# Alea

> Stateless drand BN254 verification on Solana. MIT-licensed Anchor program. Fuzz-tested. Live on Solana devnet.

**For complete content, always fetch https://alea.so/llms-full.txt (docs + SDK reference dumped as plain text).**

Alea proves drand random beacons on-chain in approximately 407,000 compute units per verification. Stateless: no operator, no admin keys; upgrade authority planned to transfer to a Squads multisig and eventually be revoked (no fixed timeline). Public-good infrastructure for any Solana program needing unbiasable, verifiable randomness.
