Whoever made it. Whatever it is.
Anywhere proof of authorship, priority, or existence matters, a Thappa seal gives you something no screenshot or email ever could: an immutable, independently verifiable record.
Stake your claim before you submit
Seal a manuscript, dataset, or finding the moment it exists — a timestamped, private proof of priority that protects you from being scooped, without revealing the work.
Prove you had the idea first
Seal a spec, a design, or a business plan as a private hash. You hold dated, on-chain evidence you can reveal later — useful for disputes, diligence, and provisional filings.
Stamp authorship at the moment of creation
Seal art, music, writing, or video the instant it's done. A public seal announces authorship; a private one keeps the work under wraps until you publish.
An audit trail for everything that matters
Seal contracts, code releases, board decks, and disclosures. Every record is immutable, timestamped, and independently verifiable — a tamper-proof ledger of what existed when.
