Description
Technical Field
The invention relates to the technical field of block chains, in particular to a 3C (third-generation) commodity leasing method and system based on a block chain and an IPFS (Internet protocol file system) technology.
Background
The 3C is a substitute for three household electrical appliances, namely, computers and their peripheral communication (Communications, most likely mobile phones) and Consumer Electronics (Consumer-Electronics). At present, 3C leasing industry is promoted by depending on brands and public praise, and as the loss layer of 3C product equipment is infinite, including visual loss, all details are difficult to ensure by simply using a paper contract, a lessor and a personal lessee generate disputes on the description of leasing in the 3C leasing industry, and each party holds a word to cause various business disputes. Since the internet industry is influenced by the evaluation of each user to some extent, the real situation behind the score is difficult to distinguish for other people, and the 3C leasing company can finally commit the score and complete the score and comment even if the responsibility is not in the company, so that the company brand is maintained by bearing the loss on the company.
Some enterprise renting users in the industry can collect photos before renting, but the photos can be changed and can be repaired by PS (photo service), so that the photos lack of uniqueness certification and lack of effectiveness in law; and each case needs to wait for the court to distinguish whether the picture is true or false, thereby greatly wasting legal resources. In addition, the rental equipment is often lost or changed, liability cannot be determined after damage, two parties tear skins and the like, so that the rental enterprises cannot be effectively protected, rights and interests of tenants cannot be reasonably guaranteed, and 3C rental industry development is limited to a great extent. There is a lack in the industry of a third party notary system to provide a reliable channel for the certification, circulation and documentation of each item, with the details of each device or unchangeable unique, legal notations.
