Briefing

This paper addresses the profound challenge of extending Bitcoin’s operability across the vast, high-latency distances inherent in interplanetary communication. It proposes Proof-of-Transit Timestamping (PoTT), a novel cryptographic primitive designed to create tamper-evident audit trails for Bitcoin data over intermittently connected links. This foundational breakthrough enables Bitcoin to function reliably as an interplanetary monetary standard, preserving its core consensus while fostering secure off-chain settlement and expanding its economic reach into space.

Context

Traditional blockchain designs, including Bitcoin’s, operate under the implicit assumption of relatively low-latency and continuous network connectivity for efficient transaction propagation and consensus synchronization. This established theoretical model encounters significant limitations in extreme environments like interplanetary space, where immense distances, intermittent communication links, and substantial signal delays render conventional block propagation and network synchronization impractical. This prevailing theoretical limitation restricts Bitcoin’s potential as a universal monetary base beyond Earth’s immediate vicinity.

Analysis

Proof-of-Transit Timestamping (PoTT) introduces a new transport-level receipt primitive. It functions by cryptographically chaining hop-timed custody attestations to Bitcoin payload hashes, thereby generating tamper-evident propagation histories. This mechanism fundamentally differs from previous approaches by integrating network-layer transit proofs directly into the data’s verifiable history, specifically designed for Delay/Disruption-Tolerant Networking (DTN) and leveraging optical low-Earth-orbit (LEO) mesh constellations for robust data relay. PoTT provides verifiable accountability for data transit, enabling reliable off-chain mechanisms, such as long-horizon Lightning channels and federated sidechains, to operate securely despite extreme communication delays.

Outlook

Future research will likely focus on optimizing PoTT’s integration with diverse interplanetary communication architectures and refining its security model under various adversarial space environments. This theory holds the potential to unlock real-world applications within 3-5 years, establishing robust financial infrastructure for lunar bases, Mars colonies, and deep-space missions. This development fosters a truly solar-system-wide digital economy by extending Bitcoin’s verifiable utility across cosmic distances.
