1. digital currency is a virtual currency based on node network and digital encryption algorithm, which can be exchanged at will. The place of digital currency is just there. All the big domestic star traders, such as silktrader, fire coin, coin security, etc. The owner of digital currency can communicate with others on the platform through the matchmaking system, or directly purchase digital currency with legal currency through the legal currency channel.

2. I don't know what the recent mining system is? But I can teach you how to distinguish the application of blockchain technology

blockchain technology has several characteristics, such as decentralization, distributed storage, traceability and non tampering

the building owner can judge from the above characteristics. Decentralization means that everyone can view the data of the application of blockchain technology, but it can not be tampered with, and it will not lose data e to a single node, so we can see the source of each application. Some fans of Nanning blockchain development also have some understanding of these applications< br />

3. This is a comprehensive and in-depth book on blockchain technology, which focuses on the implementation principle, consensus mechanism, application scenarios and future development direction of blockchain. This book consists of five chapters. The main contents are as follows: introce the origin and successful application of blockchain from the development history and principle of bitcoin and blockchain; From the combination of blockchain and traditional instries, artificial intelligence, finance, big data and other aspects, this paper describes the great technological changes that blockchain can bring to people; This paper introces the main application scenarios and corresponding cases of blockchain technology, including proof of existence, smart contract, supply chain, identity verification, asset transaction, forecast market, e-commerce, logistics, file storage, medical treatment, etc; This paper introces the current successful blockchain technology practice projects from the aspects of principle, technology innovation and development, including Ethereum, notarization, bitstock, Ruibo and super ledger; This paper describes the future blueprint of blockchain technology from the aspects of the evolution of blockchain network itself, the Internet of things and the Internet, which is to build the next generation Internet based on credit
in the bitcoin system, the number of bitcoins issued by each block decreases with time. Each block from Genesis block will issue 50 bitcoins to the bookkeeper of the block, and then the number of bitcoins issued by each block will be reced by half every four years (210000 blocks), and so on, until the number of bitcoins is stable at the upper limit of 21 million [19]. There will be a service charge in the process of bitcoin transaction. At present, the default service charge is one in ten thousand bitcoins, which will also be recorded in the block and rewarded to bookkeepers
with the soaring price of bitcoin, more and more people join the bitcoin mining instry. How long does it take to dig a bitcoin? How amazing is the power consumption of bitcoin mining machine? First of all, let's take a look at the "blockchain". The core principle of bitcoin is "blockchain". Each block corresponds to a bill. Linking all blocks is a blockchain. Any transaction information and transfer records are recorded in the blockchain. It should be noted that the blockchain exists in the whole Internet, so no bitcoin holder is worried about the loss of bitcoin
blockchain is probably such a structure. Let's explain it briefly. Taking the bitcoin blockchain as an example, the blockchain is not only bitcoin blockchain. As early as 2009, there was only one blockchain, bitcoin blockchain. In recent years, there have been other blockchains. In a moment, I will also introce the blockchain of Ethereum, or bitstock, as well as various blockchains. After the development of blockchain, Now it has entered the public chain and private chain. Just like bitcoin, the public chain is an account in the world. Bitcoin has only one blockchain in the world, which is owned in the world. Later, it developed to some financial institutions, which want to use blockchain to do things. It can't do things on a blockchain without national boundaries. Bitcoin blockchain is global, There is no sovereignty to manage it, no central organization to manage it, and almost no one can harm it. Not only hackers can't harm bitcoin blockchain, but also the government can't harm bitcoin blockchain.

In the traditional supply chain finance, financing difficulty, high financing cost and cumbersome financing process have always been one of the bottlenecks restricting small and medium-sized enterprises to become bigger and stronger. Banks rely on the ability of core enterprises to control goods and regulate sales. For the sake of risk control, banks are only willing to provide factoring services to upstream suppliers (limited to first tier suppliers) with direct accounts payable obligations of core enterprises, or provide prepayment or inventory financing to their downstream distributors (first tier suppliers). As a result, the demand of secondary and tertiary suppliers / distributors with huge financing demand can not be met, the business volume of supply chain finance is limited, and the small and medium-sized enterprises can not get timely financing, which will easily lead to proct quality problems and damage the whole supply chain system

to solve these problems, we can make use of the characteristics of decentralized, tamper proof and distributed ledger of blockchain technology to build a blockchain supply chain financial platform

The core enterprise issues a / R certificate to the distributor. After the distributor signs the receipt, it indicates that it has signed the purchase and sales contract and the core enterprise delivers the goods

Because of the shortage of funds, distributors need to borrow money from finance

3. After the financial institutions have approved, the amount of loans will be sent to the core enterprises

The distributor will repay the loan and interest after selling the goods
