Experience next-generation file archiving with blockchain security
Create a NeoZip archive by compressing your files. NeoZip calculates a unique SHA-256 hash for each file and combines them into a Merkle tree.
When you verify a NeoZip file, the system generates a timestamp certificate and submits the Merkle root to the Bitcoin blockchain via OpenTimestamps.
Use your NeoZip archives to prove when your files existed and that they haven't been tampered with, all backed by the security of blockchain technology.
Any modification to files inside your NeoZip archive will be detected through cryptographic verification.
Anchor your file timestamps to the Bitcoin blockchain, creating immutable proof of existence at a specific point in time.
Anyone can verify your NeoZip files without trusting a central authority, using the open OpenTimestamps protocol.
All data processing happens locally on your device. NeoZip never stores your files or their contents—only secure cryptographic proofs are created.
The NeoZip Portal gives you powerful tools to create, verify, and manage blockchain-secured zip files.
Compress and secure your files with blockchain timestamps to prove when they existed.
Confirm files haven't been tampered with using cryptographic verification methods.
Keep a history of all your NeoZip files and their verification status in one place.
Choose from multiple compression methods including Zstandard for better compression ratios.
100% private processing: All data is processed directly on your computer. The NeoZip portal never stores or has access to your file contents. Only cryptographic hashes are submitted to the blockchain, not your actual files.
