Could you build this?
Partial The core web platform for hosting competitive tasks, leaderboards, and submissions is simple, but designing expert verification benchmarks and anti-gaming consensus mechanisms requires specialized data operations.
What it would actually take: The front-end and platform architecture uses Next.js, Postgres, and Celery/Redis for task queuing. The hard part is building automated consensus algorithms, evaluation sandboxes for verifying complex human expert submissions, and managing dynamic payout schemes that resist sybil attacks.
