Prediction Audit & Calibration Ledger

Tamper-evident forecast recording, verification and Brier-score calibration.

1. WHAT IS THIS?

The Prediction Audit & Calibration Ledger is a standalone Python library for quantitative funds, research desks, AI signal providers, and prediction markets to record pre-event forecasts in a continuous, tamper-evident cryptographic hash chain and score their realized accuracy using Brier scoring rules upon post-event resolution.

2. WHO IS IT FOR?

Quantitative researchers and algorithmic trading firms.
Prediction market operators and signal providers.
AI forecasting model evaluators seeking mathematical proof of model calibration.

3. WHAT PROBLEM DOES IT SOLVE?

Without pre-event cryptographic commitments, historical trading signals and prediction records are susceptible to "hindsight bias," cherry-picking, and retroactive tampering. Running full Web3 blockchain smart contracts for high-frequency predictions incurs prohibitive gas fees and leaks alpha publicly before execution. This ledger provides local, zero-gas, tamper-evident hash chaining.

4. WHY PAY FOR IT INSTEAD OF BUILDING IT?

Canonical Payload Serialization: Uses deterministic key sorting to guarantee that identical payloads always yield identical SHA-256 digests.
Tamper Evidence: Detects any retroactive field mutation, record deletion, or row reordering during chain traversal.
Calibrated Brier Scoring: Implements mathematically validated binary and multi-class Brier scoring algorithms ($BS = \sum (p_k - o_k)^2$).
Zero External Dependencies: Built 100% on Python 3.11+ standard library (hashlib, sqlite3, json, dataclasses).

5. WHAT IS VERIFIED?

7 / 7 Automated Unit Tests Passed: Reference mathematical Brier scoring, pre-event commitments, mutation detection, deletion detection, row swapping, SQLite database reopen, and 1,000-record scale test.
Microsecond Execution: Traversal and verification of 1,000 chained entries completes in < 15 ms.

6. HOW DO I RUN IT?

# 1. Run the unit test suite
python3 -B tests/test_ledger.py

# 2. Run the interactive verification demonstration
python3 -B examples/verify_predictions.py

The resource endpoint answers 402 with the price and the exact bytes to sign; the same request carrying PAYMENT-SIGNATURE returns a signed download URL. Access is granted only after settlement returns a transaction hash. A person can do the same thing with a browser wallet on the product page.

# the 402, with the price and the exact bytes to sign
curl -si https://x402git.com/api/r/genesiscode2026/prediction-audit-calibration-ledger

# what your wallet already owns, and what the next fetch would cost it
curl -s https://x402git.com/api/v/genesiscode2026/prediction-audit-calibration-ledger \
  -H "X-Wallet-Signature: 0xYOURADDRESS.<nonce>.<signature>"
