Description
Technical Field
The invention relates to the technical field of computer science, in particular to a noble metal transaction and lease-integration management method for catalysis based on a block chain technology.
Background
The method for catalytically processing the noble metal refers to that the noble metal is purchased from a noble metal trading market on the first party, the noble metal is processed into a shape (net shape, granular shape, tower shape and the like) required by the third party (a manufacturer for carrying out industrial catalysis by the noble metal) by a noble metal processing factory (the second party), the first party leases the noble metal to the third party by a lease mode, and the third party pays according to the period. Once the third party is used, the precious metals are returned to the first party. And the party A evaluates whether the precious metal has defects according to the contract, and if so, the party A pays the party A according to the contract agreement. During the course of the third party's use, if the catalyst composed of noble metal is inactive, the first party provides for replacement or commissions the second party for reprocessing, to ensure that the production process of the third party can be completed as expected. Wherein in order to provide successful performance of the third party, an insurance company (the third party) is required to be entrusted with providing performance insurance to cover the first party for risk. There is a high-value logistics behavior among the first party providing the second party, the second party providing the first party, the first party and the third party, and usually the first party designates a professional logistics company (the fifth party) to provide professional logistics services, and the logistics company (the fifth party) purchases logistics risks from the third party to deal with various risks.
However, because of the inertia of the traditional development modes of various industries and the incomplete maturity of the blockchain technology, the blockchain still needs a period of time when the blockchain really takes root in landing of various suitable industries, and the blockchain technology also needs to adjust the corresponding technical architecture to adapt to the characteristics of various industries. Blockchains offer the potential for financing transactions, particularly between industry participants who know and trust each other, to simplify the transfer of ownership and guaranteed equity in lease, loan and Equipment Financing Agreements (EFAs). In a typical rental transaction, a lessor will enter into a rental agreement with a lessee through a hard copy or electronic ticketing (ECP), establishing a data link between the two parties.
If the lessor sells the contract or the amount receivable resulting therefrom, the buyer or financer is added to the chain. If financing is part of an asset support voucher (ABS) release, which is guaranteed by hundreds of multiparty contracts, ownership of the pool of contracts will be transferred to a Special Purpose Entity (SPE). The SPE will guarantee the contract bearer or mortgage agent that it has contract and accountable ownership and its rights in the device. Both these transfer and underwriting parties will be added to the chain.
In the traditional precious metal financing lease activity, because the transaction amount is large, the region involved by the customer is wide, the transaction opponents in the transaction link are more, the transaction period is long, the background information of the transaction opponents is hidden, and the management of the lease activity is completed by the mode that two leasing parties sign the lease agreement, the management mode of the lease activity has the following defects:
1. in reality, the lease parties have an extremely long period before contract signing because of asymmetric information;
2. as the transaction amount is too large and the transaction link is opaque, the financing business of the bank and the transaction of the performance insurance and the transportation insurance of the insurance company can not be achieved;
3. due to the fact that the transaction amount is too large, information is asymmetric, the transaction period is long, a newly-entered production party (third party), a newly-entered logistics company (third party) and a newly-entered processing plant (second party) cannot participate in transaction, and therefore the transaction cost is too high and the efficiency is low;
4. whether the agreement is oral or written, the execution of the agreement is not supervised by a trusted third party, and the intuition of both parties is required to be relied on, so that the accurate and complete execution of the contract is not guaranteed in the process;
5. disputes arise during rental activities and can generally only be maintained by law. However, the retention and collection of evidences by both parties are often unsatisfactory, and when disputes occur, it is more difficult to restore true phases of things;
6. for large financing rental companies, it becomes easy to move the deposit of the user, after which the user of the company may need to incur a corresponding economic loss.
Therefore, a decentralized lease management platform with functions of automatically and safely executing multiple contracts by multiple parties, monitoring by participating members and tracing transaction history is extremely important.
