Ethical blockchain

Certify your creation, prove your participation

Fingerprints instead of files, certificates instead of tokens to trade. Authorship you can prove, without exposing your work.

Proof of authenticity

A SHA-256 fingerprint of your creation is anchored on a public calendar. It proves the file existed, on that date, in that exact form.

Soulbound membership

Your membership proof is bound to you at your program level. It cannot be transferred, sold or bought — it only attests participation.

Not a speculative asset

No marketplace, no floor price, no resale. An NFT here is an ethical certificate, nothing more.

No training on your work

We do not use your images or documents to train public AI models, and never share them with model providers for training.

Certify this creation

Your file is fingerprinted inside your browser. Only that fingerprint is sent and anchored — the creation itself never leaves your device.

NFT as an ethical certificate, not a speculative asset. We do NOT use your images to train public AI models.

Already have a fingerprint? Verify its certificate without revealing private data.
