Problems solved by technology
[0002] As people's consumption concepts are constantly changing with the changes of the times, it has mainly tended to be affordable, economical and diversified. Therefore, more and more people shop online and trade second-hand, but for smart phones, electrical appliances, etc. For the second-hand transaction of electronic equipment, because most of the second-hand transaction industry adopts a centralized software construction model, there are many disadvantages in the second-hand transaction industry, such as information asymmetry between buyers and sellers, lack of quality assurance of electronic equipment itself, and merchants' inability to obtain the real value of traded goods.
[0003] Although second-hand websites can use third-party inspections and seller-buyer credit ratings as a reference for transactions, the inspection results cannot fully reflect the true state of the transaction, and credit ratings are aimed at "people" rather than electronic devices themselves.
Therefore, people still cannot truly understand the maintenance records of electronic equipment, are easy to be deceived, and are not conducive to the development of second-hand transactions

The invention provides an electronic equipment maintenance information query method, a maintenance node, a management node, computer equipment and a computer readable storage medium. The method comprises the steps that the maintenance node obtains maintenance information of the electronic equipment when maintaining the electronic equipment; the maintenance node uploads the maintenance information of the electronic equipment to a block chain; and after the query party pays the query cost on the block chain and queries the maintenance information of the electronic equipment uploaded by the maintenance node, the maintenance node obtains the query cost distributed by the management node from the block chain. According to the technical scheme provided by the invention, the buyer and the seller can correctly evaluate the state of the electronic equipment as a basis for buying and selling, so that the buyer is prevented from being cheated, and the development of the second-hand transaction market is promoted.
Description
