Blockchain

I am writing a blockchain that involves smart contracts, NFT's, FHE for all transactions. Implantation of privacy wallets for selling and buying collectible goods online. Say you want to sell an item on our platform.By authenticing a item through us upon verification you will be issued a NFT that acts as a receipt and certificate of authentication which follows the item in each future transaction. This I believe will bring back a sense of trust back in buying and selling of collectibles online. Furthermore by authenticing with AI it will be same day shipping to the buyer as we act as a escrow service free.and the shipping will be half the cost of the regular shipping cost being an indigenous business we save on shipping costs. 

What do you think any idea's to add.
