What country is blockchain
Blockchain is an important concept of bitcoin. In essence, it is a decentralized database, as well as the underlying technology of bitcoin< br />
the core advantage of blockchain technology is decentralization, which can realize point-to-point transaction, coordination and cooperation based on decentralized credit in a distributed system without mutual trust by means of data encryption, time stamp, distributed consensus and economic incentive, so as to solve the high cost and low cost of centralized institutions Low efficiency and data storage insecurity provide solutions
the application fields of blockchain include digital currency, token, finance, anti-counterfeiting traceability, privacy protection, supply chain, entertainment, etc. with the popularity of blockchain and bitcoin, many related top domain names have been registered, which has a great impact on the domain name instry.
Blockchain is a special network account book. The core of blockchain technology is digital encryption. As early as 1991, a group of young people invented a new set of mutual authentication encryption technology in order not to tamper with the date of electronic documents. By means of cryptography, they concatenated and protected the concatenated text records (also known as blocks)
blockchain stores data in blocks, and each block is queued in strict order to form a "chain". If someone wants to change the content of a block, the unique characteristics of the block will also change, and the following blocks will not recognize it immediately, and the "fake" block will have to break away from the chain
extended data
users all over the world can connect their servers to the blockchain network and become an independent node in the distributed database storage system. Once joined, the node will enjoy the same rights and obligations as all other nodes
therefore, people who carry out services on the blockchain can read and write to any node in the system. All nodes in the world will synchronize again and again according to some mechanism, so that the data of all nodes in the blockchain network is completely consistent
because of the two characteristics of immutability and decentralization. Blockchain is a good solution to the problem of trust in modern commercial society. It has emerged in financial services, Internet of things, public services, social welfare and supply chain management
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

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
