The City of Zug made international headlines in 2018 when it became the first municipality in the world to conduct a blockchain-based consultative vote. While the trial was limited in scope, it signalled a philosophical alignment between the canton’s blockchain ecosystem and its governance institutions — a willingness to apply the technology that Zug hosts to the democratic processes that define Swiss political life.
The Digital Identity Initiative
In 2017, the City of Zug launched a blockchain-based digital identity system, allowing residents to register a self-sovereign digital identity on the Ethereum blockchain. The system was developed in collaboration with local blockchain companies and was designed to demonstrate the practical applicability of decentralised identity concepts.
Residents could use their digital identities to access municipal services, participate in surveys, and — in the 2018 trial — cast votes in a non-binding consultative process. The system demonstrated that blockchain-based identity could function in practice, though adoption remained limited.
The Voting Trial
The June 2018 blockchain vote asked Zug residents to express opinions on two local matters: whether they supported the city’s digital identity initiative and whether they would support blockchain-based governance tools for future consultations. Approximately 72 registered digital identity holders participated — a small number that reflected both the experimental nature of the exercise and the inherent conservatism of Swiss voters regarding changes to democratic processes.
The trial demonstrated the technical feasibility of blockchain voting while highlighting the social and political challenges. Swiss citizens value the secrecy, simplicity, and institutional trust embedded in their traditional voting system. Any blockchain alternative must meet or exceed these standards — a high bar that no current technology has fully achieved.
E-Government Evolution
Beyond voting, the Canton of Zug has invested in digitising government services more broadly. Business registration, tax filing, permit applications, and social security administration are increasingly available through digital channels. While these initiatives do not necessarily use blockchain technology, they reflect the same modernisation ethos that the blockchain voting trial embodied.
Lessons
Zug’s e-government experiments offer important lessons for the broader blockchain industry. First, technology alone is insufficient — institutional trust, user experience, and democratic legitimacy are equally important. Second, experimentation in governance must proceed cautiously, with citizens as willing participants rather than subjects. And third, the gap between technical possibility and social readiness is often wider than technologists anticipate.
The Canton of Zug continues to explore how technology — blockchain and otherwise — can enhance public services and democratic processes, maintaining its position as a laboratory for governance innovation.
