Shugora

Shugora (书阁楼) is a blockchain-powered e-book publishing and marketplace platform built on 0G infrastructure. It gives authors verifiable ownership, on-chain licensing, and anti-piracy protection through personalized PDF watermarking — while keeping the buying and reading experience completely familiar for everyday users.

Authors upload PDF e-books which are registered on 0G Storage with a canonical content hash. When a reader purchases a book, an on-chain license entry is created on the 0G Aristotle mainnet via our LicenseRegistry smart contract, and a uniquely watermarked PDF is generated for that specific buyer.

For readers: email signup, normal checkout, download a PDF, read in any standard app. No wallet required. No blockchain friction.

Tagline: Buy like normal, own like never before.

Built the full Shugora platform as a solo non-technical founder using vibe coding on Replit and Cursor within 24 hours.
