Donggang real blockchain

1.

blockchain technology is a new distributed infrastructure and computing paradigm, which uses blockchain data structure to verify and store data, uses distributed node consensus algorithm to generate and update data, uses cryptography to ensure the security of data transmission and access, and uses intelligent contract composed of automated script code to program and operate data. In short, in the blockchain system, the transaction data generated by each participant will be packaged into a data block after a period of time. The data blocks are arranged in chronological order to form a chain of data blocks. Each participant has the same data chain and cannot be tampered unilaterally, Any modification of information can only be carried out with the agreement of the agreed proportion of subjects, and only new information can be added, and the old information cannot be deleted or modified, so as to realize the information sharing and consistent decision-making among multiple subjects, and ensure that the identity of each subject and the transaction information between subjects can not be tampered with, open and transparent

the technical commonness of blockchain projects: block, account, smart contract and consensus, which constitute the general model of the current blockchain system

today, I want to tell you what is a real dragon ball for blockchain application landing and enabling traditional commerce and trade

first of all, dragon ball technology will develop the electronic business platform integration asset plan, and the cable asset payment facility will serve the upcoming block chain business application landing wave. In the future, valuable assets can be applied to all aspects like WeChat payment and Alipay, which will bring convenience to people's payment and life, and at the same time, increase sales to businesses. This is the commercial value brought by Longzhu. Based on Singapore, the Longzhu foundation in Singapore will radiate the world and aspire to become the leader of new asset technology and contribute to the circulation of global commodity trade

2. Blockchain is a key project in the 13th five year plan for national informatization. It is parallel with artificial intelligence, big data, driverless and other projects. With the support of the government, blockchain technology has developed rapidly, and China's blockchain instry is expected to take the lead in the world
at present, the number of domestic blockchain related companies is increasing, among which fast online has always been in the leading position

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

5. Blockchain technology has been basically mature, and now it mainly focuses on landing applications
on the ground, there will be different solutions according to different instry needs
for example, in the financial instry, relevant financial technology companies have studied and applied it for a long time. Recently, there is a one account chain platform, which is released by Ping An's financial one account link company. It is the solution of blockchain in the financial instry. According to the introction, it has broken through the bottleneck in the implementation process.

7. In fact, in our lives, we use the money in the digital money Alipay, the money in the bank card, and the risk of choosing a good platform is not great. DCPRO is very suitable.

8. If you want to get bitcoin, now you have to spend money to buy it and invest it. Then wait for it to appreciate before you sell it to earn the difference.

9. The acceleration of simple harmonic motion is variable. Junior and senior high schools have not systematically introced how to get the solution. If we know the force at a certain moment, we can calculate the resultant force according to the second brother's law, and then calculate the acceleration at this moment. The potential energy can be obtained according to the conservation of energy and the principle of function

Smart earth NAT is decentralized, and smart earth NAT belongs to real blockchain

the smart earth is divided into three elements, namely "3I": IOT, interconnection and intellectualization, which refers to fully applying the new generation of it and Internet technology to all walks of life, and embedding and equipping sensors into hospitals, power grids, railways, bridges, tunnels, highways, construction, water supply systems, dams and oil and gas pipelines all over the world

the smart earth forms the Internet of things through the Internet; The Internet plus the Internet of things is the world's most intelligent and intelligent world. It is a shared database, and the data or information stored in it is the core feature of blockchain

extended data:

the essence of blockchain:

from the perspective of science and technology, blockchain involves many scientific and technological issues such as mathematics, cryptography, Internet and computer programming. From the perspective of application, in short, blockchain is a distributed shared ledger and database, which is decentralized, tamper proof, traceable, collective maintenance, open and transparent

these features ensure the "honesty" and "transparency" of the blockchain, and lay the foundation for creating trust in the blockchain. The rich application scenarios of blockchain are basically based on the fact that blockchain can solve the problem of information asymmetry, and realize the cooperative trust and concerted action among multiple agents

blockchain is a new application mode of distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm and other computer technologies. Blockchain is an important concept of bitcoin,

in essence, it is a decentralized database. At the same time, as the underlying technology of bitcoin, it is a series of data blocks generated by using cryptographic methods. Each data block contains a batch of information of bitcoin network transactions, Used to verify the validity of its information (anti-counterfeiting) and generate the next block
