1. Nature Special Distributed Database , mainly used for storing information, any information can be read and written in the block chain. 2. Features The block chain has no administrator and is not centralized, and its design goal is to prevent the emergence of a central authority. 3. Block Block chain consists of blo

One, synchronized synchronous statement block: Before introducing the synchronization statement block, do an experiment to verify that the order in which multiple threads call the same synchronization method is random. Example one: 1) Mylist.java 2) Test: It is visible that the code in the synchronization method is printed synchronously, but thread A and thread B are executed asynchronously, which may cau

Display: inline; inline elements are displayed in the same line.Display: block; block-level elements. In short, there is a line break that will be switched to the second line.Display: inline-block, which is a block-level element in the same row.The concept is too vague. Let's use a real case.A is a row by default, so i

What is a smart contractAn intelligent contract is a set of commitments in digital form (promises), including agreements in which contract participants can implement these commitments. A contract consists of a set of code (a function of the contract) and data (the state of the contract) and runs on the etheric square virtual machine. The Ethernet square virtual machine (EVM), which uses a 256-bit-length machine code, is a stack based virtual machine for the implementation of the etheric Square I

The development of the block chain is actually the history of the development of data records, today we will talk about the history of data recording development, a glimpse of this spiraling trend Data is a symbolic representation of an objective thing, an unprocessed raw material used to represent an objective thing, such as graphic symbols, numbers, letters, and so on. Or, data is the fact and concept of physical observation, a description of place

According to the three-party circulation platform forecast, by 2022, the global block chain market size will reach 13.96 billion U.S. dollars. In 2017-2022, the market grew at an annual compound rate of 42.8%. The report argues that in the financial sector, the application of block chain technology is expanding, mainly including financial transactions and cross-border payments. At the same time, the int

As the connection foundation between reality and Virtual world, IoT has been paid close attention to. Whether it is artificial intelligence revolution or block chain technology, the Internet of things will be the underlying architecture, providing valuable, available digital resources, but up to now, the internet of things still faces too many problems to be solved. The first is the problem of fragmentation. From the day the Internet of things was bo

Display: block indicates that an element is displayed as a block-level element. The block element has the following features:Always starts on a new line;Height, row height, and top and bottom margins can be controlled;The default width is 100% of its container, unless a width is set. Display: inline is to display the element as a row element. The Inline element f
