Ethereum is the largest blockchain ecosystem to support decentralized applications using smart contract functionality. On the other hand, Chainlink is designed primarily as an infrastructure to provide these decentralized applications access to external data sources in a tamper-proof, blockchain agnostic, and secure manner. Here are some of the key differences between Chainlink and Ethereum: Ethereum Blockchain vs. Chainlink Platform Ethereum is a Layer 1 blockchain that hosts decentralized apps. It supports smart contracts and has ETH as its native digital asset or cryptocurrency. Chainlink is a platform that can support communication between different smart contracts and can supply real-world data to smart contracts in a format they can understand and use. Chainlink has limited functionalities in comparison with Ethereum. The Chainlink ecosystem is powered by LINK which serves as its native digital asset. ETH Coin vs. LINK Token Ethereum’s ETH or Ether is a cryptocurrency or a coin that is minted, as the blockchain leverages a proof of work consensus mechanism. As of May 2022, Ethereum has not yet migrated to the proof of stake consensus algorithm. Meanwhile, LINK is an ERC-20 token designed on the Ethereum blockchain. Forming a part of a PoS network, the LINK crypto cannot be mined but has to be staked or traded if you wish to obtain it. ETH vs. LINK Market Cap Difference Ethereum is the world’s second-largest cryptocurrency by market cap and enjoys extremely high trading volume, liquidity, and demand among investors worldwide. Chainlink has a far smaller market cap, although it is among the top 30 cryptocurrencies in terms of size and popularity.
