“What is scarce is valuable, in a deterministic world randomness is hard to come by.”

🌐 What is RANDAO?​

RANDAO is a decentralized protocol that provides verifiable, tamperproof, and unpredictable randomness — built for onchain use.

It uses a commit-reveal scheme fortified with Timelock puzzles, ensuring every output is not just secure but equally unpredictable to all participants. And it works fast, with just a small fee.

Whether it's for cryptographic keys, fair games, or loot mechanics, RANDAO solves the fundamental problem of randomness on blockchain — without compromising on decentralization or trustlessness.

🌟 Why It Matters​

The RANDAO protocol is Any-Honest — meaning as long as one honest provider contributes, the resulting randomness is secure. Even if others are compromised or malicious, the system holds up.

🔐 Key Benefits​

  • Unbiased & Tamperproof: No single party can influence the result
  • Permissionless & Decentralized: Trust the system, not the operator
  • Fast & Low-cost: Efficient enough for real applications

🎮 Practical Applications​

RANDAO’s decentralized randomness is already unlocking new frontiers across Web3 and beyond. Here’s how:

  • 🎮 Video Games: Power loot drops, matchmaking, and unpredictable NPC behaviors with tamperproof randomness.
  • 🎲 Lotteries & Gambling: Ensure fairness and transparency in outcomes without relying on centralized authorities.
  • 🎰 Casinos: Remove suspicion and build user trust with auditable, unbiased game results.
  • 🏛 DAO Governance: Use randomness to assign voting slots, random audits, or member selections — increasing fairness.
  • ⛓ Consensus Mechanisms: Improve unpredictability in leader election or validator selection in decentralized protocols.
  • 🔐 Cryptographic Key Seeding: Secure key generation backed by decentralized entropy instead of centralized inputs.

Decentralized trustless randomness isn’t just a technical upgrade — it’s foundational for systems that need fairness, security, and auditability without single points of failure.
