# Quiver

> Verifiable on-chain randomness (VRF / RNG) for Robinhood Chain. Quiver is a two-party commit–reveal entropy protocol: the result is keccak256(userRandom ‖ providerReveal ‖ blockHash?), where both values are committed before either is revealed, so neither the requester nor the provider can bias the outcome. A fair result holds as long as either party is honest.

Quiver ships an on-chain coordinator contract (`QuiverCoordinator`), a keeper service
(Fletcher), a TypeScript SDK (`@quiver/sdk`), and example consumers. Brand names:
Quiver (the protocol) and Fletcher (the keeper); everything else uses standard VRF terms.
