Scalable Trading

Overcoming micro-action bottlenecks and database lock contention on active fractional prediction markets.

Finfeed combines social interaction with prediction market contracts. When high-impact financial news breaks, thousands of users buy and sell outcome shares simultaneously. Processing social feeds alongside volatile prediction transaction queues creates massive database challenges.

GCAN resolved these throughput requirements by implementing isolated transaction routing layers. Market actions are processed via memory-mapped Redis queues before committing to SQL storage records, preventing database lock contention. Real-time updates stream across both Next.js Web channels and native Flutter application sockets, syncing portfolios under 150ms.

Real-time Sockets

Streams market quotes and feed updates dynamically via WebSockets.

Fractional Markets

Supports low-value contract actions using high-precision database fields.

Market Simulator

Select a contract topic, set your target share volume, and execute a simulated order request.
