Guildmark

Brands, agencies and syndication partners exchange creative that may change between internal approval and publication. The supplied research confirms mature public transparency-log and identity-certificate infrastructure and found no reviewed marketing-specific registry. That makes the mechanism technically plausible, but it does not prove buyer coordination, category absence or a network effect. No product-specific marketing interfaces were verified. Numeric infrastructure prices are omitted because they are observed market references, not fixed product pricing.

A cryptographic signature establishes that a key signed a specific digest under stated conditions. It does not prove the signer had business authority, the creative satisfied policy, rights were cleared, disclosures were legally sufficient, the artifact was actually published or the destination rendered the same bytes. Policy specifications change, approvals expire, keys are compromised and creative can be transformed by a channel. A public log can leak campaign timing, identity or confidential metadata unless the record is minimized.

Creative asset, canonical representation, digest, policy version, validation result, reviewer finding, signer identity, business authority, approval, signature, transparency receipt, verification, revocation, corrected asset, destination submission, acknowledgment, readback, publication and compliance outcome remain separate. Guildmark should prove provenance and approval history while keeping brand, legal and channel authority external.
