Unlike traditional sharding designs, based on partitioning the state of the network, our solution centers on the concept of subnets -which are organized hierarchically- and can be spawned on-demand to manage new state. Child sub nets are firewalled from parent subnets, have their own specific policies, and run a different consensus algorithm, increasing the network capacity and enabling new applications. Moreover, they benefit from the security of parent subnets by periodically checkpointing state. In this paper, we introduce the overall system architecture, our detailed designs for cross-net transaction handling, and the open questions that we are still exploring.","lang":"eng"}],"department":[{"_id":"ElKo"}],"publication_status":"published","date_published":"2022-11-29T00:00:00Z","date_updated":"2023-08-04T09:06:02Z","article_processing_charge":"No","month":"11","day":"29","type":"conference"}
