『一』The reason why the blockchain connection verification failed

The strategy failed. The reason for blockchain connection verification failure is policy failure. Blockchain (English: blockchain or blockchain) is an intelligent peer-to-peer network that uses a distributed database to identify, disseminate and record information.

『二』How to identify the real blockchain digital currency

Whether a certain digital currency is a valuable currency is basically in the "angel round" stage at present. In other words, there are three judgment criteria, one is the team, the other is the economic model, and the third is industry demand.

The randomness of the team is too great and will not be discussed here. This article first conducts a detailed analysis of the economic model of digital currency. In subsequent articles, the author will analyze some digital currencies according to different industries.

Strictly speaking, the economic model involved in this article is not completely equivalent to the concepts described in economics. Specifically refers to the consensus mechanism and incentive mechanism of currency in digital currency.

1. Consensus Mechanism

The consensus mechanism is the strategy and method for each node in the blockchain system to reach agreement, and should be flexibly selected according to the system type and application scenarios.

Commonly used consensus mechanisms mainly include PoW, PoS, DPoS, PBFT (and their variants), etc. In addition, based on the different application scenarios of blockchain technology and the characteristics of various consensus mechanisms, this article evaluates the technical level of various consensus mechanisms according to the following dimensions:

a) Compliance supervision: whether it supports Super The authority node supervises the nodes and data of the entire network;

b) Performance efficiency: the efficiency of the transaction reaching consensus and being confirmed;

c) Resource consumption: the CPU, Network input, output, storage and other computer resources;

d) Fault tolerance: the ability to prevent attacks and fraud.

1 Industry background

Find industry pain points: Asset management requires a professional team and knowledge, but most digital currency investors now do not have it; digital The currency market fluctuates greatly, and investors are unable to preserve the value of their assets when the market falls.

2 Own advantages

Having been deeply involved in the stock and futures markets for many years, it has a mature and high-quality asset management team; the AI ​​big data team has strong technical strength.

3 Market Research

After conducting market research, it is estimated that the market value of asset management will be approximately US$1 billion in the next five years.

4 Total amount of digital currency

After considering the expected market value of asset management, development cycle and difficulty, consider issuing 2 billion digital currency XT based on Ethereum ERC20, and will never issue more .

5 Distribution method

Early investors hold 10%, the team holds 20%, business operations 10%, community construction 10%, and investors hold 50%.

6 numbersSub-currency release/repurchase mechanism

The release mechanism is divided into three categories:

Category 1: All currency holdings for business operations are fully unlocked, and their use is limited to business and operational activities;< /p>

The second category: The release mechanism of the community construction part is that when community members publish exclusive information, cooperation platforms publish exclusive project progress, etc., according to the number of participating IDs, a corresponding proportion of XT is released (the publisher and the participant each receive 50%) until all releases are completed (after the releases are completed, subsequent rewards will come from the platform profit pool);

The third category: Investors hold mainstream digital currencies and conduct asset management in the platform. According to the exchange ratio , releasing a certain amount of XT, and early investors and the team hold part of it simultaneously, and unlock it in proportion;

The buy-back mechanism is: 50% of the profit (calculated in XT) is returned to currency holders; the remaining Enter the platform profit pool, and 50% of the XT in the profit pool will be destroyed on a monthly basis until the total amount of XT reaches 1 billion; the rest will be used as the platform ecological construction fund;

7 Digital Currency Rights

Profit sharing: If you hold XT, you are a platform user and can enjoy 50% of the platform’s profits;

Platform governance: Participate in platform activities and enjoy XT rewards and airdrops from other project parties;< /p>

Function customization: Based on the platform’s AI big data, investors can purchase services optimized for personal trading strategies

『三』 At what stage does identity verification occur in blockchain cross-border transactions?

Transaction initiation stage.
Blockchain development is still in its emerging stage, and it will take time to cultivate talents. Relying on the underlying technical characteristics, traceability and transactions can be carried out safely, efficiently and at low cost.
Blockchain is a database with data hash verification function. Blocks are data blocks. Data blocks are combined into a chain structure in chronological order, and cryptographic algorithms are used to record data in a distributed manner. In an accounting manner, the reliability of the database is collectively maintained, and all data blocks are connected in chronological order to form a blockchain.

『四』How to verify the integrity of blockchain evidence data through micro-copyright

"Regulations on Several Issues Concerning the Collection, Extraction, Review and Judgment of Electronic Data in Criminal Cases" No. Article 5 stipulates that the integrity of electronic data can be protected by calculating electronic data integrity check values.

To verify the integrity of electronic data, verification algorithms such as hash values ​​are generally used.

Microcopyright uses the SHA-512 hash algorithm, timestamp service, and PBFT consensus algorithm to encrypt the original data and generate the certificate subject, certificate time, certificate process, and content. The unique corresponding digital fingerprint is encrypted and stored on the blockchain, effectively ensuring the integrity of the certificate data.

Users enter the registration number of the certificate data and upload the original file through the "Verification Preservation" on the official website of Micro Copyright. The system automatically checks the hash value of the uploaded file and the hash value of the original certificate data. Compare, if the evidence data is storedIf the uploaded file is complete and correct, it will pass the verification; otherwise, it will not pass.

『Wu』How to verify and query the blockchain evidence data through micro-copyright

Through the registration number on the evidence collection certificate, Blockchain queries can also be conducted directly on the official website of Yibaoquan, the notary office and the arbitration committee, including relevant information such as the preservation subject, preservation timestamp, Guangzhou Internet Court evidence number, blockchain hash value, etc., to ensure the blockchain evidence storage data transparency and traceability.

『Lu』 How to use blockchain to solidify, access and verify evidence to improve the effectiveness of evidence

Using blockchain to solidify, access, and verify evidence can improve the effectiveness of evidence and prevent evidence from being tampered with or lost. The following are the specific steps:

1. Evidence solidification: record the hash value of the evidence on the blockchain, and use the non-tamperability and decentralization characteristics of the blockchain to ensure the integrity of the evidence sex and authenticity. For example, a public chain or a private chain can be used to solidify evidence. The public chain can better ensure the fairness and transparency of the evidence, while the private chain can better protect the privacy of the evidence.

2. Evidence access: Utilize the distributed storage characteristics of the blockchain to store evidence on multiple nodes to ensure the reliability and durability of the evidence. For example, decentralized storage protocols such as IPFS (InterPlanetary File System) can be used to store evidence, and smart contracts can be used to control access rights to evidence.

3. Evidence verification: Taking advantage of the decentralized and open and transparent features of the blockchain, the authenticity and integrity of the evidence can be easily verified. For example, you can use a blockchain browser to view the hash value or transaction record of the evidence, or you can use smart contracts to verify the authenticity and integrity of the evidence.

It should be noted that the use of blockchain for evidence solidification, access, and verification needs to comply with relevant laws, regulations, and privacy protection principles. At the same time, the security and reliability of the blockchain technology itself need to be considered.
