Search Businesses by Decentralized Reputation

Ratings and reviews validated by payments on blockchain.
No third party required to authenticate reputation data.

Chlu (pronounced clue) means reputation in Irish

The Problem: Search For Products and Services is Broken

Finding businesses, products and services that we can truly trust, is a complicated, fragmented and unsolved problem.

  • Where exactly are these reviews coming from? Can they be trusted?
  • 40% of product searches today actually start on Amazon, not Google.
  • Online reputation based on traditional reviews and ratings has been proven to be open to massive manipulation.

Chlu solves the Search problem by first solving the Reputation problem

Chlu Search Powered by Chlu Reputation 3.0

Online reputation management is deeply flawed, for example:

  1. It’s too easy to manipulate the current systems.

    Because ratings have real world financial consequences, there are substantial incentives to cheat the system and game your reputation or the reputation of competitors.

  2. Reputation isn’t portable, instead it is locked inside many individual walled gardens; your reputation on eBay is meaningless on Amazon.

    There is huge value in having your reputation established and portable across all ecosystems, and having no single organization be the gatekeeper that must be trusted. The future is trustless!

System Required Proof of Purchase Walled Garden
Chlu Yes No
Amazon Optional Yes
Ebay Yes Yes
UpWork Yes Yes
Etsy Yes Yes
Shopify Third-Party Trust Yes
Google Seller Ratings Third-Party Trust Yes
Yelp No Yes

Chlu solves these problems by offering a truly open, trustless, free to use reputation system that is backed by payments received on blockchains. There is no charge apart from the small fee paid to the blockchain miners (gas). The system is open to use for anyone and portable across all marketplaces.

Chlu Reputation Features

  • Feedback tied to payments

    Proof of Payment: Customers can leave feedback only if they made a payment to the vendor.

  • Verified Payments

    Proof of Payment Requested: Every payment made can be verified as a response to a payment request from the vendor.

  • Zero Fees

    The only fees in the system are those charged by blockchain miners.

  • Private Feedback

    Feedback is private to the vendor. Vendors can share their reputation with any marketplace, including their own websites.

  • All or Nothing Reputation

    Vendors can not selectively hide a review. Once they share their reputation with a marketplace their entire history is available to the marketplace.

  • Multiple Reputation Scores

    Marketplaces are free to compute their reputation score for a vendor using all Chlu data available.

  • Open Access

    Anyone can use the reputation system as a vendor, customer or marketplace. No central authority controls access to the platform. Chlu is decentralized

  • Extensible

    Marketplaces can store detailed customer reviews using an extensible storage format and aren’t limited by a predefined review data structure. This is similar to the way NoSQL presents data to users.

Chlu Reputation for Vendors

  • Build a reputation backed by payments made directly to you
  • Keep your reputation history public or share only with the marketplaces you choose
  • Build your reputation from your trading activity across all marketplaces
  • Get paid over blockchain, for near instant payments and low fees. (Chlu does not charge any commission fees)

Reputation’s Walled Garden Problem

The Past

  • All trade history is locked inside walled gardens
  • Acme Inc. struggles to trade on different marketplaces

The Future

  • Permanent history of trades
  • Accessible to anyone with permission from Acme Inc.
  • Owned by Acme Inc., not the marketplace

How Chlu Reputation Works

No trusted entity required

  1. Vendor creates payment request and shares it with the customer. All reputation data on Chlu must be backed by this payment request.
  2. Customer clicks on payment request link to open their Chlu wallet.
  3. Customer makes a payment.
  4. The payment processor makes the payment through blockchain
  5. The payment request is saved along with the payment transaction ID.
  6. Customer leaves feedback for vendor once item is received.
  7. Each review is saved on an immutable, decentralised system and is backed by the proof of payment that is in turn backed by a proof of payment request.
  8. Feedback is shared with all the marketplaces the vendor has enabled access for.

Chlu Token Economy

  1. Tokens generated by customers writing reviews and ratings
  2. Amount rewarded is inversely proportional to total volume of written reviews in that hour
  3. Tokens also generated when vendors receive payments
  4. To maintain liquidity Chlu automatically and transparently balances ad spend vs. reward for writing reviews on an hourly basis

Developer Ecosystem

An open source ecosystem supported by protocols published in the public domain.


  • Chlu provides a set of protocols for customer and vendor wallets as well as marketplaces.
  • These reference implementations are open sourced.
  • Chlu does not charge any commission on top of the blockchain miners fees.
