hyperledger sawtooth

Since my boss suddenly gave me an IBM Blockchain course website, I taught myself to finish two lessons from the blockchain provided by IBM and complete the compose-playground of this blockchain component in the fabric framework. This stand-alone construction is relatively simple, IBM's course has after-school this component related exercises and the document, therefore spent 2 days or so completed. Then the boss let me build a multi-machine cluster fabric, and then toss about half a month to fin

Super Record Book: Quickly build a Hyperledger Fabric 1.0 environment Here we start our environmental set-up work: 1. Use VirtualBox and install Ubuntu in it This step is actually nothing to say, download the latest version of VirtualBox, download ubuntu server, I use the Ubuntu16.04.2 X64 server. After installing Ubuntu, you need to ensure that apt source is domestic, otherwise it will be slow and slow if it is abroad. The specific approach is

Introduction of Hyperledger Project Hyperledger Project is an open source, collaborative program designed to create block chains for business-to-business and business transactions. IBM is one of the founding members of Hyperledger project, contributing 44,000 lines of block chain code to the Hyperledger Fabric of the f

AA (anti-aliasing) anti-aliasing many players may often encounter in the game's image quality settings. In other words, AA is a little more popular: mixing the image edge and the pixel colors on both sides, then, replace the original position with the newly generated point with a mixed property...

Anti-aliasing: translated as "anti-image folding distortion". Because in 3D images,Resolution Constraints,The edges of an object always show more or less the serticate of a triangle, while anti-serticate means to soften the edge of the image so that the edge of the image looks smoother and closer to the object.. It is a way to soften the image quality. The latest full-screen anti-sawtooth (fullsceneanti-aliasing) can effectively eliminate the dislocat

Hyperledger Fabric's environment on Ubuntu First install Ubuntu on the VMware Workstation virtual machine, configure the environment, adjust the Chinese language, the resolution, open the terminal. PS: After installing Ubuntu system if you find that files with Windows system can not replicate with each other, the web looked up a lot of tutorials, found that are not available, the method can be implemented as follows: Open Terminal, enter:

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. Don ' t worry! Small series have been addicted to blockchain and smart contracts can not extricate themselves. Now take your hands from

directly in programs. We do not recommend that you use the sequence as you would with STL. The better way to use Tranquility is to encapsulate and use it for problems to be handled. What is the difference between this and GDI +? First, you can fully control the encapsulated ingress. Attention only provides a series of basic algorithms, which are rarely associated. You can define only interfaces and convert the pipeline and output formats. It can even replace any existing graphic interface. For

beginning of this article, if it is a block chain solution for a particular scenario, it is advisable to hyperledger fabric, of course, to build the private chain of the etheric square. The following figure is a comparison of some of the etheric square and fabric: The ether square is the same as Hyperledger: is to provide a platform for the implementation of the block chain business, business implementatio

transaction has the direction to prevent cheating behavior. Modeling Business Scenarios For the second section of the two cases, we are going to model, remove the core pain point, we must also have the requirements of accounting, in essence, in any case each node is both a service side, and customer side, then how to measure their contribution and how much to claim. Therefore, any blockchain platform must have a token system, otherwise the accounting will be very difficult. In the business

technological progress. Another is practical, Shenzhen before soon opened the first based on the blockchain invoice, now want to do the alliance chain related projects, in fact, a lot of opportunities, technology is relatively mature, do the project to support the family is very practical ah, here the blockchain and other technology is no different. 　　As a more pragmatic technology developer, in order to earn a living and focus on the development of

technologies can often handle well. However, because of their locality, the results still have serrations. And they do not deal with the adjacent relationship of diagonal pixel blocks. Also, the amplification factor of all these methods is fixed to 2 times, 3 times, or 4 times. In this paper, we introduce a novel processing method, which is suitable for the amplification of a single pixel in the feature information of a pixel image. We first deal with the relationship between the oblique and di
