Inventory management of blockchain technology enterprises
in the express logistics instry, there are blockchain companies in China, such as Walton chain
last year, Walton chain and cargo bag (Xiamen) Technology Co., Ltd. reached a strategic cooperation to help them improve their logistics solutions through the "RFID + blockchain" technical solution of Walton chain, and link the data of cargo bag in all aspects of its logistics turnover, such as the layout of the read-write system of key nodes such as in and out of warehouse, receiving and taking goods, when the objects pass any link, All the data can be read by RFID reader, and the corresponding behavior can be transformed into data, which can be uploaded to the blockchain. Users can trace the whole process of logistics with one click
the four business scenarios that can be implemented in the real environment are suitable for the application of blockchain technology
Scene 1: Express insurance
around the insurance scene, express companies carry out commodity transportation, insurance companies provide commodity insurance, merchants provide commodity sales, sellers purchase insurance services, and the government carries out instry supervision
then, what should be recorded on the blockchain? There are several key points, such as the logistics details, accounts, identities, claims and other reference data of commodities are recorded on the blockchain
insurance is the concept of contract. When the customer signs for the package normally, the account claims will be automatically triggered, the contract will end normally, and the premium will be automatically cleared. If there is a problem or lost part, the insurance company's claim process will be triggered
Scene 2: public express
for public welfare activities, such as "one cent" activities, one cent of the cost of each public parcel is donated to the account of public welfare organizations. In this scenario, the express company still undertakes the transportation of goods, the public welfare organizations provide the implementation of public welfare activities, and the poverty alleviation businesses provide the sales of public welfare poverty alleviation goods
then what is recorded in the blockchain is the logistics details of the goods. After the package is signed, it will be recorded on the blockchain and automatically trigger the transfer from the public welfare account of the logistics company to the account of the public welfare organization. When the public welfare activities are over, the whole process is open and transparent, avoiding the public's distrust of social public welfare activities
Scene 3: share the instry blacklist
the blacklist of express delivery practitioners is still dominated by offline mode at present. We hope that through the blockchain technology, each company can record the blacklist of employees on the blockchain, and other companies can also query, and the data can not be modified, and can be traced back to the information such as which company this person did what kind of inappropriate behavior
Scene 4: Supervision of security incidents in postal delivery channels
many express companies will install security inspection machines, and the government also wants to know whether each logistics company has any potential transportation security incidents. Through the mode of Distributed Accounting, each express company can record the effective information of the security event on the blockchain when there is a security event, so that the regulatory authorities can monitor in real time and can not tamper with it

in the future, jinwowo network technology will continue to tap the value of blockchain technology in the commercial field
For blockchain messages, bitcoin is to blockchain what e-mail is to the Internet. As we all know, e-mail for the first time in the history of human information dissemination and exchange realizes the function of timely, free and verifiable sending data to anyone else in the world. Both the sender and the receiver can save copies of the data sent in e-mail. However, the e-mail data copies retained by both parties also become an inherent defect of online value transfer, because both parties have their own value. Therefore, it is necessary to ensure that the value is not double paid by the existence of third-party institutions, such as banks, stock exchanges, clearing centers or notaries. As an internet protocol, bitcoin can transfer value to each other instantly and safely without the existence of intermediary organizations such as credit granting third party, which reces transaction cost and improves transaction efficiency. Xiaobian now arranges the schematic diagram of blockchain technology and related technical principles for you
literally, blockchain is a distributed account book system composed of a series of data blocks generated by cryptographic methods. Each data block contains a large amount of transaction information, which is used to verify the validity of its information and generate the next block. These blocks are arranged in the order of generation, and each block is a node
the remarkable feature of blockchain is that there is no third-party supervision as a central server, and the transaction information in the block cannot be changed. The information contained in the block can be financial transactions or any other digital transactions, including documents. The success of the Internet business model, which has dominated the business world of human society for a long time, depends on the third-party financial institutions as credit granting institutions to process and mediate electronic transactions. The role of the third-party credit granting institutions is to verify, protect and save transaction records
However, there are still a large number of fraulent online transactions, which need to be mediated by a third party, resulting in higher transaction costs. Bitcoin, based on blockchain technology, uses encryption to prove, rather than credit a third party, so that all parties willing to trade can achieve online transactions through the Internetevery transaction can be protected by digital signature and sent to the "public key" of the receiver who uses the sender's "private key" for digital signature. The owner of bitcoin, namely cryptocurrency, needs to prove the ownership of its "private key" in order to consume and trade online. The receiving party uses the sender's "public key" to verify the digital signature on the transaction, that is, the ownership of the other party's "private key"
each transaction is broadcast to each node in the bitcoin network and recorded in the public ledger after verification. Moreover, before each transaction is recorded in the public ledger, it needs to verify its validity. Therefore, the verification node needs to ensure two things before recording each transaction: that is,
(1) consumers have the signature authentication of their encrypted electronic currency
(2) there are enough encrypted e-money in consumer accounts
Figure 1 shows the transaction process and principle based on blockchain technology

in the Internet era, computers have proposed many ways of trusted computing for a long time, that is, any blockchain technology node adopts the mole of trusted computing. Therefore, trusted computing can make it easier to upgrade and iterate technologies in distributed networks
in terms of the real name system of blockchain technology, there is a blockchain Technology Laboratory in the United States, and they have put forward many technical solutions for the real name system. For example, the current blockchain technology is point-to-point. In many countries, such as South Korea, each of them has an e-Certificate, and they need to use the real name e-Certificate for signature in the transaction. Of course, there is a simpler solution. We can store the IP address of the whole device as part of the transaction in the blockchain application
in this way, the transaction of the whole blockchain technology can realize the real name system of technology. So this is an optional real name system. We can build a real name blockchain application network or an anonymous blockchain application network
Super key is also a significant progress in the development of blockchain technology. Because it is a distributed network, how can we supervise and control it? Cryptography, we call it multi signature
we (yunbokeji) design different blockchain application networks. If it is a blockchain application network used by a bank, we can design a super key. The keys of all nodes must be combined with the super key to generate wallets
then, the super key should be in the hands of regulators or some institutions, who can have limited control over blockchain applications. For example, the data on the current blockchain application can not be deleted, so the super key actually allows the authority to modify the distributed network
so what kind of technology is blockchain:
(1) distributed decentralization,
(2) no need to trust the system,
(3) tamper proof and encryption security. I know these words separately, but what do they mean together
1. Distributed and decentralized. It's all about this on the Internet. There's no need to say more. In short, there's no need for a central server. Everyone's data is obtained from this server. Instead, the data is put on N networked devices, and everyone can download and store it
2. There is no need to trust the system. Do you believe in banks? Because the bank is recognized by the state, the blockchain realizes a trust mode without the need of a third party. It uses n devices on the Internet to store data, which can be verified by everyone. As long as more than half of the people think you're right, you're right. No one or organization can modify more than half of the content on the Internet. If you don't believe in yourself, congratulations. You are a great philosopher
3. Tamper proof and encryption security
the blockchain adopts a series of technologies, such as sha256 and ripemd160, to ensure tamper proof and encryption security. For example, 01011000111110 represents a character. The algorithm requires four bits to be shifted to the left, supplemented by zeros, four bits to the left, and four zeros to the right, How to dece the original number according to the result? Of course, this is just a simple example.
by allowing blockchains to connect to independent side chains, enterprises will find that they can create customized solutions to meet business needs.
