Question 2

Why do regular screenshots fail in court?

Accepted Answer

Regular screenshots lack cryptographic proof of authenticity and can be easily manipulated. Courts increasingly require evidence of integrity (SHA-256 hash), timestamp proof (blockchain anchoring), and chain of custody documentation. The EU's eIDAS 2 regulation (effective December 2026) establishes Qualified Electronic Ledgers as the standard for digital evidence, making simple screenshots inadequate for legal proceedings.

Question 3

What is blockchain timestamping and why is it important for evidence?

Accepted Answer

Blockchain timestamping anchors a cryptographic hash (SHA-256) of evidence to the Bitcoin blockchain via the OpenTimestamps protocol. This creates immutable, independently verifiable proof that the evidence existed at a specific moment in time. Unlike centralized timestamps, blockchain timestamps cannot be backdated or altered, making them ideal for legal evidence that may be challenged in court.

Question 4

Question 15

How do I spot a fake LinkedIn profile when recruiting?

Accepted Answer

Gartner predicts that by 2028, 1 in 4 candidate profiles will be fake. Red flags include: AI-generated profile photos (check for asymmetry, blurry backgrounds), inconsistent employment dates, vague job descriptions, few or no recommendations, recently created accounts with complete profiles, and connections that don't match claimed experience. Use ProofSnap to capture LinkedIn profiles before interviews — if the candidate later deletes or modifies their profile, you have blockchain-timestamped evidence of what it originally showed.

Question 16

What are the EU AI Act requirements for recruitment chatbots?

Accepted Answer

Under EU AI Act Article 50 (effective August 2026), recruitment chatbots must: clearly disclose they are AI systems to candidates, maintain an audit trail of all interactions, and ensure human oversight of automated decisions. Non-compliance can result in fines up to €15 million or 3% of global turnover. If your chatbot makes false promises to candidates (salary, benefits, job responsibilities), you may be liable. ProofSnap serves as an 'AI Flight Recorder' — documenting every chatbot interaction with blockchain timestamps for compliance and legal defense.
