I'm referring to the EU eIDAS regulations:
https://eur-lex.europa.eu/legal-content/EN/TXT/?uri=uriserv:OJ.L_.2014.257.01.0073.01.ENGArticle 25
2) A qualified electronic signature shall have the equivalent legal effect of a handwritten signature.
Article 3
(12) qualified electronic signature means an advanced electronic signature that is created by a qualified electronic
signature creation device, and which is based on a qualified certificate for electronic signatures;
(15) qualified certificate for electronic signature means a certificate for electronic signatures, that is issued by a qualified trust service provider and meets the requirements laid down in Annex I;
Article 22
Trusted lists
1. Each Member State shall establish, maintain and publish trusted lists, including information related to the qualified trust service providers for which it is responsible, together with information related to the qualified trust services provided by them.
All in all:
1. Only a qualified electronic signature has the same legal effect in EU as a handwritten signature.
2. Qualified electronic signature requires a qualified certificate issued by a qualified trust service provider which has to be put on the list by the EU Member State.
None of this is the case with Obyte which means that it's signatures are not legally binding.
