Polygon 2.0: ZK-driven L2 sidechain network

**Polygon is a Layer 2 expansion solution that solves the scalability and transaction speed problems of the Ethereum network, while improving the usability and user experience of decentralized applications. ****Polygon's vision is simple: to build the value layer of the Internet. ** Just like the Internet allows anyone to create and exchange information, the value layer is the underlying protocol that allows anyone to create, exchange, and program value. The internet democratized access to information; the layer of value democratized access to the global economy. It enables decentralized finance, digitized ownership, new coordination mechanisms, and more. It is a missing part of the current Internet, and it only serves users rather than industry giants, industry monopolies or middlemen.

**As version 2.0 of Polygon, Polygon 2.0 is a blueprint and an important module for building a value layer. **It is a set of proposed upgrades that completely reimagine almost every aspect of Polygon, from protocol architecture to token economics to governance. Ethereum was the first to introduce the concept of a value layer. It demonstrates that people can seamlessly and securely create, exchange and program value without middlemen. But Ethereum and the cryptocurrency ecosystem are currently not similar to the rest of the internet.

The Internet as we know it is infinitely scalable and unified. Specifically, infinite scalability means that the throughput of the Internet has the ability to expand elastically, and when we need more capacity, we can build it. Uniformity, on the other hand, means that information can be accessed from anywhere in the world as long as it exists in a shared environment. As far as blockchains are concerned, the scalability of individual blockchains is limited, and they have strict throughput limitations. We can increase capacity by creating new blockchains, but doing so destroys liquidity, reduces security, and reduces capital efficiency.

**Polygon2.0 was born to solve these traditional blockchain problems. Polygon 2.0 is a ZK-driven L2 sidechain network, unified through a novel cross-chain coordination protocol. **For users, the entire network will feel like using a single chain. The network can support a virtually unlimited number of sidechains, and cross-chain interactions can occur securely and instantly without additional security or trust assumptions. It is characterized by unlimited scalability and unified mobility.

Polygon 2.0 will be a value layer similar to the rest of the Internet, and it will expand Ethereum to a network that enables seamless and secure value creation, exchange, and programming, becoming a value layer in the true sense. And for the Polygon ecosystem, which has a formal governance process and continues to expand the power of the community, the roles of builders, creators, and all others involved in the Polygon ecosystem are more relevant than ever.
