Bitcoin knowledge: Can the Bitcoin algorithm (protocol) be modified? At present, the Bitcoin algorithm is becoming more and more diverse, and its algorithm can also be modified. It has been changed from the original single mode POW to POW plus POS system.

Therefore, it is completely impossible to say that the Bitcoin algorithm cannot be modified. When it is modified, it is not as difficult as imagined. Of course, the editor will tell you about its specific modifications.

Last Saturday, Bitcoin.org and Bitcointalk.org administrator Cobra published an open letter on Twitter. The main content of the open letter is that the Core development team believes that the Bitcoin computing power is concentrated in the hands of one person and his company BITMAIN. Core believes that this is a potential threat to the Bitcoin network. In order to solve this situation, Core decided to change the original POW computing power mechanism and use a hybrid POW system + POS to build ASIC.

It can be clearly felt from the open letter that Cobra has a clear prejudice against BTIMAIN and its founder, and this prejudice has even risen to the country. This is not the first time Cobra has discredited Bitmain and China.

He believes that BITMAIN has an absolute lead in computing power and will continue to maintain this phenomenon in the future, and the security of the Bitcoin network will be affected. Regarding the concentration of computing power, Cobra does not have any evidence to support this statement. It is just an artificial speculation based on an analyst's estimate report, and the credibility is questionable.

Moreover, even if the computing power is concentrated, it is also the choice of the market. Satoshi Nakamoto wrote the rules in the white paper. Anyone can get Bitcoin through mining, and everyone is a node. This rule still applies today. Anyone can mine, but it does not mean that everyone is willing to mine, or that everyone's computing power will be equal. This point only exists in ideals and is difficult to achieve in reality.

In short, the Bitcoin algorithm can be modified, but when modifying it, investors should also pay attention and not mess around, but follow the steps step by step.
