Blockchain Based Car-Sharing Platform

The car-sharing market is constantly growing and recently it has become even more popular than car ownership. However, classic car-sharing system is based on a centralized database server which can often lead to hacker attacks or password leaks. Moreover, in a classic car-sharing system, the owners of the cars can misuse customers' data. As seen nowadays from a lot of use cases, the best solution to these problematic issues is to use blockchain technology. Blockchain as decentralized, immutable, public ledger provides the customers with security that is impossible to tamper. The aim of the proposed solution is to create and implement peer-to-peer short term car-sharing application based on blockchain technology and smart contracts. For the implementation of smart contracts, Solidity programming language is used. Solidity works with Ethereum blockchain. The key novelty of the article is introducing a peer-to-peer car sharing service without a central authority, what reflects a decrease of costs and increase of data transparency in that system. Also token based solution gives us ability to cover business-to-business (B2B) and business-to-customer (B2C) use cases.
