Introduction

In OpenCerts 2.0 we are further expanding the reach of the OpenCerts ecosystem by allowing the Domain Name System (DNS) to be used as an identity registry — in addition to our current SkillsFuture Singapore Accreditation Registry. A one-liner introduction to the DNS system can be summarised as: “Phonebook for the Internet”. It is indispensible and used by almost all services involving the Internet.
