        abstract = {Vehicular Ad Hoc Networks (VANETs) enable intelligent transportation systems through real-time vehicle-to-vehicle and vehicle-to-infrastructure communication. However, high mobility, frequent topology changes, and open wireless channels expose VANETs to routing failures and security attacks, while routing-based dissemination introduces latency unsuitable for safety-critical applications. This paper proposes a blockchain-enabled, context-aware secure routing framework augmented with peer-to-peer (P2P) safety beacon communication for real-time accident prevention. A lightweight permissioned blockchain deployed at roadside units manages trust and identity, directly influencing routing decisions via a routing fitness function. For ultra-low latency safety use cases, vehicles periodically broadcast compact safety beacons and employ Time-to-Collision (TTC) prediction to trigger early warnings. The framework is implemented and evaluated using NS-3 for secure routing and SUMO–OMNeT++ (Veins) for accident scenarios. Results demonstrate improvements in packet delivery ratio, delay, throughput, attack mitigation, and sub-100 ms safety alert latency compared to routing-based approaches.},
