An integrated circuit comprising a CPU coupled to a system bus, a network interface configured to interface with an external device, and a crypto neuromorphic core coupled to the system bus. The cryptographic core comprising a processor or core, an internal bus, and a non-transitory computer-readable memory, wherein the crypto neuromorphic core is isolated from the CPU and the network interface via the system bus and the crypto neuromorphic core runs its own operating system. The crypto neuromorphic core is configured to: contain a secure core comprising a secure processor and dedicated/protected memory; store a private key in the dedicated/protected memory accessible to the secure core but not accessible to other components of the crypto neuromorphic core, the central processing unit, and the network interface; add data to a blockchain using the private key via the network interface; and read data from the blockchain via the network interface.
