Data chain – Blockchain-powered transparent and secure data storage

Summary: Data chain is a blockchain-based application for storing, verifying, and managing data with transparency and decentralization. It operates on Sepolia and Hoodi testnets, enabling users to upload, download, and verify data integrity while preparing for mainnet deployment.

What it does

Data chain stores file proofs on blockchain to ensure tamper-proof, verifiable data without relying on centralized servers. It uses compression and hashing to minimize on-chain data, providing APIs for integration and a Web2-like user experience.

Who it's for

It targets users and developers needing decentralized, censorship-resistant data storage with verifiable integrity and seamless blockchain interaction.

Why it matters

It eliminates single points of failure and unauthorized data modification by replacing trust in centralized providers with cryptographic proof and decentralization.
