In other words, when we aim to design cryptocurrency technology better than Satoshi Nakamoto's, we shouldn't just focus on improving blockchain technology like ETH does. Instead, we should reconsider replacing the blockchain structure with a self-referential structure defined by ordinal numbers that is easier to scale. This is because the self-referential closed-loop logic of the blockchain structure, which lies in the block hash, is inherently limited by the blockchain's technical structure and will inevitably remain as fair as BTC's hash collision self-referential structure.
