Future Development: Holders of LINK tokens have the power to participate in the governance of the Chainlink network. They can propose and vote on protocol upgrades, improvements, and parameter changes, shaping the future direction of the ecosystem.

The LINK token operates on the Ethereum blockchain, adhering to the ERC-20 standard. Initially, Chainlink conducted an initial coin offering (ICO) in 2017, distributing the majority of LINK tokens to investors and supporters. As of the knowledge cutoff in September 2021, the total supply of LINK tokens stood at one billion, with a circulating supply determined by market demand and liquidity.

As the supply of LINK tokens can fluctuate based on demand and liquidity, we recommend checking the most recent data from reliable sources or consult a crypto exchange to obtain the current, most up-to-date information regarding the supply of Chainlink (LINK) coins.

$LINK supports several technological innovations, including:
- Hybrid Smart Contracts: Combining on-chain and off-chain components to enhance smart contract capabilities.
- Decentralized Oracle Networks (DONs): Enabling efficient, secure, and scalable oracle services.
- Off-Chain Reporting (OCR): Improving data aggregation and transmission to smart contracts.
-Confidentiality and Privacy: Technologies like DECO and Town Crier for secure and private data delivery​.

$LINK distinguishes itself from other cryptocurrencies through its robust oracle network that connects smart contracts with real-world data, its highly secure and decentralized node operator network, and its broad adoption across various industries. The Chainlink network's ability to provide reliable and tamper-proof data feeds makes it a critical infrastructure for decentralized applications (dapps) and smart contracts​​.

The team behind Chainlink and $LINK includes a global group of industry experts and advisors from top academic institutions and organizations. Key figures include Sergey Nazarov, Steve Ellis, and Ari Juels, among others, who bring extensive experience in blockchain technology, cryptography, and decentralized systems​​.
