What is drand? drand<\/a> (pronounced \u201cdee-rand\u201d) is a decentralized, verifiable, and unpredictable randomness generator. Its random numbers are not generated by any single entity, but are collectively computed in real time by the \u201cLeague of Entropy<\/a>\u201c\u2014a global consortium of leading tech organizations and academic institutions, including Cloudflare<\/a> (the global network security giant), Ethereum Foundation<\/a>, Protocol Labs<\/a>, and EPFL (Swiss Federal Institute of Technology Lausanne). Consequently, it mathematically guarantees unpredictability, immutability, and publicly verifiable fairness and transparency.<\/p>\n<\/blockquote>\n\n\n\n

\ud83c\udf1f Overview<\/h2>\n\n\n\n

cloudflare-drand-verifier is a serverless, single-page random number generation system. Every calculation is performed directly within each user’s browser, ensuring that the generated results cannot be manipulated by anyone. It serves as a decentralized and provably fair randomness verification tool.<\/p>\n\n\n\n

The system combines the Cloudflare Distributed Randomness Beacon with the drand network. By locking in a future timestamp before the draw takes place, it ensures that no one can predict or manipulate the outcome before the randomness is generated.<\/p>\n\n\n\n

Once the draw concludes, a unique permalink is generated for that specific draw page. Anyone can recalculate and verify the results at any time using the computation report provided on the permalink page along with public drand data\u2014ensuring complete transparency and immutability.<\/p>\n\n\n\n

\ud83d\udca1 Quick Tip: The simplest way to verify is to copy the entire computation report from the page and paste it into any AI tool (such as ChatGPT, Gemini, Grok, or DeepSeek) and ask it to recalculate and check the steps for you!<\/p>\n<\/blockquote>\n\n\n\n

The verifier codebase has been open-sourced on GitHub, allowing anyone to review it.<\/strong><\/p>\n\n\n\n
