区块链与现有银行的关系,区块链与现有银行的区别

区块链是一种基于分布式账本技术，它可以记录所有的交易，并且是不可篡改的。它的发展使得货币可以在网上安全可靠地流通。区块链与现有银行的关系，以及它们之间的区别，是一个值得探讨的话题。本文将拓展三个相关关键词：去中心化、自治性和安全性。

区块链技术的特点是去中心化，它不依赖于任何中心机构或组织，而是由一个分布式网络构成。这种网络是由节点构成的，每个节点都可以查看整个网络的数据，并参与共识机制，以确保网络的安全性。相比之下，现有银行的系统是中心化的，它们依赖于中央机构来管理数据和资源。

区块链的另一个特点是自治性，它不受任何中央机构的控制，而是由参与者自发地协作来管理网络。这种自治性使得区块链系统能够更快地响应变化，并且可以更有效地处理交易。而现有银行的系统是由中央机构控制的，它们受到政府的监管，并且在处理交易方面存在一定的延迟。

区块链的安全性也是值得称道的。它采用了公钥加密技术，可以有效保护用户的隐私，并且可以防止网络攻击。而现有银行的安全性却没有得到很好的保障，它们经常会受到黑客的攻击，从而导致用户的隐私泄露。

总之，区块链与现有银行的关系和区别，主要体现在去中心化、自治性和安全性三个方面。区块链技术的出现，为网络上的货币交易提供了一种新的可能性，也为金融服务提供了新的发展机遇。

㈠ How to apply blockchain technology in bank international settlement

At this stage, banks mainly provide three settlement methods: remittance, collection and letter of credit in international business. There are problems of credit and exchange rate risks, low efficiency, and high costs. In addition, banks mostly use their own credit to intervene in international settlements, which can easily form their own contingent liabilities and reduce the quality of their balance sheets. Banks should actively promote innovation in international settlement business based on blockchain technology, build a new system for international settlement business, and provide safe, stable, low-cost, and efficient international settlement business.

㈡ Why do banks love blockchain so much

Many problems remain to be solved when banks compete for blockchain

As traditional financial institutions, banks are blockchain The most active pathfinder in the field. In recent years, many domestic and foreign banks have applied blockchain technology to credit, clearing and other fields. The unique trust mechanism of blockchain is regarded by banks as a key technological breakthrough for innovative risk management and simplified transaction processes. However, as an emerging technology, the blockchain ecosystem is still in the process of being established, its applications are very limited, and many problems still need to be gradually solved during development.

“At present, the blockchain cannot run high-frequency and concurrent transactions, and the network speed and computing power cannot support it. For example, in the payment field, if it is online shopping, it can still be achieved; if It’s high-frequency trading in futures, so it can’t be done,” Huang Zhen said.

Jiang Peng said that at the beginning of designing the blockchain system, CITIC Bank carefully demonstrated the business links suitable for using blockchain.

“From global experience, it is not suitable to use blockchain to build large and complex systems. Don’t try to use blockchain to solve all problems, but focus on solving core problems. Do too much Complex systems are time-consuming, and technology develops so fast that before the old system is completed, it will face iterations of new technologies," Jiang Peng said.

The idea of ​​"only solving core problems" ensures that after the blockchain is launched, the relevant business operations of CITIC Bank branches can achieve business upgrades without process modification.

Fan Bin admitted that it will take time for banks to fully apply blockchain. IBM's investment in the blockchain open source community will continue, on the one hand, to cultivate the market, and on the other hand, to compete for blocks. The commanding heights of the chain platform. With the rapid iteration of blockchain technology itself, there is still a lot of room for imagination in the scenarios in which financial institutions can use this new technology.

㈢ How is blockchain technology used in the banking industry

The biggest feature of blockchain technology is decentralization. This feature will reduce a lot of costs for the banking industry.

First of all, decentralization means that intermediaries are no longer needed to establish a trust mechanism between banking systems, saving intermediary costs.

Secondly, the development of digital currency will make it possible to realize real-time digital transactions in banks. For example, in bill transactions, banks have always relied on third parties to transfer valuable certificates.Even if it is an electronic bill transaction, it needs to pass the information of the central bank's ECDS system for interactive authentication. Blockchain technology can realize point-to-point transfer of value and no longer requires centralized system control. This not only speeds up the speed of ticket transfer, but more importantly, it can reduce errors caused by human factors and reduce processes. Naturally, it will reduce the bank's demand for personnel and save the bank's labor costs.

Finally, it will also have an impact on clearing and settlement. The bank's clearing and settlement business has always been completed by central clearing, which is inefficient. Settlement through blockchain technology will greatly improve the efficiency of banks.

Blockchain technology also plays a major role in banks’ cross-border payment services. Today, when global trade is highly developed, cross-border payments are becoming more and more frequent, and banks often act as third-party services in cross-border trade, such as electronic transfers, asset custody, etc. However, cross-border payments generally take about 2 days to arrive, which is very inefficient and reduces the utilization of funds in transit. In blockchain technology, both parties of cross-border payments can be completed in a point-to-point manner, achieving round-the-clock payment and real-time arrival, thereby speeding up clearing and settlement, thereby improving the efficiency of bank processing business.

Another feature of blockchain technology is de-risking. Banks can build their own blockchain, which can ensure that bank customers’ transaction information and transaction records are true and valid and will not be compromised. Without any tampering, the bank can effectively identify the customer's information, understand all aspects of the customer's situation, identify the customer's abnormal transactions, and prevent being deceived by the customer, thus reducing the bank's supervision costs.

㈣ Application of blockchain in the financial field

1. Application and development of blockchain

Some Internet, Internet start-ups and traditional financial industries Started to try out applications in some projects

2. Domestic financial institutions are testing the waters of blockchain

Various financial institutions are testing the waters one after another, and they are basically in the conceptual experimental stage and have not yet reached a large scale. Commercial scale.

3. Panoramic view of blockchain application in the financial field

4. Ghostwriting

5. Digital bills

Bills are an important financial product in the financial market. They have dual functions of payment and financing. They are of high value and bear bank credit or commercial credit. Once a bill is issued, its face amount, date and other important information cannot be changed.Bills also have circulation attributes and can be accepted, endorsed, discounted, rediscounted, collected and other transactions within a specific life cycle. Once the transaction is completed, the transaction cannot be revoked. There are two characteristics in the circulation of bills: First, the circulation of bills mainly occurs through bank acceptance bills, and the number and circulation of commercial acceptance bills are small; second, each bank independently conducts credit granting and risk control on the bill business, and a single bank's Risk control results may affect other participants in the bill market transaction chain.

The experimental production system of the digital bill trading platform uses SDC (Smart Draft Chain) blockchain technology to protect privacy through cryptographic algorithms such as homomorphic encryption and zero-knowledge proof. The Byzantine Fault Tolerance Protocol (PBFT) performs consensus and uses a see-through mechanism to provide data monitoring.

The experimental production system includes four subsystems: stock exchange, bank, enterprise and monitoring: the stock exchange subsystem is responsible for managing the blockchain and monitoring the digital bill business; the bank subsystem has Digital bills have business functions such as acceptance and receipt, discount signing, rediscounting, and collection and repayment; the enterprise subsystem has business functions such as issuance, acceptance, endorsement, discounting, and prompt payment of digital bills; the monitoring subsystem monitors the status of the blockchain in real time and business occurrences

㈤ Blockchain companies cooperate with central banks of many countries to develop CBDC. It is possible for central bank digital currencies to adopt blockchain

As we all know, The legal digital renminbi uses a centralized ledger based on the UTXO model, which is maintained and managed by the People's Bank of China. This is incompatible with blockchain technology, which uses decentralized distributed ledgers as one of its core mechanisms. The use of blockchain technology advantages by blockchain technology companies to participate in the central bank digital currency (CBDC) is a new breakthrough and new application of blockchain technology.

ConsenSys participates in CBDC research and development

It is reported that ConsenSys has released the "Blockchain Solution for Central Bank Digital Currency (CBDC)" on its official website. The article stated that digital currency can provide Cheaper cross-border remittances, improved inter-bank payment settlement and accelerated retail market innovation, etc. If central banks do not issue their own digital currencies, it will lead to markets relying on "private payment tokens", potentially creating a risk of failure and financial problems for private entities, as private tokens may not be available to everyone, Central bank digital currencies will bring risk-free, widely used alternatives.

Charles d'Haussy said that in 2016, ConsenSys began to engage in relevant work on CBDC through cooperation with the Singapore Monetary Authority and the South African Reserve Bank, and has graduallyCross-border payment technology business has been gradually developed. "Building on this, we are exploring a larger concept - 'programmable money', which any CBDC with a token architecture can support. CBDC is a perfect iteration of electronic cash that can improve the utilization of central bank funds efficiency, ensuring a more efficient value chain.”

In addition, ConsenSys recently released a compliance service to help exchanges and decentralized finance (DeFi) projects identify possible issues related to Ethereum issuance. Token trading activity related to criminal activity. Lex Sokolin, co-head of global fintech at ConsenSys, said, “More and more people are building decentralized applications, which is part of the puzzle. What we are trying to do is make activities on decentralized financial infrastructure more Safe, transparent and easier to track."

With its strong blockchain technology background, ConsenSys has participated in the research and development of central bank digital currencies in countries such as Australia, France and Thailand, which may integrate blockchain technology with CBDC become possible.

The feasibility of using blockchain technology for CBDC

Regarding the question of whether blockchain, which features a decentralized distributed ledger, can be combined with a centralized central bank digital currency Yao Qian, director of the Science and Technology Supervision Bureau of the China Securities Regulatory Commission, pointed out that whether CBDC adopts blockchain technology is still controversial. A typical view is that the decentralization of blockchain conflicts with the centralized management of the central bank, and it is not recommended for CBDC to adopt it. The technology.

However, blockchain technology is developing at an unprecedented speed and is deeply integrated with various mainstream technologies. Therefore, no matter from a technical perspective or a business perspective, the blockchain in real applications is in line with the "original teachings". The understanding of "ism" is different. How to use blockchain technology to better serve distributed operations under centralized management may be the current direction that CBDC needs to focus on exploring.

Yao Qian believes that although the technical characteristic of blockchain is that it does not rely on central institutions, it does not mean that it cannot be incorporated into the system of existing central institutions. As long as it is properly designed, the central bank can just use it Blockchain effectively integrates distributed operations and better realizes centralized management and control of CBDC. There is no inevitable conflict between the two. As an emerging technology that may become the future financial infrastructure, blockchain helps achieve distributed operations without affecting centralized management for the dual model of central banks and commercial banks. Bottom-up "exchange" can formulate a new CBDC implementation plan, which also achieves the goal of "centralized management and control, distributed operation".

A digital currency research project announced by the Reserve Bank of Australia is exploring the potential use and impact of a central bank digital currency (CBDC) using distributed ledger technology (DLT).

Under this project, Australia will develop a form of issuing tokens.A proof of concept for a CBDC that market participants will be able to use for financing, settlement and repayment of tokenized syndicated loans on an Ethereum-based DLT platform. The project is expected to be completed around the end of 2020, and various project participants plan to release a thematic report on the project and its key findings in the first half of 2021.

㈥ What are the practical applications of blockchain in China

1. WeBank uses blockchain technology for loan settlement

With the introduction of this blockchain system, all information is recorded on the blockchain network and cannot be tampered with. It is liquidated simultaneously during the transaction process, achieving real-time liquidation and saving a lot of manpower and material resources. This is the practical application of "consortium chain".

2. China UnionPay uses blockchain technology to realize inter-bank point redemption
China UnionPay and IBM are trialling a shared points system using blockchain technology. The use of this blockchain system allows users to redeem reward points across banks and platforms. That is to say, a user's points in one bank can be exchanged for points and rewards from other banks, or even multiple airline miles and supermarket rewards. The efficiency of using bank points has been greatly improved.
3. Toyota Motor uses blockchain technology to track auto parts
Toyota Motor joins the R3 Alliance and uses blockchain technology to store the production, processing and usage of each part in the blockchain. In this way, when there is a problem with a car part, the source of the part can be easily and quickly found.
4. Central Bank’s Blockchain Digital Bill Trading Platform
The blockchain-based digital bill trading platform promoted by the Central Bank was successfully tested. The introduction of digital currency for settlement can realize the simultaneous transfer of capital flow and information flow in digital bill transactions, thereby realizing DVP pay-versus-payment settlement. At the same time, the blockchain digital identity solution solves the problem of repeated KYC authentication for users between different financial institutions.

㈦ What is the relationship between blockchain technology and the financial industry

Blockchain technology has the advantages of being difficult to tamper with and easy to trace.It can play a role in identity information management, trust mechanism construction, and small and micro enterprise credit information chain integration.

Here we can give an example of a bank in Nanping:

Due to the explosion of online business, the original offline signing method can no longer satisfy the bank. With the demand for rapid business changes, the digital construction of banks is urgent, but bank risk control departments have strict compliance requirements:

Is the online business data sensitive and private, and is the transmission safe?

Does electronic signature have legal effect?

Is electronic evidence admissible in court?

These concerns have become obstacles for banks to introduce electronic contracts and carry out digital transformation of their businesses.

After adopting the unique ENA active evidence collection patented technology of the "Real Hammer" trusted electronic evidence platform, a bank in Nanping used the notary office to clean the server to preserve and store the electronic data of the target system online in real time. With the issuance of certificates, the entire process of electronic data from generation, transmission to storage is recorded. Finally, the notary office issues an evidence collection and preservation report stamped with the official seal. The document is a notarized document and can be directly accepted by the court. Since the report is issued by the notary public office, it is relevant. It is more credible than the self-certification of third-party electronic contract platforms. It solves the concerns of bank risk control departments in one fell swoop. The entire process is online and automated, and front-end customer operations are imperceptible.

At the same time, combined with the "real hammer" middle and back-end case-like system and outsourced execution services, the bank has achieved rapid dispute resolution in Internet business. It not only ensures the compliance and effectiveness of the electronic contract signing process, but also solves the problems of bank cases being scattered across the country, high legal travel costs, long litigation cycles, and no efficient disposal channel.
