Blockchain does not need token
Publish: 2021-05-06 11:14:14
1. blockchain is a technology to achieve decentralization, and it is an application model of a variety of Internet basic technologies. In essence, blockchain is actually an application model similar to internet protocol. The HTTP we usually log in to is an internet protocol. The Internet connects the global network through the underlying protocol, while the application protocol of blockchain is a new way to connect the network nodes distributed around the world. In the future, more and more people will understand and accept blockchain.
2. At present, there are four main types of consensus mechanisms: pow, POS, dpos, pool
1. POW workload proof, which is familiar with mining, calculates a random number that meets the rules through and or operation, that is, obtains the bookkeeping right, sends out the data that needs to be recorded in this round, and stores it together with other nodes in the whole network after verification
advantages: complete decentralization, free access of nodes
disadvantages: bitcoin has attracted most of the computing power in the world, and other blockchain applications using POW consensus mechanism are difficult to obtain the same computing power to ensure their own security; Mining causes a lot of waste of resources; The period of reaching consensus is long, which is not suitable for commercial application.
2. Proof of rights and interests of POS, a mechanism of upgrading consensus of pow; According to the token proportion and time of each node; It can rece the difficulty of mining in equal proportion, so as to speed up the speed of finding random numbers< Advantages: to a certain extent, it shortens the time to reach a consensus
disadvantages: mining is still needed, which does not solve the pain point of commercial application in essence
3. Dpos share authorization certification mechanism is similar to the voting of the board of directors, in which the coin holders cast a certain number of nodes to verify and account on their behalf
advantages: greatly rece the number of participating verification and accounting nodes, which can achieve second level consensus verification
disadvantages: the whole consensus mechanism still depends on token, and many commercial applications do not need token to exist
4. Pool verification pool, which is based on traditional distributed consistency technology and data verification mechanism; It is a consensus mechanism widely used in the instry chain at present.
advantages: it can work without token, and realizes second level consensus verification on the basis of mature distributed consistency algorithms (pasox and raft)
disadvantages: the degree of decentralization is not as good as that of bictin; The multi center business model is more suitable for multi-party participation
it has great advantages in using consensus mechanism to ensure data consistency (the consensus mechanism is first proposed by ripple, and the network transaction synchronization mechanism with data correctness priority. In the consensus network, no matter how the software code changes, if you can't reach a consensus, you can't enter the network, let alone fork)
- - - - - - - -
PS: a little black, although the consensus mechanism can absolutely ensure that there will be no hard bifurcation at any time. However, the disadvantage of this mechanism is obvious, that is, it is much longer than the current bitcoin network to reach a consensus with other nodes. In extreme cases, the consequences of disconnection in ripple consensus mechanism network are also very terrible
it is possible that one day after the power failure in your home, the whole system will no longer be able to reach a consensus with other rippled nodes (in fact, the consensus mechanism requires more than 80% of the nodes to acknowledge your data before your submission will be accepted by other nodes, otherwise it will be rejected by exclusive nodes), Even you can only empty all your 500 GB data and resynchronize to connect to other ripple nodes
so at present, the existing rippled end is not suitable for civil use (if it is commercial, the impact is relatively small. For example, RL's own rippled node is hosted in Amazon cloud data center. If it has no response for a long time, it can make high claims, and there is almost no break in that place except for large disasters). This is one of the aspects RL has always wanted to improve.

3. The development of blockchain technology is obvious to all, but there are essential differences between blockchain coin and virtual coin. It can be considered that blockchain projects developed with entity pain points have specific landing applications and entity support, and blockchain tokens issued with entity pain points still have certain value support; If there is no specific entity and application to support virtual currency, it is just air currency and has no value, then the risk is relatively large.
4. We know that the state has always advocated "no money" blockchain. That is to say, don't use the chain&# 8204;&# 8204;&# 8204; Currency, support technology development, do not support issuing currency
of course, the coin here is what we often call token, which originally means token (temporary) in computer identity authentication. With the popularity of blockchain and digital currency, people have a variety of translations for token, including token, integral, certificate, logo, indicator, etc
the understanding of token in the market can be divided into two categories
in the first category, 99% of the people think token means token, because 99.9% of the projects do the same thing. Set up a foundation, build a website, write a white paper, and then go to ICO. Because most of the projects are still in the conceptual stage, token itself has no other meaning except trading, so people call it token, which performs the function of currency to some extent
in the second category, professionals and institutions are more willing to translate token into proof of equity, or token. For example, a person's identity certificate, academic certificate, equity, bonds, points, bills, etc., are authentic and tamperable because of the proof of rights and interests. Every proof of interest becomes more secure and reliable through the protection of cryptography
therefore, blockchain is not only a technology, but also a new mode of proction and organization, even a new thinking
so, the question now is, does the blockchain project have to issue currency
answer: you may not issue currency. Not all blockchain projects need to be issued with currency, and it is not necessarily blockchain projects that issue currency
for example, the alliance chain does not need to issue coins. For example, Tencent's q-coin, in principle, is also a kind of currency, but it is not a blockchain project
therefore, the two are not related, but if they are public chains, they need to issue coins. Why
let's take bitcoin as an example. Bitcoin system as a public chain must rely on the existence of bitcoin. Public chain obtains the stability and non tamperability of its system through the nodes distributed all over the world, and these properties are the basis for the existence of public chain
imagine that if the bitcoin system is unstable or can be easily tampered with, bitcoin will be worthless. These nodes are not set up by one or several companies, otherwise they are equivalent to private chain or alliance chain. These nodes must be built dynamically by many participants. And the existence of these nodes must need some kind of incentive, otherwise why do the builders of these nodes want to participate in your system. And this kind of incentive must be integrated with the blockchain system, and it must be money
then why is it currency, not legal currency, such as RMB, as an incentive
if RMB is used as incentive, because RMB should be stored in the RMB account, and the account itself is centralized, so it's easy to be controlled. Just think about why domestic bitcoin exchanges are so afraid of the central bank, and they are afraid of being weaned. In addition, RMB can't react with smart contracts within the blockchain
the electronic currency issued by the central bank can not be used as the original currency and incentive of a blockchain system. Why
if the central bank or a rich person wants to destroy a project, they just need to take out enough e-money to do enough nodes and attack 51%. Therefore, it is impossible to use the e-money issued by the central bank as the original currency and incentive blockchain system. However, blockchain projects with independent native currency and incentives have no such worries
If a person or organization wants to get enough nodes to carry out 51% attacks, it must first get more than 50% enough coins, and the amount of coins in the market is certain, so before it gets enough coins, the soaring price will make it hard for him to bear
therefore, a public chain project must have money. A public chain project without money is like a castrated person
in addition, only through the token and reasonable stimulation of output, can the proction relationship be changed and the value of blockchain be brought into play. Therefore, the project must have token, which can promote the development of the project faster. Token solves the problem of incentive and consensus, and incentive solves the problem of autonomy. The positive autonomous economic ecosystem and the underlying technology of blockchain are a perfect combination.

5. If you want to ask what's the most popular in 2018, I believe you will say it's blockchain
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 />
1
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
2
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
< / OL >
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 />
7. The fourth type of blockchain project is asset token project. What are the characteristics of asset token project? What are the typical representatives
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.

8. The significance of bitcoin Mining: distribute the initial bitcoin
opponents of bitcoin accuse mining of wasting a lot of resources to make meaningless coin toss, while supporters take gold mining as an example. For the bitcoin system, the biggest significance of this kind of resource consumption mining is: to distribute 21 million initial bitcoins fairly, just like to consume resources to dig gold, the only way to distribute initial bitcoins fairly is to consume resources to dig bitcoins
bitcoin is a kind of digital currency based on the blockchain Technology (chainnova), and the blockchain technology is simply understood as an electronic currency account book system realized through point-to-point, which can record every transaction of bitcoin through the network, and it is decentralized, and no one can change it without authorization, Therefore, it has a very stable security for its holders
however, the fairness of all these ways of distributing initial coins is far weaker than that of burning money to obtain initial bitcoin, and fairness is the core issue of monetary system. Therefore, although bitcoin mining consumes a lot of resources, it is a reasonable economic behavior as well as consuming resources to mine.

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
{rrrrrrr}
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."
10. Blockchain "chain" everywhere? Not all fields can achieve the popularity of "blockchain"
thanks to the soaring bitcoin. Those who held bitcoin a few years ago are now laughing; People who don't have bitcoin in their hands are envious at the price of bitcoin
experts tell us that bitcoin is a virtual currency based on blockchain technology. But to ask what blockchain is, at most some people will answer: This is a kind of smart contract. And then? Little is known
but it doesn't seem to get in the way of people's attention and enthusiasm. At one time, a variety of virtual currencies and procts based on blockchain were born. People were chasing each other, and they didn't have time to know whether they were real or not. "Get on the bus first, and you won't have a chance later." this is the attitude of many people in the face of blockchain
in fact, blockchain is a decentralized distributed ledger database. Moreover, the impact of blockchain has long gone beyond the scope of virtual currency. Open a conference activity website, the number of meetings and activities about blockchain has increased significantly, "blockchain finance", "blockchain energy", "blockchain advertising"... In just a few months, blockchain seems to have reached the point of being able to cover everything
the role and value of blockchain are getting more and more recognition. However, has the blockchain really been able to exert such a great influence? Many people in the instry said that the current blockchain is still in its infancy, and many aspects need to be improved
therefore, we should be alert to following suit and hyping the concept of blockchain. In the current development stage of blockchain, not all fields can realize "blockchain". It is necessary to prevent new bottles of old wine, especially the behavior of touching the regulatory red line
before, there was a company that divided the property right of the house and put it on the blockchain platform to allow investors to trade through token. The investors bought a share of the property right. Although this business model has well applied the idea of blockchain, because token is suspected of illegal financing, which seriously disrupts the financial order and touches the red line of supervision, it has been stopped
the development of everything needs to be graal. Take big data, which became popular a few years ago, for example. Up to now, there are still some places that simply believe that the development of big data is to buy more and more servers. It can be seen that the development of big data still needs time, needless to say the newly emerging blockchain
at first glance, it is technology that brings the world to a better distance. Behind it must be people. In order to play its e role, blockchain must first have "people" to make some constructive attempts and explorations. But in terms of the current development of blockchain, we still need to do a lot of preparatory work.
