Generate random number

Random encrypted integers can be generated fully on-chain.

That can only be done during transactions and not on an eth_call RPC method, because PRNG state needs to be mutated on-chain during generation.

WARNING: Not for use in production! Currently, integers are generated in the plain via a PRNG whose seed and state are public, with the state being on-chain. An FHE-based PRNG is coming soon, where the seed and state will be encrypted.


euint8 r8 = TFHE.randEuint8();
euint16 r16 = TFHE.randEuint16();
euint32 r32 = TFHE.randEuint32();
euint64 r64 = TFHE.randEuint64();
