High-Frequency Institutional Distributed Ledger & FedNow API Engine
Engineered an institutional-grade, double-entry financial ledger platform capable of sub-15ms transaction processing and PCI-DSS v4 compliance.
articleExecutive Overview
Meridian Capital Partners processes institution-to-institution liquidity transfers and instant payment settlements. As processing volume grew past $50M daily, their legacy core banking middleware struggled with thread contention and audit reconciliation lag.
warningThe Operational & Technical Challenge
High transaction concurrency caused audit log discrepancies and processing delays, failing FedNow instant settlement requirements and creating compliance friction during regulatory reviews.
Concurrency Bottlenecks
Legacy middleware failed to maintain ACID compliance under 10,000+ concurrent requests per second.
Strict Regulatory Audits
Required immutable, tamper-evident audit logs adhering to PCI-DSS v4.0 and SOC 2 Type II.
Sub-Second SLAs
Financial counter-parties mandated instant settlement finality under 50 milliseconds.
