    Dat is a peer-to-peer file synchronization tool that combines an append-only, hash-addressed log with Merkle tree verification, cryptographic access keys, live streaming replication, and swarm networking for sparse, versioned file sharing. It stores file data and metadata in a cryptographically signed, versioned append-only log where each entry is identified by its hash, and uses public-key cryptography to secure archives with separate read and write keys. The tool enables live streaming replication of data between peers as entries are appended, with Merkle tree integrity verification that su

    Dat is a peer-to-peer data synchronization protocol and library rather than a self-hosted cloud storage platform, lacking the centralized server-side file management, S3 compatibility, and user-facing web interface required for a Dropbox-style service.
