Blockchain Enthusiast (qq:53016353) Through the methods described in this article and the script, we can quickly set up their own private chain for blockchain development testing, this article is based on the Ethereum technology to build, divided into two parts, one is the Ubuntu under the construction method, the other is the Windwos under the building method, about the basic knowledge of ethereum related,

Most people do not need to re-create a set of blockchain, but based on the existing blockchain underlying platform to develop their own applications, for similar encryption algorithms, peer-to technology, consensus algorithm and so on only need to have a basic understanding can be, temporarily do not need in-depth research. In the text, there are three main blockchain underlying platforms: Bitcoin, Ethereum, and Super Ledger fabric, as well as the app

Blockchain Enthusiast (qq:53016353) Through the methods described in this article and the script in the project, we can quickly set up their own private chain for development testing. The tools included in the warehouse are: A Test Account import script that imports five test account private keys into the Ethereum node at first deployment.A Genesis.json configuration file that provides initial funding (etheric currency) for the corresponding five tes

is Ethereum (Ethereum). Ethereum (Ethereum) is a Turing complete blockchain one-stop development platform that implements protocols in a variety of programming languages and uses the Go language client as the default client. It allows anyone to build and use distributed applications that run through blockchain technol

Recently in the research block chain. Plan to build a test environment to start running. The whole construction process is recorded here for up-and reference. Overall, it is divided into three steps to install the relevant software, initialize the system, set up the cluster, and the last step to dig the mine. We are using the ether, compared to other blocks of the chain, which is a mature environment. Although the recent hard branch of the event, for enterprise applications, the function is stil

Blockchain Enthusiast (qq:53016353) 1, the same language of the client on different platforms use is exactly the same 2, different languages of the client (mist, Geth, ETH, etc.) between the same platform (Linux, Windows or OSX) share the same application configuration, and its command line can use the same parameters. The following is a breakdown of the purpose and characteristics of each client using the project on GitHub: First, Go-ethereum proje

, after two ups and downs, reached a dazzling climax. In the end, the wonderful ending tells us that their conversation is almost an inevitable fate. In the middle of the 17th century, it was the last darkness before the dawn of science. No one could predict that these two sparks would soon trigger a raging fire. * ******* After dinner, let's talk about "Aether ). As we have seen above, ethereum was initially proposed as a light-wave media assumption.

1. Installing the Geth Client Enter the command: sudo add-apt-repository-y ppa:ethereum/ethereum#启动PPA储存库 sudo apt-get update#访问源列表里的每个网址, and read the software list and then save it to your computer sudo apt-get install Ethereum#安装Go Ethereum 2. Check after installation is complete Using commands Geth versionTo check if the installation was successful

the nodes are beginning to upgrade to the new version, then the old node maintenance chain can survive depends on how much power, this is called a hard fork. Obviously, the most superficial understanding is the soft fork or a chain, the hard fork will be divided into two chains. There are over-forks in Ethereum and Bitcoin, and what are the pros and cons of soft forks and hard forks in practical applications for real-world applications: The soft fork

Click on the "Blue word" above to follow us. Author: Christopher Tozzi Translator: Pencil case If your technology doesn't scale, it probably doesn't have any meaning at all. At least, in the real world there is no use in any sense. Blockchain-based media is no exception. In order to be able to apply in the media domain, blockchain technology must be scaled up to accommodate and increase user and demand. Bitcoin-based media blockchain is facing a huge challenge. Traditionally, Bitcoin has n

the globalization has been running for many years in a stable. Bitcoin transactions between any two accounts are faithfully recorded on a large number of redundant ledgers. In a bitcoin network, any account is anonymous, and any transactions between accounts are non-tamper-proof and are recorded on each node. Then through to the mining of bitcoin incentive mechanism to achieve the self-operation of this network, without any centralized trading system. Aether Square So what is

Through the above operations, the basic can be counted on the block chain has a preliminary understanding and perception. three, the ether square each project explanation After the launch of the ether, there are many clients, but also support a number of platforms, beginners are often confused by a variety of clients, this article carried out a detailed summary. Ethernet Square Client Language classification, in the GitHub divided into different projects, source code address: https://g
