What are the architectural models of blockchain technology?

The architectural model of Jinwowo analysis blockchain technology is as follows:

1. Data layer.

The data layer encapsulates the underlying data blocks and related technologies such as data encryption and timestamping.

2. Network layer.

The network layer includes a distributed networking mechanism, a data propagation mechanism and a data verification mechanism.

3. Consensus layer.

The consensus layer mainly encapsulates various consensus algorithms of network nodes;

4. Incentive layer.

The incentive layer integrates economic factors into the blockchain technology system, mainly including the issuance mechanism and distribution mechanism of economic incentives.

5. Contract layer.

The contract layer mainly encapsulates various scripts, algorithms, and smart contracts, which is the basis for the programmable characteristics of the blockchain.

6. Application layer.

The application layer encapsulates various application scenarios and cases of blockchain.

Network mutual insurance is a variant of mutual insurance in China's special national conditions and the current special regulatory environment, and it is a phased product. Although the China Insurance Regulatory Commission (CIRC) issued the Trial Measures for the Supervision of Mutual Insurance Organizations last year, the various regulations are basically based on foreign mutual insurance models. However, the licence has not been issued for a long time.

However, some pioneers in China were worried about missing the opportunity, so they began to explore in the name of online mutual aid after improvement. In addition to not having a license and not having a registered insurance company, their model has the following characteristics:

First: Reach the masses, not the same people. In this way, the user group is expanded, which is conducive to the rapid accumulation of users, but it loses the characteristics of the same kind of people;

Second: no upfront fees, or small upfront fees, rather than annual payments according to the actuarial model. This lowers the threshold for customer acquisition, but the follow-up payment willingness and retention rate of the attracted users will be reduced.

Third, the subject matter of protection is mainly critical illness and accidental injury, which are relatively standardized, which is conducive to risk control by mutual aid platforms. However, the flexibility of mutual insurance has not yet been brought into play.

The platform of Tongxinshe adopts the latest blockchain as the underlying technical architecture, which is still reliable.

The architecture of blockchain technology includes the following aspects:

Decentralized network: The core of blockchain technology is decentralization, and its network structure is different from the traditional centralized network structure, which realizes the transmission and verification of data through a point-to-point way, so as to achieve the purpose of decentralization.

Consensus mechanism: The consensus mechanism is an important means to ensure data security and reliability in the blockchain network, and the consensus mechanism can ensure the data consistency between all nodes in the blockchain network. Common consensus mechanisms include proof-of-work, proof-of-stake, and stake authority.

Smart contracts: Another important component of blockchain technology is a smart contract, which is a computer program that is able to automatically execute and verify contracts, enabling programmable and automated transactions on a blockchain network. Distributed Storage:

Distributed storage is another important part of blockchain technology, which improves the security and reliability of data by storing data on various nodes of the network to achieve distributed storage and backup of data.

Common numerical characteristics include expectation, variance, standard deviation, etc., which can be used to describe the central trend of random variables, filial piety, dispersion degree and other characteristics, and can also be used for probability calculation and risk analysis.

The three levels in blockchain technology are described below:

Protocol layer. The so-called protocol layer refers to the lowest level of technology. This layer is usually a complete blockchain product, similar to our computer's operating system, which maintains network nodes and only provides APIs for calling.

Usually the official will provide a simple client (commonly known as wallet), this client wallet function is also very simple, can only establish an address, verify the signature, transfer payment, check the balance of the good amount, etc.

Extension layer. This level is similar to a computer's driver, and is intended to make blockchain products more practical.

It should be covered with a layer of lead for potatoes.

This level is similar to various software programs in computers, and it is a product that ordinary people can really use directly, and it can also be understood as the browser side of the BS architecture product. The application at this level is almost blank at present.
