International block chain technology for the disabled

1. From the perspective of data, blockchain is a kind of distributed database or distributed shared general ledger. The "distributed" here is not only reflected in the distributed storage of data, but also reflected in the distributed records of data. From the perspective of effect, blockchain can generate a set of time sequence, tamper proof and trustworthy database
blockchain has four core technologies. The first one is block + chain, which is the most core and basic technology in blockchain. The second core technology is distributed structure. The ingenious design of blockchain structure is to let every node participating in data transaction record and store all data. The third core technology is asymmetric encryption algorithm, and the fourth core technology is script, which can be understood as a programmable smart contract.

A: application fields of blockchain technology

I. financial field

blockchain has great potential application value in international exchange, letter of credit, equity registration, stock exchange and other financial fields

Second, the Internet of things and logistics

blockchain can also be naturally combined in the field of Internet of things and logistics

through the blockchain, we can rece the logistics cost, trace the proction and transportation process of goods, and improve the efficiency of supply chain management

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

Fourthly, 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

In the field of insurance, insurance institutions are responsible for fund collection, investment and claim settlement, and often have higher management and operation costs

Sixth, the data stored on the public welfare field

blockchain is highly reliable and tamperable, which is naturally suitable for social public welfare scenarios

3. There are many blockchain content projects in China, such as coin, stemmit, etc. However, aqua is a relatively distinctive blockchain content project. The owner can download its DAPP to observe its difference from other projects. It is very creative in terms of publicity, objectives and functions. I hope it can help you.

4. All day trading... The website has no rest

5. ZCB disability fund will be officially launched on October 27, 2020. It is based on IPFs technology and is the currency mined by cloud mining machine. Compared with local mining, cloud mining machine mining can be used remotely through the network instead of mining machine. It can be said that it is a kind of cloud application or a kind of leasing and hosting service. The ownership of cloud mining machine does not belong to you, It's the miner rented to you. It's the 3.0 era of blockchain development and has epoch-making significance

the application of decentralized storage of ZCB disability fund has incomparable advantages, surpassing the former cloud storage, and further approaching our safe and efficient ideal storage state, which represents the future trend. In the current Internet world, users and websites communicate on the basis of HTTP protocol. With decentralization as a means, supplemented by incentive mechanism and consensus mechanism, reshape the way of communication between users and websites

only one billion ZCB has been issued in the world. All the mining machines have been excavated without pre excavation reservation. 10% of the handling fee is used for destruction until the remaining 50 million is used for global circulation. Limited free miner and free miner, with the increase of computing power, less and less ZCB is g out, and eventually the value of ZCB is increased to 50 times, 100 times, 1000 times or even higher, which will give back to the world
I can't give you an accurate answer to this question because digital currency covers too many aspects. There is also the possibility that many new cryptocurrencies are born or die every day. Now the world's more well-known digital currencies are bitcoin, dogcoin, Leyte coin, bitstock, reborn coin, Yuanbao coin, Diandian coin and so on. It is said that Ecuador, a small South American country, recently created its own official cryptocurrency

according to incomplete statistics, more than 200 counterfeit coins have been proced since 2014, and more than 100 have survived. The life cycle of Shanzhai coin is generally about 2-3 months. Because the purpose of some Shanzhai coins is to earn money without any innovation. When the price is high enough, the makers will sell a lot to cash out. Without the support of the makers, this kind of counterfeit money will eventually die

6. A successful blockchain project must have sufficient economic incentives and a deep understanding of human nature game theory in order to achieve dynamic balance.

The future blockchain world is a world that believes in economic incentives and economic rationality and is designed according to game theory.

7. In the future, in the process of continuous optimization of blockchain technology, it is bound to establish self-sufficient power supply for the community power grid.
