Chlu a decentralised reputation system.
Vendor reputation is backed by payments received via cryptocurrencies.
Vendors completely control who can access their reputation data, and marketplaces can not limit access to a vendor's data.
Chlu supports payments with any cryptocurrencies as long there are wallets for that cryptocurrency with support for Chlu.
Chlu enables paying customers to leave reviews and ratings for vendors. The reviews and ratings are saved on IPFS and vendors remain in complete control of their reputation data. Vendors can choose to publicly share them with anyone, or selectively share them with marketplaces where they sell their services and products.
The position paper on https://chlu.io has more details.
Short answer - no one. But there is a team developing the protocols and reference open source implementations of the wallets and services.
There is no smart contract that any one organisation controls.
Chlu requires customer and vendor wallets to provide functionality that enables customers and vendors to leave reviews, edit them later and share them if they want to.
The Chlu protocol specifies the behaviours that wallet providers need to build to provide support for Chlu reputation on their wallet. The protocol specifies the format of messages and when and how the messages are to be exchanged, where the data is to be saved and how this data should be interpreted by wallets.
Yes, any wallet can support the Chlu reputation platform by providing support for the Chlu protocols specified in this repository.
