  bibo_abstract:
  - We present the Filecoin Hierarchical Consensus framework, which aims to overcome
    the throughput challenges of blockchain consensus by horizontally scaling the
    network. 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.@eng
