Like your idea - some questions -
1. Support for transacting with other chains?
2. How to prevent malicious marketplace action using the vendor's marketplace signing key. Vendor must have a way to respond on chain by verifying their own private key to invalidate a PoPR from marketplaces using Vs.

Hi aquapanic,

Thanks for taking the time to read our paper. You raise some excellent questions.

1. Chlu does not need a new blockchain, instead Chlu allows reputation data to be saved on IPFS with references from transactions on bitcoin, litecoin, zcash and ethereum. The first three chains allow use of op_return to save a reference to the Review Record and PoPR. This way, Chlu can support payments through as many cryptocurrencies as possible.

2. That is very good point. One way for the vendor to stop a malicious marketplace would be to remove the marketplace's key from the /ipns/vendorname/chlu/keys/pubver/mi/. There is a drawback to this solution, that the vendor's historical reviews from a marketplace can no longer be validated. But if the marketplace is acting maliciously then the vendor would want to disassociate themselves from the marketplace. We'll update the paper to reflect this issue you have raised.

Thanks again for the help.
