The value of fiat currency comes from peer-to-peer trust. But it’s not purely peer-to-peer—issuance and circulation introduce unverified logic. Unverified logic is the loophole that allows modern corporations and institutions to collude and infringe on others' rights. Similarly, BFT PoS signatures also have unverified logic vulnerabilities. Only by fully returning the verification of logic to peer-to-peer can we eliminate 'unverified logic vulnerabilities.' Peer-to-peer is the immutable law of the physical world.
