The Intergalactic Timebank is designed around mutual credit, governance, and auditability rather than high-frequency financial settlement. This makes it a strong candidate for architectures that avoid per-transaction gas fees by separating everyday activity from final settlement. Any interchain partner must support this layered approach rather than forcing all activity on-chain. The core principle is that most Voz activity is informational, social, and reputational. These actions should be cheap, fast, and local. Only governance decisions, batch finalisation, and dispute outcomes need strong finality. A suitable interchain framework must therefore support asynchronous anchoring, governance signatures, and verifiable proofs without charging users per action. Another principle is non-market integrity. The system must prevent Voz or certificates from becoming speculative assets. Gas-free or gas-minimal systems must not quietly reintroduce economic pressure through hidden fees, rent extraction, or privileged validators. The economic model of the chain itself matters as much as the technology. Finally, the architecture must align with constitutional governance. If rules change, fees appear, or validators gain unilateral power, the system fails its social contract. Minimal gas is not just a technical requirement but a governance one.
