Founded in 2017 by Sergey Nazarov and Steve Ellis, Chainlink is an open-source, decentralized Oracle network that connects smart contracts with external data sources, APIs, and payment systems.
The Chainlink network is powered by the LINK token. LINK is an ERC-20 token that is used to pay oracles for their services.
Unlike traditional smart contracts, which rely on external data feeds that can be manipulated, Chainlink’s Oracle network ensures secure and reliable data delivery to smart contracts. This empowers developers to create powerful and versatile blockchain applications that leverage real-world data.
Smart contracts are self-executing agreements built on blockchains like Ethereum. They can automate various tasks and transactions based on predefined conditions.
However, a major limitation of smart contracts is their inability to access external data sources independently. This is where oracles come into play.
Oracles act as bridges between blockchains and the outside world. They fetch data from external sources (APIs, web servers, etc.) and deliver it securely to smart contracts. The data retrieved by oracles can be anything from stock prices and weather forecasts to flight information and payment confirmations.
The security and reliability of oracles are paramount for the proper functioning of smart contracts. If an oracle provides inaccurate or manipulated data, it can lead to significant financial losses and disrupt the entire application.
Decentralized Node Operators: Chainlink’s network relies on a decentralized ecosystem of node operators, ensuring data integrity, redundancy, and censorship resistance.
External Adapters: Chainlink allows developers to create custom external adapters, expanding the platform’s capabilities and enabling integration with virtually any external system or API.
Reputation System: Chainlink implements a reputation system to incentivize node operators to provide accurate data and penalize malicious behavior, fostering trust within the network.
Cross-Chain Compatibility: Chainlink is designed to be blockchain agnostic, seamlessly integrating with various blockchain platforms.
On-Chain Governance: Chainlink’s community-driven governance model empowers token holders to participate in decision-making processes, ensuring the platform evolves in a decentralized and inclusive manner.
By eliminating a single point of failure, Chainlink mitigates the risk of data manipulation or tampering.
The use of multiple oracles and data aggregation makes it extremely difficult for malicious actors to alter the delivered data.
The entire process of data retrieval and aggregation is transparent and verifiable on the blockchain.
Chainlink's network is permissionless and decentralized, meaning anyone can participate as an oracle node.
The network can support a wide variety of data types and sources, catering to diverse smart contract applications.
A smart contract initiates a request for specific data from the Chainlink network. This request includes details like the data source, the desired format, and the fee the contract is willing to pay for the data retrieval.
The Chainlink network uses a reputation-based system to select oracles to fulfill the request. Factors like a node's past performance, security deposit, and computational resources are considered during selection.
The chosen oracles securely retrieve the data from the designated external source. This process happens off-chain, meaning it occurs outside the blockchain environment.
Once retrieved, the data from multiple oracles is aggregated. This helps to eliminate outliers and ensure data accuracy. Chainlink uses various aggregation methods depending on the type of data and desired level of security.
The aggregated data is then submitted back on-chain and delivered to the requesting smart contract. The smart contract can then process the data and execute its programmed actions accordingly.
Chainlink’s decentralized oracle network has opened doors for innovative blockchain applications across various industries. Here are a few examples:
Chainlink oracles enable secure and reliable price feeds for DeFi protocols, allowing for automated lending, borrowing, and margin trading.
Real-time tracking of goods and materials throughout the supply chain can be achieved using Chainlink oracles, promoting transparency and efficiency.
Automated claims processing and risk assessment can be facilitated by integrating Chainlink oracles with insurance smart contracts.
Secure data exchange between connected devices and smart contracts is made possible through Chainlink's Oracle network.
Chainlink can provide verifiable randomness for blockchain games and other applications that require unpredictable outcomes.
LINK is an ERC-677 token built on top of the Ethereum blockchain. This standard inherits functionalities from the widely used ERC-20 token standard, ensuring compatibility with Ethereum wallets and exchanges. Currently, LINK ranks among the top 15 cryptocurrencies and is available for trading on most major cryptocurrency exchanges.
When a smart contract requests data from the network, oracles compete to fulfill the request.
LINK tokens are used to pay the chosen oracles for their service. This payment system ensures oracles are adequately compensated for their work and resources.
To participate in the network and become eligible for providing data, node operators must stake a certain amount of LINK tokens. This staked LINK acts as collateral.
If an oracle consistently delivers inaccurate data, its stake is slashed, discouraging bad actors and promoting data integrity.
While Chainlink is not fully governed by a token, LINK holders may have future voting rights on network upgrades and protocol changes. This is still under development, but it highlights the potential for community involvement.
As more smart contracts rely on Chainlink for secure data feeds, the demand for LINK tokens to pay oracles increases, potentially driving up the price.
There's a total supply of 1 billion LINK tokens, with a circulating supply of around 590 million. This scarcity could influence the token's value based on market forces.
Node operators can earn LINK tokens for providing reliable data. This incentivizes participation and network security, potentially increasing LINK's value over time.
