Verifiable-From-Public-Data Strategy-Validation Backtest.

Backtest reports anyone can verify against public exchange data. 20 claims.

A method for producing a strategy-validation backtest record that any third party may verify against public exchange data alone. The producer captures the canonical input set (starting capital, candidate-market filter, window timestamps, venue endpoint reference), queries the venue's public price-history endpoint for every market resolving in the window, executes a deterministic cascade computation, and computes a SHA3-512 integrity hash over the canonical-JSON serialisation of input plus output. The published report carries the input, the cascade trajectory, the hash, and a verifier-instructions block. Any verifier given only the input may re-execute the cascade against the public endpoint and recompute the hash; byte-identical hashes confirm the report. Optional ML-DSA-65 (FIPS 204) signature anchors operator origin. Filed 19 May 2026 as GB2611681.4.
