Which is the advantage of digital currency
digital currency is characterized by low transaction cost, fast transaction speed and high anonymity
1, low transaction cost
compared with traditional bank transfer, remittance and other ways, digital currency transaction does not need to pay fees to the third party, and its transaction cost is lower, especially compared with the cross-border payment that provides high handling charges to payment service providers
2. Fast transaction speed
the blockchain technology used in digital currency has the characteristics of decentralization. It does not need any centralized organization similar to the clearing center to process data, and the transaction processing speed is faster
3. High anonymity
in addition to the point-to-point transaction without intermediary participation, one of the advantages of digital currency compared with other electronic payment methods is that it supports remote point-to-point payment, and it does not need any trusted third party as intermediary, Both sides of the transaction can complete the transaction in a completely unfamiliar situation without mutual trust, so they have higher anonymity, which can protect the privacy of traders. But at the same time, it also creates convenience for cyber crime, which is easy to be used by money laundering and other criminal activities
extended data
the impact of digital currency:
digital currency is a double-edged sword. On the one hand, the blockchain Technology it relies on realizes decentralization and can be used in other fields except digital currency, which is one of the reasons why bitcoin is popular
On the other hand, if digital currency is widely used by the public as a kind of currency, it will have a huge impact on the effectiveness of monetary policy, financial infrastructure, financial market and financial stability1. Enjin (enj)
in the near future, the game instry is the instry most likely to adopt blockchain on a large scale. Enjin coin is the cryptocurrency of virtual goods created by Enjin. Enjin is the "largest online gaming community platform" with more than 250000 gaming communities and 18.7 million registered gamers
Cardano (ADA)compared with Ethereum, EOS and Tron, Cardano is the third generation of decentralized app (DAPP) and smart contract platform. Cardano's design philosophy has the following points:
scalability: with the growth of users, the transaction processing speed is not affected or even faster, such as P2P protocol
interoperability: in the future, there will be countless devices connected to each other, instead of only connecting and forwarding through routers. All kinds of devices can communicate directly through standard general protocol
Sustainability: like bitcoin, Cardano project will not be controlled and influenced by a certain company or organization, which is a safe, decentralized and sustainable development platform
With the popularity of sto (security token offers), Nash also plays an important role. Nash is a kind of registered security token. In the past, Nash participated in and led the development of many projectsNash exchange is a decentralized exchange. If you hold nex token, you can calculate the dividend here
4. Basic attention token (BAT)
bat mainly solves the problem of advertising:
user information is abused: large companies such as Google and Facebook track and use user information and behavior, and sell without the knowledge of users
the effect of advertising is restrained: middlemen earn most of the fees, a large number of advertisements are blocked by users using software, and advertisements are fake
in the past six to 12 months, the number of publishers using the brand browser (Note: the brand browser supports bat token) has grown rapidly, and almost no blockchain ecosystem has grown so fast
5, chainlink (link)
chainlink mainly solves the problem that each blockchain has and the smart contract cannot obtain external data. In order to introce external data into the blockchain, the concept of Oracle is proposed in smart contract
companies including Google are supporting the development of chainlink. Here is a list of chainlink partners
one of the main problems of chainlink is similar to Ethereum. The development team has reserved 650 million link tokens, while only 350 million are in circulation at present
Ethereum (ETH)Ethereum has long occupied the second place in the top 100 cryptocurrencies. Its ecology is so big that we can't call it altcoin now. To tell you the truth, I'm not optimistic about Ethereum in the long run, but it will flourish in the short run
1. Secure
transaction of cryptocurrency on the decentralized platform of blockchain, the E-wallet used by it is authorized to send and receive cryptocurrency by the cryptosystem using the unique public key and private key. And the account does not need to be identified by a third party, so outsiders can not know the identity of the trader
2. Tamper proof
after the transaction on the blockchain is confirmed, it is tamper proof, and this kind of data is traceable, so the illegal elements can't cheat by deleting or modifying the records
you can learn about cryptocurrency through some media platforms, so I won't go into details here.
the United States is the country with the most coal in the world, because there are many mountains with a lot of coal reserves in their country for example, these mountains with rich coal deposits have been extending from Canada to Alabama for more than 3200 kilometers. It's hard to imagine that such a long mountain line is rich in coal, accounting for 27.6% of the world's coal, so the United States is the country with the largest coal reserves{ RRRRR}
even with such abundant coal resources, we should make rational use of them and maximize their utilization of course, the surrounding ecological environment should also be taken into account, so as not to cause serious environmental problems. In fact, many animals and plants around these mining areas have been greatly damaged
