Implementation of BTC in Python

1.

They are:

bitcoin

the concept of bitcoin was first proposed by Nakamoto in 2009. According to Nakamoto's ideas, the open source software was designed and released, and the P2P network was built on it. Bitcoin is a kind of P2P digital currency. Point to point transmission means a decentralized payment system

bitcoin cash

bitcoin cash is a new version of bitcoin with different configurations launched by a small number of bitcoin developers

extended data:

virtual currency refers to non real currency. Well known virtual currency, such as network company's network currency, Tencent company's Q currency, Q point, Shanda company's voucher, Sina's Micro currency (used for micro games, Sina reading, etc.), chivalrous Yuanbao (used for chivalrous road game), silver pattern (used for bixue Qingtian game)

the popular digital currencies in 2013 are bitcoin, Leyte coin, infinite coin, quark coin, zeta coin, BBQ coin, pennies (Internet), invisible gold bar, red coin and prime currency. At present, hundreds of digital currencies are issued all over the world. Popular in the circle & quot; The legend of "bitcoin, Wright silver, infinite copper, pennies aluminum"

2. For example, I borrow money from you in a village. Normally, if I am afraid that you will not repay the money, I can find an intermediary recognized by everyone, such as the village head as the guarantor, and sign an IOU. In this way, if you default at that time, I can find an intermediary to prove that you really owe me money, But there are two problems: 1. What if the village head finds out that his long lost son colludes with him to cheat you on money? 2. What if the middleman dies on the spot the next day! This is about trust and security. If the method of blockchain is to provide you with the certificate of the whole village (distributed), so that everyone knows about it and the other party can't default on it. Second, even if a small number of people or village heads deny (some nodes commit crimes) that they have lost the IOU or tampered with the content, there will still be others to make the basis

above, explain the two problems of building owners: 1. Decentralization, because the account book records are not centralized in the hands of each participant, and you will get paid if you save and keep accounts. 2. Since I can get rewards by saving and keeping accounts, can I just keep accounts instead of storing them? If you have a mining pool, you can keep accounts for it and store it for you. In this way, you can still get good rewards. There are only a few mining pools in the world, so they are centralized

BTC (business to customer)

also known as B2C, e-commerce according to a classification of trading partners, that is, commercial institutions to consumers of e-commerce. This form of e-commerce is generally based on the network retail instry, mainly with the help of the Internet to carry out online sales activities

B2C mode is the earliest e-commerce mode in China, marked by the formal operation of 8848 online mall. B2C means that enterprises provide consumers with a new shopping environment through the Internet - online store, where consumers shop online and pay online

because this mode saves the time and space of customers and enterprises, and greatly improves the transaction efficiency, especially for busy office workers, this mode can save valuable time

It combines the intranet with customers through B2B website, and provides better service for customers through the rapid response of the network, so as to promote the business development of enterprises. In recent years, B2B develops rapidly and tends to be mature

three otos (online to offline)

also known as o2o, namely "online to offline". The core of the business model of oto is very simple, which is to bring online consumers to real stores, pay online to buy offline goods and services, and then enjoy offline services

extended materials:

6. I have, there are Python entry-level to advanced, python actual combat projects, python + AI all have!!!! But I can't send links

my result is like this, which can be printed out

8. Learning any programming language, is to achieve a project, to solve practical problems. Whether the project is large or small, it is related to a lot of knowledge and skills
for example, to write an application of file resource manager, we need MVC design pattern, component construction, object collection and operation, packaging and deployment, multithreading traversal and asynchronous I / O operation and other knowledge moles. It is difficult to complete a project without any mole
therefore, completing a project is like completing a jigsaw puzzle. You need to complete each knowledge mole and then put it together into a project. In this way, project driven learning is generally recognized as the most efficient programming learning method at present:
easy to get started: as long as you master the basic knowledge and programming skills, you will have the ability to complete simple projects, You can start using this learning method
make up for what you lack: in the process of doing a project, you can test your learning achievements, find the knowledge moles you lack, and make targeted learning more efficient
a sense of achievement: the achievements of learning are reflected in the projects that can solve practical problems, so that learning can get immediate feedback, and the sense of achievement is overwhelming
how to effectively learn Python from scratch through project driven? Gnawing thick teaching materials, or watching a variety of video tutorials, it is obvious that they can not start to do their own projects. You need to start with actual projects.
