Matching Engine Architecture
Engineering at the Landauer limit.
36M msg/sec.
Every exchange claims lock-free and zero-copy. The bottleneck was never concurrency—it's pointer chasing and cache misses. We eliminated both.

Engineering at the edge of what's physically possible
UNPRECEDENTED PERFORMANCE
In exchange technology, the matching engine's throughput is the critical factor that determines the exchange's order processing capacity.
MICRO-BURST RESILIENCE
Micro-bursts are concentrated orders in a fraction of a second that exceed typical engine capacity, causing queuing and latency spikes.
Our architecture eliminates queuing delays, protecting traders from execution risk and preventing revenue loss from delayed order placement.
PATENT-PROTECTED IP
Architecture protected by a patent portfolio covering the Priority-Indicated Node design, neighbor-aware tree operations, and hardware-accelerator embodiments. Multiple issued U.S. patents; international filings pending via PCT.
Core Architecture
Beyond lock-free. Beyond zero-copy.
Every production matching engine claims lock-free data structures and zero-copy paths. We solve the actual bottleneck: cache misses and pointer chasing in the single-threaded per-symbol matching loop under micro-burst conditions.
Traditional order books use linked lists (scattered memory, cache misses) or flat arrays (O(n) compaction on cancel). We introduce Priority-Indicated Nodes (PINs): fixed-capacity nodes with a contiguously addressable region of C logical slots, where each slot carries a per-slot priority indicator encoding the order's global priority status. Base-plus-stride arithmetic eliminates pointer chasing while bitmask-encoded indicators enable O(1) priority queries without scanning or compaction.
- →Contiguously addressable slot region with base/stride invariant
- →Per-slot priority indicators via bitmask encoding
- →Bounded relocation cascades capped at Dmax hops
- →95% cancel rate handled without O(n) compaction
