Permissioned distributed ledgers (PDLs) provide
security and trust for Internet of Vehicles (IoV) applications,
but face scalability issues due to resource-intensive consensus
mechanisms. To address this, we propose a novel hybrid con-
sensus network (HCN) architecture that leverages the compu-
tational capabilities of parked connected autonomous vehicles
(CAVs) through a multi-layer vehicular edge computing (VEC)
framework. The HCN is designed following guidelines outlined
by the European Telecommunications Standards Institute (ETSI)
regarding the structuring of PDLs. It aims to improve the per-
formance, reliability and scalability of PDL-based IoV networks
while maintaining their security and trust guarantees.
