Meme is a kind of mental gene, possessing a 'double helix structure'; it replicates on one side while mutating on the other. In other words, it stabilizes and restores its formal structure through inheritance on one side, while recursively breaking out of its original structural form through self-reference, evolving dynamically into the next emergent structural form. This idea belongs to Turing's ordinal logic structure—on one side, the formalized determinable computability of the Turing machine, and on the other, the intuitive probabilistic self-referential re-axiomatization of the Oracle machine. At the same time, it also aligns with Satoshi Nakamoto's concept: the generation and verification of Bitcoin's block/tx are based on the formalized Turing machine theory, while the selection of the longest chain corresponds to the intuitive Oracle machine theory, which incorporates self-referential problems and evolves the self-referential subject.
