Questions & Answers

As answered by people managing React Native Paper by Callstack and CHECKHC.

Why should a person choose your product over its competitors?

CHECKHC's answer:

CheckHC is the only consumer solution combining AI deepfake detection, official C2PA certification, blockchain registration, and permanent Arweave storage (200+ years) in one click.

All-in-one: Competitors offer pieces (OpenSea = NFT only, Truepic = C2PA only). CheckHC combines everything.
Real minting: Unlike OpenSea's "lazy mint," CheckHC actually mints your NFT on Solana immediately.
GDPR compliance: Unique "Flexible" option allows content deletion for European regulations.
90% creator royalties: Higher than Foundation (85%) and SuperRare (85%).
Affordable: Document certification from €0.09, photo with AI from €2.70, full NFT from $38.50.

How would you describe the primary audience of your product?

CHECKHC's answer:

Professional photographers protecting their work from theft and AI manipulation
Digital artists & NFT creators wanting permanent, verified ownership with high royalties
Content creators & journalists needing proof of authenticity in the deepfake era
Inventors & entrepreneurs protecting patents and ideas affordably
Legal professionals & businesses requiring blockchain-based notarization at a fraction of traditional costs

What's the story behind your product?

CHECKHC's answer:

CheckHC was born from a simple observation: in a world flooded with AI-generated content and deepfakes, proving authenticity is becoming impossible.

Founded in France, CheckHC gives creators a simple, affordable way to certify their digital content before it gets stolen or manipulated. We believe every valuable digital content will soon need a "birth certificate" - and CheckHC provides exactly that.

Our mission: make digital authenticity accessible to everyone, not just corporations with enterprise budgets.

Which are the primary technologies used for building your product?

CHECKHC's answer:

Next.js - React framework for frontend
Solana - Fast, low-cost blockchain for NFT minting
Arweave - Permanent storage (200+ years guaranteed)
Custom AI model - Deepfake detection
C2PA standard - Coalition for Content Provenance and Authenticity certification

Who are some of the biggest customers of your product?

CHECKHC's answer:

CheckHC just launched publicly in January 2026. We're currently onboarding our first customers:

Independent photographers and digital artists
Small creative agencies
Content verification early adopters

We're offering special early-adopter pricing for professionals who want to be among the first to protect their digital assets.

What makes your product unique?

CHECKHC's answer:

CheckHC is the only platform that combines in a single click:

AI deepfake detection - Verify your content is authentic
C2PA certification - Official industry standard (we're a member)
Solana blockchain - Immutable proof of ownership
Arweave storage - 200+ years permanent preservation
GDPR compliance option - Unique "Flexible" NFT with deletion rights

No competitor offers all of this. OpenSea has no AI, no C2PA, no permanent storage. Truepic is B2B only at $$$. Reality Defender has no blockchain, no NFT.

CheckHC = digital birth certificate for your creations, from €0.09.
