BlockChain Technologies in the World of Fashion

Sammanfattning: Blockchain, a solution for different parties to reach consensus in a peer­to­peer (P2P) networks, allows us to distribute data across different entities. Many areas, including financial, health care, eCommerce, marketing, can benefit from blockchain technology. Influencer marketing also takes benefit from the properties of blockchain technology. Most of the time, social media influencers have an” ideal” body, affecting how theproduct they are advertising looks on them, which results in increased returns inonline shopping. Moreover, existing applications are not involving micro­influencers(10,000 ­ 100,000 followers) in the campaigns that brands have created. In order to tackle the mentioned problems, a blockchain distributed size and fit application framework is proposed in this thesis. The framework offers a possibility for micro influencers to participate in the brands’ campaigns. However, micro­influencers are not directly involved in communication with brands. Instead, macro­influencers (over100,000 followers) play a role as a bridge between micro­influencers and brands by creating sub­campaigns of the brands’ campaigns. With the involvement of micro influencers in the proposed framework, they also share their pictures with the same outfit (different body sizes and shapes), which gives potential buyers a better idea of how the same outfit would look on them before they decide to buy. The proposed solution is implemented with smart contracts using Solidity and tested in the Ropstentest network. Testing the smart contract in the Ropsten test network shows that the proposed solution is feasible in terms of financial costs. The proposed framework is not limited to giving the possibility to only brands to advertise products, but it also offers macro­influencers and potential micro­influencers an opportunity to earna reward in exchange for promoting the products of brands. The whole process starting from applying for a campaign to claiming reward is handled without manual intervention.
