Avalanche is extending its reach beyond the financial sector and into the cosmos, with the introduction of a novel network designed to authenticate telescope data in real-time. SkyMapper's innovative Avalanche-based network, known as SkyMapper L1, aggregates data from a diverse array of telescopes and sensors worldwide, converting each observation into a secure digital record. This process, dubbed 'Proof of Space Observation' (POSO), provides irrefutable evidence that a specific celestial event was observed, including the time of occurrence and the assurance that the data remains unaltered.
These verified records can be utilized by scientists, businesses, and government agencies requiring reliable space data. The SETI Institute, renowned for its pursuit of extraterrestrial intelligence, is contributing real-time observational data, marking a significant production-scale integration of institutional science into a blockchain-based verification system. SkyMapper's solution addresses the escalating issue of data explosion from satellites, drones, and space missions, coupled with the challenge of verifying the authenticity and integrity of this data.
By leveraging blockchain technology, SkyMapper creates a permanent and tamper-resistant record of each observation, enabling independent verification 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 device-tied fingerprint. 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 allows for later verification of the data's authenticity and integrity.
The network utilizes smart contracts to validate incoming data, organize it, and regulate access. Certain information, such as sensitive government or defense data, can be kept private, while other data, like scientific research, can be shared openly. The outcome is a system where each observation can be independently verified, enabling users to confirm the recording time and location, verify the absence of tampering, and trace the data back to its source.
'We are developing blockchain infrastructure for real-world impact,' stated Emin Gün Sirer, founder and CEO of Ava Labs. 'SkyMapper's work in anchoring observatory data on Avalanche demonstrates how this technology can transform science, providing tamper-proof and verifiable telescope records.'
