Blockchain technology is expanding from finance into scientific data verification, as SkyMapper builds a dedicated Avalanche-based network to validate telescope observation data in real time. The system records and preserves data with checks for tampering through a mechanism called Proof of Space Observation. Observation data are cryptographically signed at the moment of capture, stored across a distributed network and fingerprinted on the Avalanche blockchain for later verification. Smart contracts also manage access controls, keeping sensitive government or defence data private while sharing research data.
