A system and method providing Proof of Location or Proof of Location and Velocity consensus in a blockchain network using radio frequency (RF) signals. Nodes validate the location of other nodes in the network using PING-PONG round trip signal propagation time to determine maximum distances to other nodes. These maximum distances are then shared between nodes, whereupon the nodes use computational techniques to resolve validated, geospatial location of the other nodes. The sharing of measured maximum distances to local nodes is a form of Proof of Location consensus. The validated geospatial locations (and velocities) of local nodes are then written to the blockchain, creating a time history for each node. This information may be used by the blockchain operating rules to implement any number of security and other operational functions. The ability of the invention to operate without need for time synchronization between nodes is an advantage of the system.

Systems and methods for blockchain-based asset authentication are described. The disclosed embodiments leverage the traceability and immutability of blockchains (or distributed ledgers, in general) to enable the authentication and ownership of assets, e.g., luxury goods. In an example, this is achieved by first pairing an authentication chip with a physical product, and writing a transaction correlated with the first pairing to a blockchain. The product being acquired (reacquired) results in the blockchain being updated (e.g., an updated transaction being written to the blockchain) and the (subsequent) owner being provided with a digital passport that can be added to the owner's digital Web3 wallet. The described embodiments advantageously enable digital identities to be associated with physical goods, which adds value for customers making a long-term investment in a luxury good, and promotes sustainability and transparency in manufacturing and retail processes.
