Test Vectors

To ensure interoperability between different implementations of the ATL Protocol, we provide a suite of test vectors.

1. JSON Canonicalization (JCS)

Test cases for RFC 8785 compliance, including:

• Key ordering (UTF-16 code point order)
• Number formatting (no trailing zeros)
• Unicode handling (no escaping of non-control characters)

2. Merkle Tree Operations

Test cases for RFC 6962 consistent Merkle tree operations:

• Tree construction from 1 to 1024 leaves.
• Inclusion proof generation and verification.
• Consistency proof verification.

3. Sample Receipts

Full Evidence Receipts (.atl) for end-to-end verification testing:

• Minimal: No metadata, single leaf.
• With Metadata: Rich JSON metadata using JCS.
• With Anchors: Including both RFC 3161 and Bitcoin OTS proof data.
