Overhaulin’ – A Blockchain-Based Auto Auction System 
 
Overhaulin is being made, while keeping the perspective of a customer as a buyer/seller, admin 
perspective for managing car data, and maintenance perspective for managing car repair log. There 
are three views of this app – Customer View, Admin View, and Maintenance Admin View. Our 
system will help facilitate customers looking to buy or sell a car. A seller can post ads to sell a car 
and buyers can bid openly against one another, with each subsequent bid required to be higher 
than the previous bid. Bidding will be open for a certain time after that car will be sold to the 
highest bidder. Immutability of each bid will be registered to make the tracking and verification of 
bidding history easier; this bidding process should be done using smart contracts, The use of smart 
contracts ensures that sensitive information is validated and protected ensuring data security. 
Moreover, the blockchain-based solution would enable the auctioneer to directly connect with 
many potential bidders without intermediaries. No bid cancellation’ feature was enabled to ensure 
a fraud-free Auction. Customers will also be facilitated through a car recommendation system, to 
cater to their unique needs. He can also search for the different cars of their own choice. The 
maintenance/accident log of the car will be stored on the blockchain to help customers verify the 
repair history of the car. And for the admin view, he will be responsible for adding the car data to 
the blockchain also it facilitates the admin to generate a sale receipt, approve ads posted by 
customers, start bidding and stop bidding also he can announce a bid winner.
