These certificates allow you to validate signatures that are signed with certificates that chain up to those trusted certificates. In other words, you can validate those signatures without the extra steps of trusting each signer's certificate or manually configuring another trust anchor. These certificates are carefully selected and generally belong to major organizations such as countries or government agencies.
