What is a blockchain company
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.
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.
belongs to the information instry, blockchain is a distributed digital ledger, which records all the transactions that have occurred and have been unanimously recognized by the system. Each block is like a hard disk, which saves all the above information, and then encrypts it through cryptography technology. The stored information cannot be tampered with
can be applied in different fields, as follows:
1. In the financial field
blockchain has great potential value in international exchange, letter of credit, equity registration, stock exchange and other financial fields. The application of blockchain technology in the financial instry can save the third-party intermediary link and realize the point-to-point direct docking, so as to greatly rece the cost and quickly complete the transaction payment
2. The Internet of things and logistics
blockchain can also be naturally combined in the field of Internet of things and logistics. Through blockchain, we can rece logistics costs, trace the proction and delivery process of goods, and improve the efficiency of supply chain management. This field is considered as a promising application direction of blockchain

extended data
characteristics and development planning of blockchain
I. characteristics
1. The biggest feature of blockchain technology is to create an integrity system of digital society. In this system, not only data transmission is convenient, but also counterfeiting is difficult
2. Another feature of blockchain technology is that it can realize the timely sharing of data and can not be tampered with. In the field of government services, the use of blockchain data sharing mode can realize the joint maintenance and utilization of government data across departments and regions, promote business collaboration, and facilitate the masses to handle affairs
2. Development planning
major countries in the world are speeding up the development of blockchain technology, and China has a good foundation in the field of blockchain
the 13th five year National Informatization Plan issued by the State Council, the 13th five year development plan for information technology of China's financial instry issued by the people's Bank of China and the white paper on China's blockchain technology and application development led by the Ministry of instry and information technology all clearly put forward the need to strengthen the basic R & D and frontier layout of blockchain technology, The standardization roadmap of blockchain technology development in China is proposed
