Blockchain network migration

1. Theoretically, it can subvert the existing social networks, but in fact, it still faces many technical and policy problems. For example, decent, a popular blockchain content publishing platform in recent years, has crowdfunded nearly 5881 bitcoins, about 28 million yuan. This is a decentralized content sharing platform. Anyone can participate in it without any restrictions. However, in the world, it still faces the risk of policy regulation. Now we can only use one sentence to describe blockchain: ideal is full, reality is bony.

2. How can blockchain be connected in sequence
blockchain is composed of a series of blocks generated by cryptographic algorithm. Each block is filled with transaction records, and the blocks are connected in sequence to form a chain structure, which is the blockchain ledger
taking bitcoin as an example, when miners generate new blocks, they need to calculate the new hash value and random number according to the hash value of the previous block, the new transaction block and the random number. In other words, each block is generated on the basis of the previous block data, which ensures the uniqueness of the blockchain data
because subtle changes in transaction records will completely change the result of hash value, miners can't cheat when competing for computing power. Each miner must wait until the previous block is generated before starting to calculate the qualified random number according to the data of the previous block, which ensures the fairness of mining.

3. A protocol is a set of rules for managing a network. Blockchain protocol usually includes rules of consensus, transaction verification and network participation. Agreements often rely on economic incentives - which means they depend on an asset
generally, protocol level assets can also be used as local procts of the protocol (no platform required!) Bitcoin is a good example. Bitcoin (capital B) refers to the agreement. The agreement depends on the local asset: bitcoin (small b). This local asset is also used as the end proct: it's the user's means of payment, the store of value, and (to be honest) a degree of hype. Please note that bitcoin does not really provide a platform. It's not very friendly for developers trying to build new procts on it< On the other hand, Ethereum has three levels. It's an agreement that provides the basic rules. This is a platform that enables developers to build new procts on the system. Moreover, because its agreement contains a local asset, it also gets a built-in proct (in the form of ether)
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.

4. Blockchain service network is an Internet like blockchain infrastructure. It is the world's first blockchain service network based on blockchain technology and reflecting the second generation of intelligent Internet. It is also the largest alliance chain in the world. It provides high-level technical solutions for the development of smart city and digital economy in China Credible service carrier and infrastructure of modern social governance system
at present, the overall planning and top-level design of the blockchain service network have been completed, and the construction of more than 40 public city nodes in 31 provinces and autonomous regions has been completed. The blockchain service network will be tested internally for half a year. In the future, China UnionPay, together with the state information center, China Mobile and other partners, will actively promote security and function testing, technical architecture optimization, business operation scheme formulation, basic service capacity building, innovative application promotion and other work, and finally realize the commercial operation of the whole system
interested developers can view it on the official website of the blockchain service network.

5. For the first time, you can see how the company can find the direction and position in the blockchain instry. You can just follow his normal link to see.

6. All mining machines have such a normal phenomenon, the calculation of mining machine chip is not a stable output process, as long as the average computing power and daily income are stable
in addition, the computing power of mining machinery will fluctuate e to the status of mining machinery, working environment, network instability and other factors. The mine management personnel need to pay attention to check all relevant factors to protect the stability of income.

7. VAT invoice is also a kind of invoice. Enterprises with the qualification of general VAT taxpayer can apply to the competent state tax department for purchasing VAT invoice and issue it through the anti-counterfeiting tax control system. Enterprises with the qualification of general VAT taxpayer can dect vat by VAT invoice. Special invoice is the abbreviation of "VAT special invoice". An invoice issued for the sale of goods subject to VAT. After the implementation of the Provisional Regulations of the people's Republic of China on value added tax, in order to ensure the implementation of the tax dection system of value-added tax which belongs to extra price tax, it is printed and distributed for the use of enterprises. When taxpayers sell goods or taxable services, they shall issue special VAT invoices to the purchasers, indicating the sales amount and output tax amount respectively. The use of special invoice as dection voucher is limited to the general taxpayers who are both VAT buyers and sellers.

8. Let me summarize to the building owners that we can use the token to encourage and govern. For example, we can use weni to mobilize various types of community user groups and partners to build an ecosystem of consensus, sharing, win-win and autonomy.

9. Blockchain itself is a tool called decentralization and distrust. For example, when you graate from University, the current practice is to have a certificate recognized and issued by an authoritative authority as a certificate
this setting is troublesome, because it is a piece of paper, which can be forged, and there will be various gaps. The issuing authority is also a person, and there will be various gaps in the middle. As long as it is related to people, there will be various possibilities related to which media
blockchain provides a good opportunity. As soon as you graate, you can generate a record on the blockchain. No one can change this record. This thing exists objectively. As a physical existence, and then as a data existence, blockchain will be generated
in this way, it is easy for anyone who wants to find out where he graated from
this is similar to the big data often used in social networking (WeChat) and payment platforms (Alipay, Yi Bao).

10. Jinwowo group pointed out: blockchain technology will integrate with other information technologies with a new basic technology of information network, promote the evolution and deterioration of network, upgrade from traditional "information channel" to "network and platform, network and data", and endow all information including human and intelligent machine with more independent and secure capabilities, It will subvert the world information revolution.
