September 2017: Project launch

On September 20th, 2017, the Chainlink ICO was closed after raising more than 32 million dollars. Following this, the LINK token was launched on its first platform. In the two weeks that followed its launch, this token went through a 300% price increase.

December 2017: Parabolic increase

After going through a correction of approximately 70% in only a month, the price of LINK went up to $0.71, which corresponds to a 330% increase. This rise continued during the following weeks, going up to $1.42 before entering an 80% correction period.

After reaching its lowest price of $0.16 in June 2018 (during a bear market period), the token finally rebounded and its price went back up. In early 2019, LINK went through a strong price increase that will last until June 2019, propelling its price to $4.53. In only 6 months, the token’s value had a 1,400% increase, its price was multiplied by 16.

The whitepaper for Chainlink 2.0 was published on its website in April 2021, detailing the future changes and features of the project.

Chainlink is a decentralized network that allows for the digitization of information that is found in sources outside of the Blockchain (off-chain), in order to then integrate it to Smart Contracts through an oracle network.

The problem with Smart Contracts is that they can only deal with data that is present inside a Blockchain (on-chain). Although they play a crucial role in a network, this limits their potential greatly, notably in their ability to interact with external data such as:

  • Meteorological data
  • Sport results
  • Fiduciary currencies

This is where an oracle comes into play. However, by using a single centralized oracle, the data that is gathered from the physical world can be faulty (hacking, error…) and therefore misleading to the Blockchain on which it will be imported.

It’s at this point that Chainlink shows its usefulness, thanks to its decentralized network of oracles; these act as “gateways” that allow for the safe addition of data from the real world (off-chain) to a Blockchain network via Smart Contracts. This solution eliminates security and reliability issues that could potentially be met with a single, centralized source (oracle).


Chainlink’s main objective is to create a digital gateway that connects data from the Blockchain (on-chain) to the external world (off-chain). Chainlink is therefore made of two types of infrastructure, on-chain and off-chain.

Here’s a detailed explanation of the way Chainlink and its ecosystem work.

On-chain infrastructure

First of all, “oracle contracts” treat the data requests made by users. The nodes of the Chainlink blockchain then examine the requests made by users who wish to get off-chain information, using USER-SC contracts known as “user contracts”.

After this, the contract oracle of Chainlink generates three different types of sub-contracts:

  • Reputation contract: its role is to examine the background of an oracle provider, to check among other things its authenticity and history, in order to guarantee its reliability before forwarding a request to an “order-matching contract”.
  • Order-matching contract: this contract transfers the contract from which the request originates (user contract) to the relevant oracle depending on the service requested and the offers available. It then collects and selects the best “offers” from oracle providers, based on the results provided by the reputation contract.
  • Aggregating contract: lastly, the aggregating contract collects all the feedback from oracle providers, analyzes this data, and then determines the final result of the Chainlink request. Note that if the results given by different oracles are not identical, adjustments are made at this stage.

To sum up, the process of on-chain functions is made of three steps:

  • Oracle selection (Reputation contract) 
  • Data declaration (order-matching contract) 
  • Aggregation of the results (aggregating contract)

Users can configure or replace Chainlink contracts as they wish thanks to their modular features.

Off-chain infrastructure

The “off-chain” part of Chainlink’s infrastructure deals with data that comes from outside the Blockchain. It is a network of what are called “oracle nodes” that are connected to the Ethereum network. Chainlink founders insist on the fact that they are striving to make their platform compatible with all major Smart Contracts networks available on the market.

Chainlink nodes first collect data from a source that is external to the Blockchain, in order to take care of the data request specified in the “user contract”. To translate this request, nodes use “Chainlink Core“, a central node software that links on-chain and off-chain data.

Chainlink Core translates the data request from an on-chain programming language to an off-chain language, so that data sources from the real world can understand this request.

“Chainlink’s node software comes with integrated subtasks, including HTTP requests, JSON analysis and conversion to various blockchain formats.”

Once the request is translated by Chainlink Core, an external API (Application Programming Interface) collects data from the source.

After this, the data is once again translated to an on-chain programming language in order to be interpreted by the Blockchain. The data is then forwarded to Chainlink’s aggregation contract that will validate data from several sources at once.

Node developers can also add programs known as “external adapters”, which offer additional off-chain services to users. Adapters can notably be used to simplify the use of programs that work with a complex, multi-step API.

LINK was built on the Ethereum Blockchain in compliance with the ERC-20 norm for tokens. This token has an additional ERC223 feature known as “transfer and call”, which enables tokens to be treated by contracts in a single transaction. It can be bought or sold using fiduciary currencies or other digital currencies.

The LINK token has a primordial role in the Chainlink ecosystem and the functions of the network. Here are the cases in which Chainlink (LINK) is used:

  • Node operators

The LINK token is used to pay the Chainlink node operators as a reward for their work (notably the retrieval of data from off-chain sources). Prices are fixed in advance by operators, depending on the demand for off-chain data.

Node operators also use LINK to participate in the Chainlink network and ecosystem. They have to deposit LINK to contribute to the network and prove their engagement in it.

LINK is also used for the following purposes:

  • Paying for data conversion to formats that can be read by the Blockchain
  • Paying for off-chain operations
  • Being used as a warranty for node operators

Although it is very useful in the Chainlink network, the LINK token does not really provide any advantages for most of its owners, contrary to other cryptocurrencies such as BNB.

However, if the project reaches its ambitious objectives, this could revolutionize the use and efficiency of smart contracts, which would likely cause the price of the LINK token to increase.
