SubStream Protocol: Decentralized Creator Economy

Overview

SubStream is a Pay-As-You-Go subscription protocol. Instead of monthly credit card charges, fans stream tokens to creators second-by-second. If the fan dislikes the content, they can cancel instantly and get their remaining balance back.

Key Logic

• subscribe: User deposits a buffer (e.g., 50 XLM) and sets a rate.
• collect: Creator triggers the withdrawal of accumulated seconds.
• cancel: Subscriber stops the stream and refunds unspent tokens.
