What to know : Avalanche is expanding beyond finance into space data, with SkyMapper launching a network that turns telescope observations into verifiable records, including live input from the SETI Institute. The system works by signing observations at capture, storing them across decentralized infrastructure, and anchoring a digital fingerprint onchain so anyone can verify the data’s authenticity, timing and origin. SkyMapper’s pitch centers on a growing problem: the explosion of data from satellites, drones and space missions, and the difficulty of verifying that data hasn’t been altered or misattributed.
Avalanche is moving beyond finance and into outer space, with a new network designed to verify telescope data in real time.
SkyMapper has introduced a dedicated Avalanche-based network that cryptographically records observations from telescopes around the world, turning each data point into a secure, verifiable digital record.
The new network, SkyMapper L1, collects data from a wide range of telescopes and sensors around the world and turns each observation into a secure digital record. The company calls this a “Proof of Space Observation” (POSO) — essentially a way to prove that a specific event in the sky was actually seen, when it happened, and that the data hasn’t been altered. These verified records can then be used by scientists, businesses or government agencies that need reliable space data.
The SETI Institute, known for its search for extraterrestrial intelligence, is contributing live observational data, marking one of the first production-scale integrations of institutional science into a blockchain-based verification system.
SkyMapper’s pitch centers on a growing problem: the explosion of data from satellites, drones and space missions, and the difficulty of verifying that data hasn’t been altered or misattributed. The team argues that blockchain can help solve this by creating a permanent, tamper-resistant record of each observation that anyone can independently verify.
The system works by validating observations at the moment they are captured. When a telescope in the network records an event — such as a satellite pass or deep-space signal — the data is immediately cryptographically signed, effectively creating a unique fingerprint tied to that device. The observation is then time-stamped and transmitted through SkyMapper’s infrastructure.
Instead of keeping all the data in one central database, SkyMapper spreads it across a decentralized storage network. At the same time, it saves a kind of digital fingerprint of that data on the Avalanche blockchain. This fingerprint means anyone can later check it to confirm the data is real and hasn’t been changed.
The network uses smart contracts to check incoming data, organize it, and control who can access it. Some information — like sensitive government or defense data — can be kept private, while other data, such as scientific research, can be shared openly.
The result is a system where each observation can be independently verified: users can check when and where it was recorded, confirm it hasn’t been tampered with, and trace it back to its 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.”
