> The Authenticated Transfer (AT) repository and synchronization protocol addresses the challenges of building decentralized applications that require consistent data replication across distributed multi-party infrastructure. Traditional web platforms maintain user data at a single network location, creating vendor lock-in and limiting user agency over their digital identity and published content.
> In the AT model, user data is stored in cryptographically signed repositories that can be hosted, synchronized, and distributed by any compatible server while preserving data authenticity and user ownership. Each repository consists of a set of CBOR-encoded objects called records, organized lexicographically by type. The cryptographic structure allows repository contents to be re- distributed and cached by any network participant without requiring trust in intermediary hosts.
