Blockchain network enterprise

2. What is blockchain? Application of blockchain technology

what is a blockchain? In essence, blockchain is a decentralized distributed ledger database, which is the underlying technology of bitcoin, and is associated with bitcoin. The blockchain itself is actually a series of data blocks generated by the use of cryptography, each of which contains the information of effective confirmation of multiple bitcoin network transactions

whenever an encrypted transaction occurs, miners with strong computing power in the network begin to use the algorithm to decrypt and verify the transaction, creating new blocks to record the latest transaction. New blocks are added to the end of the original blockchain in time order, and the account book will keep growing and extending

through the complex setting of public key and private key, the blockchain network will broadcast all the transaction books of the whole financial network in real time, distribute the transaction records to each client in real time, and ensure that everyone can only modify their own property. Of course, there are other people's transaction records in the account book. Although you can see the numerical value and the corresponding transaction address (which is basically composed of a long piece of disordered letters and numbers), you can't know the real identity of the trader without using other technical means

what is a blockchain? Since last year, the concept of blockchain has become popular, especially in some developed countries. Blockchain is also known as subversion, which is very popular all over the world. Blockchain will be the first to impact the financial instry, and then will affect a wider range of economic fields. The prediction is based on several core characteristics of blockchain: decentralization, distributed ledger, point-to-point transmission, tamper proof, etc. Because the birth of blockchain is quite magical, and its development is also concerned with the rise of bitcoin in the world, many people will confuse the relationship between blockchain and bitcoin. Some people think that blockchain is a parent-child relationship with bitcoin, while others think that blockchain was born after bitcoin. But in fact, blockchain is the underlying supporting technology of bitcoin, which can be compared with TCP / IP protocol in the Internet. From a certain point of view, bitcoin can be regarded as the first practical application of blockchain generated simultaneously with blockchain

Application of blockchain technology? Since its establishment, Bubi blockchain has been focusing on the R & D and innovation of blockchain technology and procts. It has a number of core technologies, and has made substantial innovation in many aspects, forming a number of core technological achievements, such as: mathematically proven distributed consensus technology, fast large-scale account book access technology, multi chain general ledger technology supporting business form expansion The interconnection technology between heterogeneous blockchains. On April 25, "gege integral" introced the integral system into the concept of blockchain, opened up by multiple parties, issued and exchanged integral, and promoted the circulation of integral. All cooperative institutions can jointly participate in transaction verification, account book storage and real-time settlement; The third-party payment platform of the enterprise points issuer makes the points in and out more flexible. Bubi has developed its own basic blockchain service platform, which has been applied in equity, supply chain, credit and other fields. Bubi has been committed to building an open value circulation network with the core of decentralized (polycentric) trust, so that digital assets can flow freely

what is a blockchain? Application of blockchain technology? We can use bitcoin to describe several application prospects of blockchain. Bitcoin can be said to be a decentralized currency or asset. Every bitcoin can be traced back and found by everyone at any time. This application prospect means that if the transactions between people can return to the original form of barter from the current monetary value measurement method, then the measure of value is no longer legal currency, but bitcoin or other virtual currencies or virtual assets generated by the blockchain, The benefits of the current sharing economy are just the tip of the iceberg. If this traceability, query and tamper proof feature of bitcoin is applied to credit record system, identity authentication system or property right authentication system, many things like "is this house my property?"“ Whether I am unmarried or married "will not exist at all. According to the current development trend, blockchain will not only reshape all aspects of money market, payment system, financial services and economic form, but also change every field of human life.

3.

Because the design of blockchain is a kind of protection measure, such as distributed computing system with high fault tolerance. Blockchain makes hybrid consistency possible. This makes blockchain suitable for recording events, titles, medical records and other activities that need to include data, identity management, transaction process management and provenance management. Blockchain has great potential for financial disintermediation and has great influence on guiding Global trade

extended data :

1. Blockchain is a new application mode of computer technology such as distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm, etc. The so-called consensus mechanism is a mathematical algorithm to establish trust and obtain interests between different nodes in the blockchain system

2. Blockchain is an important concept of bitcoin, which is essentially a disintermediated database and the underlying technology of bitcoin. Blockchain is a series of data blocks generated by cryptography. Each data block contains the information of a bitcoin network transaction, which is used to verify the validity of the information (anti-counterfeiting) and generate the next block

3. Blockchain - the original blockchain is a kind of decentralized database, which contains a list called blocks, with continuously growing and orderly records. Each block contains a time stamp and a link with the previous block. The block chain is designed so that the data can not be tampered with. Once recorded, the data in a block will be irreversible

4. In many cases of blockchain enterprise application, we can always see the word baas. Baas is the abbreviation of blockchain as a service, which is translated into "blockchain as a service" in Chinese. So what is blockchain as a service baas? With this question, we will follow Xiao Wang of Renren blockchain technology team to discuss it carefully
according to Xiao Wang, the concept of blockchain as a service (baas) is mainly proposed by Microsoft and IBM. To put it bluntly, it is actually a new type of cloud service, a cloud service combined with blockchain technology. For example, Microsoft's azure cloud computing platform and IBM's bluemix garage cloud platform all provide blockchain as a service baas
blockchain as a service (baas) is a space created by enterprises such as Microsoft and IBM from their own cloud service network to run a blockchain node. Compared with ordinary nodes and exchange nodes, the main purpose of baas nodes is to quickly establish the development environment they need, and provide a series of operation services based on blockchain, such as search query, transaction submission, data analysis, etc. these services can be centralized or decentralized to help developers verify their concepts and models faster. The service of baas node is reflected in: it is more instrumental and easy to create, deploy, run and monitor blockchain.

5. Heshu blockchain technology laboratory has been focusing on the R & D and innovation of blockchain technology and procts since its establishment. It has a number of core technologies and has made substantial innovation in many aspects. For example: mathematically proven distributed consensus technology, fast large-scale account book access technology, multi chain general ledger technology supporting business form expansion, interconnection technology between heterogeneous blockchains, etc. The underlying architecture of Heshu laikelib blockchain technology is committed to building an open value circulation network to make technology flow freely.

6. Tongxin Huzhu is the first project launched by Abbott financial technology, a blockchain start-up company. Founded by Yang Yong, the original founder of Dolphin Browser, Abbott aims to continuously promote the application and development of blockchain technology in China by taking network mutual assistance as the breakthrough point. As the first real blockchain landing application in China, concentric mutual aid combines open source code with practical application, and realizes the deep matching between blockchain technology and network mutual aid.

8. Due to the powerful effect of blockchain and many application fields, there are not a few enterprises carrying out the research and development of blockchain technology
according to the latest news, bat and Jingdong have announced the layout of the blockchain field, while Yingtang Zhongchuang, which uses blockchain technology for system development, has already built the blockchain platform internally, which is mainly applied to five scenarios, including finance, Internet of things public services, charity and supply chain. Alibaba's plan is to track the sales path of goods through the blockchain and establish a verification network to prevent counterfeiting. Jingdong applies blockchain to anti-counterfeiting traceability and food safety. In addition, supply chain finance is also an alternative direction.

9. At present, there are many domestic companies developing blockchain technology. For example, European crowdfunding in the water test blockchain crowdfunding project; The application of bit element in the financial trading platform system; Ant financial services, LETV finance, Wanda and Tencent are all testing blockchain related projects to varying degrees, and banking institutions also attach great importance to blockchain technology.
