Ethereum and Polygon are significant players in the blockchain and cryptocurrency sectors. While Ethereum has pioneered smart contract platforms, Polygon has emerged as a promising Layer 2 scaling solution. This article delves deep into their characteristics, differences, similarities, and how they fit into the broader blockchain ecosystem. What Is Ethereum (ETH)? Ethereum, often called the “world computer,” is a decentralized platform that enables developers to build and deploy smart contracts and decentralized applications (DApps). Launched in 2015 by Vitalik Buterin and a team of other developers, Ethereum has been at the forefront of the blockchain revolution, introducing the concept of programmable transactions. Its native cryptocurrency, ETH, is used to power these applications and acts as a form of “gas” for transactions on the network. What Is Polygon (POL)? Polygon (POL) is a Layer 2 scaling solution for Ethereum. It aims to provide faster and cheaper transactions on the Ethereum mainchain by building a multi-chain system. With Polygon, developers can create sovereign blockchains with customizable environments while still leveraging the security and ecosystem of Ethereum. POL, the native token of Polygon, is used for transaction fees and staking within the network. How Layer 2 Works? Layer 2 solutions, like Polygon, are essentially blockchain protocols built on top of existing blockchains (in this case, Ethereum) to improve their scalability and efficiency. They handle transactions off the main chain, reducing congestion and lowering fees. Once the off-chain transactions are complete, they are batched together and added to the main chain. This approach allows for a significant increase in transaction throughput without compromising the security of the main chain. Ethereum vs. Polygon — Key Differences
