using cryptography.
To provide public cryptographic proofs that specific content existed at a given time, and enable anyone to trace changes and validate provenance openly and transparently.
The Root Knowledge project is dedicated to making digital information trustworthy, transparent, and accessible. We use cryptographic proofs like Merkle trees anchored to the Bitcoin blockchain to make every fact, change, and timestamp publicly verifiable. Our mission is to empower everyone to trust, verify, and explore knowledge with confidence—protecting the provenance and integrity of information for all.
Access public, timestamped snapshots of knowledge.
Find facts at the sentence or word level instantly.
See every edit and the full history of knowledge.
Claim a unique Root Number for any file, idea, or creation—free and instant, with offline privacy.
We continuously ingest, snapshot, and anchor public sources to establish tamper-proof paper trails and enable transparent verification of changes and origins.
Every asset submitted to our system—whether it’s an idea, artwork, publication, book, source code, or any digital file—receives a free Root Number.
Anyone can instantly pull up a mathematically and legally valid provenance claim for any Root Number at https://root.archi/YOUR-ROOT-#. This provides public, cryptographic proof of existence, authorship, and change history for every asset.
Think of a Root Number like an ISBN—but for any piece of information, not just books. It’s a unique, permanent identifier for ideas, art, publications, code, or any digital creation, making provenance and trust accessible to all.
Root Numbers and their associated provenance claims are designed to be legally valid for copyright, patent, or ownership disputes. You can use a Root Number as evidence of authorship, originality, and existence in legal or commercial settings—helping to protect your rights and prove your claim to any digital asset.

Data Anchors are cryptographic commitments—such as hashes or Merkle roots—securely published to public blockchains. By anchoring data in this way, we create a tamper-proof, timestamped proof that specific content existed at a certain moment in time. This ensures that anyone can independently verify the existence and integrity of the data, even years later.
Data Provenance is the ability to trace the complete history, origin, and changes of digital content. By recording every update and linking it to cryptographic proofs, we make it possible for anyone to audit, verify, and trust the authenticity and evolution of knowledge. This transparency is essential for building trust in digital information.
In a world where misinformation, censorship, and digital manipulation threaten the integrity of knowledge, your support helps us build a future where facts are transparent, tamper-proof, and open to all. Root Knowledge is a public good—anchoring truth, provenance, and trust for everyone.

Root Knowledge is proud to be a partner of the OpenTimestamps project. We use their open standard and calendar servers to anchor all our file and fact stamps, ensuring every proof is independently verifiable and future-proof.
