Misunderstandings of blockchain: The term Blockchain comes from Bitcoin. But everyone misunderstands the role of Blockchain, thinking that it is decentralized and trusted by resolving the contradiction of distributed consistency. So there was once a widely recognized blockchain technology in the industry as' Code is Law '. Who should the code itself trust? Not yet a BFT proxy code person, trusting codes only changes the logic of trusting people from direct to indirect, from one person to multiple people. Bitcoin never trusts people or code, but irreversible time. The true blockchain technology of Bitcoin solves not the problem of consistency contradiction, but the problem of completeness. So the phenomenon we see is that the Bitcoin chain allows for rollback without 100% consistency. However, Bitcoin Blockchain technology has established an irreversible time chain through a dissipative structure framework and a super poor iterative ordinal logic system technology, allowing the system to achieve dynamic completeness, thereby making the system distrust people and code, only trusting irreversible time. Consistency and completeness cannot be compatible in the same system, which is the core idea of G ö del's incompleteness theorem.
