in today's world where energy is very important thing to talk about. because people specially the leaders are very much concern about it. On this situation energy saving idea would be a great idea. Blockchain industry have to accept it because it's the latest technology.
Determining which validators are in the active concentration and which nominators are nominating them is a computationally intensive task, resulting in very large graphs that map the nominators to their respective validators. The generated graph is calculated off-chain and submitted back to the chain, which means it must fit in a single block.
When it comes to blockchain architecture, one size cannot fit all needs. All blockchains must be weighed to support different functions and use cases. For example, one chain might optimize identity management, while another might optimize file storage.
