Peer-to-Peer Ridesharing Using Blockchain – Cryptopolitan

Peer-to-peer (P2P) ridesharing, a concept swiftly gaining traction, has been redefining the urban transportation landscape. This innovative approach to ride-hailing cuts through the clutter of conventional models and streamlines the process of connecting passengers with drivers.

Peer-to-peer ridesharing, unlike traditional ride-hailing services, introduces a direct connection between individuals seeking rides and those willing to provide them. It eliminates the middleman, offering a more cost-effective and efficient transportation. Passengers can request rides, and nearby drivers can respond promptly, often resulting in shorter wait times and lower fares.

This phenomenon has gained immense popularity due to several factors. First, it taps into the sharing economy concept, emphasizing the efficient utilization of resources. Second, P2P ridesharing caters to the ever-growing demand for convenient, on-demand transportation. It allows individuals to efficiently utilize their vehicles as an income source or find affordable rides. 

The exponential growth of P2P ridesharing platforms has not gone unnoticed by technology innovators. Blockchain technology, known for its security and transparency, has been integrated into these platforms, promising to revolutionize the industry. Blockchain ensures that transactions are secure and verifiable, enhancing trust between drivers and passengers.

Challenges and Limitations of Traditional Ridesharing Platforms

Traditional ridesharing platforms face several challenges and limitations that have prompted exploring alternative solutions like blockchain-enabled P2P ridesharing. 

Centralization and Control

Traditional ridesharing platforms operate as centralized intermediaries, exerting significant control over pricing, policies, and user accounts. This centralization can lead to a lack of transparency and fairness in operations, with little room for user influence.

High Commission Fees

These platforms typically charge drivers significant commission fees, reducing their earnings and increasing passenger costs. This financial burden can deter both drivers and passengers from using the service.

Privacy and Data Concerns

Users are required to share personal information with the platform, raising concerns about data privacy and security. Instances of data breaches and misuse have eroded trust in the handling of user data.

Surge Pricing and Fare Inflation

Surge pricing during peak hours or high-demand periods can result in inflated fares, leading to dissatisfaction among passengers. This pricing model needs more transparency and predictability, making it easier for users to plan their rides economically.

Limited Driver Earnings

Drivers on traditional ridesharing platforms often need help to earn a sustainable income due to commission fees, maintenance costs, and fluctuating demand. This can lead to high driver turnover rates and a potential shortage of available rides.

Blockchain-Based Peer-to-Peer Ridesharing Architectures

This section provides insights into prominent proposals for Peer-to-Peer Ridesharing Architectures. Each of these architectures explores unique features and approaches to enhance the ridesharing experience.


Block-V introduces a built-in reputation system aimed at ensuring ride fairness. Every aspect of the ride is permanently recorded on the ledger, accessible to all participants in the peer-to-peer network. This approach not only prevents identity theft but also allows authorities to verify complaints by checking the ledger.


Block-VN focuses on a distributed vehicle network architecture. It monitors the evolution of the vehicle network with changing paradigms. Vehicle departments transmit registration details to a revocation authority, which subsequently informs the distributed blockchain about all relevant information regarding regular and miner vehicle nodes.


B-Ride implements a reputation model that rates drivers based on their past behavior, enabling riders to make informed choices. To safeguard rider/driver privacy, confirmations utilize zero-knowledge proofs. The platform also introduces a pay-as-you-drive philosophy to ensure fair payment.

Green Ride

Green Ride promotes environmental responsibility through decentralization. It comprises two components, a centralized code running on Google Cloud App Engine and decentralized GRTs. This approach encourages businesses, educational institutions, and government agencies to reduce their annual carbon footprint.


PEBERS is a ride-hailing service built on Ethereum. Users are assigned unique IDs to search for rides within the blockchain ledger using a fog mechanism. The data storage relies on Distributed Ledger Technology, ensuring decentralization. A Consensus Protocol is in place to maintain data consistency.


O-Ride prioritizes user privacy and optimizes the Symmetric Homomorphic Encryption (SHE) technique to reduce bandwidth requirements and processing overhead. It offers features like credit card payments, lost item retrieval, and traceability in case of criminal activities.

Ride Matcher 

Ride Matcher introduces a unique architecture where clients don’t rely on a central database to find rides. Instead, it employs a peer-to-peer approach, facilitating the formation of ridesharing groups online. Nodes independently search for matches based on route compatibility, ensuring a decentralized and efficient ridesharing experience.

How a Blockchain-Based Ridesharing System Works

The process is streamlined and secure in a blockchain-based ridesharing system, revolutionizing the traditional ridesharing experience. Here’s a comprehensive overview, combining insights from both sources:

  1. Registration and Identity Verification: Riders and drivers initiate their journey on the blockchain-based platform by creating a digital identity. This involves providing essential personal information, such as names, phone numbers, and payment details. Blockchain technology ensures the utmost security for storing this sensitive data.
  1. Ride Request: When passengers require a ride, they submit a ride request specifying the pick-up and drop-off locations, preferred vehicle type, and their proposed fare. These details are recorded securely on the blockchain, ensuring transparency and integrity.
  1. Driver Selection: An intelligent algorithm matches the rider’s requirements with a suitable driver. The driver can approve or decline the ride request, providing flexibility within the system.
  1. Ride Confirmation: A smart contract is activated upon driver acceptance to commence the ride. The passenger is promptly informed about the driver’s arrival and the expected arrival time, enhancing the overall user experience.
  1. Ride Execution: The ride unfolds according to the agreed terms. Passengers and drivers can monitor the route using the platform’s integrated navigation system, ensuring smooth navigation.
  1. Payment and Rating: Post-ride, the smart contract automates the payment process, calculating the fare based on distance and time. Digital currency flows seamlessly from the passenger’s digital wallet to the driver’s, eliminating the need for intermediaries. Both parties can rate and review each other, contributing to the platform’s trust-building mechanism.
  1. Trip Data and Transparency: All crucial trip data, including routes, fares, and ratings, is securely and immutably recorded on the blockchain. This transparency minimizes disputes and fosters accountability within the network.
  1. Token Rewards: Many blockchain-based platforms employ tokens as incentives. Drivers can earn tokens as rewards for exceptional service, which they can later redeem for various perks, enriching the platform’s ecosystem.
  1. Dispute Resolution: In the event of a dispute between a rider and a driver, the platform offers mediation services to resolve. If an agreement cannot be reached, the platform may issue a refund, ensuring fair and efficient conflict resolution.
  1. Payout: Drivers can transfer their earnings from their digital wallet to their bank account.

Smart contracts and digital currency streamline payments, reduce fraud risks, and eliminate the need for centralized oversight. In case of disputes, a decentralized arbitration process involving independent arbitrators ensures fairness based on smart contract provisions and relevant evidence. 

This holistic approach makes blockchain-based ridesharing systems a secure, efficient, and transparent choice for both passengers and drivers.
