Description
Technical Field
The invention relates to automobile leasing, in particular to an automobile leasing method based on a block chain.
Background
At present, the automobile leasing market at home and abroad is huge, and particularly, the demand for automobile leasing is urgent in the first-line city of wide and deep north.
The blockchain technology is a chained data structure based on a timestamp, can be guaranteed to be not tampered in a cryptographic mode, is a decentralized and distrusted distributed shared general ledger technology, all nodes participate in data backup and maintenance together, and data stored in the blockchain cannot be affected due to the fact that one node is tampered or damaged, so that safe storage of the data is achieved. Distributed node verification and communication are realized through a P2P network technology and a consensus mechanism, a trust relationship is established, a complex business logic function is realized through an intelligent contract, and the transaction is automatically operated.
The existing automobile leasing scheme comprises the following two types:
A. the tenant releases car renting information on the internet platform, wherein the car renting information comprises 58 city-sharing information, catch-up network information and the like, and a car owner releases car information on the internet platform;
B. the tenant leases the car by contacting a mediation company that provides the car autonomously.
Both of the above two car rental modes have certain problems: for the first mode, in order to save time and energy, a vehicle owner mostly sends vehicles to an intermediary, and entrusts the intermediary to rent the vehicle, so that most of the vehicle information on the platform is issued by the intermediary, and a tenant is difficult to determine the authenticity of the platform for issuing the vehicle information; for the second mode, the intermediary company that provides the vehicle autonomously has a limited development because it has a small number of vehicles.
In addition, the two internet automobile leasing modes have common problems: the issue of trust of the two parties to each other is leased. Because the rental behavior is usually one-time activity, both the car owner and the tenant do not know each other, in order to ensure that the car is not damaged after being rented and traffic violation behaviors are not generated, the car owner generally collects extra fees as security deposits before renting; after the tenants complete the lease, the tenants can worry about the dishonest of the car owners, and the security deposit is withheld for various reasons. This potential trust crisis is a significant barrier to the development of the current automobile rental industry.
