The underlying technology framework of blockchain
Publish: 2021-05-20 15:47:58
1. The underlying architecture of laikelib blockchain technology is a blockchain technology system developed by the blockchain Technology Laboratory of Shanghai Heshu Software Co., Ltd. for details, you can go to the official website of laikelib.
2. Just to learn a little, Heshu software was founded in 2017. It has its own blockchain technology laboratory, focusing on blockchain technology scenarios and application development. For example, the underlying architecture of laikelib blockchain allows users to develop their own independent applications and systems on the chain, which is similar to Ethereum. The advantages of laikelib are small capacity, short block out time of 2 seconds, diversification and independent research and development. The response is still good, and they have set up a technical team composed of experts in the fields of data science, blockchain, cryptography and data analysis. The others are not clear. I hope they can help you and hope to adopt them!
3. Laikelib main chain: the main chain of laikelib mainly deals with the interaction between the application business model and the application scenario. Laikelib side chain: around the main chain, any application system can be developed in the side chain for users to use.
4. Aggregation chain refers to the innovative introction of "alliance chain + cross chain + public chain" aggregation chain technology architecture on the basis of long-term accumulated alliance chain technology, so as to realize the efficient, safe and low-cost flow of data and assets, and then practice the historical mission of enabling distributed economy.
5. After that, the picture is very smooth, that is, there is a little action delay. Although the computer configuration is not high, it can still drive the dragon fly to kill, but the rest of the boss on the ground are single kill, fast 100 dog teeth trap
6. The current mainstream blockchain architecture includes six layers: network layer, data layer, consensus layer, incentive layer, contract layer and application layer. The positions of data layer and network layer are exchanged in the figure, and the main uses will be described in the next section
network layer: blockchain network is essentially a P2P (peer-to-peer) network. The resources and services in the network are distributed on all nodes, and the information transmission and service implementation are directly carried out between nodes, without the intervention of intermediate links and servers. Each node not only receives information, but also generates information. Nodes synchronize information by maintaining a common blockchain. When a node creates a new block, it notifies other nodes in the form of broadcast. After receiving the information, other nodes verify the block and create a new block on the basis of the block, So as to achieve the role of the whole network to jointly maintain a bottom ledger. Therefore, the network layer will involve the design of P2P network, propagation mechanism and verification mechanism. Obviously, these designs can affect the confirmation speed of block information. The network layer can be used as a research direction in the scalable scheme of blockchain technology
data layer: the underlying data of blockchain is a data structure of block + linked list, which includes data block, chain structure, timestamp, hash function, Merkle tree, asymmetric encryption, etc. Among them, data block and chain structure can be used as the improvement direction of data layer research in the extensible scheme of blockchain technology
consensus layer: it is the basis for highly dispersed nodes to reach a fast consensus on the effectiveness of block data. The main consensus mechanisms include pow (proof of work), POS (proof of stake), dpos (delegated proof of stake) and pbft (Practical Byzantine fault tolerance), They have always been the highlight of the scalable solution of blockchain technology
incentive layer: it is a common mining mechanism, which is used to design certain economic incentive model and encourage nodes to participate in the security verification of blockchain, including the design of issuance mechanism and allocation mechanism. Improvements at this level do not seem to be directly related to blockchain scalability
Contract layer: mainly refers to various script codes, algorithm mechanisms and smart contracts. Strictly speaking, this layer of the first generation blockchain is missing, so they can only trade, and can not be used in other fields or other logical processing. The emergence of the contract layer makes it a reality to use blockchain in other fields. This part of Ethereum includes EVM (Ethereum virtual machine) and smart contract. The improvement of this level seems to provide a potential new direction for the scalability of the blockchain, but it does not seem to be directly related to the application layer in terms of structure
it is the display layer of the blockchain, including various application scenarios and cases. For example, Ethereum uses truffle and Web3 JS. The application layer of blockchain can be mobile terminal, Web terminal, or integrated into the existing server, taking the current business server as the application layer. The improvement of this level also seems to provide a potential new direction for the expansion of blockchain, but structurally, it doesn't seem to be directly related
the Xueshuo innovation blockchain Technology Workstation of Lianqiao ecation online is the only approved "blockchain Technology Specialty" pilot workstation of "smart learning workshop 2020 Xueshuo innovation workstation" launched by the school planning, construction and development center of the Ministry of ecation of China. Based on providing diversified growth paths for students, the professional station promotes the reform of the training mode of the combination of professional degree research, proction, learning and research, and constructs the applied and compound talent training system.

7. I know that
8. Yes, the real blockchain technology of Heshu laikelib has the characteristics of blockchain. "As long as the Internet exists, the underlying framework of Heshu laikelib blockchain technology will never disappear.".
9. The advantages and number of blockchain in information security are summarized by the blockchain technical team in the following three aspects: 1. Using highly rendant database to ensure the data integrity of information; 2. Using the relevant principles of cryptography to verify the data and ensure that it can not be tampered with; 3. In terms of power management, using multiple private key rules to control the access power
