Systems, apparatuses, and methods are described for determining, based on blockchain, integrity of software and/or data stored on a vehicle. A computing device associated with a vehicle may determine one or more hash values for software and/or data stored on the vehicle. The computing device may receive values from read-only memory associated with the computing device and/or values from a blockchain of a distributed ledger system. The computing device may determine the integrity of the software and/or data based on the one or more hash values, the values from the read-only memory, and/or the values from the blockchain.
