Domain names related to blockchain

3.

A: the main application fields of blockchain technology are finance, Internet of things and logistics, public service, digital right, insurance and public welfare

First, in the field of finance,

blockchain has great potential application value in international exchange, letter of credit, equity registration, stock exchange and other financial fields

Second, 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

Third, in the field of public service, blockchain is closely related to people's proction and life in the fields of public management, energy and transportation. However, the centralization of these fields also brings some problems, which can be transformed by blockchain

Fourthly, in the field of digital right, through blockchain technology, works can be authenticated to prove the existence of text, video, audio and other works and ensure the authenticity and uniqueness of ownership

In the field of insurance, insurance institutions are responsible for fund collection, investment and claim settlement, and often have higher management and operation costs

Sixth, the data stored on the public welfare field

blockchain is highly reliable and tamperable, which is naturally suitable for social public welfare scenarios. The relevant information in the public welfare process, such as donation project, collection details, fund flow, recipient feedback, etc., can be stored on the blockchain, and can be made transparent and public, which is convenient for social supervision

4. There are still many blockchain trading platforms, such as coin an, fire coin, OK and so on, which are relatively large platforms
blockchain is the core supporting technology of digital cryptocurrency system represented by bitcoin. The core advantage of blockchain technology is decentralization. It 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 common high cost, low 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.

5. "Blockchain is a new application mode of distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm and other computer technologies. The so-called consensus mechanism is a mathematical algorithm to establish trust and obtain rights and interests between different nodes in the blockchain system. "
I. the meaning of blockchain
in a narrow sense, blockchain is a kind of chained data structure composed of data blocks connected in sequence according to the time sequence, and it is a distributed account book that can not be tampered with and forged by means of cryptography
broadly speaking, 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
ENS is Ethereum domain name service, a distributed, open and extensible domain name system based on Ethereum. Some hash addresses used in Ethereum ecosystem are usually very long, such as Ethereum wallet address and swarm file hash address, while ENS domain name system is designed to provide users with short and easy to read domain names. Ens does not grant any trademark or declare any ownership. The domain name application of ENS is a completely decentralized process. The domain name is not obtained through purchase. You need to deposit a certain amount of ether coin in the corresponding registration contract as a deposit for at least one year. In order to avoid garbage and meaningless operation, the process of auctioning domain names includes locking deposit and destroying penalty, trying to ensure that the domain name will be registered by the actual user. The ether money spent in the process will eventually be returned to the successful bidder and destroyed in breach of contract. It will not generate income and is completely non-profit.

6. Blockchain application fields:
1. Financial field. Blockchain has great potential application 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. 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

3. Public service. Blockchain is closely related to people's proction and life in public management, energy, transportation and other fields, but the centralization of these fields also brings some problems, which can be transformed by blockchain. The decentralized and fully distributed DNS service provided by the blockchain can realize domain name query and resolution through the point-to-point data transmission service between nodes in the network. It can be used to ensure that the operating system and firmware of an important infrastructure have not been tampered with. It can monitor the status and integrity of the software and detect bad tampering, And ensure that the data transmitted by the system using the Internet of things technology has not been tampered with< 4. Digital rights. Through blockchain technology, works can be authenticated to prove the existence of text, video, audio and other works, and ensure the authenticity and uniqueness of ownership. After the works are confirmed on the blockchain, the subsequent transactions will be recorded in real time to realize the full life cycle management of digital rights, and can also be used as a technical guarantee in judicial evidence collection. For example, mine labs, a start-up company in New York, developed a metadata protocol based on blockchain. This system called mediachain uses IPFs file system to realize right protection of digital works, mainly for right protection applications of digital pictures

5. Insurance. In terms of insurance claims, insurance institutions are responsible for fund collection, investment and claims settlement, and often have higher management and operation costs. Through the application of smart contract, there is no need for the applicant to apply or the insurance company to approve. As long as the claim conditions are triggered, the automatic claim settlement of the policy can be realized. A typical application case is lenderbot, which was launched by the blockchain enterprise stratumdeloitte and payment service provider lemonway in 2016. It allows people to register customized micro insurance procts through the chat function of Facebook messenger to insure the high value items exchanged between indivials, and the blockchain replaces the third party role in the loan contract< 6. Public welfare. The data stored on the blockchain is highly reliable and tamperable, which is naturally suitable for social public welfare scenarios. The relevant information in the public welfare process, such as donation project, collection details, fund flow, recipient feedback, etc., can be stored on the blockchain, and can be made transparent and public, which is convenient for social supervision.

7. Coin security is the No.1 exchange in cryptocurrency, which means that coin security has a more complete ecology than Ethereum. In the future, the public chain can feed back the business of coin security master station, so from the perspective of ecology, coin security has a larger pattern.

8. Many new instries use IO, artificial intelligence and so on
com is almost registered, and start-ups have no money to apply for com, so they use IO, a domain name with IT instry characteristics

9. Is your company: Beijing Block Technology Co., Ltd?
