Polygon vs aelf

Polygon, formerly Matic Network, is a blockchain platform designed to establish a multi-chain system compatible with Ethereum. It employs a proof-of-stake consensus mechanism similar to Ethereum for on-chain transactions, with its native token being MATIC. Functioning as a "layer two" or "sidechain" scaling solution alongside Ethereum, Polygon facilitates quicker transactions and lower fees. Its inception aimed to tackle Ethereum's major challenges, including high fees, subpar user experience, and limited transaction throughput, aspiring to create an "Ethereum's internet of blockchains" or a multi-chain ecosystem of Ethereum-compatible blockchains.

aelf is primarily a multi-chain parallel computing blockchain network which was created to address several of the limitations of traditional blockchain systems, such as performance bottlenecks and data complexity. aelf's vision is to be a 'Linux Ecosystem' equivalent for a blockchain that incorporates state-of-the-art IT design principles, which in particular allows developers to customise Chains to meet their own needs.
