Why Chainlink's decentralised oracle network sets it apart from other blockchain solutions.
Blockchain technology has revolutionised the way we transact and exchange value.
However, one of the biggest challenges facing blockchain applications is obtaining reliable, accurate data from the real world.
This is where blockchain oracles come in. Oracles are essential tools that provide smart contracts with external data, enabling them to interact with the outside world.
By offering a secure, decentralised and versatile solution for obtaining real-world data, Chainlink (LINK) has emerged as the clear best blockchain oracle provider.
In this blog post, I’ll explore why Chainlink is considered the best, as well as looking at why it's becoming an increasingly popular choice among developers and businesses alike.
What does oracle mean in blockchain?
In the context of blockchain technology, an oracle is a third-party service that provides smart contracts with external data.
Smart contracts, being self-executing programs that run on a blockchain, are designed to automate the execution of contracts without the need for intermediaries.
However, smart contracts are limited in their ability to interact with the outside world.
They struggle to access and interact with real-world data, which is necessary for many applications.
This is where oracles come in.
Oracles act as intermediaries between the blockchain and the outside world, providing smart contracts with access to real-world data.
Data on things like stock prices from a private exchange, footy results or even the weather.
Oracles can also trigger events on the blockchain based on external data.
Events like automatically executing a contract when a specific condition is met in the real world.
The reliability and accuracy of the data provided by oracles are critical for the proper functioning of blockchain applications.
Inaccurate or manipulated data can compromise the security and integrity of smart contracts.
Ultimately leading to financial loss or other negative consequences.
Chainlink is designed to address these challenges.
Its decentralised network of node operators ensures that data is sourced from multiple independent sources, reducing the risk of manipulation or tampering.
Chainlink's data is also secured through a cryptographic proof system, which guarantees the accuracy and integrity of the data.
With that in mind, let’s now take a look at how they actually work.
How do Chainlink oracles work?
Chainlink oracles are a decentralised network of node operators that provide external data to smart contracts on the blockchain.
Here's a simplified explanation of how they work:
- Requesting data: A smart contract on the blockchain requests external data from Chainlink.
- Node operators: Chainlink uses a decentralised network of node operators, each responsible for providing data on specific data feeds.
- Aggregation: Chainlink aggregates the data from multiple node operators to ensure accuracy and prevent manipulation. The aggregated data is then passed on to the smart contract.
- Verifiable randomness: Chainlink uses a verifiable randomness system to select the node operators that provide data for each data request. This ensures that the selection process is fair and transparent.
- Payment: Chainlink uses its native token, LINK, to pay node operators for their services. This incentivizes node operators to provide high-quality data and maintain the integrity of the system.

Put simply, by leveraging a decentralised network of node operators, Chainlink is able to ensure the reliability and accuracy of external data provided to smart contracts.
From decentralised finance to supply chain management, this makes Chainlink a valuable tool for a wide range of blockchain applications.
Does Chainlink solve the oracle problem?
To wrap up, Chainlink does solve the oracle problem.
There’s no doubt that Chainlink is widely regarded as the best blockchain oracle solution available today.
By leveraging a decentralised network of node operators, Chainlink provides secure, reliable and accurate external data to smart contracts on the blockchain.
Chainlink's versatility and wide range of data types make it a valuable tool for many different applications.
While no technology can completely solve the oracle problem, Chainlink has made significant progress in addressing the challenges of obtaining external data in a reliable and secure manner.
Its decentralised approach to data sourcing and verification, along with its verifiable randomness system, ensure the accuracy and integrity of the data provided to smart contracts.
As blockchain technology continues to evolve and expand into new use cases, the importance of reliable external data will only continue to grow.
Chainlink's decentralised oracle network is well-positioned to meet this demand and provide a crucial infrastructure for the next generation of blockchain applications.
