摘      要：One of the major concerns regarding currently proposed public blockchain systems relates to the feasible transaction processing *** is common for such systems to limit this rate to maintain the required levels of security and *** channels are an approach to overcome this limitation,as they aim to decrease the required on-chain transactions for a given application and thus indirectly increase the capacity(in terms of applications)of public blockchain *** the present paper,we propose a state channel design that,through the use of RSA accumulators,operates on a compact state *** scheme is optimal for applications whose state includes large sets of *** novel state channel design is presented by analysing all state channel operations and how they have to be *** security of the design is discussed,while a practical use case scenario regarding the use of the design for an on-chain asset(e.g.,non-fungible tokens)exchange application is also analysed.
