<p style="text-align:justify">Lately, the blockchain-based car edge computing (VEC) community permits the computation activity of vehicular networks to be offloaded to a number of distributed edge computing nodes deployed in roadside models (RSU), whereas realizing dependable and decentralized info sharing amongst RSUs. Within the subsequent technology of vehicular networks, the computing and storage capability of automobiles shall be improved. Subsequently, it's extremely possible to deploy blockchain nodes to automobiles and RSUs on the similar time. Nevertheless, there are apparent variations between car nodes and RSU nodes when it comes to mobility and communication protection. The communication mode between automobiles and RSUs will have an effect on the precise mode of block propagation, which wants additional exploration. As well as, the consensus mechanism adopted by the prevailing blockchain-based VEC can not totally exert the communication capacity of all nodes, leading to low consensus effectivity, which must be improved.</p>
<p style="text-align:justify">To review the enhancements within the consensus course of when blockchain nodes are deployed on automobiles and RSUs, this paper analysis the dynamic technique of block propagating between RSUs and automobiles. Aimed on the implementation of blockchain nodes, a reputation-based consensus mechanism is proposed as properly. By evaluating the numerical and simulation outcomes, the feasibility of the proposed consensus mechanism is verified.</p>
<p style="text-align:justify">The primary contributions of the paper are as follows:</p>
<ol> <li style="text-align:justify">The dynamic technique of block propagating between automobiles and RSUs is analyzed.</li> <li style="text-align:justify">The dynamic equations of the single-block propagation for 2 particular situations are introduced and additional mentioned. The dynamic state transitions of automobiles within the multiblock propagation are illustrated.</li> <li style="text-align:justify">We design a reputation-based consensus mechanism, which separates the consensus course of between RSUs and automobiles and requires all nodes to take part within the forwarding technique of the brand new block.</li> </ol>
<p style="text-align:justify">The dynamic equations and consensus mechanism proposed within the paper are analyzed and simulated in a 12km×12km sq. area the place 0∼50 RSU nodes and 200 car nodes are contained. RSU nodes are evenly distributed within the area, whereas the actions of car nodes comply with the random path mobility mannequin.</p>
<p style="text-align:justify">The outcomes confirmed that the block propagation time decreases because the variety of RSU will increase, and the proposed reputation-based consensus mechanism significantly reduces the consensus time. By deriving the dynamic equations of a single-block and multi-block propagation course of, we outlined multi-block propagation as a blockchain forking aggressive propagation.</p>
