The parallel is sharp. In the Middle Ages, shared rules (canon law, merchant codes) created supranational orders like the Church or the Hanseatic League. Today, technology—especially blockchain and smart contracts—enables the encoding of "hard axioms" (e.g., immutability, transparency, automatic execution) into global digital infrastructures. These networks, like Bitcoin or DeFi platforms, operate beyond national borders, challenging traditional state monopolies on currency, contracts, and identity. The potential is decentralized, supranational governance, though legal and social challenges remain.
