Transaction-Driven Dynamic Reconfiguration for Certificate-Based Payment Systems
We present a transaction-driven dynamic reconfiguration protocol in Modern payment systems based on Byzantine Consistent Broadcast which can achieve high performance by avoiding global transaction ordering. We demonstrate the fundamental paradigm of modern payment systems, which combines user nonce based transactions ordering with periodic system-wide consensus mechanisms. Building on this foundation, we design PDCC(Payment Dynamic Config Change), which can lead a smooth reconfiguration process without impacting the original system's performance.
