Abstract: Maintaining consistency and scalability together with auditability across complex microservices architectures in contemporary distributed systems presents new challenges. Traditional centralized database systems face challenges because of their strong coupling, as well as insufficient tracing capabilities and problems with maintaining data integrity across distributed service boundaries. Asynchronous communication patterns help event-driven systems overcome some decoupling issues, but they frequently lack centralized authoritative record-keeping mechanisms for state transitions. Although ledger-based systems offer extensive traceability through cryptographic verification and mathematical immutability guarantees, they usually function independently of larger event-driven infrastructure. This creates architectural gaps where organizations maintain parallel systems for operational events and audit compliance, leading to data duplication and synchronization overhead. By combining immutable state recording with real-time system behavior coordination, the suggested ledger-centric, event-driven architecture positions the ledger as the active engine for state evolution and the ultimate source of truth. The four interrelated levels of the framework—Event Ingestion, Ledger, Processing and Projection, and Audit and Compliance—are individually made to manage workloads at the enterprise level while maintaining the promises of mathematical immutability. Event immutability and self-contained data structures are prioritized by implementation guidelines to guarantee processing dependability and state consistency across dispersed transaction boundaries, with the ultimate system source of truth being the ledger, while idempotency patterns are applied exhaustively.
