What Is Chainlink and How LINK works?

What Is Chainlink?

Chainlink is an oracular network that is decentralized and permits smart contracts to bring in data, APIs, and banking systems to smart contracts securely. Its primary function is to enable blockchain applications to be more utilized through access to correct off-chain data in a trustless, tamper-resistant way. While every blockchain is decentralized, Chainlink bridges the disconnect between off-chain data sources and on-chain smart contracts to allow blockchain programs to act upon outside occurrences, market rates, and other off-chain data in real time.

How Chainlink Operates

Chainlink operates based on the principle of a decentralized or distributed network of oracles aggregating and validating external information before it sends the data to blockchain smart contracts. Here is how it works:

• Data Request. A smart contract of the blockchain off-chain requests certain off-chain data.

• Oracle Selection. Chainlink's network selects a range of oracles to retrieve data as needed.

• Data Aggregation. Oracles fetch data from various sources and return to Chainlink's network.

• Validation & Computation. Chainlink aggregates the data from the numerous oracles to remove inconsistencies and make it precise.

• Delivery to Smart Contract. The validated data is then delivered to the smart contract and it runs on the received data.

Such multi-validation ensures security, reliability, and transparency without any point of failure or interference.

What Blockchain Is Chainlink On?

If we want to find out what is Chainlink crypto, we firstly need to clarify that Chainlink started on Ethereum and is still a core part of the Ethereum network. Chainlink oracle services are, though, blockchain-agnostic, and Chainlink is able to function on multiple other blockchains, including:

• What is Ethereum Chainlink? The initial and primary network Chainlink serves.

• What is Polkadot Chainlink? Chainlink provides oracles for Polkadot-based projects to enable interoperability.

• Binance Smart Chain (BSC). Bringing DeFi apps on BSC with correct price feeds.

• Solana (SOL). Relies on Chainlink to securely process on-chain information.

• Polygon (MATIC). Uses Chainlink for cheap, quick transactions with real-world input data.

• What is Litecoin Chainlink. Chainlink provides security and smart contract capability to Litecoin's network.

Chainlink's cross-blockchain functionality makes it the go-to option for DeFi, insurance, gaming, supply chain management, and more.

What Is Chainlink Used For?

Chainlink is used at scale across a wide range of industries such as:

• Decentralized Finance (DeFi) -- Used in lending, derivatives, and stablecoins for safe price feeds (e.g., Aave, Synthetix).

• Gaming & NFTs -- Used to offer honest randomness and safe data feeds for blockchain gaming and NFT use cases.

• Insurance -- Provides real-world weather, flight, and supply chain data to facilitate automated claims in insurance.

• Enterprise Solutions -- Binds to existing banking and finance infrastructure for secure data verification.

What Is Chainlink Price?

Chainlink uses its native token, LINK, to remunerate node operators for retrieving, validating, and relaying off-chain data. The market demand, network growth, and overall usage of the Chainlink network determine the value of LINK.

Conclusion

Chainlink is a foundational building block of infrastructure for blockchain technology that enables smart contracts to receive external real-world data in a secure, decentralized way. Chainlink is a critical driver of DeFi growth, enterprise adoption, and beyond by providing secure, trusted tamper-proof oracles across a variety of blockchains.
