Characteristics of bitcoin decentralization

2. Bitcoin is valuable under certain circumstances, but it is worthless under certain circumstances. Because it's not legal tender. It is impossible for any country to get the right to issue legal tender to use any mining machine. Bitcoin is just a virtual number. While it's still possible to change money, change it quickly! It's too late to wait until it's worthless at the end.

3. On the Internet, the most typical example of centralization is the portal website. By collecting all the information on the Internet on its own platform, the portal website forms a central node, and then extends many branches from this node. Generally speaking, only one node is making decisions. According to the analysis of jinwowo network technology, the characteristics leading to centralization are as follows:

1. The central node grasps the information of distributed nodes

2. The sub nodes do not master the information of other nodes (centralization, non-public transactions)

moreover, the pain point of centralization is that the security of the system depends on the security of the central node, and the distributed node has no control over it.

4. Q: What is blockchain technology? A: Blockchain technology can be understood as a public accounting mechanism. It is a technical solution rather than a specific proct. The basic idea is to establish a set of public account books on the Internet, in which all users in the network keep accounts and check accounts together, so as to ensure the authenticity and non tamperability of information. The reason why it is called "blockchain" is that the structure of blockchain storage data is composed of a chain of "storage blocks" on the network. Each block contains all the information exchange data in the network within a certain period of time, and the chain continues to grow over time. Q: What is the relationship between blockchain and bitcoin? A: Bitcoin used to be one of the most successful applications of blockchain technology. Specifically, the blockchain is a series of data blocks generated by the use of cryptography Association, and each data block contains the information of effective confirmation of multiple bitcoin network transactions. It can be said that bitcoin is a "killer application" of blockchain idea. Blockchain is the underlying technology of bitcoin, but its role is not limited to bitcoin. Q: What are the technical features of blockchain? A: Based on open source software and peer-to-peer network, blockchain can bring more advantages than traditional network in currency related fields such as transaction payment. These advantages include: decentralization, no need to trust the system, disintermediation, tamper proof, encryption security. Q: How does blockchain technology improve the authenticity and non tamperability of data? A: The newly added data blocks are linearly added to the end of the original block in chronological order, which constitutes the blockchain. In this process, the data is distributed in each computer. This decentralized storage method improves the authenticity and non tamperability of the data. When a transaction occurs, users all over the world can act as regulators. If we do not recognize the legitimacy of the transaction, the transaction cannot be concluded, and the data on the blockchain is maintained by us collectively. Q: Is there any potential defect in such a brain burning "blockchain"? A: Blockchain also has some defects to be solved, such as security risks, work efficiency and resource consumption. Since the supervision of blockchain depends on all nodes in the network, theoretically speaking, if you master more than 50% of the computing power of the whole network, you will be able to successfully tamper with and forge blockchain data. Secondly, e to the distributed storage, each node in the blockchain needs to keep a database, and any transaction in the network needs to be authenticated and recorded by other nodes, so the efficiency of the system is low. Finally, because the operation of the blockchain relies on the computing power contributed by the network nodes, these computing power do not proce actual social value, so it is generally considered that these computing power resources are "wasted". Application of blockchain in various fields when blockchain technology is published, many people think it is possible to realize DAC. DAC (full name) can be translated into distributed autonomous system, which refers to an organization system that runs autonomously without intervention and management through a series of open and fair rules. DAC has many forms. It may be a digital currency, a system or an entity, or even a driverless car. This kind of organization system can provide valuable services for customers in the form of currency transfer (such as bitcoin), asset transaction, domain name service, or any other business model. Therefore, through the idea of information sharing, blockchain technology is likely to bring profound changes in cost rection and security improvement to various instries. Application scenarios that existing blockchain technology can achieve: proof of existence can be used to confirm rights in the field of Internet finance, that is, blockchain can really realize "proving your mother is your mother". The smart contract guarantees the validity of the contract, such as the generation required by the electronic signature law; Reliability of methods for storing or transmitting data messages; The reliability of the method of maintaining content integrity; The reliability of the method used to identify the sender. The blockchain of the Internet of things can solve the problem of the coding standard interaction interface of the Internet of things. When an e-signature is signed by identity verification, the signature data is only under the exclusive control of the signer. Any changes to the e-signature after signing can be found, and any changes to the content and form of the data message after signing can also be found. The market forecasting community, August, is an example. Anyone can access and use August anywhere in the world, which may bring unprecedented liquidity and trading volume to the market. Asset trading NASDAQ OMX Group Inc is testing blockchain technology, which NASDAQ believes has the opportunity to transform traditional financial trading methods into bitcoin like ones. The bitcoin mode of e-commerce can be applied directly. Is it possible for e-commerce to become a "harmonious" market without supervision? Social news magmavc has invested $400000 in getgems (formerly known as gems), a start-up project for decentralized social communications applications. File storage directly impacts and even subverts the traditional cloud computing architecture. Chain, a data API blockchain API service provider, has received a $9.5 million investment led by Khosla ventures. Wall Street's financial companies are investing in blockchain and seizing the beach. Visa, NASDAQ and Citigroup also invested in chain, an old Jinshan blockchain start-up, with a financing amount of US $30 million. In the financial field, what can blockchain do? Specifically, in the financial field, in addition to providing a trading platform for bitcoin, Jiuding investment believes that blockchain technology can also greatly improve various asset trading systems other than the existing digital currency. For example, it plays an important role in the post transaction market proceres such as the liquidation and settlement of financial derivatives, foreign exchange, private equity, energy credit linked investment procts and other assets. In terms of speed, the time required for settlement audit in the U.S. securities market is 2 to 3 days. The application of blockchain technology is expected to rece the settlement audit time from hour level to minute level or even second level, thus recing the settlement risk by 99%, and recing the capital cost and system risk. In the blockchain, transaction confirmation and settlement are carried out at the same time. After the node transaction is confirmed by the system, it is automatically written into the distributed ledger, and the corresponding distributed ledgers of all other nodes are updated at the same time. The automatic operation mechanism can greatly shorten the settlement cycle. In terms of expenses, under the current settlement mechanism, in order to achieve a shorter settlement cycle, it is necessary to increase the settlement cost and initial investment expenses significantly. The emergence of blockchain technology makes it possible to rece the settlement cycle more efficiently and quickly, and rece the transaction intermediate proceres, so as to save a lot of money, which is the market space of the related blockchain instry. In terms of security, the integration of blockchain technology into smart contract technology can process complex derivatives transactions programmatically, making clearing more standardized and automated. The time linear stacking feature of the block itself can help the regulators identify and discover illegal operations. At the same time, the smart contract can change the compliance inspection into automation and minimize the possibility of violation from the beginning of liquidation. The 24-hour uninterrupted operation of blockchain technology can also make the data exchange processing of Pan state exchange more stable and reliable. In addition to securities transaction settlement, blockchain can also be used to register and issue digital asset ownership. Blockchain technology can greatly enhance program automation, while smart contract can write many complex derivatives trading terms into the registration and issuance program supported by blockchain technology. When a transaction occurs, blockchain network can quickly and correctly execute. In November 2015, LINQ, a new blockchain technology project cooperated by Nasdaq and chain, has completed the first private equity transaction using the blockchain based issuance and trading platform. The application prospect of blockchain in the field of accounting has also attracted the attention of a large number of people in the instry. Accounting, auditing and compilation cost a lot for global enterprises and the four accounting firms. Automatic accounting based on blockchain technology can greatly rece the relevant costs. The company does not need to recruit special auditors to audit the account book, and all transactions can be stored in the internal blockchain. Due to the irreversibility and time stamp function of the blockchain, the external auditors and regulators of the four major accounting firms can monitor the company's account books in real time by tracking these blockchains. At the same time, the institutions can greatly rece the dependence on the auditors to audit financial transactions and make the audit business more efficient. With the increasing maturity and application expansion of blockchain technology, blockchain start-ups in developed countries have sprung up. At present, the world's leading blockchain companies generally focus on transaction, payment, clearing, Internet of things and other pain point businesses. Some companies have achieved a certain scale, and have developed a relatively clear business model. At the same time, many companies have extended their business in the blockchain instrial chain, covering payment, transaction, risk control, etc., making full use of the multi-point coordination effect. At present, Jiuding investment is also focusing on the projects and applications of various blockchain technologies.

5. I don't know what you mean

6. As an almost perfect monetary system, bitcoin has five characteristics different from traditional currency
first, decentralization. Bitcoin is a point-to-point, decentralized digital currency. It does not rely on specific institutions to issue, does not need any government and institutions to carry out credit endorsement, and uses cryptography design to ensure the security of each link< Second, anonymity. You can send and receive bitcoin without providing any personal identity information< Third, scarcity. The total number of bitcoins is limited to 21 million and is expected to be issued in 2140< Fourthly, the transfer cost is low. With bitcoin transfer, no matter how much the amount is, you only need to pay a very low fee. The transfer fee can be set freely. At present, it is recommended to pay 0.0005 bitcoin fee for each transfer< 5. Convenient global circulation. In any country, any intelligent terminal connected to the Internet can carry out bitcoin transfer and transaction
I hope I can help you! Hope to adopt!

7. Bitcoin is based on a set of cipher codes and generated by complex algorithms. This rule is not interfered by any indivial or organization and is decentralized; Anyone can download and run the bitcoin client to participate in the proction of bitcoin; Bitcoin uses electronic signature to realize circulation, and checks repeated consumption through P2P distributed network. The generation and consumption of each bitcoin will be recorded through the P2P distributed network and informed to the whole network. There is no possibility of forgery. Bitcoin does not rely on specific currency institutions to issue, it is generated through a large number of calculations of specific algorithms. Bitcoin economy uses a distributed database composed of many nodes in the whole P2P network to confirm and record all transactions. The decentralized nature and algorithm of P2P can ensure that it is impossible to artificially manipulate the value of bitcoin through mass proction.

8. Bitcoin is a virtual cryptocurrency based on decentralization, peer-to-peer network, consensus initiative, open source, and blockchain as the underlying technology. It was proposed by Nakamoto in 2008 and born in 2009
bitcoin does not have a centralized issuer. It is generated by the calculation of network nodes. It can be bought and sold on any computer connected to the Internet, and has a strong scarcity
Decentralization: bitcoin is the first distributed virtual currency. The whole network is composed of users without a central bank. Decentralization is the guarantee of bitcoin's security and freedom

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

exclusive ownership: private key is required to manipulate bitcoin, which can be stored in any storage medium in isolation. No one can get it except the user himself

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

no hidden cost: as a means of payment from a to B, bitcoin has no cumbersome quota and proceres. If you know the other party's bitcoin address, you can pay

cross platform Mining: users can explore the computing power of different hardware on many platforms

9. Absolutely not

10. For bitcoin, don't invest any more. It's a complete gamble. Remember, don't participate, especially at this stage. The threshold itself is very low. Bitcoin is not money. It can be divided into any large unit, such as 0.0000015 bitcoin. I don't know when the concept of bitcoin was changed into bitcoin. It can be worthless at any time
