Verifiable Random Tools

Verifiable Random dice — unbiased dice rolls bound to a future drand round the server waits for (typically 3-6s) and verifies locally, with a reproducible proof transcript.

Verifiable Random pick — string selection with or without replacement bound to a future drand round the server waits for (typically 3-6s) and verifies locally, with a reproducible proof transcript.

Verifiable Random shuffle — a uniform Fisher-Yates permutation bound to a future drand round the server waits for (typically 3-6s) and verifies locally, with original indices and a reproducible proof transcript.
