Blockchain timestamps are milliseconds

1. digital currency will not be stolen in general. If you use a regular wallet and invest in a regular digital currency, there will be no problem!

2. In order to prevent the double spending problem, the system will automatically time stamp the transaction information of each block and mark it with time brand. How much money you spend at this time is spent. It has been recorded and can't be used to buy other things
how to record it? In fact, the time stamp and other transaction information on the block are calculated to obtain an encrypted value, which is called "hash value". Each new block contains the hash value of the previous block, thus forming a blockchain
so we say: bitcoin system is actually a layer by layer nested, never-ending, very powerful timestamp system, which uses timestamps to ensure that each block is linked into a "chain" (that is, block chain) in chronological order
from this point of view, time stamp literally means to time stamp a block. Its practical function is to provide an important parameter for later hash value calculation, which is an essential and very important information in the process of calculation and verification
finally, we summarize the content of this section. This section mainly introces two terms: utxo and timestamp. These two concepts are important means to solve the "double flower problem", which can ensure that bitcoin can not be used many times without a third party organization.

3. In short, timestamps prove what happened at what time on the blockchain, and no one can tamper with it. Blockchain ensures that each block is connected in sequence by timestamp. Time stamp makes every data on the
blockchain have time mark

4. A timestamp, usually a sequence of characters, uniquely identifies the time of a moment. Digital time stamp technology is a variant of digital signature technology
time stamp refers to the total number of seconds from 00:00:00 GMT on January 1, 1970 (Beijing time: 08:00:00 GMT on January 1, 1970) to now
to put it simply, a time stamp in a blockchain means that whatever happens at a certain time will be recorded on the blockchain. For example, the blockchain content publishing platform decent, when someone publishes some information on it, the information will be recorded from the moment of release, which can't be changed. The time of occurrence is fixed and can't be changed.

5. It's junk software. There are harsh conditions for withdrawal after the withdrawal amount

6. It's possible for the whole people to raise golden mice for cash withdrawal, but if they don't invite friends, they need to play for several months if they want to withdraw up to 60 yuan. If you want to withdraw cash quickly, you can't do without inviting friends!

1. Points purchase
points can directly purchase talent cards, and 100 points can purchase 60 talent cards. But it is not easy to get points, because only victory can get points, and a victory can only get 5 points, so 100 points need to win 20 games<

2. When buying gems, you can buy points directly, but generally, gems are reserved for players. For local tyrant players, you can buy them at will, but it is more suitable for general players to keep them

voucher use guide

in the early stage, it is recommended to buy a physical bag, but I don't know if it will come out in the early stage. Now it has been a period of internal test before it comes out

I feel that I can draw some special players' bags, such as the match players' bags. Once I draw the best players, you will soar to the sky

of course, if there is a gold coin bag in the early stage, it should be used to buy gold coin bags first, and all of them can be used to buy gold coin bags. When the physical strength can't keep up in the later stage, it can buy physical strength and brush the plot. The main reason is that there is a shortage of gold coins in the early stage. If there are gold coins, you can buy the best players at a low price
