Blockchain foundry built into integrated circuit

An integrated circuit (IC), comprising:

• a non-transitory memory;
• a processor;
• a blockchain foundry built in the processor, wherein the blockchain foundry is configured to generate blocks of a blockchain comprising a nonce that satisfies a numerical condition, a hash of a previous block of the blockchain, a data portion of the block, and a hash determined based on the nonce, the hash of the previous block, and the data portion of the block;
• a genesis block stored in the non-transitory memory, wherein the data portion of the genesis block comprises an identity of a manufacturer of the IC, an identity of a location where the IC was manufactured, a date the IC was manufactured, and an identity of the IC and wherein the genesis block is the first block of the blockchain;
• and
• a blockchain application built in the processor that, when the processor executes,
• sends a one-time request to the blockchain foundry to build an activation block of the blockchain that is subsequent to the genesis block of the blockchain, wherein the request to build the activation block comprises micro code that is input to the IC during a process of activating the IC for use in an appliance in which the IC is embedded,
• in response to the one-time request, receives the activation block from the blockchain foundry, wherein the activation block comprises a data portion that comprises the micro code,
• stores the activation block in the non-transitory memory,
• executes the micro code,
• based on executing the micro code, sends a request to the blockchain foundry to build a first event block of the blockchain, wherein the request to build the first event block comprises information associated with a first event of the IC and comprises a hash of the activation block,
• receives the first event block from the blockchain foundry,
• stores the first event block in the non-transitory memory,
• in response to receiving the first event block, transmits a copy of the genesis block, a copy of the activation block, and a copy of the first event block to a server computer,
• after transmitting the copies of the genesis block, the activation block, and the first event block, sends a request to the blockchain foundry to build a second event block of the blockchain wherein the request to build the second event block comprises a hash of the first event block,
• receives the second event block from the blockchain foundry,
• stores the second event block in the non-transitory memory, and
• transmits a copy of the second event block to the server computer.

A method of establishing a blockchain associated with an Internet of things (IoT) device by a block foundry implemented in a trusted security zone of an integrated circuit of the IoT device, comprising:

• receiving an activation message via a radio transceiver of an IoT device from a wireless communication service provider, wherein the activation message comprises wireless communication service authentication codes and micro code;
• in response to the IoT device receiving activation information, building an activation block of a blockchain by a block foundry implemented in a trusted security zone (TSZ) of an integrated circuit (IC) of the IoT device, wherein the activation block comprises a hash of a genesis block of the block chain stored in a non-trusted portion of memory of the IC and a data portion that comprises the micro code;
• providing the activation block of the blockchain by the block foundry to a blockchain application executing in a rich execution environment (REE) of the IC;
• storing the activation block by the blockchain application in the non-trusted portion of the memory of the IC;
• and
• transmitting a copy of the genesis block and a copy of the activation block by the blockchain application via the radio transceiver to the wireless communication service provider, whereby the blockchain is established by the block foundry implemented in the TSZ of the IC.
