1. Before, when we talked about decentralized applications, we always thought of foreign procts, such as Ethereum. But when we talk about this topic today, I think more about China's own Asch, a new generation of decentralized application development based on side chain technology<
arch is a decentralized application development, and it is also the first decentralized application in China. Its purpose is to help developers quickly create decentralized applications. The system is easy to use, flexible and safe
in terms of mode, it is similar to Ethereum and belongs to blockchain service, but the implementation mechanism is quite different. Taking Ethereum as an example, its biggest feature is that it greatly expands the functions of the script engine, adds new instructions such as reading blockchain, charging and jumping, and relieves stack memory, function call depth and script length restrictions. However, this method has a big disadvantage that the application code itself and the data generated by the application exist in the same blockchain, resulting in the rapid expansion of the blockchain
but arch is different. Its extensibility is not realized by transaction script, but by side chain. There is a main chain and several side chains (mainly provided by developers) in the ash system, but each chain only supports a limited number of transaction types. The logic of transaction or contract is written directly by the host language, not by the transaction script
the advantages are as follows: firstly, it reces the difficulty of contract programming; secondly, it avoids blockchain expansion; thirdly, each application can customize personalized blockchain parameters<
ash does not directly crypti (decentralized, blockchain based app store) or lisk (it is a new generation, allowing JavaScript development and distributed applications to use an easy-to-use, fully functional ecosystem), But it will refer to crypti's architecture and reuse some of its code, but not too much
there are two main differences.
crypti uses dpos, on which we add pbft algorithm to enhance consistency and rece double payment risk
we use C + + language to write some key moles, and nodejs is still used to write the non performance hot parts.

2. Now, Bank of Changsha also cooperates with a public platform of SMIC blockchain, which seems to be a blockchain loan for small and micro enterprises.
3. You can register as a member of haobtc, and then you can be drawn to our user group. There are many blockchain celebrities, who will learn a lot about blockchain.
4.
Yes, the current deception is not surprising. In short, you should be more careful
with the rapid development of mobile communication, online dating has become a widespread form of communication, but there are some sweet traps set by outlaws. How to avoid being cheated in the complicated virtual space, so as to avoid unnecessary property losses
for example, he said that in his uncle's home in Taiwan, he sent a table of food, enlarged the picture, and you can see the logo of the drink, which is obviously a mainland brand, which needs to be seen carefully
5. Chongqing jinwowo analysis: blockchain also comes with the technology of transaction confirmation. To realize the automatic confirmation of movable property rights for all participants in the supply chain, and form a common non tamperable record on the block chain, so as to solve the pain points in the existing right registration and right realization.
6. A: 1. The most common methods of cost accounting in commercial enterprises are purchase price method and selling price method
2. Purchase price accounting, also known as "purchase price bookkeeping, inventory and sales", is an accounting method that controls the purchase, sales and inventory of goods by the person in charge of the physical object (or counter group) based on the total amount of purchase price. Its accounting features are: after the purchase of goods, register the sub ledger of goods in stock set by the person in charge of the goods, only recording the amount of purchase price, not the quantity; After commodity sales, credit the "commodity sales revenue" account according to the actual sales revenue, do not carry forward the cost of commodity sales at ordinary times, conct regular physical inventory, find out the actual quantity, and calculate and carry forward the cost of commodity sales with the final purchase price method. This method is suitable for selling bulk commodities with large unit value. The disadvantage is that it's troublesome
3. Supermarkets and department stores usually use the "selling price method" to calculate the cost of goods. Price accounting method is suitable for retail businesses with complicated commodities, but the premise is that the price is uniform (indivial price changes also need to go through relevant proceres), the cost of sales is carried forward according to the price in each period, the price difference rate between purchase and sale is calculated at the end of the month, and then the price difference between purchase and sale of the sold commodities is obtained, and then the cost is adjusted. This accounting method is not applicable in today's market economy.

7. It has been sent out, please check.
8. In theory, this is a good idea, which can better regulate people to use blockchain technology
from the perspective of blockchain technology development, it can be divided into three stages: the first stage is the application of digital currency such as encrypted currency, transfer, remittance and digital payment system; The second stage is the application of encrypted stocks, bonds, futures, loans, smart assets and smart contracts; The third stage will be applied in government, health, science, culture and art. At present, the application of blockchain technology is only in the process from the first stage to the second stage< At present, blockchain banking business includes: 1. P2P cross-border payment and remittance of point-to-point transactions, trade settlement, and trading of securities, futures and financial derivatives contracts. 2. Registration. Blockchain has a reliable database to record all kinds of information, and has the characteristics of credibility and traceability for the stored anti money laundering customer identity data and transaction records. 3. Right confirmation. For example, the proceres such as the right identification of the transferred items registered in the equity law system can be realized through the blockchain technology. 4. Intelligent management. Because the "smart contract" has the automatic detection validity and meets the program conditions, the contract will automatically process the interest payment and dividend, avoiding the risk of credit default caused by human intervention
R3 in foreign countries is a blockchain alliance, which can be regarded as an institution to formulate unified standards. Ethereum and distributed content publishing platform decent are projects based on blockchain technology.

9. I have never heard of this organization, let alone its members
R3 company, founded in New York in the second half of last year by fintech r3cev, is one of the leading technology companies adopting blockchain technology, focusing on the research of financial technology solutions based on blockchain. At present, a group composed of more than 40 international banking institutions has been established to build a customized Ethereum based cross-border blockchain solution. The members of R3 alliance include Citibank, Bank of America, Goldman Sachs Group, JPMorgan Chase, UBS group, Morgan Stanley and other financial institutions. It is the largest blockchain alliance so far. R3 alliance plans to explore other areas, including: distributed ledger interoperability, privacy, authentication, scalability, including cooperation with Microsoft to use its azure blockchain as a service to implement blockchain technology among banking partners
of course, in addition to R3, there are many other blockchain organizations or enterprises at home and abroad. In Beijing, Shanghai and other first tier cities. Blockchain projects are even more numerous, especially content sharing platform decent based on blockchain technology and bitcoin related projects.
