Blockchain-Authenticated Communication Subscription System

Resumen de: US2025131415A1

A blockchain-authenticated communication subscription system that leverages smart contracts and non-fungible tokens to verify the ownership and authenticity of communication channels. The platform allows creators—individuals or organizations—to authenticate their identity by proving ownership of a smart contract or non-fungible token through cryptographic wallet signatures. Subscribers can opt into these subscription services and receive communications exclusively from verified creators, enhancing trust and reducing unsolicited messages. The system supports both cryptographic wallet-based and traditional authentication methods for subscribers. Communications can be delivered through secure channels and may be stored on-chain or referenced on-chain linking to off-chain data, ensuring transparency and immutability. The platform can be implemented using centralized, decentralized, or hybrid infrastructure to manage subscription data while maintaining authentication integrity. This invention provides an effective solution to unsolicited communications by verifying message origins through blockchain technology, minimizing reliance on traditional spam filters, and delivering a secure and trusted communication experience.
