Crate atlas_transparency_log 

Atlas Transparency Log

A transparency log implementation with Merkle tree support for C2PA manifests.

Overview

This library provides:

• Merkle tree implementation with inclusion and consistency proofs
• Content format detection (JSON, CBOR, Binary)
• Cryptographic signing and verification
• Manifest storage and retrieval

Example

use atlas_transparency_log::merkle_tree::{MerkleTree, LogLeaf};
use chrono::Utc;

let mut tree = MerkleTree::new();
let leaf = LogLeaf::new(
    "content_hash".to_string(),
    "manifest_id".to_string(),
    1,
    Utc::now(),
);
tree.add_leaf(leaf);

// Generate inclusion proof
let proof = tree.generate_inclusion_proof("manifest_id").unwrap();
assert!(tree.verify_inclusion_proof(&proof));
