There are several common types of blockchain tokens

1.

From the current mainstream blockchain projects, blockchain projects are mainly divided into four categories: the first category: currency; The second is platform; The third category: application category; The fourth type: asset token

currencies mainly act as the "exchange media" in the field of blockchain assets, and the exchange media refer to general equivalents, such as gold and silver bills in the past< (currency exchange on trading blockchain assets)

platform projects refer to the establishment of technical platforms to meet the needs of various blockchain application development, which can rece the threshold of application development on blockchain

application projects cover a wide range of fields, including finance, social networking, games, property rights protection, etc., and are also the fastest growing fields of blockchain assets

asset token project refers to the blockchain mapping of physical assets, that is, the physical assets on the chain. At present, there are no more than 10 varieties

01 currency

the first category is currency project, which is also the earliest blockchain project. Currency projects mainly include bitcoin and lightcoin. In addition, there is another kind of asset with the characteristics of anonymity. Its main functions include protecting the privacy of both sides of payment while realizing payment. The well-known ones are dash, monero and zcash. Currency is mainly used as the "exchange medium" in the field of blockchain assets. The exchange medium is the general equivalent you use to exchange goods. For example, gold, silver and silver bills can be used as the exchange medium in the past. At present, there are more than 2100 types of digital assets in the world, and the number of currency blockchain projects has increased rapidly recently. As of June 2018, bitcoin is still the largest market value

02 platform type

the second type is platform type blockchain project. The main function of platform type blockchain project is to establish a technical platform to meet the technical requirements of various blockchain application development; In short, platform applications allow developers to directly issue digital assets and write smart contracts on the blockchain. Smart contract is a computer program running on the blockchain database, which can be automatically executed under the conditions of its source code setting

for example, you develop a smart contract based on the house rent protocol on the blockchain. When the owner receives the rent, it will trigger the automatic execution and give the security key of the apartment to the tenant

the main function of platform blockchain projects is to establish the underlying technology platform, so that developers can do application development on the underlying technology platform. A considerable number of platforms are still in the development state. As of June 2018, Ethereum has the largest market value

03 application

the third category is application blockchain projects. Application projects are blockchain projects based on blockchain development platform (such as Ethereum), which can solve many problems in various fields of the real economy

for example, augur, Golem, vechain, omisego, which provides asset exchange and transfer services. Using blockchain technology, these projects can better solve the problems of trust and cross-border circulation. At the same time, using smart contracts and tokens on the blockchain, they can better realize automatic execution and greatly improve the efficiency of social and economic activities. Application blockchain projects cover a wide range of fields, including finance, social networking, games, property rights protection and so on. It is also the field with the fastest market value increment of blockchain projects at present

04 asset token

the fourth category is the asset token blockchain project. Asset token refers to linking the blockchain assets to physical assets such as gold and US dollars, which is the blockchain mapping of physical assets. As of February 2018, there are no more than 10 varieties. The typical representatives are usdt against US dollars, digix Dao against gold, Digix each token represents 1 gram of Gold Certified by the London Bullion Market Association. Asset token has the advantages of convenient transaction and safekeeping. 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, but there is no need for physical transfer after the token of physical assets, which is more concive to the custody of physical assets

2. According to the classification of known blockchain technology applications, jinwowo group can be roughly divided into three categories:
1 - public blockchain; It means that anyone can read and send transactions for validity confirmation, and anyone can participate in the consensus process of the blockchain to jointly maintain the security, transparency and non tampering of the public blockchain data. For example,
2-community blockchain represented by bitcoin; It is also called alliance chain, which means that the nodes participating in the blockchain are selected in advance, and there are usually good network connections and other cooperative relationships between the nodes; Community blockchain is a practical application scenario of the combination of blockchain and physical goods, such as Domenech jewelry's Maobei mode
3-private blockchain: the participating nodes only have a limited range, the data access and use have strict permission management, the write permission is only in the hands of the participants, and the read permission can be opened to the outside world.

3. The first category is currency projects, which are also the earliest blockchain projects. Currency projects mainly include bitcoin and lightcoin
in addition, there is another kind of asset with the characteristics of anonymity. Its main functions include protecting the privacy of both sides of payment while realizing payment. The more famous ones are dash, monero and zcash
currency is mainly used as the "exchange medium" in the field of blockchain assets. The exchange medium is the general equivalent you use to exchange goods. For example, gold, silver and silver bills can be used as the exchange medium in the past
at present, there are more than 1000 types of digital assets in the world, and the number of currency blockchain projects is not growing fast. As of January 2018, bitcoin is still the largest market value. We are already familiar with bitcoin. In the next few episodes, we will give a detailed introction to Leyte coin, Xinjing coin, Dasch coin, Monroe coin and zcash.

4. 1. Bitcoin
it is the birthplace of blockchain technology, and the market has confidence in it. It still maintains a stable growth under the adverse situation of major policies. Once it solves the problem of capacity expansion, the price rise can be predicted
2. Ethereum
compared with bitcoin, the advantage of Ethereum is that it has no policy problems. Although the event led to its bifurcation, the establishment of enterprise version Ethereum alliance may solve this problem. Its concept and Prospect of smart contract attract many developers to follow
the essence of community operation is that the majority decides the minority when indivials support eth
3. Zec
compared with bitcoin and Ethereum, the risk of z-coin will be greater, and its value will take a longer time to reflect. But in the long run, the value of anonymity will be one of the values that human beings generally pursue
4. BTS
bitstocks are very powerful and the system is very stable. Decentralized trading, anchoring system and so on. Although the founder bm's brain damage has hurt the community, the value of bitstocks is obviously undervalued. It is a wise choice to hold bitstocks on the cheap.

5. Blockchain wallet is a tool to save the private key of blockchain digital currency. Every digital currency has a wallet. The types of blockchain wallet are as follows:
1. General wallet
can support different blockchain tokens. For example, anmao wallet supports BTC, BCH, LTC, ETH, etc, dash and erc-20 series
2. Main Chain Wallet
in order to achieve their own goals, each coin must establish its own main chain, so that it can carry out business. After the main chain goes online, it needs to use the project's own wallet. Just like the green apple wallet of GAC coin, it is a wallet dedicated to GAC trading and transaction clearing
3. Exchange wallet
there are also wallets in the exchange. If the player's currency is recharged into the exchange, the corresponding currency will enter the exchange wallet. The exchange wallet is almost the same as the ordinary wallet. You can fill in the corresponding wallet address when transferring and withdrawing cash, and the corresponding wallet address will be generated for different currencies of each exchange
4. Hardware wallet
generally speaking, the wallet is software wallet, which is a PC program or app. As the name suggests, a hardware controlled wallet can be connected to the network when it is used, and can be stored off the network at other times, so as to avoid exposing the wallet to the network space.

6. Currently known blockchain technology classification, jinwowo Group believes that it can be roughly divided into three categories:
1 - public blockchain: refers to the blockchain that anyone can read, send transactions for validity confirmation, and anyone can participate in its consensus process, so as to jointly maintain the security, transparency and tamper proof of public blockchain data
2-community blockchain: also known as alliance chain, it means that the nodes participating in the blockchain are selected in advance, and there are usually good network connections and other cooperative relationships between the nodes
3-private blockchain: the participating nodes only have a limited range, the access and use of data have strict permission management, the write permission is only in the hands of the participants, and the read permission can be opened to the outside world.

8. A new resolution initiated by representative Adam kinzinger, a Republican from Indiana, has been submitted to the US House of Representatives, calling on the government to formulate national policies on emerging technologies, including digital currency and blockchain technology
the resolution calls on the idea of bitcoin, but does not directly mention its name. Instead, it calls it "alternative illegal currency". Blockchain technology is the key point, which points out that this technology has the potential to "fundamentally change" the way trust and security are built on online transactions
but in fact, the United States has not taken action to formulate this rule. However, there is a global blockchain alliance R3 in the process of formulating the standard for the use of blockchain. Of course, blockchain is just a technology that can be used by any enterprise. In China, there is a project called decent, which is more avant-garde. It uses blockchain technology to build a decentralized content publishing platform, but it may encounter some problems in China.

9. It can be roughly divided into three categories:
1 - public blockchain: it refers to the blockchain that anyone can read and send transactions for validity confirmation, and anyone can participate in its consensus process, so as to jointly maintain the security, transparency and non tampering of public blockchain data
2-community blockchain: also known as alliance chain, it means that the nodes participating in the blockchain are selected in advance, and there are usually good network connections and other cooperative relationships between the nodes
3-private blockchain: the participating nodes only have a limited range, the access and use of data have strict permission management, the write permission is only in the hands of the participants, and the read permission can be opened to the outside world.
