Transaction-Driven Dynamic Reconfiguration for Certificate-Based Payment Systems

TL;DR

This paper introduces a transaction-driven dynamic reconfiguration protocol for certificate-based payment systems that enhances performance by avoiding global transaction ordering and enables smooth system reconfiguration.

Contribution

It proposes PDCC, a novel reconfiguration protocol that maintains system performance during configuration changes without disrupting ongoing transactions.

Findings

Achieves high performance by avoiding global transaction ordering.

Enables smooth reconfiguration without impacting system performance.

Demonstrates the effectiveness of the protocol in modern payment systems.

Abstract

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.
