Blockchain enabled timestamps for media files. Proof of ownership, proof of integrity, and proof of existence on mobile devices. BlockNotary Timestamp notarizes any media file, generating publicly verifiable receipt of its origin, date, authenticity, and integrity, without exposing its contents. Its uses include digital attribution, proof of existence, prior knowledge, integrity, and authenticity. Timestamp creates 100% distributed proofs using OTS (OpenTimestamps), IPFS (InterPlanetary File System) and public Bitcoin or Ethereum blockchains. Generated receipts are independently verifiable and machine-readable. Upload a media file to the app and securely store it in a distributed file system that is protected by the blockchain.

AlphaEarth Foundations is a new AI model from DeepMind that acts like a “virtual satellite” by integrating massive, heterogeneous Earth observation data, optical and radar imagery, 3D laser mapping, climate simulations, and more, into a unified, highly compact embedding for land and coastal areas, enabling consistent, on-demand planetary-scale mapping with far less storage overhead than prior systems. It fuses disparate streams to solve data overload and inconsistency, producing summaries that are 16 times smaller than comparable methods while delivering better accuracy (about 24% lower error in tested tasks) even where labeled data is sparse. Annual embedding collections are published as the satellite embedding dataset in Google Earth Engine and are already being applied by institutions to classify unmapped ecosystems, monitor agricultural and environmental change.
