Verification, provenance, and operational continuity for institutions that hold what matters. Continuous. Sovereign. Independent of any single principal.
Every institution that holds records of consequence runs the same risk under different names. The record exists. It is real. It is necessary. And it is held by one person, on one device, in one place — fragile against that person's absence, exit, or end.
No principal. No operator. No AI — including this one — can alter what entered the register.
Every record that enters the SENTYAL register carries a sequence number, a timestamp, and a cryptographic hash of the entry and everything that preceded it. The chain is unbroken from the first entry to the last.
No entry can be silently altered — any modification breaks the hash chain and is immediately detectable. No entry can be deleted — the append-only architecture has no delete operation at any permission level. The record is independently verifiable by any party, at any time, without SENTYAL's involvement.
This is what makes authentication possible. In art, in music, in finance, in defense, in healthcare — the register is the difference between a claim and a fact.
Galleries, artists, collectors. Provenance research, attribution opinion, room-by-room inventory, exhibition catalogues, sourced documentation.
Zero commission on artwork sales. The records outlast the principal. The gallery operates continuously — inquiries answered, catalog maintained, provenance verified — independent of who is in the room.
Five additional markets are structured and ready for deployment. Each takes a dedicated team, its own pricing, and activation by request.
Any market not listed is taken by request. Scope and pricing built to the specific characteristics of that sector.
