Digital game purchases can disappear if platforms revoke licenses or shut down. Gamers need verifiable proof they own what they've bought.
Create a service that generates cryptographically signed certificates of ownership tied to purchase receipts. Store them on decentralized storage to prevent tampering.
Gamers would pay for peace of mind knowing their collections are protected. Publishers might integrate to build trust.
Start with basic receipt imports and certificate generation for major platforms like PlayStation.
Biggest risk is platform cooperation - some might block automation accessing purchase histories.
