Ziurta (zee-OOR-tah) is the Basque verb ziurtatu in its bare form: to verify, to vouch for, to certify. It survived as a language isolate by being maintained, generation after generation, by people who thought it was worth the trouble.
Credentials work the same way. A license, a certification, a network agreement: none of them hold on their own. They hold because someone keeps them current. Ziurta is the system that keeps them current.
