Check internal checksum consistency.

Paste a downloaded JSON artifact and we recompute its checksum in your browser, then compare it with the value carried in the file. Nothing is uploaded. A match shows checksum consistency only. It does not prove Teranode issuance, human attestation, authenticity, or filing.

Anyone can run this comparison on any supported JSON artifact, with no account. Because the checksum travels with the content, this is not an identity, issuance, attestation, authenticity, or filing check.
