1. According to Hou Jietai: the so-called centralization refers to subtracting the mean value of a variable from its expected value. For sample data, each observation value of a variable is subtracted from the sample average value of the variable, and the transformed variable is centralized
for your question, subtract the mean from each measurement.

2. Nakamoto is the first person to discover bitcoin. Bitcoin is not issued by any institution, and the total amount is only 21 million yuan. The transaction of bitcoin needs the consent of 6 people!
3. Centralized wallet, also known as off Chain Wallet, completely depends on the company and server running the wallet. Bitcoin stored in the exchange is stored in the centralized wallet (off Chain Wallet). The private key is not owned by the user, but in the wallet project side of the centralized server hosting chain, the fund is usually entrusted to the server
private keys and assets are transferred to the wallet for centralized management. Users don't need to worry about the loss of the private key of this kind of wallet procts, resulting in the loss of funds; However, the capital risk will be more concentrated in the wallet project side and server side. When the centralized wallet is conquered by hackers, users will suffer unnecessary losses
decentralized wallets, commonly known as onchain wallets, have private keys maintained by users and assets stored in blockchains
decentralized wallets are often referred to as onchain wallets. The private key is handed over to the user. If the private key is lost, the wallet will not be able to help the user recover, and the funds will be lost forever. But the decentralized wallet is difficult to be attacked by hackers, and users don't have to worry about the self stealing of the wallet service provider
centralized wallets are where assets are stored, while decentralized wallets are where private keys are stored
except for the exchange, it is not recommended to use the centralized wallet, although losing the private key may help you find it. But there is always a risk that the company will run
a decentralized wallet is equivalent to a channel, a channel where you can master mnemonics to control your assets on the blockchain. For a decentralized wallet, the most important thing is to protect the security of the [private key]
the application fields of blockchain include digital currency, token, finance, anti-counterfeiting traceability, privacy protection, supply chain, entertainment, etc. with the popularity of blockchain and bitcoin, many related top domain names have been registered, which has a great impact on the domain name instry.

@ block chaining
to make complaints about the center is code open source, you can check, ensure that they will not install viruses and upload your personal data. p>
-
it doesn't matter if the wallet goes out of business, just export the private key and save it to other wallets
-
the exchange transfer fee is about 30 yuan per time, and the transfer from your wallet is only a few cents per time

For users,
may be more convenient,
but it hasn't been realized yet
7. Atoken wallet is a strictly decentralized wallet. The official promises not to save the user's mnemonics and private keys. As long as the user keeps the mnemonics and private keys, the digital assets will be in a safe state. There are many wallets in the market that are centralized. Users should pay attention to the risks when using them. Centralized wallets mean that the password and key of assets can be obtained. So digital wallet is better to choose decentralization.
8. The representative of all nodes is bitcoin core
core wallet, which needs to synchronize all blockchain data and takes up a lot of memory, but it can be completely decentralized. Light wallet relies on other all nodes in bitcoin network, only synchronizes data related to itself, which can basically achieve decentralization. Centralized wallet does not rely on bitcoin network, all data are obtained from its own centralized server, but the transaction efficiency is very high, and it can be received in real time. The account you register in the transaction platform is the centralized wallet.

to operate the ulord wallet, you need to download "Youyi" first, and then create your own wallet.

10. Before the birth of bitcoin, global information transmission was realized through the TCP / IP (Transmission Control Protocol / Internet Interconnection Protocol) protocol of the Internet to achieve high-speed and low-cost transmission. However, with the development of interconnection technology (Internet, Internet of things, VR / AR), the interaction between people and objects, people and information is more diversified, and more entities are digitized or token, Just the sharing and transmission of information can not meet the economic and social development, so when the entity is digitized or token, people pay more and more attention to the value transfer and how to transfer these assets and values point-to-point
after the birth of bitcoin, it is proposed to realize value transfer through decentralized bitcoin network. In the bitcoin system, all participants in the whole network are the supervisors of the transaction, and both parties can complete the transaction without establishing a trust relationship. Blockchain technology has changed the way people access and share information, creating a new distributed, point-to-point ecological society
at present, blockchain technology is mainly divided into three times in the market:
&&# 160; The first era is a point-to-point e-cash system represented by BTC< br />Ø&# 160; The second era is the open smart contract complete solution represented by eth< br />Ø&# 160; The third era is to solve the problem of eth performance shortage and block congestion, and strive to achieve better commercial value of public chain cluster
the global ecological cycle Foundation (hereinafter referred to as the foundation) was registered in the United States in 2020. Through the integration of ecological technology and information technology, the foundation is committed to promoting global land greening, maintaining ecological balance, and leveraging more social resources to create a sustainable green economic business model
the foundation is committed to exploring a new sustainable business model of global green economy and promoting the development of global green economy; Promote the formulation and implementation of policies and action plans of the international community in the fields of green development, ecological environment protection, desertification control and clean energy. Through the above continuous positive feedback circulation business model, the external social capital can be internalized effectively. The Foundation hopes to mobilize at least $20 billion of global funds to develop a green economy in 10 years
the project will focus on the use of innovative technologies and financial tools, including but not limited to green assets, blockchain (standard tools), professional review institutions (AUDIT), and cooperate with project stakeholders including enterprises, governments, audit firms, certification institutions, investors and so on, to jointly promote the development of landing projects< br /> Basic Proct Chain (BPC) endows the green instry with the concept of "consumers are shareholders", so that more users can get green rewards by using green ecological procts. It can be predicted that after the crazy speculation in the first decade of blockchain, the next decade will lead to a golden period of value investment. Under the POC consensus mechanism, relying on capacity proof (hard disk) and digital assets as the means of circulation, it will eventually return to the real world and promote the development of the real economy through scenario application, It will play an important role. In short, as long as we prove the relevance of all the related rewards generated by the network through the capacity, the data will be linked, real, open, transparent and searchable; The idea of everyone mining and one person, one vote will appear in a more green, low-cost and complete form
I hope it will help you
