LINK vs. BTC and ETH

Both BTC and ETH are native cryptocurrencies on their own blockchain networks. This means both cryptocurrencies are utilized as economic incentives to keep their networks secure. LINK is different in that it is not a native cryptocurrency on its own blockchain network. Instead, LINK is a token built on top of the Ethereum blockchain. Without a network of its own, it relies on the Ethereum blockchain to enable security and transparency for transactions and smart contracts.

What is Chainlink?

To execute smart contracts, blockchain networks turn to oracles – data feeds that connect real world information to blockchain networks. But centralized oracles introduce new problems to decentralized networks. They rely on singular sources of data prone to attack from hackers and susceptible to relaying incorrect information back to the blockchain. 

Chainlink is a network of decentralized oracles that connect real world data with blockchain networks. This way, smart contracts can source off-chain data in a decentralized manner. Because Chainlink is deployed on the Ethereum blockchain, it can be utilized for any Ethereum-based decentralized application and can work across blockchain platforms as well. When someone requests off-chain data, they send a request to Chainlink, which then matches the request with the appropriate oracles to provide the relevant information, and aggregates the data to approach the most accurate result.

SLA

A service-level agreement (SLA) is drafted by the Chainlink user to specify what data needs to be retrieved. 

Oracle selection

Chainlink matches the SLA with the oracles capable of providing the solicited information.

LINK deposited

The user submits the SLA and deposits LINK as payment for the contract. 

Bids

Oracles bid for the contract.

Data collection 

After oracles are selected, they connect with external data sources to obtain the requested information and send it back to contracts on the blockchain.

Data aggregation

All data obtained by the oracles is collected and aggregated, with a weighted score given based on the validity of the data and the reputation of each oracle. The results are sent to the user.

For instance, say a smart contract was to trigger based on the exact temperature in New York City at a specified date. Instead of relying on a single source to impart the temperature data, Chainlink would utilize multiple oracles to aggregate the most accurate temperature data and relay this information back to the smart contract.

But what if oracles want to trick smart contracts by providing incorrect data? Luckily, Chainlink created its own token to generate proper economic incentives so that oracles would always act in the network’s best interest.

The LINK Token Has Exploded in Value 

LINK is an ERC-20 token built on the Ethereum blockchain. The LINK token is used to incentivize oracles to provide accurate data back to the platform for triggering smart contracts. Oracles that deliver accurate data are rewarded in LINK tokens for their work. 

There is a total of 1 billion LINK tokens that were originally minted with the following breakdown:

  • 30% held by the Chainlink development team
  • 35% sold via public sale
  • 32% allocated to node operators

After holding its initial coin offering (ICO) in 2017, LINK began trading on the open market. But the cryptocurrency didn’t get noticed until 2019 when it started to gain ground in the industry. By the end of 2019, LINK had gone from $100 million in value to $650 million, and a price of $1.80. 2020 was the breakout year for LINK, as it became a top-10 cryptocurrency, surpassing $6 billion in market capitalization and reaching a peak price above $18.

chainlink cryptocurrency market value growth

One reason LINK has the potential for even more growth is because of the decentralized finance (DeFi) industry. Oracles are an important piece of infrastructure in DeFi products as they impart real world pricing information necessary to update and execute DeFi smart contracts. DeFi contracts rely on accurate pricing feeds from off-chain markets to supply peer-to-peer financial products.
