System of security using blockchain protocol

A transmission system which comprises:

• a plurality of network devices, wherein each network device comprises a network participating device, and wherein each network device includes at least a processor and memory by which each network device communicates data record structures between the network devices;
• the transmission system programmed to:
• transmit the data record structures over a network of the network participating devices, wherein the network of the network participating devices operates as a Blockchain that comprises a plurality of ledgers held on a plurality of said network participating devices, wherein each ledger comprises said data record structures;
• the network participating devices programmed to:
• communicate contents of the ledgers between them over the network and verify the contents of the ledgers;
• generate, by an initiating device of the network participating devices, an initial data record structure wherein, the initiating device has an initiating device has an initiating device unique identifier and the initial data record structure contains at least a first record comprising:
• a token;
• and
• the initiating device unique identifier;
• transmit, by the initiating device, the initial data record structure over the network to a first receiving device of the network participating devices, wherein the first receiving device has a first receiving device unique identifier
• test, by the first receiving device, the integrity and identity of the initiating device by performing the following:
• compare the initiating device unique identifier contained in the first record with the initiating device unique identifier;
• and
• determine that the initiating device is trustworthy based on the comparison showing that the initiating device unique identifier contained in the first record matches the initiating device unique identifier;
• accept the token, by the first receiving device, based on the determination that the initiating device is trustworthy;
• generate, by the first receiving device, an additional data record structure that contains at least a second record comprising:
• the token, and
• the first receiving device unique identifier;
• transmit by the first receiving device, the additional data record structure to a second receiving device of the network participating devices that has not yet received the token;
• test, by the second receiving device, the integrity and identity of the initiating device by performing the following:
• compare the first receiving device unique identifier contained in the second record with the first receiving device unique identifier;
• determine that the first receiving device is trustworthy based on the comparison showing that the first receiving device unique identifier contained in the second record matches the first receiving device unique identifier;
• accept the token, by the second receiving device, based on the determination that the first receiving device is trustworthy, wherein the token is transmitted from network participating device to network participating device on the network on a rotating basis to ensure that every network participating device receives the token over a predetermined period of time thereby to test the integrity/identity of each network participating device on the network that is participating in the Blockchain.
