• Abstract:

  In This Modern Era, We Have Faced A Lot Of E-commerce Scams, So We Have Introduced A System To Reduce The This Scam. Wehave Built A Dual Escrow Mediation Where Both The Buyer And Seller Have To Initiate 10% Of The Deposit Inside The Escrow Wallet For Cash On Delivery For The Prepaid, The Buyer Has To Pay The Whole Amount Price, And That Price Will Be Locked In The Escrow. The 10% Of The Deposit, Which Is Called The Security Money, Will Be Deposited By The Seller Into The Escrow Wallet. In This System, The Agent Delivery Acts As A Judge, A Genuine Return Request And The Unreasonable Request Will Be Handled By The Agent Delivery. If The Return Request Was Unreasonable By The Buyer, Then A Penalty Will Be Given To The Buyer.If The Agent Judges A Return Request As Unreasonable, Then 10% Of Productprice Is Redistributed To The Three Parties The 3% Of The Amount Goes To The Agent For Delivery As A Service Fees. 7% Of The Product Price Is Transferred To The Seller As A Compensation And Then The Remaining 90% Of The Product Price Is Returned To The Buyer. Because Of The Unreasonable Request, The Buyer's Reputation Score Will Be Reduced To 0.1 Leading To A 9.9 Reputation Score. Whenever The Buyer Or Seller Tries To Scam, Their Reputation Score Will Be Reduced To 0.1 . The Reputation Score Will Help Both The Buyer And Seller To Identify That The Particular Party Have Scammed. The System Was Built Using Python3.11+, Streamlit, FastAPI, Uvicorn, And The Requests Library. The System Results Confirm The Escrow Lock, Dual Escrow Mediation, Penalty Redistribution And Repetition Scoring.
