StreamFlow
https://github.com/Sahid-m/radix-hack
Streamflow is a decentralized tipping platform designed for content creators and streamers. The platform aims to provide an alternative to traditional streaming services like YouTube and Twitch by eliminating commission fees typically charged by these platforms when viewers send tips to their favorite creators.
Technology and Features
Streamflow operates using blockchain technology and smart contracts. The platform's key innovation is its batch processing system, which uses Radix subintents to collect multiple tips together before sending them to creators. This batching mechanism is designed to reduce transaction fees (gas fees) by processing multiple payments simultaneously rather than individually.
Users connect their cryptocurrency wallets to the platform and can select creators to support using various tokens. The system accumulates tips in batches and automatically distributes them to creators once predetermined thresholds are reached.
User Interface
The platform provides analytics dashboards for both tippers and streamers, displaying statistics such as tip amounts, frequency, token types used, and creator rankings. Users can track their tipping history and view comprehensive analytics about their platform activity.
Purpose
Streamflow was created to address what its developers view as a monopolistic practice by major streaming platforms that take commissions from creator tips. The platform positions itself as ensuring that creators receive the full amount of tips sent by their supporters without third-party deductions.
