Fact-Checking Policy

Source hierarchy

1. On-chain data (block explorers, network statistics).
2. Primary documents (regulatory filings, manufacturer specifications).
3. Peer-reviewed academic research.
4. Our own bench testing and screen captures.
5. Reputable journalism with named, verifiable sources.

What we never use as a source

• Anonymous Telegram or Discord screenshots.
• Affiliate review aggregators.
• Press releases reported without independent verification.
• Social media testimonials.

Verification workflow

Before publication, every quantitative claim, product specification, and historical date is checked against at least one source from the hierarchy above. Where sources disagree, we present the range and the rationale for our chosen figure.

Updates

Bitcoin mining is a fast-moving field. Cornerstone articles are reviewed every six months and updated when difficulty, hash rate, or hardware availability change materially.

Reader corrections

If you spot an error, please email corrections@hashledger.example with the article URL and the specific claim. We aim to respond within 5 business days.
