Why you want to learn blockchain technology development. Before you answer this question, you need to point out: Blockchain is now an over-valued area, and these overvalued values are unsustainable and will certainly collapse. Such bubbles have occurred before and may occur again. But if you work in this field for a long time, you will learn to get rid of the effects of bubbles. In the words of Emin Gun Sir

Preface Blockchain development is really fast this year. From the first unfamiliar concept, to now has started in various industries, a spark of great prairie fire. I wish I could have my own blockchain practice practiced hand O (∩_∩) o~. But a person, a computer, how to set up the blockchain environment ... It's not easy to say you love a block chain of fire.

Blockchain is the underlying technology and infrastructure of Bitcoin, essentially a de-centralized database. A blockchain is a series of data blocks that are associated with a cryptographic method, each of which contains information about a bitcoin network transaction that verifies the validity of its information (anti-counterfeiting) and generates the next chunk.In the narrow sense,

Blockchain technology is now very hot, not only for financiers and venture capital to flock to, and now has been sown in many fields everywhere. As an entrepreneur with sharp tentacles, do you want to integrate blockchain into your existing applications, and as an IT technical engineer, are you eager to practice a hand based on blockchain to avoid being eliminate

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

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

The basic concept of blockchain is simple: a distributed database that stores an ever-growing list,list contains many sequential records. The following article mainly introduces you to the Python learning of the blockchain of the relevant information, the text through the sample code introduced in very detailed, the needs of the friends below to see together. Objective This article will give you a brief in

In the previous article, we constructed a very simple data structure, which is also the core of the entire

In layman's words, a blockchain is a general ledger that includes all the historical transactions, and each chunk contains several transactions. If the blockchain is a ledger, then chunks are every page of the ledger. The details of the transaction are recorded on a public ledger that can be seen by anyone on a network. A chunk is a collection of many transaction data, Fang Hua a
