PTC
The standard
Defines what is declared, how the declaration is bound to the protected object and how it is verified under the applicable profile.
About Validator
Validator.es is the public reference implementation of the Canal Transparency Protocol (PTC): an open tool for creating and verifying transparency declarations about human–AI involvement, cryptographically bound to the protected digital object.
What each part is
Validator
The implementation
Applies PTC in the browser to create and verify declarations and, where applicable, source files, packages and public disclosure.
El Canal
The conceptual origin
The broader framework from which PTC emerged. It provides context, but knowing it is not required to use Validator or implement the protocol.
ACS-6
The predecessor
An earlier conceptual stage before the current PTC corpus. It is preserved as a historical record, not as a current technical specification.
Publication, versions and authority
The current specifications published under “Protocol and specifications” are the authoritative source for technical conformance. This page and ACS-6 add no normative requirements.
Independent use
PTC is intended to remain independent of El Canal and of any single implementation. Validator can be used, or the protocol implemented, without adopting its original conceptual language.
Authorship and maintenance
Validator.es is developed and maintained by Manuel Barrera Anglada. PTC technical publications identify authorship and versioning through DOI and ORCID.
