The primary difference between Polygon (MATIC) and the Polygon Ecosystem Token (POL) lies in their respective roles within the Polygon network. MATIC is the native token of the Polygon network, and it is currently used for various purposes, such as staking and paying transaction fees on the network. However, as part of the Polygon 2.0 upgrade, the MATIC token is gradually being replaced by the POL token over four years.On the other hand, the POL token is designed to serve as the native token in the evolved Polygon 2.0 ecosystem. It is intended to offer enhanced utility, including features such as restaking, wherein validators can restake their POL tokens to secure other chains in the Polygon supernet and earn additional rewards.Furthermore, the transition to the POL token is a crucial aspect of the evolution of Polygon into a Polygon zkEVM validium network with its own network of interoperable application-specific blockchains. This upgrade reflects a shift towards integrating zero-knowledge technology and a full-suite scaling solution for the Ethereum blockchain, thereby differentiating POL from MATIC in terms of its intended functionalities and the ecosystem's future vision.While MATIC has been the native token serving various purposes within the Polygon network, the POL token is being introduced as part of the Polygon 2.0 upgrade to gradually replace MATIC and offer additional utility and features within the evolved Polygon ecosystem.
