KarsaChain - Eternal Archive (Web3 Storage)
Project Overview: KarsaChain is a decentralized application (DApp) designed to provide permanent, tamper-proof storage for digital assets. By leveraging blockchain technology and decentralized protocols, it ensures that your most important records remain accessible and unverifiable, even if centralized servers fail.
The Challenge (Problem): Centralized cloud storage is vulnerable to data censorship, server shutdowns, and privacy breaches. Once a subscription ends or a provider goes bust, your digital legacy can disappear. There is a critical need for a storage solution that doesn’t rely on a single point of failure.
The Solution (Engineering & Web3):
Immutable Storage: Integrated IPFS (InterPlanetary File System) to ensure files are content-addressed and stored across a decentralized network rather than a single server.
Smart Contract Security: Developed and deployed Solidity contracts to handle metadata and ownership, ensuring that every record is cryptographically verifiable.
Modern Web3 UX: Bridged the gap between complex blockchain logic and user-friendly interfaces using Next.js 15, making decentralized archiving as simple as a standard drag-and-drop upload.

🛠️ Skills Used
⭐ Key Features
On-Chain Verification: Every file upload is cryptographically hashed and recorded on the blockchain.
Immutable Data: Once uploaded to IPFS, data cannot be altered or deleted by any central authority.
Wallet Integration: Seamless connection with MetaMask and other Web3 providers.
Gas-Efficient Contracts: Optimized Solidity code to minimize transaction costs on the network.
