The Consensus layer is a scalable, high-throughput, secure, with decentralized set of validator nodes validator of the main differences with Etherem network is the Pivacy Dapps and better performance and almost 99% lower fees than Ethereum.
The ParaTime layer hosts many parallel runtimes (ParaTimes), each representing a replicated compute environment with shared state.
I really love this novel and innovation structure. this multi-layer structure is modular.
Modularity is very useful and you cant find in other evm-compatible networks.
you are free to choose your way and your programming language and logic.
