Auditable randomness with VRF

Pass any 32-byte seed; the VRF derives an 80-byte proof and 64-byte deterministic output.

tenzro vrf prove --seed 0x$(openssl rand -hex 32) --out ./vrf.json

Verification is deterministic — same seed and key always produce the same output.

tenzro vrf verify --proof ./vrf.json

The VRF_VERIFY precompile at 0x1007 verifies on-chain in one call.

(bool ok, bytes memory out) = address(0x1007).staticcall(
  abi.encodePacked(pubKey, proof, seed)
);

The NFT factory's mintRandom() consumes the verified output to roll traits.

await tz.call("nft_mint_random", { collection: coll.address, to: buyer });
