Blockchain cross chain technology
blockchain includes public blockchain, joint (instry) blockchain and private blockchain. Public chain point-to-point e-cash system: bitcoin, smart contract and decentralized application platform: Ethereum
blockchain is a new application mode of distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm and other computer technologies
blockchain is an important concept of bitcoin. In essence, it is 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 bitcoin network transaction information, Used to verify the validity of its information (anti-counterfeiting) and generate the next block
extended data
according to the different degree of blockchain network centralization, three kinds of blockchains under different application scenarios are differentiated:
1. The blockchain with the whole network open and without user authorization mechanism is called public chain
2. The authorized nodes are allowed to join the network, and the information can be viewed according to the authority. It is often used in the inter agency blockchain, which is called alliance chain or instry chain
3. All the nodes in the network are in the hands of one organization, which is called private chain
alliance chain and private chain are also called licensing chain, and public chain is called non licensing chain
blockchain features
1, decentralization. Blockchain technology does not rely on additional third-party management institutions or hardware facilities, and there is no central control. In addition to the self-contained blockchain itself, each node realizes information self verification, transmission and management through distributed accounting and storage. Decentralization is the most prominent and essential feature of blockchain
2. Openness. Blockchain technology is based on open source. In addition to the private information of all parties involved in the transaction is encrypted, the data of blockchain is open to everyone. Anyone can query blockchain data and develop related applications through the open interface, so the information of the whole system is highly transparent
3. Independence. Based on consensus specifications and Protocols (similar to various mathematical algorithms such as hash algorithm used by bitcoin), the whole blockchain system does not rely on other third parties, and all nodes can automatically and safely verify and exchange data in the system without any human intervention
4. Safety. As long as 51% of all data nodes cannot be controlled, the network data cannot be arbitrarily manipulated and modified, which makes the blockchain itself relatively safe and avoids subjective and artificial data changes
5. Anonymity. Unless there are legal requirements, technically speaking, the identity information of each block node does not need to be disclosed or verified, and the information can be transferred anonymously
1) Chain retail: under the corporate organizational structure, capital gains have far exceeded labor gains. With the development of computer and Internet, a new generation of giant retail institutions accelerate the accumulation of wealth to capital. Chain business is the basic business model of human-computer community, and any behavior that has a positive contribution to human-computer community will be encouraged. The application of chain business model in the retail instry is concive to recing transaction costs, protecting consumer privacy and promoting intelligent cooperation
newmall: in the online mall of newmall, because there is no profitable commercial intermediary, the transaction cost of the seller will be greatly reced, and consumers, service providers and other participants can get the incentive of Newton's pass according to the contribution value (newforce)
new digital asset management: as a new digital asset of users, consumption data can be managed through tools such as newpay. Users really own the data, carry out authorization control, pricing and charging, and eliminate the data disclosure without knowledge
targeted advertising: users can set whether to accept marketing, as well as the required information type and price range through newpay and other tools. Advertisers set marketing plans through various marketing smart contract templates built into the system, including target users, incentive mode, settlement method, dynamic price adjustment rules, etc. Advertisers can accurately put in advertisements, make point-to-point settlement with users, and eliminate advertising fraud< br />2 Payment: the current payment cost is high, the efficiency is low, and the flexibility is poor. Through blockchain and other technologies, we can build a new generation of transaction and payment system. Internet of things devices based on newiot technology can access newchain at a very low cost. Smart contracts can be established between devices to realize automatic settlement and payment, meeting the high-frequency requirements in this scenario
Global Payment: through the global distribution of newchain infrastructure and newpay payment tools, cross-border transactions are simple and convenient, and the cost is extremely low
3) supply chain: goods are usually delivered to consumers through logistics, warehousing, customs clearance, sales and many other links. When there is after-sales service, there will be a corresponding reverse process. The current supply chain is basically opaque, and it is difficult for consumers to confirm the origin and circulation information of goods. For some instries, such as food, medicine and luxury goods, this is a big problem. Therefore, a transparent and credible supply chain system for all stakeholders is very important
through the combination of atomic hash, newiot, newchain and other technologies, the supply chain system will be credible, open and transparent, and generate more business innovation
4) self financing: the traditional financial service system has the characteristics of heavy workload, long cycle, high cost and poor flexibility, which is usually difficult to serve small and medium-sized enterprises and indivials. Through digital identity and credit, a new self financing system can be established
enterprise and indivial credit: enterprises and indivials establish a consistent credit system based on newid. Only after authorization, can a third party obtain credit records
Asset Securitization: through the smart contract template, financial organizations can create financial procts without human participation. Through the relevant token tools based on newchain, all kinds of assets can be easily valued or transformed into token on the chain
5) gaming: by combining with blockchain technology, a new game experience can be created: users are both players and rule participants, and virtual game assets are owned by users
automatic transaction of virtual game assets: through the cross chain and Oracle technology provided by newchain, the virtual items in various games can be easily recorded on the blockchain, and the automatic transaction can be realized
game with transparent rules: game developers can easily establish algorithm transparent game logic through newchain related smart contract tools to improve the fairness and transparency of the game
6) agriculture: Currently, there are many problems in agriculture, such as incomplete data and low degree of automation. Block chain combined with Internet of things technology can automatically collect, store and analyze proction data, save the high maintenance cost of centralized management system, rece the later maintenance cost, and help to improve the intelligent and large-scale level of agriculture
traceability of agricultural procts: by introcing the Internet of things equipment compatible with newiot standard into the process of agricultural means circulation, agricultural proction and agricultural procts sales, the safety and efficiency of the whole process of agricultural proction can be improved. Due to the non tampering characteristics of proction data, it can be widely used in scientific research and anti-counterfeiting purposes
intelligent planting: through the Internet of things sensor compatible with newiot standard, it can realize the all-weather monitoring of the planting environment and crop growth. Combined with newai, it can make intelligent decisions on the monitoring results, and build a complete set of intelligent planting system, which can discover risks in time, stabilize proction and increase income
7) public welfare: with its characteristics of decentralization, high transparency and tamper proof information, blockchain technology naturally meets the needs of the public welfare field. Public welfare organizations can store the whole process information from fund-raising, project progress, use of donation and feedback from recipients on newchain for the convenience of donors and the public< Public welfare audit: public welfare activities need public welfare audit to improve efficiency and maintain trust. Through newchain, newid and other technologies and agreements, every donation will be traceable. Public welfare institutions can track the later situation of the relief objects through relevant tools, which helps to enhance the fairness and transparency of public welfare
wildlife protection: using newiot technology, the data of rare wildlife resources can be recorded on newchain, so as to track the location, body index, etc. of each specific animal, providing key information help for migration scientific research tracking, combating poaching and trafficking.
Blockchain and artificial intelligence are the next era
There is a good combination between the twoblockchain is a new application mode of distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm and other computer technologies. 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
artificial intelligence, abbreviated as AI. It is a new technical science to research and develop the theory, method, technology and application system for simulating, extending and expanding human intelligence
Artificial intelligence is a branch of computer science, which attempts to understand the essence of intelligence and proce a new intelligent machine that can respond in a way similar to human intelligence. The research in this field includes robot, language recognition, image recognition, natural language processing and expert system. Since the birth of artificial intelligence, its theory and technology have become increasingly mature, and its application fields have also been expanding. It can be imagined that the scientific and technological procts brought by artificial intelligence in the future will be the "container" of human intelligence. Artificial intelligence can simulate the information process of human consciousness and thinking. Artificial intelligence is not human intelligence, but it can think like human and may surpass human intelligence At present, blockchain technology can be divided into three versions At present, in the first three versions, there are some problems, such as the lack of decentralization, low scalability, the mismatch between the incentive of the blocker and the best profit of the whole network, and the network always runs at the maximum capacity, such as bitcoin and Ethereum, which affect the efficiencyVelas combines the two to develop a public chain that can learn and improve itself
Velas enhances its consensus algorithm through artificial intelligence (AI) optimized neural network, and concts self-learning and self optimized public chain, aiming at improving the security, interoperability and high scalability of transfer process and intelligent contract. Velas adopts the dpos consensus enhanced by AI, which completely realizes decentralization without recing the security and transaction speed
technically, Velas has integrated functions and services such as cross chain payment, multi signature wallet supporting multi currency, anonymous transfer, etc. Its Ecosystem focuses on all application scenarios covering transaction and payment, such as exchanges, multi signature wallets, merchant platforms, etc. after AI is fully connected to the system, the transfer fee can be completely exempted
and complete decentralization through AI enhanced dpos (aidpos) & gt; AI chooses who to mortgage the token according to the needs of blockchain & gt; Velas only blocks when needed & lt; Between every 1 second and every 2 minutes & gt& gt; Scalability (up to 30000 TPS) & gt; Block procers are selected by artificial intuition< br />
first, if there is not much start-up capital in hand, how to raise funds to set up a company with a registered capital of 1 million yuan
Second, we are going to start business at home at the beginning, but we can't complete the instrial and commercial registration of family residence. What should we do< In fact, since March 1, 2014, the state has begun to adjust its policies and implement the system of subscription of registered capital. Even if there is no start-up capital, other methods can be used to register the company. In the new policy, the restrictions on the way, time limit and amount of capital contribution are cancelled. The purpose of the state's move is to encourage entrepreneurship. Even if you don't have any money, you can easily register a company with 1 million yuan in this way. In the future, when you make money, you can supplement the registered capital
What are the fees for registering a company in Shanghai, regardless of the registered capital? Zhihao has sorted out for you the expenses of business registration, seal engraving and tax registration certificate in the process of company registration, as well as the expenses of subsequent business tax declaration, taxpayer and registered address of the company
I. business registration fees. In the national policy, business registration does not need to spend money, free of charge
2. The cost of official seal engraving. A very important step to complete the instrial and commercial registration is to obtain the official seal. The cost of carving the official seal is 50 yuan / set, which is a necessary cost< Third, the cost of tax registration certificate. The fee is free< 4. Fees for Instry license and food hygiene license. If the company needs to apply for these certificates, there may be corresponding expenses< 5. The bank opens the basic account of the company. For bank account opening, the fee charged by each company may vary to a certain extent. The general fee is more than 500 yuan< 6. The cost of purchasing invoice. The company needs to buy tax cards, special printers, billing software and so on. The total cost is about 2000-3000 yuan< 7. If you need to apply for general taxpayer qualification and issue VAT invoice, the cost will be increased. If an enterprise is engaged in import and export trade, there are administrative charges when it goes through the import and export filing proceres, and the cost is about 2000 yuan.
8. If it is entrusted to an agent company, the cost of registering a million companies in Shanghai is not much, but in the process of registering a company, there may be a lot of cumbersome affairs to deal with, In this case, in fact, looking for an agent to complete the registration can save more time and energy. The total agent fee is about 500 yuan
simply speaking, the process of business registration in Shanghai is as follows:
check the name - register online - hand in the business establishment information - get the business license - engrave the seal - do the organization code certificate - do the tax registration certificate - open the basic account (taxpayer)
the detailed steps and cycle are as follows:
1. To approve a company name, it is better to submit 3-5 company names in the preferred order at a time to prevent plicate names. If it is submitted again, the approval time will be longer. The name of the company requires the company name, shareholder name, ID number and capital contribution ratio. 1-3 days
2. After the name is approved, fill in all the delivery materials, make an appointment, and submit the documents to the Administration for Instry and commerce; 7 days
3 and 7 days later, after obtaining the business license, we will handle the tax, code and stamp. 7 days to complete the documents
