Blockchain digital currency Hans

1. Thank you
thank you
to know the difference between them, we need to know the definition of them first
digital currency: short for digiccy, which is the abbreviation of "digital
currency", is an alternative currency in the form of electronic currency. Both digital gold coin and cryptocurrency belong to digiccy
blockchain: blockchain is a new application mode of distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm and other computer technologies. Blockchain is essentially a decentralized database, also known as the trust machine
from the above definition, we can know that blockchain is a technology, and digital currency is a kind of virtual currency
digital currency is not equal to blockchain
many people will understand blockchain as blockchain. Here I want to correct that digital currency is not equal to blockchain. Digital currency is only an application of blockchain, and some digital currencies may not be applied to blockchain technology.

2. In a narrow sense, blockchain is a kind of chained data structure that combines data blocks in chronological order in a way of sequential connection, and it is a distributed account book that can not be tampered with and forged by cryptography. In a broad sense, 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
nowadays, the mainstream digital currencies are basically developed based on blockchain technology. Blockchain is the underlying technology of digital currency. The domestic tea based digital currency Puyin is developed based on blockchain technology.

3. Blockchain is characterized by decentralization, trust, collective maintenance and reliable database

for example, Sunzi asked Li Zi to borrow 100 yuan, but Li Zi was afraid that he would default, so he asked the village head to do notarization and add the account. This is called centralization. But if you don't ask the head of the village, you can shout "I'll lend my grandson 100 yuan! Please put it in the account book. "This is called decentralization. In the past, the village head was highly respected and had a good command of the accounts of the whole village. Everyone kept their money with him. This was the past trust in centralization. Now, everyone is worried that the village head will secretly misappropriate everyone's money. What should we do? So everyone sent an account book to everyone. Anyone who transfers money between them releases information through the loudspeaker. After receiving the information, everyone records the transaction in their own account book. This is called decentralization. With distributed ledgers, it doesn't matter if Lao Zhang or Lao Li's ledgers are lost, because Lao Zhao, Lao Ma and other families have ledgers

digital currency is abbreviation of digital currency. It is an alternative currency in the form of electronic currency. Both digital gold coin and cryptocurrency belong to digiccy. Blockchain technology service upgrade technology

4. Digital currency is an application of blockchain
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
taking the tourism instry as an example, blockchain applications mainly focus on tourism travel, tourism community reviews, digital identity management, credit consumption management, tracking pilot's professional certificate and qualification, loyalty plan of hotels and airlines, reservation management and consumption points management. In addition, blockchain also has applications in finance, games, entertainment and other fields.

5. There are many of the best blockchain digital currency trading platforms in China. Please pay attention to the distinction. Foreign ones can also be used.

6. Blockchain digital currency refers to cryptocurrency. The underlying technology is blockchain. There are many cryptocurrencies. Bitcoin is more famous. Detailed digital currency can be found in cryptofinance mimacaijing.

7. DAPP application is useful. Currency is fake. It's just an application.

8. Blockchain and distributed ledger technology make the development of digital currency more reliable. However, the current price of digital currency development is high. Many platform operators are not willing to be real digital currency, so they will choose templates and the like. The platform is unstable and unsafe

specific development enterprises, such as Hujin factory, use encryption technology to ensure that any new information in the account book can not be tampered with, and this kind of account book has stronger defense against external attacks.
