If you are an avid fan of anything but cryptocurrency and blockchain, then you must have come across the blockchain project known as Chainlink. Chainlink’s existence dates back to 2014 when a non-profit organization popularly known as SmartContract Ltd was founded. SmartContract Ltd quietly worked on the project until 2017 where it conducted an ICO for the project and managed to raise a staggering $32 million. Soon after, Chainlink began operations on the Ethereum blockchain, successfully netting itself some significant partnerships in the process.

Today, Chainlink is one of the most popular cryptocurrencies in the market ranking at position 17 on CoinMarketCap. Over the past four years, Chainlink has seen rapid and significant expansion amid the recent explosion in DeFi (Decentralized Finance). In this article, we are going to highlight what Chainlink is, how it works, some uses cases, and where you can buy or exchange it at the best rates. Stick around to the end of the article for our opinion on whether Chainlink’s value will rise and by how much.

What is Chainlink?

Chainlink is a decentralized network of oracles that aims to provide real-world information to smart contracts on the blockchain. Blockchain technology has grown to encompass more than just P2P online money transactions. Thanks to the Ethereum network, blockchain can now be used to deploy smart contracts that allow people to enter into contracts that automatically execute if defined conditions are met. Although these contracts are secure and tamper-proof, there is often a big problem when they have to access external data to support their functioning.

The issue is that blockchains don’t have any inbuilt mechanisms capable of accessing external data. They rely on data feeds and APIs from third-party entities that may or may not be accurate. Chainlink was designed to solve this problem by incentivizing information providers to become the bridge between blockchain-based smart contracts and off-chain data sources. These data providers otherwise referred to as “Oracles” would then receive rewards in form of Chainlink tokens for providing accurate data.

How Does Chainlink Work?

Chainlink works in a series of three steps. These three distinct steps include:

1. Oracle selection

In this step, a Chainlink user sends out a service-level agreement (SLA) on the Chainlink network. This SLA specifies a set of desired data requirements. The Chainlink protocol then creates a corresponding smart contract, a Chainlink Service Level Agreement Contract to acquire the required off-chain data. Basically, it uses the information in the SLA to match and connect the user with an oracle or oracles that can provide the desired data.

2. Data Reporting

In this step, the oracles connect with the external sources to obtain the real-world data required in the SLA. The oracles process the data and send it back to the contract. An internal system starts validating the data whereby the most accurate data is input on the chain.

3. Results Aggregation

In this step, the results of the data collected by oracles are tallied and compared through an aggregation contract. The work of the aggregation contract is to collect the data from oracles and match the most accurate results with the smart contracts that need them. To do this, it tests the validity of each response and assigns each result a weighted score.

What Does Chainlink Do?

Once a Chainlink user deploys an SLA contract on the Chainlink network, in the background, Chainlink takes advantage of three kinds of smart contracts to facilitate the process. These smart contracts include:

The Chainlink Aggregating Contract

This contract works by collecting data from oracles and trying to match the most accurate results with the smart contracts that require them the most.

The Order-Matching Contract

This contract delivers the user’s SLA request to Chainlink nodes. It also receives their bids on the request and selects the right type and number of nodes to fulfil the request. Eventually, it matches the SLA with the best bidding oracle.

The Reputation Contract

This contract takes all the data from the selected oracle and validates it or reconciles it for an accurate result. To verify the oracle’s integrity, it first checks the oracle’s track record. It relies on data such as the number of completed requests, average response time, and amount of Chainlink staking the oracle had done.

Chainlink Use Cases/Partnerships

Chainlink has successfully partnered with over 30 companies all of which are in various sectors across the world. Thanks to its wide use case capability, Chainlink has attracted multiple financial institutions and companies that have invested in it. Below is a list of some Chainlink partners and how they utilize Chainlink:

Wanchain

This Singapore-based company partnered with Chainlink back in 2018. Wanchain uses Chainlink to access financial market data. The company’s goal is to enable blockchain interoperability and it is greatly benefitting from the secure and accurate off-chain data it acquires through Chainlink.

Google Cloud

The partnership between Google Cloud and Chainlink was announced in 2019. Google Cloud utilizes Chainlink for its BigQuery service.

SWIFT

SWIFT utilized Chainlink in a proof-of-concept demonstration project that pushed financial data from several banks and financial firms such as BNP Paribas, Fidelity, Barclays, and Santander.

OpenLaw

The partnership between OpenLaw and Chainlink took place in 2018. ConsenSys owns OpenLaw. It utilizes Chainlink to transfer records on-chain.

Crypto transaction fees may vary depending on the network (Ethereum transaction fees tend to spike during the congestion on the network), your chosen cryptocurrency, an instant exchange provider as well as its transaction processing speed and internal policy. These fees may be relatively low but it’s crucial to know they may be imposed in the first place.

If you want to exchange cryptocurrency with the lowest fees, beware of the offers with a grey-colored “Transaction fees are not included” label displayed under the exchange rate. To avoid having to pay an unexpected amount of fees during the exchange, opt for those that do not have that label. Read our articles to learn more about how to exchange cryptocurrency with the lowest fees and find out which assets have the lowest transaction fees.

What is average transaction time?

Transactions usually take from 5 to 30 minutes to be processed, especially if you choose currencies with speedy networks. However, there are several factors that may affect and slow down the exchange process, i.e. transaction volume, blockchain capacity, network updates, cryptocurrency itself and the capacity or chosen exchange platforms.

The processing may take longer due to the large transaction volume, congestion of the network, blockchain overload and market overload, technical issues or system failures, lack of liquidity or network maintenance.

The transaction may be also stuck if you forget to add a required Extra ID, mistake networks or use the wrong wallet for a chosen crypto asset. If you worry that the exchange processing is taking too long, please, contact us at [email protected] or via our live chat on the landing page.
