Blockchain Fan Loyalty App Stores Streaks on Solana

A developer built Loyalty Ledger, a fan loyalty tracker that stores check-in streaks and badges on the Solana blockchain instead of a central database. The app lets users connect a wallet, pick a team, and check in via an on-chain transaction that creates or updates a program-owned account. The project aims to give fans true ownership of their loyalty history, which is currently controlled by individual apps.
