Public attestation record for QuantGPT quantitative trading signals.
Before each trading session, we commit a JSON file containing the SHA-256 hash of every active strategy signal. Git commits are timestamped and immutable once pushed — this serves as tamper-proof proof that signals were generated before market open, not retrofitted after the fact.
All commits are GPG-signed by QuantGPT Attestation <attestation@quantgpt.dev> (key fingerprint 196CC5B1E2DE02EE2BE05C5D3F649E566F7F506C). The public key is included in this repo as GPG_PUBLIC_KEY.asc.
# Import the public key

git log --show-signature
# Verify a specific commit
git verify-commit <commit-hash>A valid signature proves the commit was made by the QuantGPT platform — not by someone who cloned or forked this repo.
- Pick any file in
attestations/, e.g.2026-05-13.json - Each entry contains a
signal_hash(SHA-256 of the raw signal JSON) - Cross-reference the Git commit timestamp — it must predate market open (09:30 CST / UTC+8)
- The hash can be independently verified against the signal data served by the QuantGPT platform
