Key Technical Components of Blockchain for V2V

Decentralization andConsensus

Decentralization eliminates a copy of the ledger. Consensus algorytms must be optimized for thee high-throut, low-latency environment of vehicular networks. Practical Byzantine Fault Tolerance (PBFT) and delegted proof-of- stake (DPoS) are common ly research d inditivets to energy- intensive proof -work.

Immutable Ledger

Once a message block is appended that e chain, it cannot be altered or deleted with out visible re- mining of contribuent blocks. This immutability contributes that event historie - such as a veirle 's recomposed position at a given time - are permanently accordided andd verifiable.

For example, a smart contract can get for acceptable mololds speed or location changes; if a received message exceeds those moltiolds (np.

Latency andScalibility

Travel at high speeds, and many safety applications require sub- 100- millisecond message latency. Traditional blockchain networks (np., Bitcoin) confirm blocks every 10 minutes - clearly unsupparable for V2V. However, lightweight blockchain procols, such as the IOTA Tangle or directed acyclic graph (DAG) structures, offer zero- fee, scalable confirmations with latency low enough for veculair use.
