The vast enhancement in the development of Internet Vehicles (IoV) is due to impact distributed emerging technology and topology industrial IoV. It has created a new paradigm, such as security-related resource constraints Industry 5.0. A revolution dimension IoV popup raise various critical challenges existing information preservation, especially node transactions communication, transmission, trust privacy, security-protection-related problems, which have been analyzed. These aspects pose serious problems for industry provide vehicular-related data integrity, availability, exchange reliability, provenance, trustworthiness overall activities service delivery prospects against increasing number multiple transactions. In addition, there lot research interest that intersects with blockchain association. this regard, inadequate performance connected nodes high requirements consortium ledger not yet tackled complete solution. introduction NuCypher Re-encryption infrastructure, hashing tree allocation, proof-of-work require more computational power well. This paper contributes two different folds. First, it proposes sawtooth-enabled modular architecture protected, secure, trusted execution, delivery, acknowledgment immutable storage security peer-to-peer (P2P) network on-chain off-chain inter-communication vehicular activities. Secondly, we design create smart contract-enabled structure order smooth streamlined broadcast content. Substantially, develop deploy hyperledger sawtooth-aware customized consensus investigations. For validation purposes, simulate related details between devices on simulation results show proposed BIoV reduces cost down 37.21% robust generation up 56.33%. Therefore, only 41.93% 47.31% Vehicles-related resources are kept used, respectively.
