About Truestamp
Our Mission
In an era of deepfakes, AI-generated content, and digital manipulation, proving when data existed and that it hasn't been altered is more important than ever. Truestamp exists to give individuals and organizations the tools to create independently verifiable proof of their digital data, without trusting any single party, including us.
We believe that trust should be built on mathematics and transparency, not promises. Every timestamp we create can be independently verified using open cryptographic standards and public blockchain records.
What Makes Us Different
Data Minimization
We store the cryptographic hash you submit, plus any claims or metadata you choose to include. Hash your data locally and send only the hash, and your content never reaches us at all. Anything you do choose to send, you can redact later.
Data Redaction
Permanently delete submitted data while preserving cryptographic proof of existence. Uniquely supporting right-to-be-forgotten without breaking the chain.
Multi-Blockchain Commitment
Every block is committed to both Stellar and Bitcoin, providing redundant public proof across independent blockchain networks.
Independent Verification
Anyone can verify timestamps without our systems. Cryptographic proofs are self-contained and can be checked using open source tools we provide.
Our Approach
- Transparency: Open verification, public blockchain records, documented cryptographic standards
- Privacy-first: Hash-based verification, user-controlled redaction, minimal data collection
- Verifiable: Every claim is independently provable using SHA-256 hashing, Ed25519 signatures, and Merkle tree proofs
- Honest: We prove submission timing and data integrity, not creation time, and we're upfront about the distinction
