How it works?

To generate the timestamp symbol, first we put the 5 QBITs of the IBMQX4 Quantum Computer in the superposition quantum state multiple times to generate a real random number, we save the IBMQ output in a Interplanetary FileSystem node, becoming this a quantum-proof-of-work that gives an added value to the ownership. We use that random number to select one of the runes of the Runic Unicode block, and then we save the timestamp, IPFS links and Quantum result in the Ethereum Blockchain.
