Optionally, the following business operations are executed at the egress operation end:
when the paper insurance letter is adopted, the uploaded photocopy of the paper insurance letter is received and compared with the pre-stored insurance letter data.
Receiving the photocopy uploaded by the voided slip sheet to mark voiding.
It should be noted that the step 302 is responsible for chaining the related bills to form a continuous blockchain node and linking to the previous node (block) to become data that is not tampered on the chain during the process of performing the steps 300 and 301.
Therefore, by establishing a block chain network among domestic agents, overseas agents and shippers, with the help of a consensus algorithm and a billing mechanism of the block chain and the characteristics of a block chain distributed account book, key operations such as bill submission, release inspection, release completion and the like can be immediately synchronized among nodes of the block chain after completion, so that the time-dependent change of the mail mode of the bill submission is compared with that of the original bill submission, the E-mail sending mode of the bill submission is also remarkably improved compared with that of an E-mail sending mode of an E-mail release bill, the bill submission operation and the information sharing are more convenient and smooth, and the user experience is remarkably improved.
In fig. 3, the exporter bank, importer bank, insurance, etc. can also be included in the block chain alliance to support the payment of freight, insurance, payment, etc. fees; or the bill of lading is issued and directly stored in nodes of an internet court and a notarization department, so that the court is convenient to obtain the evidence.
Furthermore, the bill carrying system is unified, and the safety and credibility of data such as bill carrying content, goods and document states, bill carrying flow records and the like are guaranteed. The functions of safety, dispersed storage, flexible preview and the like of the bill of lading can be realized through the block chain technology. The security of the bill of lading means that the transmission of the block chain electronic bill of lading depends on Public Key Infrastructure (PKI). Only the actual owner of the private key can initiate transfer to the other party. The decentralized storage of bills of lading means that they cannot be changed unintentionally or maliciously for whatever reason. The bill picking preview means that any party receiving the block chain electronic bill picking (or similar transportation documents) in the business process of the bill picking management platform based on the block chain can preview the file before receiving the bill picking.
As shown in FIG. 3, the summary federation chain is
