Interoperable validators are responsible for achieving direct transmission between different consortium chain ledgers, while overlay networks ensure that the network can continue to function even if some validators are turned off or not participating. This solution follows design principles of plug-and-play models and components, flexible requirements and data protocols, and leveraging existing roles. As a result, communication between consortium chains is enabled, breaking the limitations  of information islands."}]}],"pr":"73956e31149cadc33db25567dfcbfcebe1307f803d209e40aa9cf03435b73e6f"}
