sending, by the quantum system, the qubit |φrcustom character to each node in a validation set, wherein the qubit |φrcustom character is used by each node to create an entanglement system, of two other qubits, by applying CNOT gate between the qubit |φrcustom character as a control qubit and an ancilla target qubit that is initialized in a state |0custom character,
wherein each of the node in the validation set quantifies the degree of entanglement using a concurrence measure and wherein each of the nodes recognizes a selected leader node LN, wherein LN=fix (C×1014 mod v), and wherein the quantum system reduces hacking of linkages between different blocks of the blockchain based on the sending the qubit to each node in the validation set.
