<p>Here in this scenario as per my view if you are storing transaction hash then you must check that if buyer's Address (sender Address) and Reciver's Address are same in that transaction then you must not accept it to your system.

# Detecting Wash Sales/Transactions

(Asked by: username_0 on 2018-06-30)

I run a site which is essentially an e-commerce platform where buyers connect with sellers and all transactions happen in Bitcoin. I worry about sellers on the site continuously buying their own items on the site to gain visibility (more sales means higher ranking on the front page).

Is it possible to detect whether an incoming transaction originated from the same bitcoin wallet?

But I'm not sure how this would work with wallets where each payment generates a new address from a master public/private key pair.

It is not possible to determine if multiple addresses belong to one wallet, whether it is a deterministic wallet or not.

At best, you can do some form of chain analysis that traces UTXOs back along the chain until you find a common root. For most transactions in a single wallet, there will usually be a convergence point of the coins. However, this is not an exact science, and the results may not be of a high enough confidence to be certain it is happening.
