The main benefit is that it keeps a ledger that Walmart can use to track transactions to see how many people use the system on a daily basis and what they can optimize it for to maximize profits. (Walmart may be able to do this already but can isolate one sector of its retail using Crypto)
(Example Walmart knows one location is very popular so they do more advertising there than in places where they receive lower income places or the reverse if they think they can take market share).
In addition the benefit of removing the cashier from the transaction may reduce some stealing. (Example Cashier in Oklahoma knows Cashier in Colorado Sends some money every couple of months to Cashier B and quits before the end of the year accounting is sent no one knows who sent what the money is lost long siphon)
Vs: Cashier X sent Amount A to Cashier Y (Blockchain trackable) and they realize it eventually when they do the accounting and can trace it to an individual.
I think your right given how Walmart operates might not seem too practical now but who knows in the future, it just seems a bit cheaper to have a few miners and a transaction log that they can have in all stores to determine demand for it, than the cost involved in setting up a new system from scratch (Unless they are using moneymart/Western Unions stuff) in all their Walmart stores. Cutting the bottom line and save money is the walmart motto, so that is where I see some cryptography benefits applying.
Makes sense, it would indeed be an easy way to keep an accurate and foolproof ledger. Thanks for your answer.
The best algorithm for them would probably be PoS with all the coins centrally premined; gives the benefits you mentioned, without risk of an external 51% attack and no need for miners.
Thanks was wondering if it made sense there for a bit was feeling a bit technical
Gets tricky not turning it into a white paper
Aka Alice said Hi to Bob and bought apples while Carl watching it tried to steal these apples but was blocked by a Cryptographic chain of transactions longer than his ^_^
A POS with no mining but just sending would work, wonder if that can be coded technically
100% of Coin Distribution, Secure Internal System of Transmission, Instant transaction and processing with Unique addresses but no miners
Decentralized and still sending without someone mining makes me wonder.
If not a central premine from a head office or two to ensure not single node of failure would work as long as it connects to the general walmart retail network, which it should because if it didn't Western Union or Moneygram or Walmarts own service would be affected as well so non-factor.
