The basic concept of blockchain is simple: a distributed database stores an ever-increasing list, which contains many ordered records. However, when talking about blockchain, we often talk about the problems solved by using
Now we have read the technical logic of many overseas blockchain projects. In fact, there are also a lot of domestic high-quality blockchain projects, and the momentum is very strong, so it cannot be underestimated.
I introduced several domestic blockchain projects in the previous article, but I gave a brief overview from the perspective of development and did no

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

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,
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

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.

what the blockchain is.
"Blockchain" technology was originally designed by an alias Satoshi for Bitcoin (a digital currency) and a special database technology, it is based on the cryptographic Elliptic Curve Digital Signature Algorithm (ECDSA) to achieve the central to the design of the peer system. But the role of the
verification speed of the blockchain. No need to worry about transactional issues, just care about the output script. Utxo cannot be split, each transaction requires multiple outputs, respectively, for expenses and change. The advantage of the account model is the ability to quickly get the balance of an account, and Bitcoin needs to integrate the total amount of unused transactions in all Utxo owned by the specified address. Save space because there
