The decentralization of blockchain refers to the form of social relations and content generation formed in the process of blockchain development. It is a new network content proction process relative to "centralization"

blockchain is an important concept of bitcoin, which is essentially a decentralized database. At the same time, as the underlying technology of bitcoin, it is a series of data blocks generated by using cryptographic methods. Each data block contains the information of a batch of bitcoin network transactions, which is used to verify the effectiveness of its information (anti-counterfeiting) and generate the next block

blockchain is unified in the whole network, so it is logically centralized. From the perspective of architecture, blockchain is based on peer-to-peer network, so it is decentralized. From the perspective of governance, blockchain makes it difficult for a few people to control the whole system through consensus algorithm, so it is decentralized

characteristics of blockchain Decentralization:

decentralization, not without the center, but by the node to freely choose the center, freely determine the center. In short, centralization means that the center determines the node. The node must depend on the center, and the node cannot survive without the center

in a decentralized system, anyone is a node, and anyone can be a center. Any center is not permanent, but phased, and no center is mandatory for nodes

with the diversification of network service forms, the decentralized network model becomes more and more clear and possible. After the rise of Web2.0, the services provided by Wikipedia, Flickr, blogger and other network service providers are decentralized. Any participant can submit content, and Internet users can create or contribute content together

1. Bitcoin

the concept of bitcoin was first proposed by Nakamoto on November 1, 2008, and was officially born on January 3, 2009. According to the idea of Nakamoto, the open source software is designed and released, and the P2P network on it is constructed. Bitcoin is a virtual encrypted digital currency in the form of P2P. Point to point transmission means a decentralized payment system

2. Litecoin (LTC) is an improved version of digital currency inspired by bitcoin. It was designed and implemented by a programmer who worked in Google. It was released on November 9, 2011. Lightcoin and bitcoin have the same implementation principle in technology, but the creation and transfer of lightcoin is based on an open source encryption protocol, which is not managed by any central organization

characteristics of bitcoin currency:

1. Decentralization: bitcoin is the first distributed virtual currency, and the whole network is composed of users without a central bank. Decentralization is the guarantee of bitcoin's security and freedom

2. Global circulation: bitcoin can be managed on any computer connected to the Internet. No matter where you are, anyone can dig, buy, sell or collect bitcoin

3. Exclusive ownership: private key is needed to control bitcoin, which can be stored in any storage medium in isolation. No one can get it except the user himself

4. Low transaction cost: bitcoin can be remitted free of charge, but a transaction fee of about 1 bitfen will be charged for each transaction to ensure faster transaction execution

3. Blockchain is an important concept of bitcoin. It is essentially a decentralized database. At the same time, as the underlying technology of bitcoin, it is a series of data blocks generated by using cryptographic methods. Each data block contains a batch of information about bitcoin network transactions, Used to verify the validity of its information (anti-counterfeiting) and generate the next block.

4. A lot, but it will take a long time.

5. The essence of money is the general equivalent. It has the functions of value scale, circulation means, payment means, storage means and world currency. It is a certificate issued by the state or an organization authorized by the state for the distribution of goods in the whole society
it is different from the general equivalent: first, it is proced at different times; The general equivalent comes first and the currency comes second; Second, the general equivalent is not fixed in time, region and material quality, while the currency is fixed by gold and silver
money is a special commodity that acts as a general equivalent, a tool used as a medium of transaction, a storage value and a unit of account, and a material and symbolic appendage of people's commodity values. It includes not only currency in circulation, especially legal currency, but also all kinds of savings deposits. In the field of modern economy, only a small part of the field of currency is shown in the form of real currency, that is, the paper money or coins used in practice, and most transactions use cheques or electronic money. Currency area refers to the circulation and use of a single currency countries or regions
the essence of money at least includes the following aspects: first, money is issued by the state or institutions authorized by the state, which is the proct of the emergence of the state. Before the birth of the state, money can not be proced. Second, the scope of currency issuance is nationwide. Third, the object of money distribution is commodity (I use the concept of commodity here, and I emphasize here that only procts that realize exchange are commodities, and they are not commodities before they are exchanged with currency or other rights and interests.)
different currency areas need to introce the concept of exchange rate when they exchange currencies with each other. In modern economy, money plays a fundamental role. In macroeconomics, money is not only cash, but also cash plus a part of assets.

6. CME Group, the world's largest derivatives exchange, announced that it would launch Ethereum futures on February 8, 2021. The new contract will be settled in cash, and the transaction is currently awaiting regulatory review and approval from the US Commodity Futures Trading Commission
according to CME's official announcement, each contract will have 50 units of Ethereum, and the derivative will be open for trading from 5 pm to 4 pm from Sunday to Friday. "Building on the success of bitcoin futures and options, the CME Group will add Ethereum futures to the crypto asset risk management solution in February," the CME said
the Xueshuo innovation blockchain Technology Workstation of Lianqiao ecation online is the only approved "blockchain Technology Specialty" pilot workstation of "smart learning workshop 2020 Xueshuo innovation workstation" launched by the school planning, construction and development center of the Ministry of ecation of China. Based on providing diversified growth paths for students, the professional station promotes the reform of the training mode of the combination of professional degree research, proction, learning and research, and constructs the applied and compound talent training system.
