Blockchain and token

1. blockchain technology can be applied to many instries:
Art Instry
ascribe allows artists to declare ownership, issue numbered and limited edition works, and aim at any type of artwork in digital form. It even includes a trading market where artists can buy and sell through their websites without any intermediary services
legal instry
bitproof is the most advanced of many document time stamp applications emerging in recent years, which will make the traditional notarization method a thing of the past. Bitproof offers more services than versions including blocksgin and originstaemp, including one for intellectual property. Interestingly, bitproof recently cooperated with an it school in San Francisco to put their students' academic certificates on the blockchain, completely redefining how to handle and use diplomas and student certificates
development instry
colu is the first enterprise to allow other enterprises to issue digital assets. They can "token" all kinds of assets and make a profound impact on many people. Although the bitcoin wallet couperparty also allows the issuance of simple tokens and transactions among other wallet holders, the tokens of colu can be set with various states and types, and can be detached from or returned to the system. When the data stored on the blockchain is too large, the data can be stored on the BitTorrent network
network mutual aid instry

concentric mutual aid is the first blockchain network mutual aid platform to be implemented and applied. Technically, through blockchain and big data technology, the defects of traditional network mutual aid mode can be eliminated, and a new open and transparent network mutual aid platform can be established.

2. 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.

4. 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.

5. Ethereum is a low-level system that can realize intelligent contract and open source on the blockchain. At present, the biggest development problem of Ethereum is that all applications use the main chain, which leads to the main chain not being separated and blocking seriously. The mission of aelf (ELF) is to solve it,? LF emphasizes the pure decentralized network, the side chain and the main chain can flow, and the asset side chain is connected to the main chain. It focuses on the "n-side", because it turns the planar blockchain structure into a three-dimensional multi-dimensional structure. It can divert the block trading volume to the greatest extent. Therefore, problems like "blocking" or even "paralyzing" existing in Ethereum will not appear on aelf. This is also the reason why elf token will double in two weeks, indicating the development direction of the next regional chain technology.

6. Blockchain technology is the underlying technology of bitcoin, and bitcoin is the first application of blockchain
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.

7. The distributed bookkeeping mode of accompanying logistics + blockchain can make the business data and financial data of each enterprise recorded on the blockchain, so that the regulatory authorities can monitor them in real time and can not tamper with them. This solves the practical problems in traditional logistics, such as the difficulty of tracking documents, the difficulty of recovering the right of accounts receivable, and provides energy for enterprises.

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."

9. It's illegal to look at things from the perspective of lawyers, so don't look at everything from the perspective of lawyers, otherwise you can't do anything!
