On the ownership management system of blockchain

1. In the blockchain equity management chain system developed by Yingtang Zhongchuang, this system can realize the registration, transfer and OTC trading of equity on the blockchain. Based on the application scenario of VC, the blockchain equity management chain selects and matches the blockchain consensus algorithm and system security level. It has high flexibility and scalability, and can be used in other equity management or similar functions in the future

What is blockchain finance

blockchain finance is actually the application of blockchain technology in the financial field. Blockchain is a kind of underlying technology based on bitcoin, and its essence is actually a decentralized trust mechanism. By sharing in distributed nodes, we can collectively maintain a sustainable growing database and achieve the security and accuracy of information. It is also a new technology system formed by integrating the existing technologies such as distributed storage, asymmetric encryption algorithm and timestamp, and introcing the consensus mechanism of algorithmic game theory

there are still many problems to be solved in order to achieve the goal of decentralization of blockchain. The traditional supply chain finance is a centralized mode. Basically, financial institutions and factoring companies rely on a core enterprise to provide services for about 80% of the SMEs in the supply chain. However, in the process of supply chain operation, logistics information, transaction information, capital information and information flow information are scattered within their own enterprises, and the information is not transparent, so financial institutions can not fully understand the enterprise credit, so it is difficult to avoid the phenomenon of reluctant to lend

first of all, relying on technology to greatly decentralize will proce new problems, and technical decentralization is not equal to market management decentralization. Whether the application of blockchain in the financial field can fully respect and protect the rights and interests of consumers still needs to be guaranteed by the regulatory authorities

financial enterprises have begun to use blockchain technology for self strengthening. For example, commercial banks can use blockchain technology to better manage points and collateral, better solve the problems of identity authentication and anti money laundering in the development of Internet finance, and promote the upgrading of Internet finance

in addition, by using blockchain and supporting technologies, commercial banks can better provide intelligent investment advisory and cash management services, and move towards the direction of transaction banks. In the future, Huixin cloud software collaborative service platform, the proct managers of the platform with the spirit of research, will conct in-depth research on the application scenarios of the blockchain. The scenarios will become increasingly rich, and the pace of technological innovation and mode innovation will be accelerated. With the application scope accelerating from financial to non-financial fields, the blockchain will graally become an important part of the future Internet, To lay an important foundation for building a value network

the above content comes from the interception part of the network library: blockchain financial system solution

hope to adopt, and you can refer to the network library: blockchain financial system solution if you don't understand

3. Generally speaking, blockchain system consists of data layer, network layer, consensus layer, incentive layer, contract layer and application layer
among them, the data layer encapsulates the underlying data block and related data encryption and timestamp technologies; The network layer includes distributed networking mechanism, data transmission mechanism and data verification mechanism; The consensus layer mainly encapsulates all kinds of consensus algorithms of network nodes; The incentive layer integrates economic factors into the blockchain technology system, mainly including the issuance mechanism and distribution mechanism of economic incentives; The contract layer mainly encapsulates all kinds of scripts, algorithms and smart contracts, which is the basis of the programmable characteristics of blockchain; The application layer encapsulates various application scenarios and cases of blockchain. In this model, chain block structure based on timestamp, consensus mechanism of distributed nodes, economic incentive based on consensus computing power and flexible and programmable smart contract are the most representative innovations of blockchain technology.

4. In the blockchain system, it is necessary to describe the ownership, protect the ownership, store the transaction data, distribute the ledger to an untrusted environment, add transaction records to the ledger, and decide which ledger determines the truth
bitcoin is a typical blockchain system, which can be studied carefully

Innovation is the driving force of development, and the protection of intellectual property rights is to protect and encourage innovation, so as to promote the progress and development of economy and society

take the example of micro right, a blockchain intellectual property protection platform of e-baoquan, which combines intellectual property protection with digital technology, and uses the characteristics of stable and tamper resistant blockchain storage to store work data on the blockchain in the form of hash encryption for blockchain confirmation, so as to help users register relevant information of works in the blockchain

The hottest things this year are "bitcoin", "Ethereum" and all kinds of cryptocurrencies, so hot that even aunts and uncles are about to start talking about them. It is no exaggeration to say that 2017 is the first year of the development of cryptocurrency and blockchain technology

as the underlying technology behind bitcoin, the concept of blockchain has only been mentioned in the past two or three years, although as early as 2009, "Nakamoto Tsung" released bitcoin. After this wave of digital currency boom, the concept of blockchain technology has really entered the eyes of all walks of life. I'm afraid it's too early to mention the wide application of blockchain technology, which is still in a very early stage of development. However, e to the arrival of the boom, many technicians and teams have contributed their efforts to build some blockchain concept projects“ Needless to say, as the first application of blockchain technology, bitcoin of "Zhongben cong" has realized the function of distributed ledger, which can realize the first decentralized value transmission of human beings. It can be said that it is "blockchain 1.0". Then Ethereum invented the smart contract, which extended the function of blockchain technology to build applications. It is well deserved to be defined as "blockchain 2.0". However, the blockchain concept projects that came out later did not realize this leap forward role, but only improved to a certain extent at the application level, so they can not be called "blockchain 3.0"

so what is "blockchain 3.0"? Maybe bitcoin OS is the answer: an operation system that is completely based on blockchain technology and follows the concept of blockchain technology. In the 1980s, before Microsoft released the windows operating system, personal computers and Internet technology were still in a non systematic state and could not be popularized. After the release, personal computers were allowed to enter ordinary people's homes, making PC and Internet universal application procts. Recently, bitcoin OS team announced the implementation of the bifurcations of bitcoin and Ethereum on Christmas day, so as to officially publish the plan of developing blockchain OS

anyone who knows a little bit about blockchain technology knows that bitcoin solves the problem of account book, while Ethereum is a smart contract to realize application expansion. Later, a team will launch a distributed storage project. But these systems with only a single functional mole are not "operating systems". The traditional definition of operating system is a huge management and control program, which includes five management functions: process and processor management, job management, storage management, device management and file management. In fact, the OS based on blockchain does not need to change all the five functional blocks into distributed ones, as long as the parts related to the external transmission of value and information can be decentralized and distributed. Therefore, the blockchain operating system should have at least three functions of "account system management, computing resource management and storage resource management", which can realize distributed ledger, edge computing and edge storage. Although it is still too early to define the instry standard in this way, bitcoin OS team is committed to realizing the blockchain OS possessed by these three functional blocks first, and then improving it through iteration

according to the bitcoin OS team, the name "bitcoin OS" is actually "blockchain OS", which is named after "bitcoin", which is also a tribute to the inventor "Satoshi Nakamoto". At present, from the technical details given by the bitcoin OS team, we may be able to see some aspects of this "blockchain 3.0" project

firstly, the management function of the account book system supports locating the ownership of resources according to the account ID, such as the private key; Computing resource management can obtain corresponding computing resources according to the demand, support edge computing, and share distributed computing power. In addition, storage resource management can use storage resources according to the demand, and support edge storage. Compared with bitcoin OS, Ethereum only supports account system and smart contract, which can not meet the distribution of distributed computing tasks. Ethereum only supports the fair execution of contract code, let alone the management of storage resources. So Ethereum is only a custom calculator

in addition, it is worth mentioning that bitcoin OS self customized enhanced smart contract. It supports two modes, which are more flexible and efficient

1. Central computing mode: the outgoing node is responsible for executing the smart contract, and both the incoming parameters and the output results support sipfs to be stored in the storage node

Distributed computing mode: ordinary nodes can claim computing tasks, input parameters and output results support sipfs storage to storage nodes

finally, we also need to mention the built-in sipfs super interstellar file system of bitcoin OS. Sipfs can realize the decentralized storage of technical input parameters and output parameters. At the same time, the file has a life cycle, and the DNA description of the file descriptor is recorded on the blockchain. The file descriptor of sipfs does not exist on the blockchain, but it will be stored in a separate file descriptor data file. After the end of the file life cycle, the blockchain will automatically delete the file descriptor, Realize the intelligent slimming of blockchain

"blockchain 3.0" is worth looking forward to, and bitcoin OS team, as the vanguard, is worth paying attention to and encouraging. We are looking forward to the real blockchain operating system

7. 1. Blockchain is a distributed database (system) in a non secure environment
2. The blockchain uses cryptography to ensure that the existing data cannot be tampered with
3, the blockchain uses consensus algorithm to reach consensus on new data. The system with the above three properties is blockchain. Shengshi Huacai did a good job in this blockchain

8. There are many practical applications of blockchain. The domestic land management right transfer market is mainly local, and there is a large information asymmetry, which brings inconvenience to both sides of investment and financing. In the development scheme of Yingtang Zhongchuang's blockchain land management right asset management system, the system can provide information trust foundation based on blockchain for cross regional land circulation, and define multiple roles in the circulation process, providing functions such as land data verification, information storage, electronic voucher for transaction settlement, etc, To help land management rights transfer more safely and conveniently.

9. Yes, led by the people's Bank of China and developed by Jiangsu Rongze Information Technology Co., Ltd., the crown number circulation platform based on blockchain technology can manage the crown number generated by the inter-bank payment business of various financial institutions, and realize the synchronous circulation of number information and things. That is to say, with this management system, where does the RMB circulate, Whether there is the risk of money laundering, cracking down on illegal activities of RMB, and the risk of counterfeit currency have been well prevented. Everything is under the information record of the blockchain system, and it can not be tampered with. It is practical and convenient, recing 70% of the repeated sorting of cash objects.

10. It can save labor cost and realize the traceability of every RMB in the whole process of circulation in financial institutions. It is of positive significance for RMB circulation management, preventing the risk of counterfeit currency, preventing the risk of money laundering, and cracking down on illegal and criminal activities related to RMB transactions. At present, only Rongze is doing this in the pilot, and if the effect is OK, it will be spread out more.
