  The blockchain is a safe, reliable and innovative mechanism for managing
numerous vehicles seeking connectivity. However, following the principles of
the blockchain, the number of transactions required to update ledgers pose
serious issues for vehicles as these may consume the maximum available energy.
To resolve this, an efficient model is presented in this letter which is
capable of handling the energy demands of the blockchain-enabled Internet of
Vehicles (IoV) by optimally controlling the number of transactions through
distributed clustering. Numerical results suggest that the proposed approach is
40.16% better in terms of energy conservation and 82.06% better in terms of the
number of transactions required to share the entire blockchain-data compared
with the traditional blockchain.
