Throughput claims only matter if they are repeatable. And repeatability is not just an NFR concern: stable performance under sustained load often translates directly into better functional outcomes; enhanced consistency in transaction finality, reducing the necessity for retries and minimising edge-case latencies that can emerge during peak-volume periods. In Kubernetes, repeatability often comes down to… Read More »Replica Configuration, Scheduling, and Repeatability (Part 5 of 6)

Kafka provides a high-throughput eventing backbone for Mojaloop, achieving maximum performance at scale when partitioning, ordering assumptions, and handler concurrency are expertly aligned with the expected workload. In Mojaloop v17, a key performance theme was revisiting message flow design so the switch can process work in parallel without breaking correctness. The Engineering Problem Mojaloop follows… Read More »Kafka Design for Real Throughput: Partitioning, Ordering, and Concurrency (Part 4 of 6)

To fully leverage the high-performance capabilities of the core services, the ingress layer, or ‘front door’, must be engineered to meet the robust throughput requirements of national infrastructure. In Mojaloop v17, we modernised the gateway layer to unlock the performance of the hub. By replacing earlier components with high-performance alternatives, we ensured that the edge… Read More »Removing Bottlenecks at the “Front Door” (Ingress and Gateway Path) (Part 3 of 6)

Throughput improvements often come from removing avoidable per-transaction overhead, especially in the critical path of a transfer. In Mojaloop v17, a large part of the work was exactly that: take the hottest paths in the switch, reduce the number of round-trips and repeated work, and do it without breaking correctness or security assumptions. The engineering… Read More »Batching, Caching, and Cutting “Chatty” Work (Part 2 of 6)

Mojaloop is increasingly being relied upon as a national and regional payment infrastructure. In that role, trust depends not only on performance but also on consistent availability, operational resilience, and the ability to operate reliably over sustained periods. Scheme operators and central banks, therefore, need clear evidence that the switch can handle real-world transaction volumes… Read More »Building World-Class Mojaloop Platforms Together (Part 1 of 6)

Proof of concept completed Introduction: Similar to the recent dominance of AI breakthroughs in the startup industry, the remittance market is experiencing significant growth, with anticipated growth projected to soar even further. This surge is propelling central banks, financial service providers, and fintechs to innovate. Responding to this need, the Mojaloop community has unveiled an… Read More »Integrating Native Foreign Exchange Services into Mojaloop
