Blockchain logistics training platform

1. In many cases of blockchain commercial application, we can always see the word baas. Baas is the abbreviation of blockchain as a service, which is translated into "blockchain as a service" in Chinese. So what is blockchain as a service baas? With this question, we will follow Xiao Wang of Renren blockchain technology team to discuss it carefully
according to Xiao Wang, the concept of blockchain as a service (baas) is mainly proposed by Microsoft and IBM. To put it bluntly, it is actually a new type of cloud service, a cloud service combined with blockchain technology. For example, Microsoft's azure cloud computing platform and IBM's bluemix garage cloud platform all provide blockchain as a service baas
blockchain as a service (baas) is a space created by enterprises such as Microsoft and IBM from their own cloud service network to run a blockchain node. Compared with ordinary nodes and exchange nodes, the main purpose of baas nodes is to quickly establish the development environment they need, and provide a series of operation services based on blockchain, such as search query, transaction submission, data analysis, etc. these services can be centralized or decentralized to help developers verify their concepts and models faster. The service of baas node is reflected in: it is more instrumental and easy to create, deploy, run and monitor blockchain.

Blockchain platforms include Ethereum, Asch and other underlying application development platforms

Ethereum, an open source public blockchain platform with smart contract function, provides decentralized Ethereum virtual machine to process point-to-point contract through its special cryptocurrency ether (ETH)

arch, a decentralized application platform based on side chain technology. Asch is designed to lower the threshold of developers, such as using JavaScript as the application programming language and supporting relational database to store transaction data, which is believed to be very attractive to developers and small and medium-sized enterprises

extended data

in 2008, Nakamoto first proposed the concept of blockchain. In the following years, blockchain has become the core component of electronic currency bitcoin: public account book for all transactions

by using peer-to-peer network and distributed timestamp server, the blockchain database can be managed independently. The blockchain invented for bitcoin makes it the first digital currency to solve the problem of repeated consumption. Bitcoin's design is a source of inspiration for other applications

bitcoin is the absolute mainstream of digital currency, and digital currency is in full bloom. Bitcoin, litecoin, dogecoin, dashcoin are common. In addition to currency application, there are various derivative applications, such as Ethereum, Asch and other underlying application development platforms, as well as NXT, SIA, bitstocks, maidsafe, ripple and other instrial applications

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

the contents of this article do not constitute any investment suggestions. There are risks in the market and investment should be cautious

4. The application of blockchain and logistics supply chain is now in the landing state, and the blockchain + mode is very popular. Changsha Information Instry Park has built a service platform project of SMIC blockchain, which is for enterprises to collect information on the chain, and to build a blockchain instry alliance.

5. At present, there are indeed many companies doing IOT blockchain. Although many large companies have not officially publicized it to the outside world, Oracle, Samsung, sap, Amazon, Google, Microsoft, IBM, apple, Internet, Alibaba, Tencent and Jingdong are basically involved in R & D and exploration in the field of IOT blockchain. At present, vertical IOT blockchain companies are relatively low-key, At present, I have met a company called chaincomp chain computing. If there are other similar companies, you are welcome to supplement and exchange.

6. Blockchain course resources are more authoritative

7. The existing conditions can't handle such a large-scale liquidation, but with the blockchain system, the confirmation of the right of each transaction is fixed. The liquidation only needs to be carried out according to the existing results, and there is no need for review. A lot of manpower and material resources are saved in the process, and the speed of liquidation will certainly be greatly increased, which is determined by the non tamperable characteristics of the blockchain, For example, Nanjing Rongze has a similar block chain inclusive financial platform.

8. The technology of blockchain should belong to the bottom, which is rather difficult. That day, it was reported that it is difficult to recruit people with an annual salary of 30 million yuan. The dark horse programmer has studied for more than two years and developed a set of courses, which will be opened in Shenzhen in the near future.
