В отличие от существующих реализаций Root of Trust, OpenTitan развивается в соответствии с концепцией «безопасность через прозрачность», подразумевающей доступность кода и схем, а также полностью открытый процесс разработки, не привязанный к конкретным поставщикам и производителям чипов. В основу решений, применяемых в OpenTitan, заложены технологии уже используемые в криптографических USB-токенах Google Titan и TPM-чипах для обеспечения верифицированной загрузки, устанавливаемых на li-server mabapi le meralo ea motheo ea Google, hammoho le ho Chromebooks le lisebelisoa tsa Pixel.
OpenTitan ke sethala sa Root of Trust (ROT) se ka sebelisoang moo botšepehi ba lisebelisoa le lisebelisoa tsa software li hloka ho netefatsoa, ho netefatsa hore likarolo tsa bohlokoa tsa tsamaiso ha lia senyeha 'me li thehiloe holim'a khoutu ea moetsi e netefalitsoeng le e lumelletsoeng. .
