The diversification of crypto assets in recent years has increased the demand for decentralized finance. In order to realize decentralized finance, Interoperability, which is the property of being able to read and write the information on BC from other BC to each other, and the processing power of BC are important, and BC projects to realize this have been proposed. We have proposed a chainless multi-tier agreement composed of multiple BCs. In this study, in order to implement the proposed method more safely, we perform experiments when the block generation time interval is non-uniform between BCs, and propose a process to determine the multilayer consensus time interval and node role from the experimental results. In this paper, we consider and report on the incentive design considering the security that motivates more participating nodes to participate in multi-level consensus, and the security measures such as impersonation attacks and block hiding attacks that are assumed to be necessary for chainless multi-level consensus. |
