Chainlink is a decentralized oracle network that allows public blockchains and smart contract platforms to bring external, off-chain data sources to on-chain operations. It seeks to address the oracle problem — the ongoing challenge of linking off-chain data with on-chain data with minimal trust in third parties. In a nutshell, Chainlink provides a valuable service by making real-world data such as market stats, event outcomes, and even the weather available on the blockchain without relying wholly on centralized data providers.

LINK, Chainlink’s native token, is used to pay the network’s node operators, or oracles, for providing secure data feeds. 

Read on for our deep dive into the Chainlink project, the Chainlink (LINK) tokens, and learn how to buy Chainlink and why real-world data is valuable on the blockchain.

Let’s dive in!

Before discussing how to buy LINK, let’s first look into Chainlink, a decentralized oracle network designed to supply smart contracts with credible, real-world data. These oracles let Chainlink smart contracts get solid real-world, off-blockchain data from external sources, such as any kind of API and some other types of external data feeds. In other words, Chainlink takes the capabilities of smart contracts to the next level by enabling access to real-world data, such as currency exchange rates, weather data, events, payments, etc., without sacrificing the security and reliability that are inherent to blockchain technology. It allows storing, calculating, or otherwise utilizing data from the rest of the world through a reliable and decentralized source of information.

A decentralized oracle solution, such as the Chainlink network, makes blockchain accessible to the rest of the world in several ways:

  • Weather data will be used to determine insurance rates
  • Supply chain tracking will benefit from location data
  • Sporting events will be used to settle decentralized sports betting
  • Political events will be used to settle prediction markets.


LINK is the Chainlink network’s native token used to pay for services. The smart contracts that request the data pay Chainlink node operators in LINK for their service. Node operators also stake LINK to ensure long-term commitment to the project and are incentivized with LINK rewards to encourage acting trustworthy rather than being malicious.

LINK is based on Ethereum and is in line with the ERC20 token standard. Though originating on Ethereum, Chainlink is interoperable and designed to work across any blockchain with smart contract functionality.

LINK tokens can be purchased on cryptocurrency exchanges and traded in exchange for fiat or other digital currencies. They may be saved in a cryptocurrency wallet and custodian, such as the CoinStats wallet, Gemini, etc.

Crypto-Economic Safety: Chainlink enables leveraging contractual service agreements that outline the parameters of an Oracle service and include monetary penalties for bad performance.

End-to-End Decentralization: Chainlink employs decentralized oracle networks comprised of independent and Sybil-resistant nodes to avoid data tampering. It also contributes to the cryptocurrency’s high availability.

Blockchain Agnostic: Chainlink is a single framework that links all major public and private blockchain ecosystems, and it also acts as a common abstraction layer for cross-network connections.

Nodes With High Security: Every piece of data in Chainlink is digitally signed by nodes and saved on-chain. It also gives cryptographic evidence of the overall security of Oracle networks.

In-depth Defense: Cryptographic signatures, trusted execution environments, zero-knowledge proofs, and other security measures can be used.

Data of High Quality: On Chainlink, you may access any password-protected or secured API data source. This procedure can prevent several nodes from performing duplicate validation for any single point of failure.

Open-Source Community: There is a vibrant chainlink open community. Developers, node operators, security auditors, and researchers are all part of this community. Members of this community contribute often, which helps to improve network security while also speeding up development.

Chainlink follows an innovative three-step process to allow communication between its users and external data sources:

Oracle Selection: To begin, Chainlink users create a service-level agreement (SLA) outlining a set of desired data needs. The program then uses the SLA to match users with oracles that can provide the data. After setting the parameters, users submit the SLA and deposit their LINK cryptocurrency into an Order-Matching contract that takes bids from oracles.

Data Reporting: This is where the oracles connect with the external sources to receive the real-world data specified in the SLA. The data is subsequently processed by the oracles and returned to the Chainlink blockchain contracts.

Result Aggregation: The last stage is summing up the results of the data collected by the oracles and returning them to the Aggregation contract. The Aggregation contract collects the replies, evaluates their validity, and gives users a weighted score based on the total of all the data received.

The easiest method to buy and sell LINK Chainlink is through a cryptocurrency broker. You may exchange your fiat currencies or any other digital currency into Chainlink with a few clicks.

You must choose a broker who will enable you to conveniently and safely trade Chainlink.

Almost all crypto exchanges allow you to buy LINK. To select the one that suits you best, you must consider specific characteristics such as:

  • A broker’s platform that’s dependable and simple to use. If you are a newbie, you might consider using a more user-friendly broker, such as Coinbase. However, if you are a more experienced trader/investor, you may want additional charts to make your next move. In such a case, Coinbase Pro is a viable option.
  • A wide range of cryptocurrencies available for purchase on the platform.
  • The assets provided by the broker. While some brokers exclusively sell cryptocurrencies, others offer both crypto and stock accounts.
  • The fee system. Both commissions and maintenance expenses are to be included.
  • Two-factor authentication, encryption, and security measures should be available.

After comparing the services and costs imposed by the crypto brokers allowing you to buy LINK, you should select the one that best meets your financial objectives.

You can choose between a cold wallet (hardware wallets) and a hot wallet (mobile and desktop wallets).

Hardware wallets are preferable if you intend on keeping Chainlink for an extended period, as they give the maximum level of protection. These are secure offline storage alternatives, and your keys are stored on a physical device. Hardware wallets may be purchased almost everywhere, including online retailers such as Amazon. These wallets function similar to a flash drive, allowing you to connect to a PC or laptop to transfer money into a secure wallet.

Chainlink (LINK) is one of the most renowned cryptocurrencies with enormous growth potential. It’s not only backed by the correct technology but also has sufficient resources for future development. The best aspect is that Chainlink has a fantastic community. So far, the initiative has won a slew of accolades, including recognition as a World Economic Forum Technology Pioneer in 2020.

Chainlink dramatically expands the capacity and use cases of smart contracts by allowing blockchain to access real-world data, payments, events, etc., efficiently. Approximately 20,000 individuals now serve as Chainlink node operators, contributing to the project’s goal of establishing an utterly decentralized oracle network.

With the emergence of staking, yield farming, etc., users are searching for new ways of investing crypto assets for more than simply capital gains. Staking LINK involves running a Chainlink node or joining a Chainlink stake pool to connect blockchains with off-chain data and receive payments in LINK for exchange.

If blockchain oracles gain traction, and LINK is at the forefront of that, earning LINK for providing off-chain data to smart contracts would pay off handsomely for stakeholders.


Chainlink solved the oracle problem on how to retrieve and share information from oracles without putting the security of the blockchain at risk. It created a decentralized network, where instead of having to trust a source, smart contracts run through the Chainlink network and have access to resources like data feeds, traditional bank account payments, and web APIs.
