A Blockchain-Driven Architecture for Secure Software Distribution and License Validation

Software theft’s a global issue – costs tons of cash, slows down innovation. Older methods to track usage, such as license keys or mainframe checks, aren’t secure; they get cracked or faked pretty quick. So this study offers a fresh setup using blockchain tech for handling software access and cutting illegal copies. It keeps digital goods safely distributed, clear to see, tamper-proof. This system locks files with AES-256, stores them on IPFS so no single party controls access, while Polygon’s smart contracts manage licenses via NFTs – handling both setup and removal. Licenses get bought on a peer-to-peer marketplace; safety gets boosted thanks to locked wallets, device tracking, plus live chain verification. Findings confirm it blocks unauthorized copying, simplifies proof of ownership, also increases confidence compared to old-school approaches. It proves blockchains can reshape digital rights control, offering practical fixes for secure app distribution or fighting leaks.
