2. bitcoin will set the balance of the address used for consumption (consumption address) to zero in business. When the amount to be paid is less than the available balance, it is necessary to tell bitcoin network the address to which the change will be sent, namely "change address". The change address may or may not be the address used in the original consumption.

3. 1. Your understanding is correct,
2. The bottom one on the right is the change address. If you don't understand, go to the bitcoin teaching of P2P bucks

4. Bitcoin transfer can transfer the balance of multiple addresses out or into multiple addresses at one time
for example, you need to pay Niuniu 5 bitcoins, but there are 1 / 2 / 2 bitcoins in each of your a / B / C addresses, and the balance of each address is not enough to pay for 5 bitcoins
at this time, you can initiate a transfer and transfer 5 bitcoins from a / B / C to Niuniu. Take chestnuts. If you have five bitcoin addresses, you only need to transfer one to Niuniu. You need to tell the miner when transferring money: I have five bitcoins, one of which will be transferred to Niuniu, and the other four will be transferred back to myself (can be the original address or create a new address)
don't forget to say, otherwise the remaining four bitcoins will be used as handling charges for miners. This is the change mechanism of bitcoin.

What should we do if there is a conflict? Who decides the time? I see some information that it's a random choice. If it's a bifurcation, who will decide and merge? Looking forward to expert answers

The motor vehicle inspection station is a private enterprise with a salary of about 2K. It has to work overtime sometimes, but there is no overtime pay. The exhaust gas is too large, and 100% of them have laryngitis

there is no hard work in this instry. To put it simply, the hall is all indoor work. For customer inquiries, the main thing is to have a good temper, because maybe a question needs to be answered many times a day

workshop work is actually outdoor, the environment must be hot in summer and cold in winter, and you must have a driver's license
