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 happenings

4. What are the application prospects of blockchain?

The application prospects of blockchain are mainly in the financial field, the Internet of Things and logistics, public services, digital copyright, and insurance. .

1. Blockchain has huge potential application prospects in financial fields such as international exchange, letters of credit, equity registration and stock exchanges. The application of blockchain technology in the financial industry can eliminate the need for third-party intermediaries and achieve direct point-to-point connection.

2. Blockchain can also be naturally combined in the field of Internet of Things and logistics. This field is considered to be a very important area of ​​blockchain.Prospective application directions. Establishing credit resources in the blockchain can double improve the security of transactions and improve the convenience of IoT transactions. Save time and cost for smart logistics model applications.

3. Blockchain is closely related to people’s production and life in public management, energy, transportation and other fields. The decentralized and fully distributed DNS service provided by the blockchain can realize domain name query and resolution through point-to-point data transmission services between various nodes in the network.

4. Through blockchain technology, works can be authenticated, proving the existence of text, video, audio and other works, and ensuring the authenticity and uniqueness of ownership.

The core technology of block chain

1. The consensus mechanism completes the verification and confirmation of transactions in a short period of time through the voting of special nodes; for a transaction, if several nodes with unrelated interests can reach a consensus, it can be considered that the entire network can also reach a consensus on it. consensus. The goal of the blockchain consensus mechanism is to enable all honest nodes to maintain a consistent view of the blockchain.

2. Asymmetric encryption requires two keys for encryption and decryption. These two keys are the public key and the private key. The public key corresponds to the private key. When the public key is used in the encryption process of data, it can only be decrypted by using the corresponding private key. On the contrary, when the private key is used in encrypting the data, only the corresponding private key can be used to decrypt the data. Only the corresponding public key can be decrypted.

5. What is blockchain technology and how does it change business and financial models

Blockchain technology is a distributed ledger technology that Allows multiple participants to jointly maintain a secure, transparent and immutable record on a decentralized network. Blockchain technology was originally designed for the digital currency Bitcoin, but is now widely used in many other fields.

The core features of blockchain technology include:

Decentralization: Blockchain has no central control agency, and data is distributed on various nodes in the network, which makes it decentralized. The centralization feature reduces the risk of single points of failure.

Transparency: Transaction records on the blockchain are public to all participants, and anyone can view these records. This helps increase trust and reduce the risk of fraud.

Immutable: Once a transaction is recorded on the blockchain, it cannot be easily modified or deleted. This guarantees data integrity and security.

Smart contracts: Transactions on the blockchain can be automatically executed to implement "smart contracts", which automatically execute corresponding operations when specific conditions are met. This helps simplify complex business processes and reduce costs.

Blockchain technology has had a profound impact on business and financial models, which is mainly reflected in the following aspects:

Reducing costs: Blockchain technology can reduce intermediary links and reduce costs. Transaction costs and operating costs. For example, by adopting blockchain for cross-border payments, remittance fees can be significantly reduced.

Improving efficiency: The automation and smart contract features of blockchain technology help improve the efficiency of business processes, reduce manual intervention, and reduce error rates.

Enhance trust: The transparency and non-tamperability of blockchain technology help to establish a reliable trust system, reduce the risk of fraud, and provide better protection for commercial activities.

Innovative business models: Blockchain technology has spawned many new business models, such as decentralized finance (DeFi), digital asset trading, supply chain finance, etc. These new business models have brought disruptive changes to existing industries.

In short, blockchain technology, as an emerging technical means, is gradually changing the landscape of business and finance. With the continuous development of technology and the in-depth promotion of applications, blockchain is expected to have a more extensive and far-reaching impact in the future

6. Blockchain: the next trend in the financial industry

When it comes to blockchain technology, people may feel unfamiliar. But if you understand its origins with the famous Bitcoin, you will suddenly understand. Broadly speaking, Bitcoin is actually the first successful application of blockchain technology. We know that money is the intermediary that completes transactions. Over the past few centuries, as the frequency and complexity of transactions have continued to increase, these complex transaction records, or ledgers, are held by different entities and are isolated from each other, making the transaction information in them inaccessible to the public. Therefore, in order to complete the transaction, a trusted third party or intermediary needs to be involved between the buyer and the seller, and the human investment and cost are also greatly increased. For example, governments, banks, notaries and various banknotes all play this role. Only if they exist can we trust the other party to the transaction.

Bitcoin is a decentralized currency that bypasses intermediaries and enables peer-to-peer exchange of value. The principle of Bitcoin is to distribute account books to each transaction participant through the encryption technology of the blockchain. Each account book is like the genes of a living thing - the individual participants are different, but the contents of their account books are completely consistent. Once any transaction occurs in the network, corresponding records will be generated in the account books of all participants. Once someone attempts to hack and modify a single ledger, all other ledgers automatically detect the fraud.

Miners are like gene replicators and disseminators. Their role is to verify transactions and ensure the consistency of distributed ledgers. Therefore, the emergence of Bitcoin or blockchain technology completely solves the problem of transaction fraud and credit fraud.The issue of information opacity. Imagine you want to buy a second-hand house. It will take you several days to verify and notarize the quality and mortgage status of the house and complete the transaction, during which multiple institutions and individuals are involved. Blockchain technology can complete these tasks within minutes, greatly reducing human labor and costs. In addition to transactions and payments, blockchain technology has other rich application scenarios.

To give a simple example, how can a supermarket selling organic food ensure that its supplies are all organically produced, non-GMO food? In the past, supermarkets had to spend a lot of manpower and material resources to ensure the reliability of supply, and this statement was not foolproof because you could not prevent fraud from unscrupulous merchants. With the distributed accounting of blockchain technology, from farms to suppliers to logistics, the time, quantity and amount of each transaction are clear. With this information guarantee, supermarkets will have more confidence when conducting marketing. Therefore, Boston Consulting believes that blockchain technology has the potential to subvert the current credit system and transaction system.

This is just one of the most basic applications of blockchain technology: asset and identity management. In the financial industry, blockchain technology can simplify and accelerate financial processes and settle various real-world financial transactions through distributed accounting without third-party certification. In the future, we may even see the emergence of so-called coded and encrypted smart contracts, allowing stocks to become digital records that can be issued and traded on the Internet, significantly reducing transaction costs. Digital stock trading systems can make it easier for small and medium-sized enterprises to raise funds from the public. , and the cost is lower.

Therefore, although the first application of blockchain technology, Bitcoin (Encryption 1.0), has been subject to many restrictions such as regulatory issues. However, the application of blockchain technology in other fields, such as distributed accounting, payment settlement and smart contracts (encryption 2.0), has been recognized and highly valued by regulatory and financial institutions in various countries. Regardless of the future of Bitcoin, blockchain technology will become a very important innovation in the financial industry in the near future.

1. Venture capital helps blockchain technology take off

There are currently more than 750 innovative companies related to blockchain technology in the world. About 200 of them have received venture capital, and their businesses can be divided into the following six main application areas: digital currency, payment and settlement, smart contracts, asset and identity management, infrastructure and open source development, as well as venture capital, media and consult.

From the investment stage, blockchain technology is obviously in its infancy. Among the 200 companies that received capital injection, 124 received seed investment, only 49 companies achieved Series A financing, 12 companies achieved Series B financing, and only 4 companies received Series C financing. In terms of investment amount, more than two-thirds of the financing is in the seed and Series A stages.

2. New opportunities for financial institutions

Although it is still in its infancy, compared with technologies in other fields, financial institutions haveThe response to blockchain technology has been even more positive. For example, Nasdaq is collaborating with the startup Chain to explore new ways of issuing stocks. Traditional securities issuance methods are expensive, require a lot of labor, involve many institutions and stakeholders, and there is a lot of room for improvement. Nasdaq announced that it will apply the blockchain technology provided by Chain to the "NASDAQ Private Market", an equity trading platform for unlisted companies, becoming the first to issue and transfer private equity through blockchain technology. A financial institution that holds a share of a company's stock. Nasdaq Chief Executive Officer (CEO) Bob Greifeld said: "As blockchain continues to reshape the global economy, Nasdaq wants to be at the center of the event."

The San Francisco digital payment company (Ripple Lab), founded in 2012, focuses on the development of payment protocols. It has now become the main cryptocurrency system after Bitcoin and Ethereum. Through the open source Internet encryption protocol and distributed accounting mechanism, financial institutions can make fast and secure payments through Ripple. Several major banks have purchased authorizations for the Ripple protocol, playing a huge role in currency exchange and remittance.

7. CreditEase Puhui: Promoting the normalized application of blockchain technology and empowering the development of financial technology

Recently, it was pointed out in the “14th Five-Year Plan” outline that it is necessary to comprehensively Promote innovation in blockchain technologies such as smart contracts, consensus algorithms, encryption algorithms, and distributed systems, focus on alliance chains to develop blockchain service platforms and application solutions in areas such as financial technology, supply chain management, and government services, and improve regulatory mechanisms.

It can be seen that blockchain application innovation has officially become one of the national strategies and will definitely have a significant impact on the financial industry. Under such a situation, financial institutions are accelerating blockchain-related exploration and promoting blockchain technology to play a greater role in the financial field. Next, follow CreditEase Puhui to learn about blockchain-related knowledge!

What is blockchain

Blockchain is a chained data structure that combines data blocks in a specific order in chronological order. Records of all transactions since the birth of the system are stored. The data on the blockchain is jointly maintained and stored by nodes throughout the network, and cryptography ensures that the block data cannot be tampered with or forged. So the blockchain is essentially a distributed shared database.

Blockchain is an innovative application model of computer technologies such as distributed data storage, point-to-point transmission, consensus mechanisms, and encryption algorithms in the Internet era. It is an information technology solution that solves trust problems and reduces trust costs. . The application of blockchain technology can eliminate traditional trust intermediaries, subvert the old centralized model that has existed for thousands of years, and eliminate the need for centralized trust.In the case of introduction, it solves the trust problem between strangers and greatly reduces the cost of trust.

How blockchain can solve the pain points of supply chain finance

Supply chain finance is based on core customers, based on real trade background, and uses self-reimbursement trade financing. , which provides comprehensive financial products and services to upstream and downstream enterprises in the supply chain through professional means such as accounts receivable pledge registration and third-party supervision to close capital flows or control property rights.

The foundation of supply chain finance is the supply chain. The supply chain involves information flow, capital flow, logistics and business flow, and is naturally a multi-subject and multi-collaboration business model. In this case, if you want to carry out trade financing, you will first encounter many authenticity issues, such as the authenticity of the transaction and the authenticity of the documents, which require confirmation by multiple parties and consume a lot of manpower and material resources; secondly, the multiple entities involved , there is a problem of difficulty in interconnection. For example, the supply chain management system, enterprise resource management system, and even financial system used by each entity are different, making docking difficult. Even if they are connected, it will be difficult to share information due to inconsistent data formats and data dictionaries.

Characteristics of blockchain

1. Decentralization

The distributed structure of blockchain means that data is not recorded and stored in the center. Instead of using a dedicated computer or host, each node participating in the data transaction records and stores all data information. To this end, the blockchain system uses an open source, decentralized protocol to ensure complete recording and storage of data. The blockchain has built a complete set of protocol mechanisms, allowing each node in the entire network to participate in recording data while also participating in verifying the correctness of the recording results of other nodes. Only when most nodes (or even all nodes) in the entire network confirm the correctness of the record will the data be written into the block. In the distributed structure network system of the blockchain, the network nodes participating in the recording will update and store all data in the entire network system in real time. Therefore, even if some nodes are attacked or destroyed, the data update and storage of this system will not be affected.

2. Unforgeable

The principle of blockchain recording requires all nodes participating in the recording to jointly verify the correctness of the transaction record. Since all nodes are recording every transaction in the entire network, once the information recorded by a node does not match that of other nodes, other nodes will not recognize the record, and the record will not be written into the block.

3. Non-tampering

It is almost impossible to change a certain block and the transaction information within the block. If this block is changed, every subsequent block will be changed. Therefore, anyone trying to tamper with data must simultaneously invade at least 51% of the nodes participating in the global record and tamper with the data..

Mathematical encryption

Each transaction requires a valid signature before it will be stored in the block. Only valid digital keys can generate valid signatures. Keys come in pairs and consist of a private key and a public key. Among them, the public key is public, and the private key is only visible and used by the owner, and is used for transaction signatures to prove digital identity.

What are the advantages of introducing blockchain?

First, to solve the problem of information islands, multiple stakeholders can set rules in advance to accelerate data interoperability and information sharing;

Second, according to property rights law , Electronic Contract Law, Electronic Signature Law, etc., the accounts receivable certificates of core enterprises can be converted into transferable and bankable confirmation certificates through the blockchain, so that the credit of core enterprises can be transmitted along trusted trade links. Based on mutual confirmation, the entire certificate can derive various operations such as splitting and traceability;

Third, provide credible trade data, such as providing an online basis under the blockchain architecture Tightly structured and complete records of contracts, documents, payments, etc. improve information transparency and achieve penetrable supervision;

Fourth, achieve cost reduction and efficiency improvement. After the credit of the core enterprise is transferred, small and medium-sized enterprises can use the credit line of the core enterprise to reduce financing costs and improve financing efficiency;

Fifth, realize smart liquidation of contracts. Automatic clearing and settlement based on smart contracts reduces manual intervention, reduces operational risks, and ensures the safety of repayment.

CreditEase Puhui believes that blockchain supports commercial applications with high performance, high scalability, and high security, provides financial technology companies with multi-level data security and privacy protection, and supports automatic monitoring and failure Alerts help track all transactions that occur in the system and contribute to the healthy and orderly development of the financial technology industry.

8. What are the prospects of blockchain finance?

1. In fact, the combination of blockchain technology and finance is not accidental. Simply put, blockchain is a distributed shared ledger and database, which has the characteristics of decentralization, non-tampering, full traceability, and traceability. Finance is cooperation based on trust, and these characteristics of blockchain lay the foundation for creating trust. Blockchain technology is of great significance in solving problems in the financial field such as high credit risk, low capital utilization efficiency, and high payment processing costs.
2. In reality, Bitcoin is not equal to blockchain. Digital currency is just one of the applications of blockchain technology in the financial field. In the fields of supply chain finance, payment and clearing, trade finance, financial transactions and other fields, "blockchain +" has rich application scenarios and imagination space.
3. Industry insiders pointed out that although the application prospects of blockchain technology are broad, Projects that are currently being implemented and producing social benefitsThe number is small, and blockchain technology is in its early stages of development and still needs to be viewed rationally. In the next step, blockchain technology should be used to explore digital economic model innovation, add impetus to the optimization of the business environment, and provide support for promoting high-quality economic development.
