Does blockchain technology necessarily produce token
at the same time, it can provide mutual trust for transactions by using trusted self-executive code, so as to rece uncertainty and promote digital transfer and asset transactions
bitcoin is the most well-known blockchain as an encryption currency that uses blockchain technology to realize alternative payment. Bitcoin is a kind of unlicensed blockchain, also known as public blockchain, which does not restrict the identity of users who consume bitcoin or participate in verifying the authenticity of transfer blocks in the blockchain (an energy intensive process, also known as "mining"). These miners get token, or bitcoin, in return, and given that everyone can view the block (though anonymously), the blockchain itself is somewhat transparent
bitcoin is controversial and banned by many countries e to user anonymity to a large extent. However, it is worth noting that the anonymity and energy use of bitcoin are its own characteristics, not the characteristics of the whole blockchain technology.
since last year, a variety of digital currencies have emerged in an endless stream, and blockchain has also been on fire
many people are connected with blockchain as soon as they mention currency speculation; As soon as you hear that an enterprise is doing a blockchain, you will immediately ask if you want to issue money
it seems that blockchain is equivalent to digital currency, and the purpose of studying blockchain is to speculate in currency< br />

when you are new to blockchain or digital currency, it is reasonable to equate blockchain with currency speculation
after all, if it wasn't for the growing popularity of bitcoin, no one might have paid attention to blockchain technology so far. If it wasn't for more and more people investing in bitcoin, no institution would have issued a variety of other digital currencies
however, after in-depth understanding of blockchain and digital currency, we still think that blockchain is money speculation, so our understanding is really a bit biased
blockchain is the underlying technology of bitcoin. No matter bitcoin, Ethereum, lightcoin or other various tokens, they are all applications based on blockchain technology
but this does not mean that the blockchain can only be used to issue money, just like fish is raised in the water, but it can not be said that fish is water, and hairy crabs and crayfish can grow in the water
in addition to the various tokens we see at present, blockchain has a very broad application prospect

so what is a blockchain
to put it clearly, blockchain is: "blockchain is a kind of technical mole or encryption algorithm that is both basic application and top-level design. It breaks the barrier that an information is only saved by one central server or multiple services in the past, and copies the same information to more places at the same time, such as 1 million servers. Only when more than half of the stored information has been tampered with can chaos be caused. "
in a word, understand the relationship between bitcoin and blockchain:
blockchain is a technical concept born from bitcoin encryption technology
bitcoin is a kind of digital virtual currency, followed by the payment currency as a contribution to storage computing power
if you want to store the same information in countless servers, who will store it for free? There has to be a reward. Bitcoin is a reward for accepting free storage. This reward is a virtual thing called bitcoin.
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 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.
First, what is blockchain
blockchain is a technology system which is jointly maintained by multiple parties, uses cryptography to ensure the security of transmission and access, and can achieve consistent data storage, tamper proof and non repudiation
before trustcoin, bitcoin was the first successful application of blockchain technology
the essence of honest currency is a multi person bookkeeping account book, which belongs to a kind of digital asset and a kind of virtual currency like special currency
for example, if a has five integrity coins and transfers them to B, you only need to record the transaction in the account book and the transfer is successful. As like as two peas, the distributed accounting system is implemented in block chain technology. With such a powerful account book, we do not need WeChat, do not need Alipay, do not need the bank and other three party agencies to help us to keep accounts, and we can all participate in the bookkeeping work. p>
cryptography ensures that as long as we do not lose our own key, others will not be able to forge our transactions and then transfer our digital assets
Second, what is the role of blockchainbitcoin is the first blockchain application that has been proved successful. It teaches the world how to transfer value without trusting a third party. Blockchain technology can effectively remove the trust problem of information asymmetry
How doesblockchain technology work
We know that there is no trust between people. In the transaction, it often needs a third party agency as an intermediary guarantee. The reason why blockchain can reconstruct the previous trust between people essentially depends on the way that every transaction is recorded by everyone, which is transparent and verifiable, difficult to tamper with, and even more undeniableno longer needs centralization of the administrator, do not need banks, Alipay, WeChat as an intermediary, efficient transfer of value. p> Thirdly, what is integrity currency
integrity coin is a digital asset based on blockchain technology, just like a game; The game is very special. Under the rule of district centralization, there is no leader, no one has the final say, no judge. So everyone is the referee, the weight is the same, so we can realize the supervision of information and ensure the transparency of information
in the process of continuous trading, the reward mechanism is integrity coin, which is based on the distributed ledger jointly maintained by a community. Everyone in the community should be informed whether there is any change in the account book
and the process of obtaining integrity money through continuous exchanges is called mining
< H2 > Fourth, the relationship between virtual currency and blockchainin essence, digital currencies such as bitcoin, integrity coin and Leyte coin are virtual tokens generated under blockchain technology. Without blockchain technology, there would be no such digital assets
