Crypto started with ETH's blockchain, abandoning Satoshi Nakamoto's core intention for BTC: decentralization, where private keys 100% own account asset sovereignty in a decentralized manner. On the other hand, blockchain modeling began with: decentralization (removing direct human operation), trusting the absolute centrality of consensus code, and establishing a new center driven by consensus code rules. The permissions of consensus code can operate any individual private key account system. The two have a fundamental difference in starting points.
