Public Commitments and Private Information
Technical guide · Updated 17 September 2026 · Digital identity on XRPL.
A fingerprint has a limited meaning
A hash can help detect changes to the bytes that were hashed. It does not establish authorship, permission, clinical accuracy or legal ownership. A commitment’s meaning depends on its construction and the context in which it is checked.
Public does not mean harmless
Accounts, submitted metadata and transaction relationships can be visible on a ledger. A hash of a guessable input may still leak information. Encrypted data can also expose timing, size and relationships even when the plaintext is unavailable.
What the evaluation publishes
The connected anchoring step submits the registry metadata described by the tool, not the holder secret or plaintext identity documents. Inspect the transaction contents directly rather than inferring privacy from the appearance of an opaque string.
Evaluate the boundary
- Use test samples, not personal or genomic data
- Separate a signature check from a content-integrity check
- Inspect metadata and access-link exposure
- Record which network and snapshot each result refers to
Genomics requires its own design
A future genomic application would need a validated scientific claim, an appropriate issuer, careful commitments and a reviewed disclosure model. The current test identity proof should not be presented as proof of DNA ownership or a clinical result.
