RewInt
RewInt is a specialized integer data type introduced in 2015 for use in the Real-time Event Workflow (REW) software framework. The type is designed to support efficient replay of event logs and to provide deterministic integer values for scheduled tasks, ensuring consistent behavior across distributed nodes. RewInt extends the conventional 64‑bit signed integer by embedding a sequence hash that is automatically updated each time the value is modified, allowing automatic detection of duplicated or out-of-order updates within the event stream.
The RewInt type was implemented in the core of the REW framework by the Institute for Distributed
In practice, RewInt is used to annotate timestamps, transaction IDs, and state machine counters in event‑driven
RewInt has been adopted in several commercial products from the fintech sector, including the LedgerSync platform
RewInt continues to be studied for potential applications in blockchain technology, where deterministic replay and tamper‑proof
