In the fast-paced realm of blockchain technology, various revolutionary concepts have emerged, reshaping the way we perceive and interact with digital assets. Among these groundbreaking developments, the concept of decentralized oracles has gained significant attention, with Chainlink standing at the forefront of this innovative landscape.
Blockchain technology alone has limitations when it comes to accessing and utilizing real-world data securely and reliably. This is where Chainlink comes into play, bridging the gap between smart contracts and external data sources through its decentralized oracle network. In this article, we will explore the history of Chainlink, from its conceptualization to its realization, and delve into the unique capabilities it brings to the world of blockchain technology.
In this article, we will explain the fundamental concept of Chainlink Oracle and how it can boost power of blockchain technology. Also, we will discuss the difference between Chainlink’s native token LINK and Bitcoin in context of investment.
So, let’s begin.
What is Chainlink Oracle?
Chainlink, launched in 2017, is a decentralized oracle network built on blockchain technology. Oracles serve as intermediaries between blockchains and external systems, enabling smart contracts to execute using data inputs and outputs from the blockchain. Unlike traditional oracles that are centralized, Chainlink introduces a decentralized approach through “hybrid smart contracts.” This approach facilitates the secure and efficient transfer of data to and from blockchains.
In the Chainlink network, LINK tokens play a crucial role. They are used to incentivize network operators who retrieve data from off-chain sources, format it into accessible formats, and perform off-chain computations. These operators are part of a system of nodes that operate according to predefined protocols. To participate as node operators, individuals must stake or lock a specific number of their LINK tokens. Node operators have the flexibility to set their own fees based on the demand for the off-chain resources they provide.
Features of Chainlink Oracle
Chainlink is a cutting-edge blockchain technology that revolutionizes the way data is securely shared, computations are performed, and outputs are generated. With its advanced features and robust infrastructure, Chainlink is paving the way for the seamless integration of blockchain and real-world data. Let’s explore some of the key features that make Chainlink stand out in the world of oracles:
1. Supporting Decentralized Data Feeds
Chainlink excels in securely collecting and processing data from multiple sources. Its decentralized data feeds enable hybrid smart contracts to access real-time, accurate, and reliable information from various providers. This ensures the trustworthiness and tamper-proof nature of smart contract inputs, enhancing the security and integrity of the blockchain ecosystem.
2. Providing Verifiable Sources of Randomness
Chainlink’s verifiable sources of randomness are invaluable for applications like gaming platforms.

Limitations of Smart Contracts and How Chainlink Solves Them
Current smart contract model holds some limitations.
1. Data Connectivity
Smart contracts, by design, operate within the blockchain ecosystem and lack direct connectivity to external data sources. This restricts their ability to retrieve real-time information required for decision-making and automated execution.
2. Data Reliability
Verifying the accuracy and reliability of external data is crucial for smart contract functionality. Without a trusted and decentralized solution, smart contracts may be exposed to data manipulation or inaccuracies, potentially leading to undesired outcomes.
3. Interoperability
Smart contracts deployed on different blockchain networks face challenges in accessing and interpreting data across multiple systems. Achieving seamless interoperability is essential to enable the broader adoption and scalability of smart contracts.
Chainlink solves these limitations by providing a decentralized oracle network that acts as a bridge between smart contracts and external data sources. Chainlink oracles securely retrieve and verify real-world data, ensuring its integrity before feeding it into smart contracts. By doing so, Chainlink enables smart contracts to interact with real-world information, expanding their capabilities and use cases.

Comparison between Chainlink’s LINK and Bitcoin
1. Purpose and Functionality
Bitcoin serves as a digital alternative to money and focuses on recording and transferring ownership of the cryptocurrency through a decentralized network and blockchain technology. On the other hand, Chainlink utilizes blockchain technology to facilitate smart contracts, which are automated contracts executed directly between individuals without the need for intermediaries. Chainlink addresses the challenge of accessing external information required to complete smart contracts by incentivizing information providers (oracles) through a reputation system and rewarding them with LINK tokens.
2. Transaction Type
Bitcoin transactions involve the transfer of ownership of the cryptocurrency, which is recorded on the public and permanent blockchain ledger. In contrast, Chainlink’s transactions revolve around the execution of smart contracts, where the fulfillment of conditions within the contract triggers specific actions.
3. Token Usage
Bitcoin’s native cryptocurrency is Bitcoin itself (BTC), used as a medium of exchange and store of value. In contrast, Chainlink has its own cryptocurrency called LINK, which is used to incentivize and compensate information providers (oracles) for their services in facilitating accurate data for smart contracts.
4. Limited Supply
Both Bitcoin and LINK have a limited supply. Bitcoin has a maximum supply of 21 million coins, and once this limit is reached, no more BTC will be minted. Similarly, Chainlink has a maximum supply of one billion LINK tokens, after which no additional tokens will be created.
Which is better investment option between BTC and LINK?
The question of whether Chainlink or Bitcoin is the better investment is a difficult one to answer. Both have their advantages and disadvantages, and it ultimately depends on your investment goals and risk tolerance.
If you are looking for a long-term investment and are willing to take on more risk, Bitcoin may be the better choice. It has proven to be a good store of value, and its price has been steadily increasing over the years. However, it is also highly volatile, and its price can fluctuate dramatically in a short period.
