Use Cases

Your seal.
Everywhere it matters.

One identity, verified once, usable across every context where being human — and being trustworthy — makes a difference.

The following are not edge cases. They are the situations that millions of people face every day — situations where the question "can I trust this person?" matters enormously, and where today there is no clean answer. Jitsuin changes that.

Content Creators — your work, linked to you, everywhere

Platforms come and go. Algorithms change. Accounts get suspended. But your Jitsuin belongs to you, not to any platform — and every piece of content you seal is permanently, cryptographically linked to your identity, regardless of where it lives.

When it is time to negotiate a contract, a brand deal, or a licensing agreement, your chain of trust tells the full story: this is how long I have been creating, this is my verified body of work, this is the authority I have built. No platform can rewrite that record. No AI can fake it.

Seal videos, articles, audio, and images — each one tied to your verified identity with a unique SHA-256 hash
Use your Jitsuin across all platforms simultaneously — YouTube, Instagram, Substack, your own site — and consolidate everything into one verifiable body of work
When you negotiate contracts, share your chain of trust to demonstrate your authority, reach, and creative history — in a form that cannot be inflated or fabricated
Prove your work is human-made in a world where audiences and brands are actively looking for that assurance

Students Education Academic Work Career

Students — prove you know what you know

In a world where AI can write any essay, complete any assignment, and generate any analysis, the ability to prove that your thinking is genuinely yours is becoming one of the most valuable professional assets a person can have.

Jitsuin lets students build a verified, timestamped record of their intellectual work — not just the final grades, but the notes, the drafts, the process. Uploaded via CCEF3, this creates a complete chain of evidence for how your CV came to look the way it does. Advanced analytics provide deep insight that a CV simply cannot capture — showing future employers not just what you achieved, but how you think.

Seal your notes, essays, and research as you produce them — creating an incontrovertible timestamp of original human thinking
Upload your work via CCEF3 to build a complete chain of intellectual provenance — the full story of your academic development
Share advanced analytics with future employers that reveal depth of thinking, consistency of effort, and genuine expertise — things a CV cannot show
Enter the job market with a verified, tamper-proof record of genuine human intellectual work, distinguishing yourself clearly from those who outsourced their thinking to AI

Legal Contracts Agreements Smart Contracts Freelance

Contracts & Agreements — signed by a human, enforced by mathematics

A contract is only as strong as the identity behind the signature. With Jitsuin, your signature — whether ink on paper with a physical seal, or a digital hash on a document — is permanently tied to a verified human identity that cannot be repudiated.

Digital contracts sealed with a Jitsuin can automatically execute terms: payments release when deliverables are confirmed, access is granted when conditions are met, obligations trigger without manual follow-up. The signature you have generated becomes the key that unlocks everything downstream.

Add any contract or agreement to your chain — creating a permanent, timestamped record of every commitment you have made and honoured
Use your physical Jitsuin stamp on paper contracts, generating a digital ID for the same document simultaneously — physical and digital in one act
Enable smart contract execution — payments, deliverables, and access rights that trigger automatically based on your verified digital signature
Both parties can verify the other's identity level before signing — choose the level of trust the agreement requires

Licensing Distribution Franchising Partnerships

Licensing — certify your genuine distributors

When you allow others to produce, sell, or represent on your behalf, the hardest problem is not the agreement — it is proving to the end customer that this person or company is genuinely authorised. Jitsuin solves that directly.

You can issue a Jitsuin to any licensee or distributor, certifying — on your verified identity chain — that they are genuine. Anyone who encounters them can verify their authorisation instantly, tracing the chain back to you as the originating authority.

Issue verified authorisation seals to licensees — each one cryptographically traceable back to your identity
End customers can verify any distributor's authorisation instantly — no need to contact you directly
Revoke authorisation at any time — the chain is updated immediately and expired seals become verifiably invalid
Build a transparent, auditable network of authorised parties — useful for compliance, disputes, and due diligence

Whichever world you work in —
your Jitsuin is ready.

One identity. Verified once. Applied everywhere it matters. Your first 50 seals are free.
