Polygon (previously Matic Network) aims to bring massive scale to the Ethereum blockchain using an adapted version of Plasma with PoS based side chains. According to the project, the current blockchain ecosystem is not prepared for the demand of all decentralized apps. The issues of slow block confirmations and high gas fees need to be solved before it's going to be adopted by the mass.

Consensus mechanism

The system ensures liveliness using PoS checkpoints which are pushed to the Ethereum mainchain. This enables a single Polygon sidechain to theoretically achieve 216 transactions per block, and possibly millions of transactions on multiple chains in the future.

Polygon wants to change the scaling problem and the interaction between users and the decentralized world. The project aims to make interacting with the decentralized ecosystem so easy that anyone can do so without worrying about the complexity of the system.

Polygon architecture

Polygon is building a decentralized platform using an adapted version of Plasma framework that provides a solution for faster and low-cost transactions with finality on the main chain.
