Project Description

Real-time betting and prediction markets within streaming platforms (Twitch, Kick) face two main challenges when trying to use Web3 technology:

  1. High Costs and Latency: Prediction systems that use the main blockchain on-chain are inherently slow and generate high transaction costs gas fees. This makes them unviable for live events, where action is instantaneous and requires immediate response and settlement.
  2. Lack of Web3 Experience: Our team identifies primarily as backend and frontend developers with limited experience in Web3 development, which requires a protocol that simplifies the implementation of decentralized transactions.

How it's Made

🎯 Yellow's Role in the Solution

Yellow is an off-chain network designed for games and applications that demand instant user actions.

Fast and Gasless Transactions: Yellow allows transactions and bets to be made off the main chain, eliminating gas fees and ensuring that user actions (such as placing a bet) are instantaneous. Viable Prediction Markets: This makes the "Polymarket for a streamer" model feasible, as bets and settlement can occur at the speed of a live event.

🛠️ Technology Stack

Frontend/Backend: Next.js, Unified development stack known by the team for rapid implementation. Database: Supabase (Postgres), Using the API wrapper for a ready-to-use and easy-to-integrate backend. User Interface: Bolt, Tool to accelerate frontend scaffolding and quickly generate a functional design (similar to Polymarket). Main Protoco: Yellow, The pillar of the solution: Enables fast and gasless off-chain transactions for live prediction markets. Data Source: Twitch/Kick API, Will be used to obtain information about live streams (e.g., simple metrics, list of streams).
