What are the blockchain classifications? What is the blockchain structure?
The concept of the blockchain has been quite popular in recent times. It comes from the implementation of cryptocurrencies such as Bitcoin, but the technology has been gradually applied in various fields. So do you know what the blockchain classification is? What is the blockchain structure? Let's take a look at the decoration home decoration network Xiaobian.
What are the blockchain classifications?
1 , public blockchain ( PublicBlockChains)
A public blockchain means that any individual or group in the world can send a transaction, and the transaction can obtain a valid confirmation of the blockchain, and anyone can participate in the consensus process. The public blockchain is the earliest blockchain and is the most widely used blockchain . The virtual digital currency of each bitcoins series is based on the public blockchain . There are only one block corresponding to this currency in the world. chain.
2 , joint (industry) blockchain ( ConortiumBlockChains)
Industry blockchain: multiple pre-selected nodes are designated as billers within a group. The generation of each block is determined by all pre-selected nodes (pre-selected nodes participate in the consensus process), and other access nodes can participate in transactions, but But ask the accounting process ( essentially managed accounting, just become distributed accounting, how many pre-selected nodes, how to determine the biller of each block becomes the main risk point of the blockchain), anyone else can The qualified query is performed through the API of the blockchain opening .
3 , private blockchain ( privateBlockChains)
Private blockchain: only use the blockchain general ledger technology for accounting, it can be a company or an individual, and enjoy the write permission of the blockchain. This chain is not much different from other distributed storage solutions. the difference. At present (Dec2015) conservative giants (traditional finance) are trying to experiment with private blockchains , while public chain applications such as bitcoin have been industrialized, and private-chain applications are still being explored.
4 , side chain ( Side chain )
The side chain is a blockchain for confirming data from other blockchains . The two-way hook ( TwoWay Peg ) mechanism enables multiple assets such as Bitcoin and Ripple coins to be transferred at different exchange rates on different blockchains.
What is the blockchain structure?
1, base Network layer: The network layer of a data base layer, network layer, wherein the underlying layer includes the data block and associated data and time stamp data encryption techniques and the like; the network layer comprises a distributed networking mechanism, data propagation mechanism And data validation mechanisms, 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 are the basis of the blockchain programmable features.
3 , the extension layer: This level is similar to the computer driver, in order to make the blockchain products more practical. At present, there are two types, one is the various trading markets, which is an important channel for the exchange of legal currency into cryptocurrency. It is simple to implement, fast in money, low in cost, but also risky. The second is to achieve the expansion of a certain direction, such as based on the billion side chain, can provide customized services for third-party publishers, forum sites and other content producers.
4. Application service layer: The application service layer is the most important link in the blockchain industry chain, including various application scenarios and cases of the blockchain, including programmable currency, programmable finance and programmable society.
The above is what is the blockchain classification that Xiaobian brings to you ? What is the blockchain structure? For the full content, I believe that after reading this article , you have a basic understanding of blockchain classification and blockchain composition.
