Data Mining (a) Do you really understand what is data mining and the data itself?

The idea of self-taught machine learning is really because of my interest in data mining, because in my heart I have always believed in the logic that there is a certain pattern behind everything, and that different situations only correspond to certain conditions. So to find such a pattern is the most convenient and quickest way to solve a class of problems, as a lazy person like me, of course, I would like to use the most efficient way to solve the problem. Next, I intend to write a series of

Introduction to Virtual currency development

involved in processing the block needs to pay a lot of time and computational power, which is very similar to mining, so Nakamoto named the deal processor "miner" and called the transaction processing activity the mining. These newly generated bitcoins can reward transaction handlers in the system, and their computing work guarantees the operation of the Bitcoin trading network. By mining, the bitcoin system injects money into the economy.In addition

" 0x776689315d837b5f0d9220dc7c0e7315ef45907e188684a6609fde8fcd97dd57 " There's one more thing to be aware of, and it's easy to confuse, and that's why these numbers are worth 0 more. This is because the values are represented by Wei, so you do not have to deal with floating-point numbers that may cause problems on different systems. This will be related to gas (a measure roughly equivalent to the calculation step). Each transaction needs to include a gas limit and a fee that is willing to pay
