Business Verification DApp is a decentralized on-chain registry and review system built with Web3 technologies. Businesses register their details via a connected wallet and go through an admin-moderated approval flow before becoming publicly listed. Once approved, verified businesses appear on the platform and are open to user reviews stored immutably on-chain. The system eliminates review manipulation and fraudulent listings by leveraging blockchain transparency and auditability, creating a trustless reputation layer for businesses.
What this app does
Think of it as a trust registry. Instead of a private company (like Google or Yelp) owning the data, the information is stored on a blockchain—a public, digital ledger that no single person can secretly change or delete.
For customers (the public)
Find legit businesses: you can browse a list of companies that have been officially vetted.
See the stats: check how much money a company has raised and see their quality score.
Leave reviews: you can rate businesses. To prevent spam, the system makes you wait a certain amount of time between reviews (a cooldown).
For business owners
Apply for a badge: you submit your business details to prove you are real.
Build a reputation: once an admin approves you, your profile becomes public, showing your funding and your customer ratings.
How it stays safe (the gatekeepers)
The app does not let anyone do whatever they want. It uses different levels of authority to keep things honest:
Managers: people who check applications and green-light businesses for the public list.
Verifiers: people whose job is to double-check that a business's claims are true.
The emergency brake: if something goes wrong (like a hack or a bug), a pauser can freeze the entire app instantly to protect everyone.
How do you log in?
There are no usernames or passwords. Instead, you use a digital wallet (like MetaMask). Your wallet acts as your ID card. When you want to leave a review or register a business, you sign it with your wallet. This proves it was really you and makes the action permanent.
