Designed to be a scalability solution, Supernet is the Polygon network’s blockchain development platform that aims to help developers create their own blockchain protocols in a cost-efficient way.;
Developers building on the Polygon network can access a wide range of validators and tools for effortless integration and third-party services to assist with implementation, design and management. Technically, supernets work on problem-solving for Polygon’s development framework, Polygon Edge. Polygon Edge helps build Ethereum-compatible blockchains while keeping them secure, decentralized and efficient.
The big picture concept of supernets is that they are collections of interconnected networks that promote collaborative work while serving as a secure data-sharing hub. They can hold and organize large quantities of data and facilitate communication among users. The benefits of using Polygon supernets include interoperability, specificity, enhanced scalability, security and better decentralization. Supernets also address Polygon Edge’s technical challenges really well, especially regarding chain configurations and bootstrapping decentralized validator sets.
