. All that is needed is to roll up your sleeves and join the battlefield. No.4 demand for blockchain developers far exceeds supply There are not enough developers in this area, and it is not possible to get training quickly. Everyone is competing to hire blockchain technicians, and the project isFeeling the pressure of talent shortage. Many of the best companies are unable to pay enough to retain staff beca

Click on the "Blue word" above to follow us. Author: Bernard Marr translation: Ina Another transformative new application of blockchain technology can have a broad impact on how employers assess candidates and recruit employees. Blockchain is basically a way to record information on a distributed cryptographic ledger-eliminating the trust or middleman of a third party in many applications. Today, it

Understanding the concept of blockchain is simple (block chain, trading chain block): It is distributed (ie not placed on the same machine, different network devices on the) database to support the hosting record of the growing list. However, it is also easy to confuse blockchain with the idea that we are trying to help him solve the goal--at that moment in people's minds, the word is pretty strong about tr

, companies have no time to wait for college graduates to fill this demand. They need help now, so many people are turning to the so-called "new job", a term that refers to working-class workers who do not need a college degree but need to attend training. This approach is a desperate practice for major companies to combine traditional college recruiting and cooperative education. In a September report, MSNBC highlighted this growing group of people trained to work on specific

However, the actual situation shows th

We all know that it is very difficult to calculate the seal number. A

The super ledger fabric is based on the Go language implementation, and local compilation is recommended to configure Golang1.7 or later environments. Here's how to compile a binary file that generates components such as Fabric-peer, Fabric-

Write the first Java chain code programIn the previous section, you are already familiar with how to build, run, deploy, and invoke chain code, but have not yet written any Java code.In this section, you will use the Eclipse IDE, a Gradle plug-in for Eclipse, and a Java chain Code framework project called Chaincodetutorial to write the first Java chain Code program. You'll get the skeleton code from the GitHub repository I created for this tutorial, import that code into Eclipse, add code to mak

interacts with the fabric. The function uses the Shim interface function Getstatebyrange to return the ledger data between Startkey and EndKey args. These keys are defined as CAR0 and CAR999, respectively. Therefore, we can theoretically create 1,000 cars (assuming the keys are correctly labeled), and a queryallcars will show each one. The lower half of this method is converted back into JSON format. Here is a schematic diagram of the application c

Events Original On the May 16, someone wrote the signature of the virus dos/stoned into the digital currency block chain. Because this is just the signature of the virus, not the code of the virus, it does not actually pose any danger to the user. However, for Windows to add an EXE suffix as a system to execute the file, it is very important to prevent the awareness of hardship. So when the Microsoft Antivirus Suite (MSE) found the signature of the virus, a tragedy began: The MSE began to r
