As answered by people managing replit and Forecast Library.
Forecast Library's answer:
Forecast Library preserves individual forecasts as portable Open Forecast Receipts: original values, generation time, forecaster identity, declared knowledge boundaries and provenance, with a deterministic SHA-256 digest. Readers can browse public records without an account, download structured JSON, and independently verify that a receipt has not changed. Later evaluations and corrections are separate records. Optional blockchain anchoring provides evidence of integrity and timing; it does not prove forecasting accuracy. The public library and MIT-licensed schema/verifier are available today.
Forecast Library's answer:
Choose Forecast Library when the task is preserving and inspecting individual forecast records with a portable, independently verifiable receipt. General research repositories such as Open Science Framework can preserve broader research materials; Forecast Library specialises in forecast subjects, targets, forecasters, receipt integrity and separately appended outcomes. It complements broader research workflows rather than replacing their collaboration features. Public access is free, and iPulse AI is the first production publisher.
Forecast Library's answer:
Researchers, forecasters, analysts and developers who need to preserve a prediction, inspect its provenance, verify its integrity and revisit it when the outcome becomes known. The first live use case is financial research, while the underlying receipt structure supports human, quantitative, ensemble and AI forecasts. Public browsing does not require an account. External publication requests are reviewed through support@ipulseai.com during this phase.
Forecast Library's answer:
Forecast Library grew from Open Forecast Receipt, an open-source initiative by Future Edge Group for portable, verifiable forecast records. It addresses a practical research problem: preserving what was predicted, by whom and with which declared information boundaries before later outcomes are known. iPulse AI is the first production publisher. The library makes those records browsable and downloadable while keeping integrity verification distinct from forecasting performance.
Forecast Library's answer:
The public receipt protocol uses a versioned JSON Schema, RFC 8785 canonicalization and SHA-256 payload digests. Structured receipt JSON and the open schema/verifier allow independent integrity checks. The schema and verification tools are MIT licensed at https://github.com/TheFutureEdge/open-forecast-receipt. Optional blockchain attestations add a separate timing/integrity proof layer; they are not required for local verification.
