Published with \"The World's Fastest Matching Engine Algorithm\" (Flash One Technologies, 2026).[^paper] The survey aims to cover every publicly available FIFO matching implementation without duplicates; to request coverage of an engine, contact contact@flash1.com. Results The harness has been run against 247 distinct matching engines — every common FIFO book architecture, 20+ source languages. 160 reproduce the byte-identical consensus (113 of them only after a documented correctness fix at their pinned commit; three have since merged that fix upstream and now conform as shipped, so 110 still carry ours) and are listed in CONSENSUS CONFORMING ENGINES.md ; the other 87 diverge, cannot finish their slowest scenario within the message budget, or crash ( NON CONFORMING ENGINES.md ). The consensus oracle is also a bug-finder: across the 247 engines tested, wherever it surfaced a reportable finding we drafted a fix and reported it, respectfully: 181 GitHub issues filed upstream for +250 distinct findings — 25 already fixed by their maintainers, none declined ( RESOLVED FINDINGS.md ). The full decomposition and per-engine one-line findings are in CORRECTNESS FINDINGS.md ; the industry-authored subset is broken out in INDUSTRY AUTHORED ENGINES.md .
