RandAO (RNG) is a project focused on developing decentralized and verifiable Random Number Generator solutions for blockchain ecosystems. RandAO emerges as a randomness solution that is:
“What is scarce is valuable, in a deterministic world randomness is hard to come by.”
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.
“There is no truly random. There is only unpredictable.”
In the world of blockchain, randomness isn’t just hard — it’s inherently compromised by the very properties that make blockchains powerful: transparency and determinism.
Randomness in a blockchain context has to be unpredictable — and more importantly, equally unpredictable to all participants. That means no party should have privileged access to influence or predict the outcome of a random event. This is fundamentally at odds with trustless, permissionless systems.
Random numbers are vital: from cryptographic keys to fair games of chance, and even to video game mechanics like loot boxes. But onchain, randomness becomes a minefield of trust assumptions and attack vectors.
