Secure File Sharing with Blockchain Technology
Upload, encrypt, and securely share files using Solana blockchain and IPFS. Your files are encrypted with military-grade encryption and accessible only to those you authorize.
How It Works
Our platform combines blockchain technology with advanced encryption to provide a secure file sharing experience.
Secure Upload
Files are encrypted in your browser before being uploaded to IPFS, ensuring that only you have access to the original content.
Selective Sharing
Share access with specific Solana wallet addresses. Recipients will see shared files when they connect with their wallet.
Encrypted Access
When accessing files, the system verifies permissions on the blockchain before allowing decryption and download.
Technical Architecture
Our platform leverages cutting-edge technologies to ensure maximum security and privacy.
Client-Side Encryption
Files are encrypted using AES-256 encryption directly in your browser before being uploaded. The encryption key never leaves your device, ensuring that your files remain private even if the storage is compromised.
IPFS Storage
We use the InterPlanetary File System (IPFS), a distributed and decentralized storage network. This ensures your files have no single point of failure and are accessible from anywhere in the world.
Solana Blockchain
File permissions and access controls are recorded on the Solana blockchain. This creates an immutable record of who has access to which files, preventing unauthorized access modifications.
Key Management
Your Solana wallet serves as your authentication mechanism. The public/private key pair from your wallet is used to securely manage access to your files without requiring additional passwords.
The Complete Process
A step-by-step breakdown of how files are shared and accessed securely.
Step 1:Connect Wallet
Start by connecting your Solana wallet. This authenticates you on the platform and provides the cryptographic keys needed for secure operations.
Step 2:File Encryption
When you upload a file, it's encrypted in your browser using AES-256 encryption with a unique key. This ensures that the file is secure before it ever leaves your device.
Step 3:Upload to IPFS
The encrypted file is uploaded to IPFS, a decentralized storage network. IPFS returns a unique content identifier (CID) that points to your file.
Step 4:Blockchain Registration
The file's metadata and access permissions are registered on the Solana blockchain, creating a tamper-proof record of ownership and authorized access.
Step 5:Share with Recipients
Share access with others by entering their Solana wallet address. This updates the blockchain record to grant them permission to access the file.
Step 6:Recipient Access
Recipients connect their wallet, and the app checks the blockchain to verify their access rights. If authorized, they can download and decrypt the file.
Step 7:Verification & Audit
All access attempts are verified against the blockchain record. This creates an auditable trail of who accessed what and when.
How Recipients Access Files
Understanding how recipients discover and access files shared with them.
For Recipients
When a file is shared with your Solana wallet address, the sender adds your address to the file's access list on the blockchain.
Currently, there is no automatic notification system - you'll need to check your dashboard after logging in.
To discover files shared with you, connect your wallet and navigate to the 'Shared With Me' section of the dashboard.
The app verifies your permissions against the blockchain record before displaying files you have access to.
When you download a file, it's decrypted in your browser using your wallet's cryptographic keys.
Future Enhancements
On-chain notification protocol that will alert users when new files are shared with their wallet address.
Email notification system (requires linking an email to your wallet address).
In-app notification center with unread indicators for new shared files.
Mobile app with push notifications for instant alerts when files are shared.
Optional multi-signature requirements for accessing highly sensitive files.
Integration with popular wallet providers for streamlined notification delivery.
