The term "BlockChain" originates from #Bitcoin, where it was originally a technical term used to link blocks in the Bitcoin system. However, during the subsequent popularization of the technology, the industry generally misunderstood its essence: It was thought that Blockchain was created to solve the problem of distributed consensus, thereby achieving decentralized trust.
Consequently, "Code is Law" became a popular belief in the blockchain world: As if simply writing rules into code could eliminate the need for trusting people.
But this logic has a flaw:
Ultimately, people are still making the decisions. Even BFT (Byzantine Fault Tolerance) mechanisms only change "trusting one person" into "trusting a group of people."
The greatness of Bitcoin lies in the fact that: It has never trusted people, nor has it trusted code. The only thing it trusts is: irreversible time.
Rather than saying that Bitcoin's blockchain is meant to solve the consensus problem, it's more accurate to say: It is meant to establish a complete evolutionary path in an open and uncontrollable environment.
Specifically:
Bitcoin does not rely on BFT protocols or synchronous communication from traditional distributed systems. Instead, it uses two technical approaches:
Under this structure, even if a local inconsistency appears, as long as time continues to advance, the system will continuously approach completeness as a whole.
Most blockchain projects attempt to be "consensus machines": They strive for all nodes to be in perfect agreement at every moment, believing this to be the source of trust.
Bitcoin's design is more profound:
In any sufficiently complex formal system, consistency and completeness cannot both be achieved.
This is the basic proposition of Gödel's incompleteness theorems.
Bitcoin does not seek to achieve both within the system; instead, it:
This is Bitcoin's true originality.
The real innovation is not in the word "blockchain," but in how Bitcoin, through the irreversibility of time, extracts trust from "people" and "code" and entrusts it to a natural evolutionary process that requires no single subject. This is why Bitcoin is an unprecedented organic computer—it trusts not consensus, not the crowd, not algorithms, but irreversible time itself.
