FMZ What we talk about when we talk about blockchain security? Decentralized, untamed, these nouns come out of everyone's mouth, as if the security of the blockchain is a self-evident truth. The blockchain seems to be regarded as a good medicine from the moment of birth. However, the reality is cruel. Whether it is Bitcoin or Ethereum, hackers are everywhere, and news of stolen digital currency is frequently reported. The security of the blockchain system does not depend solely on the blockchain algorithm itself, from code implementation to contract logic to supporting facilities. When the blockchain technology emerges from the white paper and becomes a technology in reality, there are far more problems. According to the barrel theory, how much water a barrel can hold does not depend on the longest piece of wood, but on the shortest piece of wood. password! password!

www.fmz.com I believe that the white paper published by Nakamoto in 2009 is far more than just for profit. The essence is to change the entire social system, break the current centralized system, and eliminate corruption, power mismatch in this relationship to power. I call for the establishment of a new culture based on decentralized thinking, thus realizing the subversion and innovation of relationship to power. The following opinion piece on building a decentralist culture was written by Max Borders, director of  Social Evolution  and author of  The Social Singularity .

After watching the movie, I feel that nice frauds in ten gambles. Honest people like me cannot go to casinos Is this true in the casino? Is it to rely on various high-tech means to cheat and earn money from gamblers? Actually it’s not, the real situation is just the opposite.

[My great achievements shall be cast on bronze, carved on marble and engraved on wooden boards forever. When these deeds are circulated in the world, the age of happiness also come. Cervantes Don Quixote] On the occasion of the tenth anniversary of the birth of this bitcoin, I sent this sentence to Satoshi Nakamoto, paying tribute to this great era. 01 The clock goes back to 2008, and the world is struggling with the worst global economic recession in half a century.

www.fmz.com After attending a blockchain meeting, what I feel most deeply is "privacy". In the era of big data, our information is undoubtedly invaluable, but we can't profit from it, and its value is almost taken away by the large Internet platform. When others use our information, they do not need to ask for our permission, and we don’t even notice. The Internet world we are currently in is full of loopholes everywhere. Such huge amounts of information are stored in a centralized Internet platform, and the platform is unwilling to pay a high price for protecting data. Hackers, dark networks, information leaks...

We are not willing to let everyone know all of our deeds, because this will undermine our image in the eyes of others and undermine the characters we shape. Even more frightening is that in an era when AI predictions are so developed, once all our historical data
