Seal it. Prove it later.
A public seal for files, statements, and fingerprints on Vaulta. Written once, readable by anyone, and still there when you come back to check.
Public by default. Encrypt a statement first if it should stay private. A hash keeps the file on your device.
Four records, one write
Each one is a Vaulta transaction. Anyone can read it back from a public node. There is no monthly fee to keep it.
Files
Any file type, encoded and written on-chain with automatic selection of the most efficient encoding.
Upload a fileText
Notes, agreements, and messages. Permanent, timestamped, and readable from a shareable link.
Store textHashes
Notarize a SHA-256 fingerprint as proof a document existed at a point in time, without revealing it.
Notarize a hashNotes & folders
Organize on-chain notes into folders and retrieve a whole folder or a single entry by ID.

Sign with the authenticator
Blocksfinity Authenticator asks for a passkey on this device. The key never reaches Blokstorage.
Encode & commit
Your data is encoded in the browser and written into a signed transaction that a node seals into a block.
Retrieve anywhere
Get a public link to the record, served from the chain. No account is required to read it.
A record you can check later
The file, statement, or fingerprint stays in the transaction. Blokstorage does not keep a second copy you have to trust.
Immutable
Once a transaction is sealed into a block it cannot be edited or removed, by us, by you, or by anyone.
Verifiable
Anyone can independently confirm what was stored and when, directly against the public chain.
Censorship-resistant
Replicated across the network's nodes. There is no single server to seize or switch off.
Yours by key
Access is controlled by your wallet keys, not an account a provider can lock, throttle, or close.
Frequently asked
Is my data really stored on the blockchain?
Yes. Your file, statement, or fingerprint is written inside a Vaulta transaction. Blokstorage reads it back from public nodes. There is no separate database holding your data.
Is stored data public?
By default, anything written to the chain is publicly readable. Store only a fingerprint if the file should stay on your device, or encrypt a statement in the browser before you seal it.
What does it cost?
There is no subscription. You add A to your account, then each seal draws from that balance: 0.01 A for text, a hash, or a note, and 0.1 A for a file. You pay when you write. Keeping the record does not add a monthly fee.
Can data ever be deleted or changed?
A confirmed seal cannot be edited. Settings cannot delete a sealed record. That is what makes it useful for proofs and agreements.
Do I need a wallet?
You sign with Blocksfinity Authenticator. The passkey stays on your device. Reading a sealed record needs no wallet.
