Key Takeaways
- Chainlink (LINK) is a cryptocurrency project focused on creating a decentralized oracle network.
- Blockchains struggle to access data outside their networks, limiting smart contract functionality. Thus, Chainlink creates a network of oracles to provide blockchains with secure and reliable real-world data.
- LINK is a native token that fuels the Chainlink network and is used for payments and network security.
Chainlink (LINK) is a decentralized oracle network that allows smart contracts to access data outside of the blockchain. This way, Chainlink improves the functionality of dApps. It also serves as a critical interface between blockchain technology and the real world, significantly improving the efficiency of automated DeFi transactions.
This article will also help you understand and gain more knowledge about Chainlink, its history, and how it operates in the constantly changing landscape of digital currencies.
What Is Chainlink (LINK)?
Chainlink (LINK) is a cryptocurrency project that aims to bridge the gap between blockchains and the real world by providing a decentralized oracle network. An oracle is simply a computer (a node) that gathers data from different sources and then sends it to a smart contract that needs this data on the blockchain.
The project aims to enable smart contracts to interact with real-world data and events. This unlocks a wider range of applications for blockchain technology, such as DeFi, supply chain management, and the Internet of Things (IoT).
History
In 2017, Sergey Nazarov and Steve Ellis established Chainlink to solve the issue of linking smart contracts to real-world applications in a safe, trustless manner. In the first stages of the project, the team aimed to build a decentralized oracle network that would function on a proof-of-stake basis.
The LINK token associated with Chainlink was created in 2017 via an initial coin offering (ICO), while the actual network was running by 2019. Afterward, Chainlink advanced rapidly, evolving into the dominant oracle network in the blockchain ecosystem and enabling cloud applications in multiple sectors. The platform’s success has been ascribed to its high level of security, scalability, and multiple data integrations.
How Does Chainlink (LINK) Work?
Chainlink acts as a decentralized oracle network middleman between smart contracts and the real world. Here’s a simplified breakdown:
Requesting Data
Smart contracts, which are self-executing programs on a blockchain, can’t directly access external data. Instead, they initiate a request through the Chainlink network to interact with real-world information. This request specifies the type of data needed and the desired security level.
Oracle Selection
Chainlink does not rely on a single data source. Instead, it utilizes a decentralized network of oracles. These oracles are independent entities responsible for retrieving data from external sources like APIs or web servers:
- Service Level Agreements (SLAs) – The requesting contract can specify requirements in an SLA. This SLA might outline the data source, desired accuracy, and even collateral put down by oracles to ensure good behavior.
- Chainlink’s Reputation System – Chainlink maintains a reputation system that evaluates oracles’ past performance. This helps select reliable oracles for each data request.
Data Fetching
Based on the request and reputation scores, Chainlink selects a set of oracles to retrieve the data. Each oracle independently fetches the data from the designated source.
Data Aggregation And Security
The retrieved data from different oracles is sent back to Chainlink. Chainlink’s smart contracts, called aggregation contracts, play a crucial role here:
- Data Aggregation – They combine the data from various oracles, often using techniques like median or averaging to eliminate outliers and improve accuracy.
- Tamper Detection – The aggregation contracts can also identify inconsistencies between the data points. This helps detect and discard potentially manipulated data.
Delivering Data To Smart Contracts
Once the data is aggregated and secured, the final, reliable data point is delivered back to the smart contract requesting it on the blockchain. Based on the received data, the smart contract can then proceed with its programmed actions.
Payment With LINK Tokens
LINK tokens are used to pay oracles for their data retrieval services. The requesting smart contract pays in LINK, and the network distributes the fees among the participating oracles.
This process ensures that smart contracts can securely access and leverage real-world data for their operations, enabling a more comprehensive range of functionalities within the blockchain ecosystem.
Chainlink (LINK) Token And Tokenomics
Tokenomics
The LINK token is at the heart of Chainlink’s ecosystem, serving a variety of tasks across the network. First and foremost, LINK is an incentive for node operators that provide reliable information to smart contracts; in exchange, they receive LINK tokens. In addition, LINK is utilized to pay for data feeds and services offered by Chainlink.
Regarding token supply, the total LINK circulation is limited to 1 billion, with a portion saved for the development team, early investors, and community reserves. LINK’s overall demand and utility within the Chainlink ecosystem, combined with the growing need for decentralized Oracle solutions in the blockchain industry, drives LINK’s value. There are safeguards in place to allow for the destruction of tokens, ensuring that the token remains valuable in the long run and is in limited supply.
