Ethereum usdt node

3.

1. The price of BTC and eth you see on this platform is not the real price against the US dollar, but the price in usdt, which is priced in OTC legal currency. Their ups and downs are all calculated in terms of usdt. All three of them are virtual currencies, just currency transactions, not real dollar prices

2. Usdt is a complete domestic counterfeit currency, formerly known as realcoin, but it has just changed its name. Realcoin is the second generation of domestic counterfeit currency, and the first generation is called chncoin Chinese currency. Both of them collapsed successively in 2013 and 2014

3. The actual value of usdt can be said to be equal to 0. Teda Company, which issued usdt, stopped providing any services to American citizens, that is to say, Teda Company could not provide usdt to us dollar

5. BTC is bitcoin, ETH is Ethereum, and usdt is a kind of token issued by American tether company in order to be equivalent to us dollar

6. Hello, directly select eth / usdt trading pair and use usdt to buy eth.

7. The price of BTC and eth you see is not the real price against the US dollar, but the price in usdt, which is priced in OTC legal currency. The rise and fall here are all calculated in terms of usdt, just currency transactions, not the real dollar price. 58coin, the king of contracts, is really good. There is no overnight fee, no flat rate, no pin. The advantage of the usdt perpetual contract is that it's very good. In the same account, the same contract currency can be long and short at the same time.

8. The essence of money is the general equivalent. It has the functions of value scale, circulation means, payment means, storage means and world currency. It is a certificate issued by the state or an organization authorized by the state for the distribution of goods in the whole society
it is different from the general equivalent: first, it is proced at different times; The general equivalent comes first and the currency comes second; Second, the general equivalent is not fixed in time, region and material quality, while the currency is fixed by gold and silver
money is a special commodity that acts as a general equivalent, a tool used as a medium of transaction, a storage value and a unit of account, and a material and symbolic appendage of people's commodity values. It includes not only currency in circulation, especially legal currency, but also all kinds of savings deposits. In the field of modern economy, only a small part of the field of currency is shown in the form of real currency, that is, the paper money or coins used in practice, and most transactions use cheques or electronic money. Currency area refers to the circulation and use of a single currency countries or regions
the essence of money at least includes the following aspects: first, money is issued by the state or institutions authorized by the state, which is the proct of the emergence of the state. Before the birth of the state, money can not be proced. Second, the scope of currency issuance is nationwide. Third, the object of money distribution is commodity (I use the concept of commodity here, and I emphasize here that only procts that realize exchange are commodities, and they are not commodities before they are exchanged with currency or other rights and interests.)
different currency areas need to introce the concept of exchange rate when they exchange currencies with each other. In modern economy, money plays a fundamental role. In macroeconomics, money is not only cash, but also cash plus a part of assets.

9. The following answers are expected to help you:
blockchain is a new application mode of computer technology such as distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm, etc
the so-called consensus mechanism is a mathematical algorithm to establish trust and obtain interests between different nodes in the blockchain system

in a narrow sense, blockchain is a kind of chained data structure that combines data blocks in chronological order in a sequential way, and it can not be tampered with and forged by cryptography

broadly speaking, blockchain technology uses blockchain data structure to verify and store data, uses distributed node consensus algorithm to generate and update data, and uses cryptography to ensure the security of data transmission and access It is a new distributed infrastructure and computing method to program and operate data by using intelligent contract composed of automated script code

advantages:

1) the algorithm is simple and easy to implement
2) there is no need to exchange additional information between nodes to reach a consensus
3) it takes a lot of cost to destroy the system< Disadvantages:

1) waste of energy
2) it is difficult to shorten the block confirmation time
3) the new blockchain must find a different hash algorithm, otherwise it will face bitcoin attack
4) it is easy to generate bifurcation and needs to wait for multiple confirmations
5) there is no finality, and checkpoint mechanism is needed to make up for it
blockchain is a kind of distributed shared accounting technology. What it needs to do is to enable all parties involved to establish a trust relationship at the technical level. Blockchain can be roughly divided into two levels, one is to do the underlying technology of blockchain; The second is to do the upper application of blockchain, that is, the transformation, optimization or innovative application based on blockchain
blockchain has been applied in several fields. In the first field of digital assets, in addition to some points and check-in cards we see, it also includes a variety of other assets, including the process of asset digitization
the second area is trade finance, because trade finance is originally a way of multi link participation and multi-party participation, blockchain can greatly improve the efficiency of the middle, making many of the original procts achieve the effect of substitutes
the third area uses equity, which is the company's equity. Like some regional equity trading centers, the purpose is to solve the convenience between equity and trading, and to make a relatively convenient circulation. At present, the multi center blockchain system can indeed improve efficiency and rece costs.
