I remember that there is a tx a4bfa8ab6435ae5f25dae9d89e4eb67dfa94283ca751f393c1ddc5a837bbc31b,
with its output "OP_HASH256 6fe28c0ab6f1b372c1a6a246ae63f74f931e8365e15a089c68d6190000000000 OP_EQUAL", which can be unlocked with the genesis block.

but if the redeem tx is released, it can be forged so anyone could spend it. some kind of risky.
