1. For example, I borrow money from you in a village. Normally, if I am afraid that you will not repay the money, I can find an intermediary recognized by everyone, such as the village head as the guarantor, and sign an IOU. In this way, if you default at that time, I can find an intermediary to prove that you really owe me money, But there are two problems: 1. What if the village head finds out that his long lost son colludes with him to cheat you on money? 2. What if the middleman dies on the spot the next day! This is about trust and security. If the method of
blockchain is to provide you with the certificate of the whole village (distributed), so that everyone knows about it and the other party can't default on it. Second, even if a small number of people or village heads deny (some nodes commit crimes) that they have lost the IOU or tampered with the content, there will still be others to make the basis
above, explain the two problems of building owners: 1. Decentralization, because the account book records are not centralized in the hands of each participant, and you will get paid if you save and keep accounts. 2. Since I can get rewards by saving and keeping accounts, can I just keep accounts instead of storing them? If you have a
mining pool, you can keep accounts for it and store it for you. In this way, you can still get good rewards. There are only a few mining pools in the world, so they are centralized
2. That is, no one can control, not be controlled by the living center of a living group. Therefore, it can not be used as legal tender recognized by the state. There are a group of money speculators who argue that
virtual currency will replace paper money every day. It's all bullshit. We must pay attention to investment risks. Now there are many pyramid schemes with virtual
digital currency gimmicks to cheat money
3. Policies and regulations
4. HNB community set up a GMH, the policy and decision were voted by decentralized participants, executed by smart contract, without human intervention. Major issues shall be discussed and voted by the general meeting of all community members. The full-time boards (development board, reserve board and arbitration board) authorized by GMH perform their respective ties. It effectively protects the rights and interests of all.
5. bitcoin, Leyte coin, dogcoin, Diandian coin, American card coin, bitstock, dark coin, black coin, Ruibo coin, Malaysian coin, Mediterranean coin, Yuanbao coin, Zhaocai coin, sand coin, network gold
6. Anti counterfeiting, such as frog coin and Weilian the source and process of frozen food monitoring of final procts such as imported milk powder and luxury goods: red wine, bags and refrigerators, because it is impossible to cheat by writing into the blockchain Back modification is being implemented or has been implemented (only the chain's partners are very strong)
smart contract or intellectual property rights, such as publishing a song. In the blockchain, you own the song, use the smart contract to sell and protect the property rights, such as Neo and Ethereum. Game development or program development: for example, cryptokitties are free to breed and trade different kinds of cats without age or rarity (the closer the age is, the more expensive it is)
the evolutionary version of ICO IPO raised $40 billion in 2017, which is the securities of any company or indivial to support its development of e-money Platform (polymeth)
free trade of game items under development
7. In addition to bitcoin, Ruitai, Laite and Ruibo, the mainstream digital currencies have certain liquidity, other Shanzhai currencies basically have no liquidity. The related application is even more deficient, just staying in the theoretical stage
of course, it is not ruled out that large institutions will develop liquid digital currencies in the future.
8. In fact, this kind of digital finance is not reliable. Now the country is only in the trial stage, and it is not reliable.
9. Does Tianjin have a lawyer who knows bitcoin? This should be understood. Bitcoin lawyers.
