Case 05 / Blockchain / media verification
Crypto wallet claim
Assess a political or institutional donation claim by checking source authenticity, wallet evidence, and whether a transaction can be verified.
Real-case basis: A fake BBC/Bellingcat-style video claimed Ukrainian business figures donated crypto to a US campaign.
Data package
A short video using the visual style of known media brands
Named people, dates, amounts, and claimed wallets
Search results from the real publishers and campaign channels
Wallet address or transaction hash if one is provided
Task
Check whether the named publishers actually released the video.
If no wallet or transaction hash exists, state that the claim cannot be verified on-chain.
Assess whether branding, wording, and source absence point to a fake report.
Hint
A claimed amount is not blockchain evidence.
A real news video should leave a trace on the publisher's own channels.
Brand impersonation and crypto claims require two separate checks.
Answer key
The video was not published by the claimed outlets.
No verifiable wallet or transaction evidence was supplied.
A careful result marks the claim as unsupported and likely built on source impersonation.
Weak analysis example
The video looks professional and uses major media logos, so the crypto transfer probably happened.
Careful report example
The claimed publishers do not show the video in their official archives. The video provides no wallet address or transaction hash. Because the branding does not match an official channel, the claim should be treated as unverified and likely false-source material.
