『一』Classification of digital currencies

Digital currencies can be roughly divided into three types, namely legal digital currencies, virtual currencies and digital currencies of trusted institutions.

The digital currency of a trusted institution means the digital currency issued by the enterprise as an endorsement. In traditional finance, larger companies such as Alipay and WeChat are represented by platform coins issued by exchanges in digital finance. In digital currencies, the only projects that are easiest to attract money are exchanges. As digital currencies It exists at the top of the monetary food chain. Virtual currencies can be divided into altcoins and value coins, such as value coins such as Bitcoin. As the first blockchain application, Bitcoin is the undisputed leader of encrypted digital currencies. Legal digital currency is a digital currency issued by the state as an endorsement. This type of digital currency has the same issuance efficiency as the banknotes issued by the state itself.

Digital currency is an alternative currency in the form of electronic currency. Cryptocurrency and digital gold coins are both digital currencies. The currency is a digital and unregulated currency, generally issued and managed by developers, and accepted and used by members of specific virtual communities.

『二』Who knows how many types of digital currencies there are?

At present, I believe everyone knows about the mainstream digital currencies, such as Bitcoin, Ethereum, etc., these are all It is a relatively mainstream currency. There are still many altcoins on the market. These currencies themselves have no value, but after some marketing and promotion, their value has increased significantly. A large number of altcoins are under the guise of blockchain. Money-scamming project.
Ecological
Bitcoin, as the first blockchain application, was created by Satoshi Nakamoto in 2009 and is the undisputed leader of encrypted digital currencies. The total amount is 21 million, the maximum block size is 1M, and the block generation time is about 10 minutes. It adopts POW mining method and has the characteristics of decentralization, global circulation, security and concealment. Since Bitcoin is the first blockchain project, although applications cannot be built on it due to design considerations, many other digital currencies have more or less learned from Bitcoin's design model, so Bitcoin has certain advantages in the blockchain field. Of great and extraordinary significance!
Platform type
Ethereum Classic, Ethereum Classic is actually the earliest Ethereum currency. Since 2016, TheDAO was hacked by hackers who exploited smart contract vulnerabilities and transferred 50 million in market value. USD Ethereum. In order to recover investor assets, the Ethereum community finally voted, and most participants agreed to change the Ethereum code to recover losses. In the end, the actual hard forks were named ETC and ETH respectively. ETC can be considered an old chain, but there are still A considerable number of community supporters are unwilling to give up ETC and insist on it. ETC still insists on being decentralized, irreversible, and uninterrupted by third-party review. The total amount of Ethereum Classic is fixed at about 210 million-230 million, and decreases every 5 million blocks.20% faster.
Application type
Bitcoin Cash, Bitcoin Cash is the currency that was hard forked by Bitcoin on August 1, 2017. The total amount is 21 million, and the block size supports up to 8M, excluding The SegWit code has basically the same characteristics as Bitcoin, but as a representative of large blocks, each block can accommodate more transactions, which reduces transaction congestion on BTC to a certain extent.
The above is the relevant information about the types of digital currencies. Although there are many types of digital currencies, they generally belong to the above three types. If you want to distinguish the types of digital currencies, you can compare them with each type of currency. .

『三』 What are the currency projects in blockchain projects?

The first category is currency projects, which are also the earliest blockchain projects. Currency projects mainly include projects such as Bitcoin and Litecoin. In addition, there is another type of asset that has the characteristics of anonymity. Its main functions include realizing payment while protecting the privacy of both parties. The well-known ones include Dash, Monero and Big Zero that use zero-knowledge proof. Coin (Zcash), etc. Currency mainly serves as the "medium of exchange" in the blockchain asset field. The medium of exchange is the general equivalent that you use to exchange for goods. For example, in the past, gold, silver, and banknotes could be used as media of exchange. Currently, there are more than 1,000 types of digital assets in the world, and the number of currency blockchain projects is not growing rapidly. As of January 2018, Bitcoin still has the largest market value. Everyone is already familiar with Bitcoin. In the next few episodes of Huo Xiaobi, we will introduce Litecoin, NEM, Dash, Monero, and Zcash in detail.

『四』 What are the classifications of blockchain and what is the structure of blockchain

The concept of blockchain has been quite popular recently, and it comes from Bit The implementation of cryptocurrencies such as coins, but this technology has been gradually used in various fields. So do you know what the classifications of blockchain are? What is the structure of blockchain? Let’s follow us to find out more.
What are the classifications of blockchain?
1. Public Blockchains (PublicBlockChains)
Public Blockchain means: any individual or group in the world can send transactions, and the transactions can be effectively confirmed by the blockchain, and anyone can participate its consensus process. The public blockchain is the earliest blockchain, and it is also the most widely used blockchain at present. The virtual digital currencies of all major bitcoins series are based on the public blockchain. There is one and only one corresponding to this currency in the world. Blockchain.
2. Consortium (Industry) Blockchain (ConsortiumBlockChains)
Industry Blockchain: Multiple preselected nodes are designated within a certain group as bookkeepers, and the generation of each block is jointly performed by all preselected nodes. Decision (pre-selected nodes to participate in the consensus process), other access nodes can participate in transactions, but do not participate in the accounting process(Essentially, it is still custodial accounting, but it becomes distributed accounting. How to pre-select the number of nodes and how to decide the bookkeeper of each block becomes the main risk point of the blockchain). Anyone else can pass the Blockchain open API for limited query.
3. Private Blockchain (privateBlockChains)
Private Blockchain: Only uses the general ledger technology of the blockchain for accounting. It can be a company or an individual, and has exclusive access to the writing of the blockchain. With access permissions, this chain is not much different from other distributed storage solutions. At present (Dec2015), conservative giants (traditional finance) want to experiment with private blockchains, while public chain applications such as Bitcoin have been industrialized, and private chain application products are still being explored.
4. Sidechain (Sidechain)
Sidechain is a blockchain used to confirm data from other blockchains. Through the two-way peg (TwoWayPeg) mechanism, various assets such as Bitcoin and Ripple coins can be Transfers are realized on different blockchains at a certain exchange rate.
What is the structure of blockchain?
1. Basic network layer: The basic network layer consists of a data layer and a network layer. The data layer includes underlying data blocks and related data encryption and timestamp technologies; the network layer includes distributed networking mechanisms, Data dissemination mechanism and data verification mechanism, etc.
2. Intermediate protocol layer: The intermediate protocol layer consists of a consensus layer, an incentive layer, and a contract layer. The consensus layer mainly includes various consensus algorithms of network nodes; the incentive layer integrates economic factors into the blockchain technology system. , mainly including the issuance mechanism and distribution mechanism of economic incentives; the contract layer mainly includes various scripts, algorithms and smart contracts, which is the basis of the programmable features of the blockchain.
3. Extension layer: This layer is similar to a computer driver and is designed to make blockchain products more practical. There are currently two categories. One is various trading markets, which are important channels for exchanging legal currency for cryptocurrency. They are simple to implement, get money quickly, and have low costs, but the risks are also high. The second is the expansion implementation in a certain direction. For example, based on the Yishu side chain, it can provide customized services for third-party publishing organizations, forum websites and other content producers.
4. Application service layer: As the most important link in the blockchain industry chain, the application service layer includes various application scenarios and cases of blockchain, including programmable currency, programmable finance and programmable society.
The above are the blockchain classifications brought to you by the editor? What is the structure of blockchain? of the entire content.

『五』How to classify blockchain

What are the characteristics of public chain, private chain and consortium chain? Blockchains are divided into three categories based on access mechanisms: public chains, private chains and alliance chains. Other types of blockchains may be born in the future. The public chain is open and transparent. Any individual or group in the world can send transactions on the public chain, and the transactions can be effectively confirmed by the blockchain. Everyone can compete for accounting rights. The Bitcoin blockchain is a typical example of public chainsurface. The alliance chain is semi-public. It is a blockchain used within a certain group or organization. Several nodes need to be pre-designated as bookkeepers. The generation of each block is jointly decided by all pre-selected bookkeepers. Other nodes can trade, but do not have bookkeeping rights. Private chains are completely closed. Only blockchain technology is used for accounting. The accounting rights are not public, and only internal transactions are recorded, which is exclusive to the company or individual.

『Lu』 Types of Digital Currency

The abbreviation of digital currency is DIGICCY, which is the abbreviation of "Digital Currency" in English. There are many types of digital currencies, starting from the original Bitcoin Currencies have developed to the point where digital currencies in various cities are complex and diverse, such as Litecoin, Dogecoin, Yuanbao Coin, etc. If you want to learn more about it, you can go to BTC100, which has a rich variety of digital currencies.
