Apologies, only Jr. Members and above can join the signature campaign.
When you say that items are going to be voted on by the community via the blockchain, does that mean that every single product or listing itself is publicly visible? Otherwise, they couldn't be voted on. And can I list an item straight on your marketplace or does there first have to be vote about that?
There will be private listings but by default every listing will be public and can be seen at the marketplace directly. However, in case a seller stops responding to messages or stop shipping orders then this will be publicly visible to all users and buyers who have already placed their orders or potential buyers planning to place order and holding LBC will be able to vote against the seller and once minimum threshold have been reached then final decision will be made based on the seller stats (current + past history), number of voters and LBT (then LBC) held by each of them, considering all these factors item will be removed from the marketplace.
To accept an order sellers needs to have LBC in their wallets that is equivalent to the total price of an order. In case an item is removed, LBC belonging to the buyers that are in escrow will be refunded to them whereas LBC in escrow that belonged to the sellers will be burned. Demand for LBC goes up whenever an item is removed from the marketplace. However, sellers have a strong incentive to ensure that their listing doesn't gets removed with any pending orders.
