Toph Case Study
Toph is where competitive programmers compete, practice, and grow. The platform hosts contests, curates thousands of algorithm and data structure problems, and brings together a global community of developers who take their craft seriously.
But running a platform like Toph isn’t just a software challenge — it’s a security and infrastructure challenge. Every submission is arbitrary code from an anonymous user. Every contest is a live event where thousands of people are watching a leaderboard refresh in real time.
