[Suspected Lighter Prediction Market Mechanism Revealed: Proposed Adoption of HIP-3 Style Whitelist Operation Model] Deep Tide TechFlow reports that on September 21, the decentralized order book exchange platform Lighter's codebase recently included a commit titled 'Binary options support,' indicating that its ZK Circuits may have begun supporting binary outcome markets (prediction markets). According to the code, each market has a settlement cap, with share prices trading between 0 and the cap, and settling either at zero or the cap upon conclusion. Contracts are fully collateralized by USDC, thus avoiding leverage and liquidation risks. Analysis suggests that Lighter may introduce a 'market operator' model, allowing whitelist-approved operators to create, manage, and oversee market settlements, resembling the deployment model of HIP-3.
