The 100-Year Vault · 1,000-Year Vault in perpetuity-friendly jurisdictions
Sealed today. Verifiable in 3026.
Every document sealed in Zentru is hashed, signed, rolled into a daily Merkle root, and anchored across Bitcoin, Ethereum, and Stellar. The verification spec is open-sourced and escrowed on-chain. If we disappear tomorrow, your proof doesn't.
Multi-chain anchored
Bitcoin (via OpenTimestamps), Ethereum calldata, Stellar manage_data. A receipt is Vault-confirmed when two or more chains carry the same daily Merkle root.
Open-source verifier
lovable-vault, MIT-licensed, on npm and GitHub. Verifies any certificate offline using only its embedded JWK and a cached block header snapshot.
Escrowed spec
The byte-level Vault Spec is published, hashed, pinned to IPFS, and itself anchored on Bitcoin. Every certificate pins the spec version that sealed it.
Verify any Zentru document in 10 seconds
Drag the original document here. Your browser computes its SHA-256 and checks for a matching sealed receipt. No upload, no account.
Verify any sealed document
Drop a file. It is hashed in your browser — never uploaded. We look up the matching receipt and verify its Ed25519 signature.
Jurisdiction horizons
The Vault Horizon matches the legal lifespan of the governing trust under each jurisdiction's rule against perpetuities. West Virginia, South Dakota, Alaska, Delaware, Wyoming, and New Hampshire support the full 1,000-year horizon.

A promise, not a marketing line
We could disappear tomorrow. Your proof wouldn't.
The verifier is open source. The spec is escrowed on Bitcoin. The anchors live on three independent chains. The cryptography is standard. Nothing about verification requires Zentru to exist.
