While AI can write any review, imitate any voice and flood any platform, authenticity becomes the new currency. McGesund Hearts are the counter-model: reviews are tied to a physical visit, quantum-resistantly signed, publicly anchored — still provably genuine ten years from now.
The profile of Optivisão was imported from our old portal or from OpenStreetMap and has no verified owner yet. By claiming it you get:
- Quantum-resistantly signed reviews. McGesund is the first review platform across the EU whose reviews are cryptographically protected against tampering with post-quantum signatures.
- Geo-verified reviews from your patients and customers. Only those who were really on site can sign a review.
- Full control over address, services, photos and replies to reviews. Plus an embeddable result widget for your own website.
- Blockchain-anchored and independently verifiable. Reviews are publicly anchored in a blockchain. Signature and anchor can be verified by any third party without you having to trust McGesund. Authenticity is proven, not promised.
Claiming takes just a few minutes and stays free forever. Upgradeable to Classic, Pro and Premium at any time.
Each claim is manually reviewed before activation.
