This document discusses the benefits of using blockchain technology to improve public transportation systems. It proposes creating a non-profit organization called TransToken to assess how blockchain could be used to harmonize payment systems and data across different public transportation operators. Key benefits mentioned include reducing fees, improving transparency, enabling seamless travel, and providing benefits to operators, authorities, passengers, and other stakeholders. The document outlines next steps such as mapping existing systems, analyzing data and governance requirements, and deploying a proof of concept project. The overall goal is to assess the feasibility of a blockchain-based system to optimize legacy processes and systems in the public transportation industry.
