How to test blockchain
At present, whether a digital currency is a valuable currency basically belongs to the "angel wheel" stage. There are three criteria to determine whether a digital currency is a valuable currency: one is the team, the other is the economic model, and the third is the instry demand
The randomness of theteam is too great, so we will not discuss it here. This paper first makes a detailed analysis of the economic model of digital currency. In the following article, the author will analyze some digital currencies according to different instries
Strictly speaking, the economic model involved in this paper is not completely equivalent to the concept described in economics. Especially in digital currency, currency consensus mechanism and incentive mechanism Consensus mechanism is the strategy and method for each node in the blockchain system to reach an agreement, which should be selected flexibly according to the different types of system and application scenarioscommon consensus mechanisms include pow, POS, dpos, pbft (and its variants), etc. In addition, based on the different application scenarios of blockchain technology and the characteristics of various consensus mechanisms, this paper evaluates the technical level of various consensus mechanisms according to the following dimensions:
A) compliance supervision: whether super permission nodes are supported to supervise the nodes and data of the whole network
b) performance efficiency: the efficiency of reaching a consensus and being confirmed
Resource consumption: CPU, network input and output, storage and other computer resources consumed in the process of consensusd) fault tolerance: the ability to prevent attacks and fraud
1 instry background
looking for Instry pain points: asset management needs professional team and knowledge, but now most digital currency investors do not have it; The fluctuation of digital money market is huge, and investors can't keep the value of assets in the falling market
2 own advantages
in the stock and futures markets for many years, has a mature and high-quality asset management team; AI big data team has strong technical strength
3 Market Research
after market research, it is estimated that the market value of asset management will be about US $1 billion in the next five years
4 total amount of digital currency
after considering the expected asset management market value, development cycle and difficulty, we will consider issuing 2 billion pieces of XT based on Ethereum erc20 digital currency, and never issue additional ones
5 allocation method
early stage investors hold 10%, teams hold 20%, business operation 10%, community construction 10%, and investors hold 50%
6 digital currency release / repo mechanism
the release mechanism can be divided into three categories:
the first category: the money holding part of business operation is fully unlocked, and the purpose is limited to business and operation activities
the second type: the release mechanism of community construction is that community members release exclusive information, cooperation platform release exclusive project progress and so on. According to the number of participating IDS, the corresponding proportion of XT is released (publishers and participants get 50% each) until all the releases are completed (after the release, the follow-up reward comes from the platform profit pool)
the third category: investors hold the mainstream digital currency, conct asset management in the platform, release a certain amount of XT according to the exchange ratio, and the early investors and the team hold part of it synchronously and unlock it according to the proportion
the repo mechanism is: 50% of the profit (in XT) will be returned to the holder; The rest goes into the platform profit pool, and 50% of XT in the profit pool is destroyed monthly until the total number of XT is 1 billion; The rest will be used as platform ecological construction fund
7 digital currency equity
profit sharing: holding XT is for platform users, and they can enjoy 50% of platform profits
platform Governance: participating in platform activities, enjoying XT awards and airdrop activities of other project parties
function customization: Based on platform AI big data, investors can purchase services optimized for indivial trading strategies
Through the record number on the forensics certificate, you can also directly query the blockchain on the official websites of easy security, notary office and Arbitration Commission, including the preservation subject, preservation timestamp, Guangzhou Internet court evidence number, blockchain hash value and other relevant information, so as to ensure the openness, transparency and traceability of blockchain storage data
jump out of the verification interface, click the return button in the upper left corner, and then upgrade to the latest version to refresh the node. Or uninstall again and restore the account with mnemonics Refresh node] in free communication, the + sign in the upper right corner, "node detection & quot;
Article 5 of the provisions on collection, extraction, examination and judgment of electronic data in handling criminal cases stipulates that the integrity of electronic data can be protected by calculating the integrity check value of electronic data
to verify the integrity of electronic data, hash value and other verification algorithms are generally used
micro right encrypts the original data through sha-512 hash algorithm, time stamp service and pbft consensus algorithm, generates a unique corresponding digital fingerprint for the subject, time, process and content of the certificate, and encrypts and stores it on the blockchain to effectively guarantee the integrity of the certificate data
users can input the record number of the stored data and upload the original file through the "verification preservation" on the official website of the micro right. The system automatically compares the hash value of the uploaded file with the hash value of the original stored data. If the stored data and the uploaded file are complete, they pass the verification, otherwise, they fail< br />
