Avalanche is steering blockchain beyond finance and into the cosmos with a new network built to verify telescope data in real time. SkyMapper has launched SkyMapper L1, an Avalanche-based network that cryptographically records observations from observatories and sensors around the world, turning each sighting into a secure, verifiable digital record.
SkyMapper calls the method a “Proof of Space Observation” (POSO). POSO provides an auditable way to prove that a particular event in the sky was seen, when it was seen, and that the data hasn’t been altered. That kind of provenance is increasingly important as satellites, drones and space missions generate massive volumes of imagery and telemetry that must be authenticated before scientists, companies or governments can rely on them.
The network validates observations at capture: when a telescope or sensor records an event — a satellite flyby, an asteroid detection, or a deep-space signal — the device cryptographically signs the data, creating a unique fingerprint tied to that instrument. The observation is timestamped and transmitted into SkyMapper’s infrastructure. Rather than concentrating all raw files in a single database, SkyMapper distributes the data across decentralized storage while anchoring a compact digital fingerprint of the record on the Avalanche blockchain. Anyone can later check that fingerprint against the stored data to confirm authenticity and detect tampering.
Smart contracts handle incoming data, catalogue observations and enforce access controls. That lets SkyMapper make scientific records openly available where appropriate, while keeping sensitive government or defense-related observations private. In other words, the system combines public verifiability with configurable privacy.
One of the most notable integrations so far is live observational input from the SETI Institute — a production-scale example of institutional science feeding verified data into a blockchain-based system. SkyMapper positions this as a practical solution to the growing problem of data provenance in space operations: trustworthy, timestamped records that can be independently verified and traced to their source.
“We’re building blockchain infrastructure for real-world impact,” said Emin Gün Sirer, founder and CEO of Ava Labs. “SkyMapper’s work anchoring observatory data on Avalanche shows how this technology can transform science, providing tamper-proof, verifiable telescope records.”
By applying Avalanche’s immutability and smart-contract capabilities to astronomical data, SkyMapper aims to make space-derived information more reliable for researchers, commercial operators and governments — effectively extending blockchain’s use cases from DeFi to the final frontier.
