Blockchain currency bank

1. blockchain will not lead to the disappearance of banks. Blockchain will only improve the business of banks
at present, some well-known financial institutions in the world have begun to pay attention to blockchain and have carried out corresponding research and development. But banks will only make use of blockchain and will never let blockchain replace themselves
the underlying technologies of bitcoin, Ruitai and Laite are blockchain, but no one can replace the bank.

2. 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.

3. There are two roles and four moles in the cross-border payment solution based on euz. The two main roles are the gateway and customer participating in the euz payment. They are as follows:
the first role is gateway, which can be bank, market maker, liquidity provider, etc. The main function of the gateway is to let the legal assets in reality enter the blockchain payment and settlement network
the second role is customers, which can be all kinds of international trade customers. Customers are the parties involved in the blockchain payment transaction, and jointly participate in the confirmation of transaction information. In the process of transaction, once either party does not confirm the transaction, the transaction cannot be formally effective. Through this common verification, the risk of information opacity is greatly avoided, and the risk of cross-border payment in international trade is reced
the four functional moles in blockchain payment and settlement are the core business logic moles in cross-border payment
the first function mole is network connector. It is a tool to help all kinds of institutions access blockchain payment network as gateway. Network connector is a "plug and play" function mole, which can be integrated with the existing international payment and settlement system, so that banks can process cross-border payment business through blockchain. The mole is connected with the remitting bank and the receiving bank to exchange personal information, expenses, delivery details, payment details, etc. After the system confirms the transaction information of both parties, the mole connects the blockchain payment ledger for settlement processing, and notifies all parties to confirm the transaction
the second function mole is blockchain payment ledger. Banks, market makers, etc. access blockchain payment books as nodes
the third function mole is the market maker client. The market maker submits digital assets to the blockchain payment account book, and the settlement platform can realize the function of market maker through internal exchange settlement or integration into the blockchain payment network through this mole
the fourth function mole is transaction client. Customers can directly operate blockchain payment settlement through the client.

5. In addition to the postal service and Weizhong, the Bank of Changsha is now cooperating with a public platform called SMIC blockchain, which seems to be a blockchain loan business.

6. If we look at the current poverty situation in Africa, I'm afraid it will be a long time
let's see what others say.

7. Recently, a new concept of digital wallet has emerged. The platform uses the smart dog to carry out the so-called "moving bricks to cash out" and "saving money to earn interest". I think this kind of investment is very risky and has no legitimacy. Therefore, we should be cautious in investment. If we have to do so, we should first get the principal back and then use the profits to make rolling profits. In this way, even if there is a loss, we don't recommend to do promotion, which will hurt our contacts. Moreover, these so-called recommenders exaggerate and have nothing to do with reality. So the people who are looking for you also want to earn your money. Be careful!

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. Flint has no control and no capital pool. Based on the blockchain technology, the distributed ledger is maintained by the whole network, and the public general ledger data is made public all over the world. The funds of all depositors are stored in the accounts of the bottom users of the blockchain, basically realizing the role of blockchain bank.
