One for blockchain domain name

1. 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.

2. "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.

3. Now there are many frauds in the digital currency trading platform. For the sake of safety, you'd better ask professionals, because you can't verify the authenticity of what others recommend, so as not to be cheated.

4. 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.

5. [verify signature]
jump out of the verification interface, click the return button in the upper left corner, and then upgrade to the latest version to refresh the node. Or uninstall again and restore the account with mnemonics Refresh node] in free communication, the + sign in the upper right corner, "node detection & quot;

6. 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

7. Vone platform is one of the three platforms of Shanghai wanglian technology, which has the characteristics of distribution and decentralization. There is no central node and hierarchical management structure in vone. It achieves organizational goals through the interaction, competition and cooperation between the bottom-up network nodes.

8. I didn't say it's the most suitable, because it's all the same, but many projects used. IO at the beginning, so the following project imitation leads to many blockchain projects using IO
