BlockBriefing checks important news claims against identifiable evidence before labeling an article as source-verified. This desk documents the specific claims checked, the original sources and the limits of each review. The aim is accurate reporting, not to give every article a positive rating or promise that mistakes can never occur.
Latest listed editorial review: October 27, 2026. Entries below relate only to the linked articles and the facts described. Other published articles must be reviewed separately before carrying a verification badge.
Reporting verified against original announcements

What a verification check mark means
A Fact Checked mark indicates that the article has completed a documented editorial review of material factual claims against cited evidence. It does not mean endorsement by Google, a regulator or an independent external fact-checking organization, nor does it certify future price forecasts or an investment recommendation.
We do not automatically add badges to every historical article. A reviewer must first examine the article itself, trace material claims to primary records, inspect dates, numbers and context, and document the relevant sources. Unverified or unreviewed items remain without the mark.
Pre-publication verification requirements
- Original evidence: Prefer regulators, court or company filings, official announcements, direct blockchain records and authenticated first-hand statements. Attribute claims from interested parties rather than adopting them as established facts.
- Numbers and timing: Cross-check amounts, dates, time zones, token symbols, denominators and differences between estimates. Timestamp changing market and on-chain metrics.
- Context and limitations: Separate what is observed from what is alleged, projected, interpreted or not yet independently confirmed. Do not treat an announcement as proof of execution or adoption.
- Visual evidence: Use authentic charts or clearly labeled editorial graphics with source citations and accurate captions. Never invent price movements or data.
- Final review: Check headline and body consistency, original outbound sources, author attribution, correction notes, and any fact-check badge before publishing.
Corrections, updates and contested claims
A published check is specific to the evidence and the review date. If a new filing, transaction or official correction changes material facts, we will amend the story and explain the change. An uncertain or disputed claim cannot be made “verified” simply to improve an article’s appearance.
Standalone fact checks of statements made by others will identify who made the claim, the exact statement, the underlying evidence and the conclusion. They will not be used as a mechanism for awarding flattering ratings to our own work. We do not apply ClaimReview structured data to ordinary news stories or self-certification badges.
