Proof of location and velocity blockchain consensus mechanism system and method

A system for validating a node in a blockchain network, using Proof of Location (POL), comprising:

• a blockchain network comprising a plurality of nodes, at least a portion of the nodes being in RF communication with one another, at lease some of the nodes operating as validating nodes, and at least some of the nodes operating as proposing nodes desiring to be validated;
• wherein each of said nodes is also in data communication with one another for the purpose of communicating blockchain messages;
• and
• wherein each of said nodes comprises a processor in communication with a non-transitory memory, a local time base for determining local time to a desired precision, and a transceiver;
• wherein each of said nodes contains a copy of a blockchain ledger in memory;
• and
• wherein said memory of each of said nodes contains computer readable and executable instructions for 1) executing blockchain transactions;
• and 2) to assemble and transmit a PING signal able to be received by said at least one local node, receive a PONG signal from said at least one local node on the network, transmit an ECHO signal to the said at other local nodes on the network, to communicate with the other nodes on the blockchain network for the purpose of communicating blockchain messages, and carry out steps for validating a node, comprising:
• aa) determining, by each local node operating as a validating node (“validating node”), a lightsphere for each of the other local nodes operating as a proposing node (“proposing node”), said lightsphere representing a maximum distance from each node operating as a validating node to each other local node operating as a proposing node;
• bb) communicating, by each local node operating as a validating node to each other local node, the lightsphere for each other node operating as a proposing node;
• cc) determining, by each node operating as a validating node, a geospatial position for each node operating as a proposing node, by performing computations on the lightsphere information for each node operating as a proposing node provided by each node operating as a validating node;
• dd) determining, for each node operating as a proposing node, whether such node's geospatial position may be determined within a predetermined margin of error;
• ee) declaring, by each node operating as a validating node, that each node operating as a proposing node is validated if the geospatial position for such other local node falls within the predetermined margin of error.

A method for determining the authenticity of a proposing node in a blockchain network comprising one or more validating node(s) by determining the geospatial relative velocity of the proposing node, by measuring the doppler effect shift of a PONG from the proposing node, the method comprising the steps of:

• oo) determining, by each node, its own geospatial position and velocity vector in a three-dimensional frame of reference;
• pp) determining, by each of the one or more validating node(s), the relative velocity to the proposing node that is within radio communication range using a PING-PONG approach;
• qq) determining, by each node, a maximum distance to the proposing node, with no additional information or radio broadcasts other than the PING-PONG method;
• rr) transmitting, by each validating node, an RF signal that is receivable by its local nodes, wherein said RF signal being an Echo also containing velocity information for the proposing node;
• ss) applying computational techniques onboard or offboard each validating node to determine the geospatial position and relative velocity of the proposing node;
• tt) declaring the proposing node as validated in the case in which the proposing node's geospatial position and velocity are within a pre-determined margin of error;
• uu) repeating, steps oo)-tt) over time, with the result that a time history of verified geospatial velocity information for each validated node is written to the blockchain.
