Secure P2P File Transfer on Starknet 🔐

A revolutionary decentralized file sharing application built on Starknet that combines the power of P2P connections with blockchain security.

Why This Matters? 🤔

Traditional file sharing solutions face numerous challenges in today's digital landscape. Here's how our solution compares:

Feature	Traditional File Sharing	Centralized Blockchain Solutions	P2P Starknet File Transfer
Server Costs	High maintenance costs	Medium-high gas fees	Minimal (only for permissions)
Data Storage	Centralized servers	On-chain (expensive)	P2P (no storage costs)
Security	Vulnerable to server attacks	Smart contract dependent	Dual-layer (P2P + Blockchain)
Privacy	Limited by server policies	Public blockchain data	Private P2P connections
Access Control	Database-dependent	Smart contract-based	Smart contract + Security code
Scalability	Server-limited	Blockchain-limited	P2P network scalability
Single Point of Failure	Yes (central server)	No	No
Cost for Users	Subscription/Storage fees	High gas fees	Minimal gas fees
