Cellframe Network is a scalable, open-source, next-generation platform for building and bridging blockchains and services secured by post-quantum encryption. Cellframe offers an environment for enterprises and developers to build a vast array of products ranging from simple low-level t-dApps to whole other blockchains on top of Cellframe Network. Cellframe can provide extremely high transaction throughput based on an original sharding implementation. In addition, post-quantum cryptography makes the system resistant to hacking by quantum computers.
