⑴ FISCO - Golden Chain Alliance creates a new era of public alliance chain

Public chain, alliance chain (permission chain) and private chain can be said to basically include blockchain Three ways to use technology. In recent years, the planning, financing, development and ecological construction of the public chain can be said to have been carried out in a noisy manner. Some are real, and there are even more deceptions. It is noisy, noisy, muddy and sandy, and investors' money has really gone in. But not many are online, and the ecological construction of the few public chains that are online is also sparse. There are very few DApps, and the daily activity is even less. In short, not many current public chain projects can or are willing to survive. Ecological construction is even further away.

Private chains are self-built and internally run blockchain architectures of respective companies and institutions. Very little information is disclosed, but I believe that using your own money to do your own things and solve your own problems will not cause any problems. What a big deal.

The development of the alliance chain has always been low-key. Since blockchain technology was recognized by the mainstream economy and society, pragmatic mainstream economic institutions have been solidly carrying out research, development and application for about 4 years. During this period, the backbone of the alliance chain was formed, and another correct path was found for the implementation of blockchain applications and ecological construction. In a certain sense, the alliance chain has passed its infancy and has begun to solidly move towards the "public alliance chain" new era. The alliance chain's naturally strong relationship with mainstream economic industry resources also determines the alliance chain's mainstream status in the application prospects of blockchain technology.

With the dawn of the digital economy era and the popularization of distributed business models, blockchain technology has also been able to give full play to its advantages and become a representative of cutting-edge technology. In 2016, three companies, WeBank, a member of the Golden Link Alliance, Shanghai Wanxiang Blockchain, and Matrix Yuan, a member of Chinaledger, reached a strategic cooperation and jointly committed to exploring blockchain technology, and

The full name of Golden Link Alliance is Financial Blockchain Cooperation Alliance (Shenzhen). It was jointly established on May 31, 2016 by more than 20 financial institutions and technology companies including Shenzhen Financial Technology Association, Shenzhen Qianhai WeBank, and Shenzhen Securities Co., Ltd. Non-profit organization established. As an open organization, Financial Institutions that voluntarily abide by the charter and companies that provide technological services to financial institutions can apply to join. So far, members of the Golden Link Alliance include more than 80 institutions in six major industries including banks, funds, securities, insurance, local equity exchanges, and technology companies.

On November 26, 2016, Golden Chain Alliance released the "Financial Distributed Ledger Proposal", proposing five major principles such as legal compliance, traceability, security, privacy protection, and business orientation, as well as a value alliance , autonomous and controllable, safe and trustworthy, efficient and available, business feasible, flexible configuration, intelligent supervision and other seven propositions.

Purpose: Integrate and coordinate financial blockchain technologyResearch resources, form a synergy and coordination mechanism for financial blockchain technology research and application research, improve the research and development capabilities of member units in the field of blockchain technology, explore, develop, and implement financial alliance blockchain suitable for financial institutions, and application scenarios based on this.

The General Assembly of the Golden Chain Alliance is the highest authority; the permanent body of the General Assembly is the Presidium, which leads the alliance to carry out daily work during the intersessions of the General Assembly and is responsible to the General Assembly; the Presidium has a technical committee (chaired by Application project work), Standards Technical Working Committee (presides over the establishment, formulation, review and release of standards), Advisory Committee (organizes external experts to participate in technical and standards discussions).

Jinlianmeng has set up research directions in the fields of credit, equity, points, insurance, bills, cloud services, digital assets, financial product issuance and trading, and some of the projects have now been implemented or products have been launched. prototype.

The FISCO BCOS underlying blockchain platform is jointly built by the FISCO open source working group. Members of the working group include Beyondsoft, Huawei, Shenzhen Securities Exchange, Digital China, Sifang Innovative, Tencent, WeBank and Yuexiu Jinke and other members of the Golden Link Alliance, aiming to create a secure and controllable blockchain suitable for the financial field. The underlying platform of the chain.

Financial services are one of the earliest application areas of blockchain. Blockchain technology brings advantages such as safety and reliability, simplified processes, cost savings, reduced operational risks, and increased trust, and has the potential to reconstruct and sublimate the original financial industry infrastructure. The financial industry focuses on multi-party reciprocal cooperation and has strong supervision and high-level security requirements, which require node access and authority management. Therefore, the technical direction of the alliance chain has become the main choice for the financial industry.

At present, my country's financial industry is opening up to the outside world with unprecedented intensity, and the pace of financial innovation is also accelerating. Therefore, how to effectively balance the relationship between open innovation and risk prevention and firmly maintain the bottom line of no systemic risks is an important issue for the industry. challenges that urgently need to be addressed.

From the perspective of financial IT infrastructure, there are still some shortcomings and pain points in operational risks, moral hazards, credit risks, information protection risks, etc.

First, financial IT system data may still be tampered with, forged, or have consistency differences.

Second, the infrastructure structures and business processes of different financial institutions are different, and even still involve many manual processes, which greatly increases operating costs and is also prone to operational risks and ethics. risk.

Third, financial business and financial cooperation may involve multiple participants or intermediaries, which can easily increase trust costs and friction costs. There is also a certain degree of mutual trust and collaboration.or cooperative equivalence issues.

Fourth, financial business is often highly complex, and it is easy to miss records of all business elements. Sometimes it is difficult to trace the entire business process, and it cannot meet the needs of supervision and auditing.

Fifth, the data between different financial institutions are relatively independent, making it difficult to achieve safe and efficient interaction, resulting in high costs for repeated KYC, anti-money laundering, and anti-fraud, and also indirectly causing the loss of user data. Risk of being leaked by certain intermediaries.

Sixth, the availability and adaptability of centralized IT infrastructure are weak, and distributed technologies need to be used to improve robustness or adaptability.

As a combined infrastructure solution, blockchain technology can in principle respond to the needs of the financial industry. However, because the requirements of the financial industry are more diverse and strict, as a financial version of the blockchain solution, it needs to be based on the blockchain technology of the universal industry and according to the special business needs of financial institutions, existing technical levels, and laws and regulations. Requirements or conditions in other aspects shall be comprehensively considered from multiple dimensions such as business suitability, performance, security, policy, technical feasibility, operation and maintenance and governance, and cost.

First, the appropriateness of the business scenario. Not all financial business scenarios require the use of blockchain technology. Generally speaking, when it comes to scenarios involving multi-party participation and peer-to-peer cooperation, the traditional centralized system architecture is often difficult to meet the needs, so you can consider using blockchain technology. This will increase multi-party mutual trust, improve business operation efficiency, and reduce business operation costs and friction costs.

Second, the performance of the blockchain system. Financial business often has characteristics such as massive transactions, high-frequency transactions, and timely confirmation. Therefore, the blockchain open source platform in the financial industry needs to analyze the business volume, potential business growth scale, and potential business growth scale that the blockchain system needs to support based on the current business scale of financial institutions. Technical performance index requirements such as concurrent business volume and response time. Since blockchain platforms using different technical modules, such as different consensus mechanisms, have greatly different performance support, it needs to be evaluated based on business performance requirements and combined with blockchain performance efficiency indicators.

Third, the security of the blockchain system. Blockchain can ensure the credibility of recorded data from a technical level and prevent data from being tampered with, forged and other risks. In addition, in terms of data sensitivity and security, it is necessary to evaluate the content encryption strength of the on-chain data, as well as access control, etc. Financial institutions need to choose mature, appropriate, and secure encryption algorithms based on the specific security requirements of their business.

Fourth, policy compliance. Blockchain is a set of technical solutions that, with reasonable design, can provide good support for existing businesses or complement existing centralized systems. However, when financial institutions use blockchain to conduct business, they must implement it within the country's existing regulatory requirements and legal framework.

Fifth, technical feasibility. Blockchain technology has already been implemented in some financial scenarios, but it is still an emerging technology. It is necessary to fully evaluate the fit of the technology with specific businesses and its advantages and disadvantages compared with traditional systems before finally choosing the appropriate area. Demonstration and trial operation of the blockchain platform.

Sixth, operation and maintenance and governance capabilities. Since there are differences in operations and management between blockchain-based businesses and traditional centralized systems, and the continuous governance requirements of financial businesses are extremely high, corresponding planning and adjustments are required to evaluate the feasibility and sustainability of the new governance structure. , evaluate the impact of version iterations and the official launch of the system, monitor the operation of the blockchain system in real time, and ensure business controllability and financial environment stability.

Seventh, costs are controllable and economically feasible. Blockchain applications use technical features to solve specific problems in actual business. Applications that effectively solve pain point problems can bring great benefits to financial businesses, and the value of the application itself can also be revealed; on the contrary, if it cannot solve important problems in the industry , you need to face a trade-off between costs and benefits.

If a safe and reliable underlying financial blockchain platform can be built to meet the special needs of the financial industry, blockchain technology will be of great use in the financial industry.

For example, from the perspective of banking institutions, the key exploration directions are generally to apply blockchain technology to reduce clearing and settlement costs, improve middle and back-office operational efficiency, improve process automation, and reduce operating costs. In addition, in cross-border financial scenarios, blockchain can help realize ledger sharing among cross-border financial institutions, reduce reconciliation and settlement costs and dispute friction costs between cooperative banks, thereby improving the processing speed of cross-border business. and efficiency.

From the perspective of non-bank financial institutions, blockchain can be used to improve the authority of rights registration and information storage, reduce counterparty risks, solve data tracking and information anti-counterfeiting issues, and reduce audits. operating costs, etc.

From the perspective of financial regulators, blockchain provides regulators with consistent and easy-to-audit data. Through data analysis of inter-institutional blockchains, the audit process can be faster and more efficient than traditional audit processes. Precisely regulate financial operations. For example, in an anti-money laundering scenario, the balance and transaction records of each account are traceable, and no aspect of any transaction will be out of sight of supervision, which will greatly strengthen anti-money laundering efforts.

Designed an efficient, reliable, message communication protocol based on the blockchain network, referred to as Advanced Messenger On-chain Protocol AMOP (Advanced Messenger On-chain Protocol), focusing on the following functions:

 Based on the blockchain network, it supports inter-bank and point-to-point real-time message communication;

 Provide standardized interfaces for the interaction between off-chain systems and blockchain;

 The blockchain system can actively call the business interface of the off-chain system;

The technical characteristics of this protocol are:

 In a point-to-point blockchain network topology, plan node communication paths to ensure message reachability;

 It can quickly sense node abnormalities in the blockchain network and automatically switch paths to resend messages;

 Use encryption technology during the communication process to ensure privacy at the communication layer.

Designed the contract naming service CNS (Contract Name Service). The design goal of CNS is to name the correspondence between the business layer and smart contracts, so that the business layer no longer cares about the relevant contract addresses. Similar to DNS on the Internet, the use of domain names makes it easier for users to remember how to access a website, and also gives the website great flexibility in terms of clustering, migration and expansion.

At present, ODRChain has shortened the time it takes for customers to go from clicking "one-click arbitration" to receiving the arbitration award, from the traditional arbitration process that lasted several months to about 7 days. , and the arbitration fees that originally cost tens of thousands of dollars have been reduced to a few hundred yuan. As of December 2018, ODRChain has completed the deposit of over 10 million contracts, involving hundreds of billions of funds.

First prize: JustSign - a white-box cryptographic algorithm that turns a mobile phone into a USB shield

The project that grabs the first prize in the competition - JustSign, is based on FISCO BOCS It is an electronic contract signing and certificate storage system. Its original JustKey white-box cryptographic algorithm realizes "mobile phone as USB shield", which solves the problem of limited compatibility of traditional CA, inability to protect key security on the mobile terminal, and vulnerability to attacks in centralized data storage. question.

Expert reviewers commented that electronic contracts involve complex legal relationships and ownership of interests, and it has long been difficult to achieve a balance between security, integrity and portability. The team’s original white-box cryptographic algorithm is really conducive to improving security in blockchain certificate storage scenarios.

Second Prize: Internet of Things Trusted Interconnection Solution - The Picture of Smart Life Looks Like This

The Internet of Things Trusted Interconnection Solution competed by Sichuan Changhong Security Laboratory depicts Come up with a smart home blueprint that requires almost no extra worry on your part. When analyzing the blockchain technology behind it, a team representative said that an inter-enterprise cooperation alliance is established based on the alliance chain to open up the interconnection and mutual trust of IoT devices between different manufacturers, and based on insights into typical business scenarios of smart life, through smart contracts Implement smart terminal registration, scene rules, trust rules and linkage rules.

Expert judges of the competition believe that this project has practical hardware and scenarios in the field of Internet of Things, and is expected to further promote the implementation of application scenarios such as distributed AI assistants, resource sharing, life cycle management, and multi-channel payment. Truly usher in smart life.

Among the projects that won the third prize in the competition, they accurately targeted the characteristics of blockchain in terms of security and efficiency improvement, and provided practical solutions for the industries they represented. Tsinghua University The team of teachers and students found a new way to develop cross-layer full-stack blockchain security detection technology to protect other blockchain applications comprehensively, and its technical strength was highly praised by the judges.

The third prize winners were the trusted electronic certificate platform of Shenzhen E-Commerce Security Certificate Management Co., Ltd., the real estate registration platform of Wuhan Liandong Times Technology Co., Ltd., and Shandong Guanhai Data Technology Co., Ltd. The company's Rongcheng blockchain service platform,The animal husbandry blockchain traceability of Quanliantong Co., Ltd., the tourism finance alliance platform of Shenzhen Youxun Information Technology Co., Ltd., and the copyright safe deposit box of Beijing FamilyMart Technology Development Co., Ltd.

Shanghai Jiuyaojiu Information Technology Co., Ltd.’s first-responder mutual aid first aid, “Yongteng Group My Innovate”’s HaveFund, Qianhai Life Insurance Co., Ltd.’s blockchain policy management, “Huazhong Technology The university's Guanshankou Hulu Brothers' Book Campus and the Cloud Block project team's "Yun Block" account system also won the competition's Outstanding Social Value Award, Outstanding Business Design Award, Outstanding User Value Award, Outstanding Creativity Award, and Outstanding Application Integration Award respectively.

Ma Zhitao, chairman of the Golden Alliance Technical Committee, elaborated on the concept of the “public alliance chain”. He believes that the alliance chain should achieve self-sublimation and should be able to evolve into an ecosystem that provides services to the public, that is, a "public alliance chain."

Different from the public chain project’s idea of ​​“coming up with a plan first, raising funds, vigorously promoting it, raising the price, and finally investing in development”, the alliance chain project adheres to the idea of ​​“investing in development first with its own funds” , go to the production environment to verify, accumulate real customers and users, run steady trials and errors, and finally carry out promotion and publicity.” However, due to the focus on practical implementation and focusing on real applications, there is a lack of publicity, and it has no choice but to fall into a passive situation of "many people have implemented it, but few people have praised it". Golden Chain Alliance hopes that through this competition, the project team of the alliance chain will come to the stage to show their results, enhance the influence of the alliance chain, and let the public know more about the real application implementation and sustainable development of the alliance chain project.

⑵ Where can I find a more detailed explanation of blockchain applications

Blockchain applications include mathematical currency, payment and settlement, digital bills, proof of rights and interests, and bank credit reporting
Each The specific application is explained as follows:
1. Digital currency
At present, the most extensive and successful application of blockchain technology is the digital currency represented by Bitcoin. Digital currency has developed rapidly in recent years. Due to the characteristics of decentralized credit and frequent transactions, it has a high transaction value and can maintain a relatively stable price through the development of hedging financial derivatives as a quasi-super-sovereign currency. Digital currency has established digital currency transaction credit backed by sovereign currency. The greater the transaction volume and the more frequent transactions, the stronger the digital currency transaction credit foundation. Once the blockchain credit system is implemented globally, digital currency will become a gold-like global payment credit.
2. Payment and settlement
At this stage, settlement and payment of commercial trade transactions all rely on banks. This traditional method of conducting transactions through intermediaries requires the account opening bank, counterparty bank, central bank, and overseas bank. In this process, each institution has its own accounting system, needs to establish an agency relationship with each other, and needs a credit line; each transaction needs to be processed by the bank.Records, and clearing and reconciliation with counterparties, etc., resulting in slow transaction speed and high costs. Compared with the traditional payment system, blockchain payment is carried out directly by both parties to the transaction without involving intermediaries. Even if part of the network is paralyzed, it will not affect the operation of the entire system. If a universal distributed inter-bank financial transaction protocol is built based on blockchain technology to provide users with cross-border, real-time payment and clearing services in any currency, cross-border payments will become convenient and low-cost.
Take cross-border exchange as an example. If I open an account in a small bank in my country and transfer money to another small bank abroad, the transfer process under the traditional SWIFT system requires the following steps: First, I send money to the small bank to which I belong. Banks submit applications; second, small banks submit applications to large banks in the same country that have signed exchange terms; third, large banks wire transfers to overseas cooperative banks; fourth, cooperative banks remit funds to small overseas banks. Currently, the process takes anywhere from 10 minutes to two days, depending on the country. If you use blockchain-based settlement technology and place an order at a market maker while remitting RMB, a trading bank participating in the system in the world will receive the order, and the two parties will shake hands to complete the exchange. The average payment confirmation speed will be in a few seconds. Within seconds.
3. Digital bills
Digital bills are a brand-new bill presentation form developed by combining blockchain technology with bill attributes, regulations, and markets. It is completely consistent with the technical architecture of the existing electronic bill system. different. The core advantages of digital bills are mainly reflected in: First, the disintermediation of the value transfer of bills. In traditional bill transactions, bill intermediaries often use information differences to match. After point-to-point transactions are realized with the help of blockchain, bill intermediaries will lose their intermediary functions and reposition their identities. The second is to effectively prevent bill market risks. Due to the blockchain's non-tamperable timestamps and the fact that it is open to the entire network, once a transaction is made, there will be no default, thus avoiding the problems of "one vote selling more" for paper tickets and out-of-sync payment and endorsement of electronic tickets. Third, the system construction and data storage do not require a central server, eliminating the development costs of central applications and access systems, reducing the maintenance and optimization costs of the system under the traditional model, and reducing the risks caused by system centralization. The fourth is to standardize market order and reduce regulatory costs. The non-tamperable timestamp formed by the continuous connection of blockchain data greatly reduces the cost of regulatory review. The completely transparent data management system provides a trustworthy traceability path, and shared constraints can be established in the chain for regulatory rules through programming. code to achieve full coverage and hard control of regulatory policies.
4. Proof of Rights and Interests
Every node participating in the maintenance of the blockchain can obtain a complete data record. Using the characteristics of the blockchain's reliability and collective maintenance, the rights of the owners of rights and interests can be confirmed. For the need to store permanent records, blockchain is an ideal solution for scenarios such as land ownership and equity transactions. Among them, equity proof is the field that is currently the most applied. Equity owners can prove their ownership of the equity with their private keys. When the equity is transferred, it is transferred through the blockchain system.Give it to the next owner, with clear property rights and clear records. The entire process does not require the involvement of a third party.
During a keynote address at the 2015 European Financial Journalism Awards for Excellence in Trading Technology in London, Nasdaq CEO Bob Greifeld announced that the exchange intends to use blockchain technology to manage its proxy voting system. Proxy voting is an important and time-consuming operation used by a listed exchange. The application of blockchain technology can allow shareholders to vote without having to attend the company's annual meeting. People can vote using their mobile phones, and Always keep voting records. Blockchain technology is regarded as an advanced technology in the field of equity trading that can ensure transparent transactions in a shorter time.
5. Bank Credit Reference
At present, when developing commercial bank credit business, whether it is for enterprises or individuals, the most basic consideration is the financial credit of the borrower itself. Each bank uploads the repayment status of each borrower to the central bank's credit reference center. When inquiries are needed, the bank will download the reference from the central bank's credit reference center with the customer's authorization. There are problems such as incomplete information, inaccurate data, low usage efficiency, and high usage costs. In this field, the advantage of blockchain is that it relies on program algorithms to automatically record massive information and store it on every computer in the blockchain network. The information is transparent, difficult to tamper with, and has low cost of use. Each commercial bank stores and shares the customer's credit status in its own institution in an encrypted form. When applying for a loan, the customer does not have to go to the central bank to apply for a credit check, that is, decentralization. The lending institution can retrieve the corresponding information data from the blockchain. Complete all credit reporting work.
In short, blockchain has become one of the hot spots of innovation in the financial industry. However, as a new technology, blockchain also has considerable risks. The current settlement system based on blockchain technology is very sensitive to regulatory risks. If participants are worried about the uncertainty of regulatory policies, it may cause the payment system to collapse due to instability. In addition, since its operating rights are controlled by developers, the obvious technical disadvantage is that if the operator itself controls more than 51% of the computing power of the entire network, it can achieve double payment, leading to a breakdown of trust. This is also an important issue that needs to be solved during the application of blockchain technology.

⑶ In what areas can blockchain be applied?

I have seen your question. So, in what areas can blockchain be applied? The editor will answer it for you below.

Answer: Bitcoin is the first specific application of blockchain. It was proposed in a paper in 2008 by a person or group of people. Bitcoin uses the blockchain to digitally send bitcoins, as BitCoin is known, without the intervention of a third-party middleman.

But Bitcoin is not the only application of blockchain, as follows:

1. Financial field: Applying blockchain technology to the financial industry can eliminate the need for third-party intermediaries. links to achieve direct point-to-point connection, thereby greatly reducing costs while quicklyComplete transaction payment.

2. Internet of Things and logistics fields: Blockchain can also be naturally combined in the fields of Internet of Things and logistics. Through blockchain, logistics costs can be reduced, the production and delivery process of items can be traced, and the efficiency of supply chain management can be improved.

3. Public service field: Blockchain is closely related to people’s production and life in public management, energy, transportation and other fields. However, the centralized nature of these fields also brings some problems. It can be used to distinguish Blockchain to transform.

4. Digital copyright field: Through blockchain technology, works can be authenticated, prove the existence of text, video, audio and other works, and ensure the authenticity and uniqueness of ownership

< p>5. Insurance field: In terms of insurance claims, insurance institutions are responsible for fund collection, investment, and claims settlement, and often have high management and operating costs. Through the application of smart contracts, there is no need for the policy holder to apply or the insurance company to approve it. As long as the claim settlement conditions are triggered, the insurance policy can automatically settle claims.

6. Public welfare field: The data stored on the blockchain is highly reliable and cannot be tampered with, so it is naturally suitable for use in social welfare scenarios. Relevant information in the public welfare process, such as donation projects, fundraising details, fund flows, recipient feedback, etc., can be stored on the blockchain and transparently and publicly disclosed conditionally to facilitate social supervision.

The above is for your reference only, I hope you can adopt it, thank you!

⑷ What are the popular blockchain exchanges currently?

Currently popular centralized exchanges include Binance, GATE, and Huobi. GATE is more convenient for deposits and withdrawals. But decentralized trading is a trend in the future. Currently, the Loopring protocol is doing better in the field of decentralized trading in China.

⑸ Does engaging in blockchain require data analysis?

Engaging in blockchain requires data analysis. Blockchain is a distributed database technology characterized by decentralized storage and security of data. Data analysis can help blockchain extract valuable information from massive transaction data, provide users with a better trading experience, and also help regulatory agencies supervise Xiangzhu blockchain. Being engaged in the blockchain industry requires data analysis capabilities and technology.

⑹ What is blockchain and how to understand blockchain applications

Blockchain is a new application of computer technology such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithm. model. The so-called consensus mechanism is a mathematical algorithm that establishes trust and obtains rights and interests between different nodes in the blockchain system.
Blockchain is an important concept of Bitcoin. It is essentially a decentralized database and serves as the underlying technology of Bitcoin. The blockchain is a series of data blocks generated using cryptographic methods. Each data block contains information about a Bitcoin network transaction and is used to verify the validity of the information (anti-counterfeiting) and generate the next block.
Let’s talk about the social or economic significance of blockchain.Many technologies in the past were actually dedicated to "productivity", such as artificial intelligence, which is an advancement in productivity. The blockchain has greatly improved production relations and is dedicated to production relations. So why do you say that?
Because the so-called production relations are actually how business is done between people and business partners. And these things are originally in the process of people's mutual cognition, and no special procedures are used to program or quantify them.
For example, if you and I are good friends now, we can do business. If someone provokes our relationship and we are no longer good friends, we will not do business. Even if we can make money by doing business, we will not do it. , because everyone no longer has any trust in each other.
As for the blockchain, it is actually because the data has been certified by various nodes and backed up at the same time, so my data is as authentic as possible and cannot be tampered with. So in this case, you believe my data, On this basis, you can create a program, and then program the "production relations" of what kind of business contracts and business cooperation this data can be used for. In this way, everyone believes in the data and the program compiled by the algorithm. And because you believe in the data and the program, you can develop various APPs based on this program. These APPs are the relationship of production and what kind of business you are going to do. This is: Blockchain is actually a reconstruction of "production relations".

⑺ What are the core technologies of blockchain system development-blockchain transaction system development-

Blockchain technology is an emerging technology today, but it is not This is too appropriate, because this technology was born with the emergence of Bitcoin ten years ago, but it is no problem to say that it is a very hot technology now. After 10 years of continuous updates, blockchain technology has finally seen relevant applications in the past two years, and has entered the blockchain 3.0 era. In the next 3-5 years, I believe there will be more fields that require blockchain Chain system to support. Below, the editor of blockchain system development loopodo will take you to take a look at several core technologies for blockchain system development.
1. Hash algorithm
Hash algorithm is the most commonly used algorithm in the development of blockchain systems. Hash function is also called hash function or hash function. The hash function can convert data of any length into a set of fixed-length codes through the Hash algorithm. The principle is based on a cryptographic one-way hash function. This function is easy to verify, but difficult to crack. Usually, the industry uses y =h (x) to represent it. This hash function implements operations on x to calculate a hash value y.
2. Asymmetric encryption algorithm
Asymmetric encryption algorithm is a secret key method. Asymmetric encryption algorithm requires two keys: public key and private key. . maleThe public key and the private key are a pair. If the public key is used to encrypt data, it can only be decrypted with the corresponding private key. Because encryption and decryption use two different keys, this algorithm is called an asymmetric encryption algorithm
3. Consensus Mechanism
The so-called "consensus mechanism" is through the voting of special nodes. The verification and confirmation of the transaction can be completed in a very short time; for a transaction, if several nodes with unrelated interests can reach a consensus, we can think that the entire network can also reach a consensus on it.
Today’s blockchain consensus mechanisms can be divided into four major categories: Proof of Work (PoW), Proof of Stake (PoS), Delegated Proof of Shares (DPoS) and Pool verification pool.
4. Smart Contract
A smart contract is a digital, networked version of a traditional contract. They are computer programs that run on the blockchain and can execute themselves when conditions written in the source code are met. Once a smart contract is written, it can be trusted by users and the terms of the contract will not be changed. Therefore, the contract is immutable and cannot be modified by anyone.
Developers write code for smart contracts, which are used for transactions and any exchange between two or more parties. The code will contain some conditions that trigger automatic execution of the contract. Once written, the smart contract is automatically uploaded to the network. Once the data is uploaded to all devices, users can come to agreement with the results of executing the program code.
5. Distributed Storage
Distributed storage uses the disk space on each machine in the enterprise through the network, and combines these dispersed storage resources into a virtual storage device, and the data is distributed in Every corner of the enterprise. Massive data is divided according to the degree of structure, and can be roughly divided into structured data, unstructured data, and semi-structured data.
Lupuda Network Technology focuses on blockchain system development, Ethereum development, blockchain transaction system development, virtual currency platform development, currency transaction system development, and digital currency wallet system development

⑻ What blockchain apps are there

Blockchain apps include: NetEase Planet Base, Shulian App, Lianxiang Finance, Shishilin Blockchain Trading Platform, Blockchain Electronic Wallet, Ostrich Blockchain , GXS Wallet, Coin Wallet, Youling Wallet.

5. Youling Wallet

Youling App creates a personal-centered value exchange network and ecology, and creates decentralized interactive entertainment and areas for all. Blockchain new economic platform.

Youling App adopts a decentralized open model, allowing individuals (third-party developers) to develop various applications based on the Youling open platform. Each user can freely choose applications to build their own homepage, including but Not limited to: souvenirs, live broadcasts, sharing, communities, service sales, and product sales.

⑼ What is ADX Group aBey?

ADX Group aBey is generallyRefers to ABEY blockchain technology, which is currently the only technology recognized by top professional institutions in the world. Dr. Ciprian Pungila has published technical papers in mainstream professional forums and has been recognized by many top professional institutions such as Cambridge University and Oxford University.

aBey Blockchain was originally an academic research project, founded by Dr. Ciprian Pungila and Dr. Viorel Negru. It aimed to create a multi-layered architecture, programmable fast blockchain to support electronic transactions for massive transactions. Business systems.

The original intention & purpose of aBey blockchain design:

Most of the current mainstream blocks There are still many shortcomings in chain technology. From a consumption perspective, although well-known cryptocurrencies such as Bitcoin and Ethereum are called "currencies", they do not have the attribute of "consumption" due to technical hard restrictions.

Another major problem with the Bitcoin model is that the computing power required for transaction processing in this model has recently shown an exponential growth trend. Based on Bitcoin’s sustainable growth rate in 2017, Bitcoin’s energy consumption will exceed the sum of other global energy consumption by 2020.

In addition, the blockchain size in the Bitcoin database exceeded 150GB in early 2018, while the blockchain size in Ethereum was close to 400GB during the same period (today Nearly 410GB). Its efficiency in processing transactions is extremely low. The processing time of each Bitcoin transaction is an average of 2 to 3 hours.

In real life, due to hard restrictions, the initial idea of ​​Bitcoin to replace legal currency is undoubtedly a false proposition. In view of the current weaknesses of blockchain technology, two PhDs in artificial intelligence from the Department of Computer Science at the Western University of Timisoara in Romania: Ciprian Pungila & Vorel Negru designed the aBey blockchain.
