Trust Boundary
Each verification mechanism establishes a specific property. Applications should draw only the conclusions supported by the verification that succeeded.
A valid protocol result does not automatically establish the meaning, trustworthiness, authority, or real-world status of the underlying content.
Verification Claims
| Mechanism | Establishes |
|---|---|
| Block verification | The supplied Block produces the recorded deterministic identities under ALX rules. |
| Graph verification | The evaluated declared relationships satisfy ALX structural graph rules. |
| Signature verification | The supplied signature is valid for the specified payload, signer, domain, and verification context. |
| Merkle verification | The supplied Block identity is included in the set represented by the specified Merkle root hash. |
| Blockchain commitment verification | The specified Merkle root is recorded in the selected contract and chain context. |
The listed verification properties can be verified independently. Success at one layer does not imply success at another.
Trust Boundary
Successful verification establishes only the property evaluated by that mechanism.
Verification does not establish:
- Factual accuracy
- Semantic truth
- Authorship
- Ownership
- Authorization
- Quality
- Policy compliance
- Legal validity
- Safety
- Application intent
Applications and external systems determine how verified protocol properties affect trust, permissions, policy, and downstream decisions.
Applying Verification Results
Present verification results according to the property actually established.
A valid Block identity establishes deterministic correspondence to protocol data. A valid signature establishes cryptographic evidence associated with a specified signer and payload. A valid Merkle proof establishes inclusion relative to a specified root. A verified blockchain commitment establishes that the root was recorded in the selected onchain context.
Any stronger interpretation requires additional application-defined evidence, policy, or trust assumptions.
When to Apply
Review the verification claim before presenting user messages, audit evidence, access decisions, or security controls.
