Avalanche is venturing beyond the realm of finance and into the cosmos, with the introduction of a novel network designed to verify telescope data in real-time. SkyMapper's dedicated Avalanche-based network, known as SkyMapper L1, aggregates data from a diverse array of telescopes and sensors globally, converting each observation into a secure digital record. This process creates a 'Proof of Space Observation' (POSO), essentially a method to prove the authenticity of a celestial event, including when it occurred and ensuring the data's integrity.
These verified records can be utilized by scientists, businesses, or government agencies requiring dependable space data. The SETI Institute, renowned for its search for extraterrestrial intelligence, is contributing real-time observational data, marking a significant production-scale integration of institutional science into a blockchain-based verification system.
SkyMapper addresses a growing concern: the exponential increase in data from satellites, drones, and space missions, coupled with the challenge of verifying the data's accuracy. The team proposes that blockchain technology can resolve this issue by creating a permanent, tamper-resistant record of each observation that can be independently verified by anyone. The system operates by validating observations at the moment of capture.
When a network telescope records an event, such as a satellite pass or deep-space signal, the data is immediately cryptographically signed, generating a unique fingerprint tied to the device. The observation is then time-stamped and transmitted through SkyMapper's infrastructure. Instead of storing all data in a central database, SkyMapper distributes it across a decentralized storage network while saving a digital fingerprint of the data on the Avalanche blockchain.
This fingerprint enables anyone to verify the data's authenticity and integrity later. The network utilizes smart contracts to validate incoming data, organize it, and control access. Certain 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, allowing users to confirm when and where it was recorded, verify its integrity, 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 demonstrates how this technology can transform science, providing tamper-proof, verifiable telescope records.'
