Facebook’s Libra Blockchain and Move Smart Contracts
Find centralized, trusted content and collaborate around the technologies you use most. Connect and share knowledge within a single location that is structured and easy to search. I have been thinking about Libra, and have been reading on how to really track a transaction not in forensics way, but in e-commerce way. Let me explain a bit here. Let's say Bob is a guy who sells products, and Alice is a customer of Bob.
Bob has built an online platform where he can accept payments in Libra. In Libra docs here , it says a transaction consist of,. Bob won't have Alice's address stored when Alice makes a payment especially if Alice is a new customer. Conversely, a third person Jenna could be making a purchase with the same SKU at the same time as Alice. If a Libra transaction only consist of sender's account address, How does Bob track that his transaction with Alice, and the subsequent payment he received from Alice, is actually Alice's and not Jenna's?
Note that he won't have these account addresses on file, especially if both are new customers. A simple way would be to assign a transaction ID as some sort of metadata when Bob requests that each of them pay him, so Bob can track against that transaction ID.
But is this even possible? I'm sure this exists in some form or another, since we have Bitcoin payment systems. Any clarification on this would be very helpful! Bob generates his master merchant wallet. From this prrivate key he can generate many other wallets, all accessible from that same private key. For each new customer Alice, Jenna he will generate one of these new wallets trivial to do, with a nearly infinite amount of wallets that Bob can create from just his one private key.
With a newly generated wallet, he will share the wallet address with one customer and take note that he sent Alice the address for wallet 1A and wallet address 1B to Jenna. Then, using a blockchain explorer he can know that when 1A receives funds, that it was in fact Alice who paid him.
You may have seen in some brick and mortar locations when they have to the option for customers to pay with cryptocurrency, that the customer scans the merchants QR code public facing wallet address and sends to it. Each time a customer sends to the merchant address, the merchant should be generating a new wallet to display to the next customer for reasons of both privacy and tracking which customer's have paid what.

Currencies have been around for thousands of years as a way to replace the bartering system and so that people can ascribe a unified value which they can exchange with others. Many cultures around the world developed the concept of commodity money i. Eventually metals were favoured and used as money because they were more durable. For example the Egyptians used gold bars of differing weights and the Mesopotamians used silver. During the seventh century in China, the concept of the banknote was developed, though paper money was only formally introduced around the 11th century. The reason for this was so that merchants and wholesalers did not want to carry heavy copper coins in larger commercial transactions. Bitcoin was revolutionary at the time because it was created as a decentralised digital currency without control by any bank or authority.
