Description
A consumer product labeling company has decided to certify its products using highly innovative NFTs. The company didn’t want to do things halfway, so they created their own blockchain.
Your friend, a sparkling wine producer, wants to take advantage of this to upgrade. With his computer skills, he managed to find a “pseudo-random” permutation used in the blockchain, and needs to solve the CICO problem to finally be able to sell champagne.
Can you help him?
