Roadblock Title:
The architecture of trust: Transaction integrity for distributed systems
Time:
Wednesday - 10:30 AM (Tower D)
Abstract:
In financial infrastructure, trust isn’t a buzzword, it’s an architectural decision. And when every inconsistency carries a price tag, transaction integrity becomes a foundational requirement, not just a technical detail.
This talk explores how to engineer transactional trust into large-scale distributed systems that weren’t born monolithic and must scale without compromising consistency or performance.
Fred Amaral (CEO) and Jefferson Rodrigues (CTO) of Lerian and the mind behind Midaz, an open-source ledger purpose-built for core banking, will share the architectural principles, design patterns and trade-offs that power scalable and auditable financial systems.
From two-phase commits and CQRS to idempotency and eventual consistency, the session offers a practical, code-informed perspective on combining these mechanisms to scale safely, building integrity that holds up in the real world, even with latency, network failures and parallel services in constant communication.
For engineers building the financial layer of the future, this isn’t theory. It’s infrastructure.
Bio:
Jefferson Rodrigues is the CTO and co-founder of Lerian, where he leads the development of scalable, auditable and open financial systems.
With over 10 years of experience in software engineering and infrastructure, he was responsible for the architecture of Brazil’s Pix system at Dock and led the full cloud migration of Elo Cartões, integrating more than 300 microservices.
An expert in distributed architectures and cloud environments (AWS and Azure), he’s fluent in technologies like Kubernetes, Lambda, Terraform and advanced cloud networking, always with a focus on reliability, performance, and security.
At Lerian, he created Midaz, the open-source core banking platform designed for distributed environments and institutions that demand full control over their infrastructure.
