The PI CHAIN project only focuses on the PI network, and everything we do is to promote the circulation and use of PI. All miners in the world can create their own virtual stores for free, and everyone can publish information about goods or service transactions. All transaction processes such as product information release, product delivery, and product purchase can be conducted on mobile phones, and the way to obtain pi is not just by mining and running nodes. Now you have another option: trade at Pi Chain Mall!
