Its different mostly in the methodology and requirements.

GNU Taller is developed without input by governments or existing legal frameworks. Christian Grothoff has done pioneering work for years. Its ideology driven, not government driven. We're different. We are trying to ensure compliance with very complex eIDAS regulations, GDPR, KYC, and AML. In partnership with governments and Brussels are trying to discover what is possible and desired.

Could you be a little more specific how these aspects manifest themselves, please?
