Classification: CPC G  H | IPC G  H

Claim 9:
10. A device operating as a node in a blockchain system that includes an issuer node, wherein the node is part of a peer-to-peer network configured to store at least a portion of a ledger of the blockchain, and configured to maintain up-to-date approved component characteristics in the portion of the ledger through cryptographic communication with other nodes of the peer-to-peer network, the device comprising:
means for detecting an installation of a component for a vehicle;
means for determining, in response to detecting the installation of the component, an operating characteristic of the component based on measurements captured by one or more sensors installed in the vehicle while the vehicle is operating;
means for monitoring an engine of the vehicle;
means for determining, while the component is in operation and for each of a plurality of different revolutions per minute of the engine, a respective measurement of the operating characteristic; and
means for comparing a combination of each revolutions per minute of the plurality of different revolutions per minute and the respective measurement of the operating characteristic to approved combinations of the operating characteristic at different revolutions per minute stored in the approved component characteristics in the portion of the ledger of the blockchain for a corresponding component type;
means for determining, based at least in part on the comparison, that the component is an approved component for the vehicle, wherein the issuer node is configured to add, to a most recent block of the blockchain, an up-to-date version of an approved operating characteristic in response to an update by an original equipment manufacturer of the vehicle, wherein to add the up-to-date version of the approved operating characteristic the issuer node is configured to create a hash block by applying a hash function to an existing block in the blockchain and append the up-to-date operating characteristic to the hash block to create the most recent block of the blockchain; and
means for outputting based on the determination that the component is the approved component for the vehicle, a notification to a display device of the vehicle.
