Kurrent (formerly Event Store)

This skill enables the formal verification of event-sourced aggregates by applying property-based testing. It allows engineers to define invariants and explore state spaces to identify potential inconsistencies or logic errors within event-driven domain models before deployment.

This skill is designed for distributed systems engineers, domain-driven design practitioners, and backend architects. It is specifically targeted at professionals managing complex event-sourced systems who require rigorous validation of aggregate state transitions and business logic consistency.

Implementation requires an existing event-sourced architecture utilizing event-store patterns. Engineers must define formal properties or invariants for their aggregates, which the verification engine then uses to perform state exploration and identify violations of defined business rules.
