A New Standard for
Trusted Human Knowledge
The D-SAFE label is the world's first certification mark for content that is decentralized, integral, common, and knowledge-verified. A public domain gateway for copyright holders, institutions, and authorities.
A certification label, not a platform.
D-SAFE is the verification mark applied to content that has passed the D.I.C. + K standard — the world's first permanent licensing framework built for human knowledge.
It was created to answer a single question: how do you prove that a piece of content is human-authored, safe, legally clear, and permanently accessible?
The answer is a cryptographic audit trail, published on the Arweave permaweb, and the D-SAFE label in the header of every certified work.

Global Sustainability
Rejects environmental harm. Promotes practices that rejuvenate the Earth.
Human Trust
You know what you are reading comes from real experience, not an algorithm.
Safe Learning
Parents and educators can browse with confidence. The internet as a safe classroom.
Reduced Noise
By excluding ads and speculation, we focus purely on what helps you grow.
For copyright holders and authorities.
The D-SAFE Registry serves as the formal contact point for:
- Copyright holders with questions about works published under the D-SAFE label or the D-CODE licence
- Authorities and regulators requiring documentation, provenance records, or audit trails for certified content
- Institutions seeking to adopt the D.I.C. + K standard for their own knowledge platforms
- Researchers and educators who need to verify the certification status of specific works
Every server can die. Every domain can lapse. Every cloud can drop you. This is the one library that survives all of that — because it's already paid for, forever, on Arweave.— Professor Data Pond, Founder
