How to do and use blockchain in reality

I have seen your question. In which aspects can blockchain be applied? Below by the small series to answer for you

bitcoin is the first specific application of blockchain. It was proposed in a paper by one person or a group of people in 2008. Bitcoin uses blockchain to send digital messages to bitcoin, and the name of bitcoin is bitcoin, without the intervention of a third party middleman

1. Financial field: the application of blockchain technology in the financial instry can eliminate the third-party intermediary link, realize the point-to-point direct docking, so as to greatly rece the cost and quickly complete the transaction payment

2. Internet of things and logistics: blockchain can also be naturally combined in the field of Internet of things and logistics. Through blockchain, we can rece logistics costs, trace the proction and delivery process of goods, and improve the efficiency of supply chain management

3. Public service: blockchain is closely related to people's proction and life in public management, energy, transportation and other fields, but the centralization of these fields also brings some problems, which can be transformed by blockchain

4. In the field of digital right: through blockchain technology, works can be authenticated to prove the existence of text, video, audio and other works, and ensure the authenticity and uniqueness of ownership

5. In the field of insurance claims, insurance institutions are responsible for fund collection, investment and claims settlement, and often have higher management and operation costs. Through the application of smart contract, there is no need for the applicant to apply or the insurance company to approve. As long as the claim conditions are triggered, the automatic claim settlement of the policy can be realized

6. Public welfare field: the data stored on the blockchain is highly reliable and tamperable, which is naturally suitable for social public welfare scenarios. The relevant information in the public welfare process, such as donation project, collection details, fund flow, recipient feedback, etc., can be stored on the blockchain, and can be made transparent and public, which is convenient for social supervision

the above is for your reference only, hope you can adopt it, thank you

Do you understand every hero's personal skills in adventure and mining? The strength of a hero has a lot to do with his personal skills. Xiaobian brings you a complete collection of adventure and mining hero personal skills to help you have a comprehensive understanding of the advantages and disadvantages of skills. If you are interested, please accept it as soon as possible

Pure: the strongest and most practical skills at present, with King PVP one & quot; Dad;, It is the mainstream from the middle to the later stage. The pure advantage, first of all, is stability, second, pure disregard for defense and evasion, and finally, many copies are pure to pass, which is really IMBA. If we really want to talk about the pure weakness, it is the weakness in the early stage, but this stage is very short and harmless

Critical hit: the pioneers of the web version have summarized that the best lineup in the early stage is to attack critical hit stream first. It's true that in the early stage, when everyone's defense is not high enough, the benefit of critical hit is far greater than that of pure attack. In the middle and later stage, when everyone's defense is high enough, critical hit is more likely to catch chickens

Recovery: there are two kinds of recovery skills (self and opponent). The two kinds can be divided into four kinds (self maximum health value, self current health value, opponent's maximum health value, opponent's current health value). Recovery is different from blood sucking. You can recover blood whether you hit or not. In the two categories, those related to their own health value are suitable for PVP, and those related to their opponents are suitable for PVE (some levels must have this skill). I won't go into details

Blood sucking: blood sucking is very weak, yes, very weak. Among the skills of blood sucking, the only one that can be put on the table is the strategy of the two soldiers and guards. The others are weak. However, Zika has been eliminated in the middle and late period, and everyone's defense is high in the middle and late period, so it can't suck much blood. The specific weakness of blood sucking lies in the following points. First, blood sucking can only be profitable if it is hit. Second, most of the blood sucking cards have low absorption rate, with only two soldier guards as high as 200% (but there is no egg use). Finally, blood sucking is a tragedy if it is hit on high defense, with less damage and less blood sucking

Disabled (weak): pvppve are practical, there is only one disadvantage, not necessarily (except Xiuji)

Seal: at present, there are too few and weak seal cards, so people who use seal are very rare, but this does not mean that the seal is weak. In fact, the seal is very strong. In PVP, who seals the other party first will get a great advantage, but the disadvantage is also very obvious. Seal is not a must, and the early effect is very small, and it can not be printed, so we can only wait and see the seal card coming out later

Copy: the stronger the enemy is, the stronger I am

Percentages: there are two kinds of percentages: the opponent's current level and the upper limit of the opponent's level. Among them, the current level is relatively funny (only Satan is OK). The percentage PVP is very weak, and the PVE is passable. It is not recommended to use this skill

Slash: PvE and PvP are very awkward. If you can't hit a person, you don't say it first, and the damage after hitting a person is often lower than that of general attack. There are only two cards available in this series

Backwater: it's similar to chopping, but it's more embarrassing than chopping. It can be defined as useless

Multiplier: note that this multiplier has nothing to do with critical hit. Even 350% is not critical hit. Very simple skills are generally attached to other skills. They can be regarded as a common attack with high damage. They can be used in the early stage, but they are weak in the middle stage
