Five challenges of financial blockchain Technology

1. Of course, this is OK
first of all, blockchain is actually a centralized database or a decentralized database, and all technical units are for better maintenance of the public database. Each node keeps a of data independently. Consensus algorithm is used to achieve the data consistency of the node's account book, and cryptographic algorithm is used to ensure the data can not be tampered, and the data can not be tampered and the security of data sending and receiving; Through the script system, the expression scope of account data is expanded
secondly, financial sharing center involves a large amount of financial data. We can combine the technical characteristics of blockchain with Financial Sharing Center. Next, I will combine the technical characteristics of blockchain with Financial Sharing Center
① distributed storage is a distributed database of the blockchain, and each node keeps a of the data independently. If this is combined with the Financial Sharing Center, The users who can join the "financial data on the chain" in the financial sharing chain are equivalent to the "nodes" in the blockchain network, and each user can keep a of the financial data separately, so as to achieve the purpose of sharing
② tampering is not allowed. A very important feature of blockchain technology is that the data cannot be tampered, To ensure the security of a data in the Financial Sharing Center, we need to consider the security as long as the financial data is involved.
of course, before doing the Financial Sharing Center, you must determine your specific needs, if necessary, first write a framework of the whole project, and then find a formal blockchain development team according to the needs, To help you develop this "Financial Sharing Center", we must pay attention to that before formal cooperation is reached, don't disclose the information of your project casually, in order to prevent the same kind from being copied.

2. With the emergence of cryptocurrencies such as bitcoin, this time tested financial framework is likely to be changed. With the power of blockchain and the rise of this new data based currency, the whole concept of money has been reversed. Although our current understanding of money has changed over the past few decades, thanks to credit cards and fiat money, cryptocurrency is the logical next step in this evolution
this is understandable for accountants, but what does it mean for entrepreneurs? Well, anyone interested in starting or maintaining a successful business will need a competent accounting team. With the change of financial environment, the experience and insight that business accountants need will also change. Understanding this coming paradigm shift can better help entrepreneurs prove their organization in the future, and may even help them save money on business expenses related to accounting
overview of bitcoin modern accounting
the current financial paradigm regards bitcoin, Ethernet and all other cryptocurrencies as assets. In the United States, for example, any form of cryptocurrency is considered property, not money. Although the IRS recognizes that bitcoin can be used as a "medium of exchange", bitcoin is not classified as currency because it usually has the function of "unit of account and value storage space"
as a result of this classification, changes in the value and quantity of cryptocurrencies are taxed as capital gains or losses. mining or buying a lot of bitcoin will lead to capital increase, which will make bitcoin subject to capital gains tax. The same is true for trading or selling cryptocurrency, as these events are treated as taxable capital gains and losses. Therefore, the accounting treatment of the holding amount of the comparative currency or other high-end stocks is roughly the same as that of other forms of equity (such as real estate or stocks)
forecast of bitcoin and accounting in the future
e to the legitimacy of blockchain and cryptocurrency in the financial sector, the accounting nature of bitcoin and other advanced currencies will also change. Although many potential changes are too far away to be accurately predicted, one aspect of accounting is bound to change dramatically, which will inevitably affect all entrepreneurs and business organizations. This aspect refers to audit
here's how blockchain and cryptocurrency are used to brutally disrupt the audit process, and what it means for companies that employ auditors? Because bitcoin is currently classified as the property that must pay capital gains tax, the audit method of its value is called immediate forensics analysis. However, the immediate verifiability of blockchain technology makes this audit method obsolete

when you track these changes and developments, please discuss with your organization's accountant or financial advisor. They can help you understand the further meaning of these events; In some cases, they can even show you what actions you can take to deal with these events, so as to increase your profits, rece your costs, and open up a new development path for your enterprise
on the other hand, if your accountants and auditors are at a loss about your research, consider updating your finance team.

3. Instry application of Newton
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.

4. 1. Blockchain in the field of payment: the cost of reconciliation, clearing and settlement between financial institutions, especially cross-border financial institutions, is high, and many manual processes are involved; The application of blockchain technology can rece the cost of reconciliation and dispute resolution between financial institutions, significantly improve the efficiency of the payment field, and make it easier for financial institutions to handle small cross-border payment business, which is concive to the realization of inclusive financial business. 2. In the field of clearing and settlement: different financial institutions have different infrastructure structures and business processes, involving many manual processes, which greatly increases business costs and is prone to errors. The application of blockchain technology, combined with the assets on the chain mentioned in the second point, can complete the point-to-point real-time clearing and settlement, so as to rece the cost of value transfer, shorten the time, improve efficiency, and both sides of the transaction can obtain good privacy protection. 3. Asset management: equity, bonds, bills and other assets are entrusted by different intermediaries, which increases the transaction cost of assets and brings the problem of forged vouchers. With the application of blockchain technology, this kind of assets can be digitized into digital assets on the chain. With the characteristics of irreversibility, non tampering and openness of blockchain, the efficiency of asset transaction can be improved and the cost of asset management can be reced. Because the characteristics of blockchain are irreversible and tamperable, the information is confidential and secure, the point-to-point transaction transmission is decentralized, and the information can be traced reliably; In order to rece intermediate costs and improve efficiency, it is not only used in accounting and auditing, but also can be applied to all walks of life. Now we can see the mode of blockchain cooperation operation from behind the operation of all walks of life. Therefore, blockchain will widely and profoundly change the way of human life, so the whole life service will enter the era of blockchain. In the process of Internet development, blockchain + physical instry, blockchain e-commerce and blockchain community operation can be applied to blockchain technology.

5. At present, the current situation of blockchain technology development in China is that there are more patents, less paper code, no independent security controllable underlying platform, and no integrated platform of software and hardware, which will directly lead to the technical risk of blockchain core technology being controlled by others, the financial risk of foreign open source platforms seizing the financial market, and the economic risk of foreign open source platforms penetrating China's real and virtual economy. Therefore, it is very important to realize the landing of blockchain application as soon as possible. Now there are landing applications all over the country under the support of policies. Changsha high tech Zone has officially launched a blockchain project, which is called SMIC blockchain service platform. It is a government enterprise service platform, cooperating with Bank of Changsha and Dean justice, and now it is the stage of collecting enterprises to join the chain.

6. Maybe, if you dig up krypton gold again and again, you'll make a lot of money. It's usually less than 100 grams an hour.

7. The mines in Outland should be the most valuable, but it's hard to mine, and the mines in pandaliya are also good
under the ideal situation of big bird mount + no one grabs the mines with you + opposing camp doesn't kill you + familiar with the mines, more than 1000g per hour
under normal circumstances, e to various interference factors, 500g per hour is good, minus 200g per hour, the actual income is 300g per hour, If you are engaged in manual mining, you should also consider the fatigue factor. The more mining, the lower the efficiency. It is not recommended to use this lowest level method of earning money. Just like the wage earners in big cities, they can barely earn a living (point card money), but they have no future

Blockchain:

blockchain is a new application mode of distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm and other computer technologies. The so-called

consensus mechanism is a mathematical algorithm to establish trust and obtain rights and interests between different nodes in the blockchain system.

blockchain has the characteristics of decentralization, distrust, scalability, anonymity, security and reliability:

the concept of blockchain was first put forward in the paper of Nakamoto Tsung in 2008. Blockchain can be understood as a public accounting mechanism (technical solution), which is not a specific proct. Its basic idea is: through the establishment of a group of public accounts on the Internet, all users in the network jointly keep accounts and check accounts on the account book, to ensure the authenticity and non tampering of information. And the reason why it's called & 8218; Block No. 8219; Chain, as the name suggests, is because the structure of data stored in the blockchain is composed of one by one on the network; Storage block; Each block contains all the information exchange data in the network within a certain period of time. Over time, the chain will grow

characteristics of blockchain

blockchain has the characteristics of decentralization, distrust, scalability, anonymity, security and reliability:

Decentralization: because the blockchain relies on each node to achieve the maintenance of the system and ensure the authenticity of information transmission, it is based on distributed storage data without centralized management by a certain center, Therefore, the attack and tampering of a node will not affect the healthy operation of the whole network

de trusting: the establishment of a connection between any two nodes does not need to trust each other's identity, and the data exchange between the two sides does not need the basis of mutual trust. Because all nodes in the network can play the role of ﹥ 8218; The supervisor; So don't worry about fraud

Extensibility: blockchain is a kind of underlying open source technology, on which various kinds of expansion, decentralized and distrusted applications can be realized

anonymization: both sides of data exchange can be anonymous, and nodes in the network can exchange data without knowing each other's identity and personal information

safe and reliable: because the activities between any nodes are supervised by the whole network, and the database uses distributed storage, for hackers, first, they can't disguise and cheat, second, they can't control the network by attacking a node

supply chain management

refers to the process of optimizing the operation of the supply chain from purchasing to meeting the final customers with the least cost. MBA, EMBA and other management ecation include the enterprise supply chain management

supply chain management is to coordinate the internal and external resources of enterprises to meet the needs of consumers. When we regard the enterprises in each link of the supply chain as a virtual enterprise alliance, and any enterprise as a department of the virtual enterprise alliance, the internal management of the alliance is supply chain management. However, the composition of the alliance is dynamic and changes at any time according to the needs of the market

effective supply chain management can help to achieve four goals: shorten cash flow time; Rece the risk faced by enterprises; Achieve profit growth

long; Provide predictable revenue

seven principles of Supply Chain Management: dividing customer groups according to the service characteristics required by customers; According to the customer demand and the profit situation of the enterprise, the logistics network of the enterprise is designed; Listen to market demand information and design procts closer to customers; Time delay; Strategic determination of

source of goods and procurement and establishment of win-win cooperation strategy with suppliers; Establish information system in the whole supply chain; Establish the performance evaluation criteria of the whole supply chain

although most people ignore the existence of agriculture, it does provide basic needs for our society. For young people, exploring the agricultural world is not attractive, mainly because of the lack of technical content in agricultural operation process. In addition, agriculture is a relatively complex business field, which needs more transparency and more perfect instry standards

and blockchain technology can change the status quo. Consumers all over the world prefer "clean" food, but procers have no way to verify the reliability of procts. Replacing the current supply chain management system with distributed accounting books can bring higher transparency and encourage consumers to buy food and procts after careful consideration

from a technical point of view, the use of blockchain in agriculture can realize intelligent supply chain management. But the whole agricultural management process needs a technical inspection. At present, agricultural technology solutions are either implemented by specific software or by service providers, but these two solutions are expensive and sometimes can not achieve the desired effect

recently, Emma, CEO of agridigital ( agriculture based on blockchain and smart contract supply chain management platform ); Emma Weston explained in detail how blockchain technology can solve the defects in the field of agriculture. The immutability of transactions and information in distributed account books is the key to solve all problems. Recording proct information on the blockchain is the most correct choice, and farmers, retailers and consumers can benefit from it

consumers are increasingly concerned about whether food is "clean" and organic, but procers and processors are usually unable to track and verify a series of accurate data related to procts from farm to table. Blockchain can help a lot. At present, there is no simple, accurate and effective way to track slave workers, raw material pollution and the origin of goods. At the same time, consumers are more willing to pay for the organic food with the above details. So far, we know that the root of the problem lies in certification and regulation, which are expensive, difficult to implement and confusing to consumers

the biggest problems faced by the agricultural sector are random pricing and high transaction fees. Once the supplier can not give a reasonable price, consumers are not willing to accept the final result. The cost of supply chain management greatly reces the interests of farmers, but also adds a lot of confusion to agricultural development

the development trend of block chain technology in the future agricultural field is still a mystery. However, there are many specific use cases, including land registration, big data monitoring, and even the application of smart contract. In the next ten years, there will be numerous use cases of blockchain in the field of agriculture, and the development prospect is very good
