What is token in blockchain
digital currency and virtual currency are actually different names. They are tokens issued based on blockchain technology. Behind them are a series of computer-generated complex codes. At present, there are thousands of digital currencies in the market. The safest and most powerful digital currency is bitcoin
digital currency is also a high-risk and high return investment proct, through appropriate investment strategies, you can get rich returns. If you have spare money, you might as well put some of it into the digital currency. There will be unexpected surprises.
Pure blockchain technology can also be applied in non-financial fields. Here are some examples of blockchain technology application:
-
cross center sharing of provident fund blacklist
ant financial blockchain and Huaxin Yong build "cloud platform of joint dishonesty punishment and deposit proof", Hainan province takes the lead in sharing the black list and deposit certificate of provident fund across centers and regions through the platform -
business service blockchain platform
the platform uses blockchain technology to open the service mode of "all-weather, zero meeting, one click" and applicants can apply for business license through the "blockchain + AI" platform, which takes only one and a half hours -
Jingdong Logistics creates a blockchain traceability platform with one click traceability of beef and mutton

there are many areas where blockchain technology can be applied, and it does not have to be related to digital currency. Cryptography focuses on blockchain information< br />
the fourth category is the asset token blockchain project. Asset token refers to linking blockchain assets to physical assets such as gold and US dollars. It is the blockchain mapping of physical assets. At present, there are no more than 10 varieties. The typical representative is usdt against US dollars, digix Dao against gold, digix. Each token represents 1 gram of Gold Certified by London Bullion Market Association
asset token has the advantages of convenient transaction and storage. First of all, asset token is more convenient for transaction. Because blockchain assets can be split, it has better liquidity. For example, at present, real estate needs to be transferred as a whole. If the real estate can be token, it can be split and purchased, which is more convenient for transaction
secondly, the token of physical assets is more concive to custody. Gold is easy to wear out and cause losses in physical transactions. However, after the token of physical assets, there is no need for physical transfer, which is more concive to the custody of physical assets.
the transaction information of bitcoin is recorded in a decentralized ledger, which is called blockchain
according to the principle of cryptography, each block is connected in chronological order to form a chain structure, so it is named blockchain.
With the rapid increase in the number of bitcoin scams, there are easy ways to check whether a cheater has been reported to have used a bitcoin address, such as in a counterfeit bitcoin gift. You can also easily report any bitcoin address associated with the fraud
check the "bitcoin abuse" database
the number of bitcoin scams has been growing rapidly. Many of them ask people to send bitcoin to the address they provide. For example, the bitcoin giveaway scam promises to double the number of bitcoins you send. Last week's major twitter hacking, for example, included many highly regarded tweets about fake bitcoin gifts
before sending bitcoin to an address, you can check whether the address is reported as fraulent. Bitcoin abuse is a popular website with a public database of bitcoin addresses used by hackers and criminals. You can look up bitcoin addresses, report fraulent addresses, and monitor addresses reported by others
if the bitcoin address you searched on the website has been reported by others, the website will display information, such as the number of times the address was reported, the date and time of the last report, the total amount of bitcoin received, and the number of transactions. There will also be a link to blockchain info for you to track transactions at that address. The site will also display all reports filed at that address

fraud alert website also provides some useful information about different types of encryption scams, such as pornography, blackmail software, Ponzi scheme, gifts, black net and theft. It provides some basic advice to prevent fraud, such as "don't trust anyone" and "verify.". The website lists the addresses of the top ten scams. According to the funds received, the most successful scams are Ponzi scheme, fake exchange and fake bitcoin gifts. YouTube also has a lot of bitcoin scams in videos and advertisements, especially fake gifts. The fraudsters claimed that celebrities such as SpaceX and Tesla CEO Elon Musk, Microsoft founder Bill Gates, Virgin Galactic chairman chamath palihapitiya and Amazon CEO Jeff Bezos were giving away bitcoin. The fake Elon Musk BTC giveaway is one of the most successful bitcoin scams, making millions of dollars
before twitter was hacked, whale alert reported on July 10 that it "can confirm that in the past four years, fraudsters have stolen only $38 million of bitcoin (excluding Ponzi scheme, which is a billion dollar instry)), of which $24 million is in the first six months of 2020."
What is blockchain? What kind of changes will it bring to the future life
blockchain is a new application mode of distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm and other computer technologies
blockchain is an important concept of bitcoin. It is essentially a decentralized database. At the same time, as the underlying technology of bitcoin, it is a series of data blocks generated by using cryptographic methods. Each data block contains the information of a batch of bitcoin network transactions, Used to verify the validity of its information (anti-counterfeiting) and generate the next block
in fact, the word blockchain does not appear in the original English version of bitcoin white paper, but the word chain of blocks. In the earliest Chinese translation of bitcoin white paper, chain of blocks was translated into blockchain. This is & lt; Blockchain & quot; This Chinese word first appeared
on January 10, 2019, the state Internet Information Office issued the regulations on the management of blockchain information services, which will come into effect on February 15, 2019
in a narrow sense, blockchain is a kind of chain data structure that combines data blocks in a sequential way according to the time sequence, and it can not be tampered with and forged by cryptography
In the end, this is undoubtedly a new life changing technology. In the future, the proction activities of the whole society will be carried out with blockchain as the underlying logic. Many things are within our reach. With the integration of artificial intelligence and big data, we can easily handle the seemingly complicated things, For example, some securities market transactions and intelligent matching of financial activitiesit's easy to understand that blockchain is the integration of people, property, man, machine, material, man, field and goods, which is packaged into a whole; A network computing center that runs on an infrastructure
