Block-Shop

Decentralization of reselling of products with blockchain.

Comment

Inspiration

To make the reselling of things among peers thereby eliminating charges that the merchants charge and also verifying the products with the help of nearby peers of the seller

What it does

Consider person A is seller and B is buyer.

  • A puts a product on the site.
  • B wants to buy it. But B wants to eliminate the charges inculcated by the middle merchants like olx or droom.in(in case of automobiles). B also doesn't want to compromise with the quality of the product.
  • Thus, we offer a reward( in terms of a currency or ether ) to the peers in the vicinity of the seller A to check the product in person for buyer B.
  • The first person( let's say C ) who approaches A records the quality and features of the product and makes a statement whether it is good to buy or not which is to be verified by other peers.
  • The following people approaching A after C( say D, E ), counter check the statement of A so as to not have any kind of fraud. They also get a part of generated currency on counter checking the first person's decision so that they won't be without reward.
  • If majority of people( minimum 6-7 ) confirm about the quality of product, then we add the transaction and thus many transactions are combined to form a block which we append in our blockchain.
  • If a peer tries to fraud, we have a factor called 'Reputation', which would eventually decrease if he tries to do deceit.

How we built it

We created a blockchain using the Flask( Python ), used mongoDB and combined the blockchain concepts to achieve the same.

Challenges we ran into

We had to write a blockchain from scratch without using any library, so that part was the challenging one.

Accomplishments that we're proud of

We were able to make a prototype platform within time and make it work so that's the major thing that we accompolished. Having created the blockchain from scratch was pretty time consuming but somehow it fell into place.

What we learned

We learnt how the peer to peer communication happens and how blockchain can be used to decentrilize systems and keep things transparent.

What's next for Block-Shop

We have made it by giving example automobile. It can be scaled easily for nearly every product and thus we can reduce the charges inculcated by middle merchants and provide a quality product to buyer.
