Interplanetary communication refers to the exchange of data between computational systems located on different celestial bodies, such as Earth and Mars. This involves transmitting signals across vast distances, contending with extreme time delays and signal degradation. Establishing reliable links is a complex engineering challenge for space exploration. Such systems must tolerate long transmission times and intermittent connectivity.
Context
While primarily a space exploration concept, interplanetary communication has tangential relevance to decentralized systems when discussing extreme network resilience or hypothetical future applications. News regarding space missions often highlights breakthroughs or obstacles in achieving these long-distance data transfers. The principles of robust, delay-tolerant networks could inform future ultra-distributed systems. This area represents a distant but interesting application of distributed ledger concepts.
This research introduces Proof-of-Transit Timestamping, a cryptographic primitive for verifiable data trails, ensuring Bitcoin's reliability across high-latency space communication.
