nStamp lets users create tamper-proof, timestamped records on the NEAR blockchain. It works by generating a hash (digital fingerprint) of any data, such as form submissions or AI outputs, and anchoring it on-chain with a NEAR account and timestamp.
🔐 Key Features
-
Verifiable: Anyone can confirm the data hasn’t changed
-
Private: Only the hash is stored; the original content stays encrypted
-
Trustless: No third parties needed; proof lives on-chain
💡 Use Cases
-
Certify AI-generated responses
-
Prove form or document submissions
-
Anchor digital evidence or IP drafts without revealing content
🛠️ How It Works
-
User submits content
-
nStamp hashes and optionally encrypts it
-
The hash is written to the NEAR blockchain with a timestamp
-
Anyone can verify by re-hashing the original content
nStamp brings blockchain-level trust to everyday digital actions, using NEAR to keep records secure, verifiable, and user-owned.

The platform's use of encryption ensures privacy and data integrity, making the timestamped proofs tamper-proof and resistant to unauthorized alterations.
zk is the future
nStamp introduces a groundbreaking concept to the NEAR blockchain, allowing users to create encrypted, verifiable, and timestamped proofs of their form submissions.
vitalik says the future is ZK
Check the accuracy of the data
Is this zk technology?
Nice Technology.
zk technology is good
nStamp will be an application that represents breakthrough technology in the future
