A secure chain of data blocks is maintained at a given computing node, wherein the given computing node is part of a set of computing nodes in a distributed network of computing nodes, and wherein each of the set of computing nodes maintains the secure chain of data blocks. The secure chain of data blocks maintained at each computing node comprises one or more data blocks that respectively represent one or more transactions associated with a vehicle. At least one data block is added to the secure chain of data blocks maintained at the given computing node in response to determining that transaction data associated with the at least one data block is valid.
