Bitcoin executable
Yesterday, I went to the electronic reading room. Not long after I plugged in the USB flash drive, the teacher suddenly asked everyone to unplug the USB flash drive. Some students found that all the files in the USB flash drive could not be opened, and there were two more documents asking for money
so everyone rushed to check, as long as the U disk inserted in the school computer were poisoned, large-scale computer poisoning occurred in the evening
a lot of people's information and graation thesis are in the computer. I really feel that hacker's behavior is disgusting. For the sake of money, regardless of the future of students, teachers' lifelong scientific research achievements...
hope to catch criminals as soon as possible and give them severe punishment by law
this virus will scan windows devices with open 445 file sharing port. As long as the user's device is on the Internet, hackers can implant blackmail software, remote control Trojan horse, virtual currency mining machine and other malicious programs in computers and servers
some security researchers point out that this large-scale network attack seems to be deployed through a worm application, and wannacry can spread among computers. What's more terrible is that unlike most malicious programs, this program can replicate and spread on its own in the network, and most of the current viruses still need to rely on the successful users to spread by cheating them to click the attachment with the attack code
the attack has affected 99 countries and as many as 75000 computers, but because the virus uses anonymous network and bitcoin anonymous transaction to obtain ransom, it is very difficult to track and locate the originator of the virus
1) new transactions broadcast to the whole network
2) each node brings the received transaction information into a block
3) each node tries to find a workload proof with enough difficulty in its own block
4) when a node finds a workload proof, it broadcasts to the whole network
5) if and only if all the transactions contained in the block are valid and have not existed before, other nodes agree with the validity of the block
6) other nodes indicate that they accept the block, and the method of indicating acceptance is to follow the end of the block, create a new block to extend the chain, and regard the random hash value of the accepted block as the random hash value that is faster than the new block
hope to help you.

the essence of money is a credit certificate. You can understand it as an IOU. Bitcoin itself is not money, but because of its concealment and decentralization, it can act as a credit certificate for cross-border settlement, avoid the supervision of various rights, and facilitate money laundering. Therefore, bitcoin becomes money.
