The smart contract has been written for a long time
if they can add changes, the description is centralized
the contract is written into the Ethereum smart contract, which is a contradiction sentence
the financial customer service doesn't understand, which is very unreliable

with the recent sharp fluctuation of currency prices, a new profession, commonly known as "brick moving", is graally emerging in the circle. These brick moving workers pay close attention to the major bitcoin and Ethereum transactions every day. Once they find the price difference, they buy bitcoin and Ethereum from the low price and sell them from the high price to make profit

with the increasing number of bitcoin and Ethereum transactions, according to incomplete statistics, the number of current international mainstream bitcoin transactions is graally increasing. Different from A-share and other stock markets, the stock price is globally unified. For example, the stock price of technology has the only pricing in Hong Kong stock market. However, the prices of bitcoin and Ethereum are determined by the transaction itself. Because Ethereum has a large number of transactions and different transaction volumes, the transaction price is very likely to fall. When the price fall is large, it can even reach 8% ~ 10% of Ethereum's price. At this time, many porters have the opportunity to move bricks. The so-called "brick" of moving bricks refers to Ethereum. Porters buy Ethereum from the low price and then transfer it to the high price to get the price difference

for example, the recent sharp fluctuations in bitcoin and Ethereum markets are a good time to move bricks. Generally speaking, as long as there is a price difference of 5-50 yuan between bitcoin and Ethereum, it is worth moving bricks. However, moving bricks also requires certain transfer costs and labor costs. Sometimes, the withdrawal of bitcoin purchased from low price will not arrive so quickly. In order to speed up the transaction speed and rece the risk of price fluctuation, the porter usually has a turnover of bitcoin. For example, after purchasing bitcoin and Ethereum from a, he immediately transfers the same amount of bitcoin from his wallet to B for sale, After the completion of bilateral transactions, graally withdraw the funds into their wallets, waiting for the next time to move bricks. If you have both cash and bitcoin and Ethereum, it's the safest. You can pay at a low price and register at a high price, and then trade at the same time. The transaction can be completed in a few seconds. At this time, there is little risk in moving bricks, and what you get is pure profit. When the price of bitcoin fluctuates greatly, part of the price response is not so fast, and the profit of moving bricks is the highest

Yes, refer to the interaction between contracts. Digital currency exchange platform for example, I am trying to sign a smart contract from another factory contract and then redeploy the address of the new smart contract. However, the address it returns is the transaction hash, not the contract address. I believe this is because when the address is returned, the contract has not been exploited. When I deploy the smart contract with Web3, it seems that it will not output the contract address until the smart contract is deployed

let's first talk about the calculation method of "item": the difference between the number of items on both sides, such as 180.5 items on the black side and 180.5 items on the white side, is that the white side wins 7.5 items, because the black side has to post 7.5 items first
let's talk about the calculation method of "sub": half of the intersection point is 180.5 + 3 + 3 / 4 (half of 7.5 mesh). If one party wins by more than this number, the number of sub winning is the difference between the number of sub winning party and 180.5 + 3 + 3 / 4, which is the same as the above example, that is, white party wins 3 + 3 / 4.
