Identifiers, claims and verification rules can be controlled and checked in different ways.
LET’S PICTURE IT
A name tag identifies someone, while a membership certificate makes a separate claim about them.

From a public address to a verified signatureStep 1 / 4
An address is public receiving information. It is not the private key that authorizes actions.
An address is public receiving information. It is not the private key that authorizes actions.The local signing system uses secret authorization material. It produces a signature; the private key is not sent along with it.A verifier checks the signed request under the account’s rules. A valid signature does not by itself prove that the action is safe.Balances belong to network state. A wallet is an interface and signing system, not a box containing coins.

Identity has several layers
An address, a name and a credential are not interchangeable. An identifier points to an entity or account; a claim states something about it; a verifier evaluates the evidence under a policy.
A signature binds authorization
A signer can attest to a claim, but verification must establish which signer is trusted for that purpose. A cryptographically valid claim from an unknown issuer may be irrelevant to the desired decision.
Privacy is a design problem
Publishing identifiers and credentials can reveal relationships or personal information. A decentralized mechanism does not automatically make disclosures private or erase them later.
Check expiry and revocation
A claim may no longer be current even if its old signature remains mathematically valid. The verifier needs appropriate context, lifecycle rules and a definition of what it is trying to establish.
QUICK CHECK · NO PRESSURE
Does any valid signature prove any identity claim is trustworthy?
The issuer, purpose, current validity and verification policy all matter.
