Attempts to build "crypto cities" have largely failed, with projects like Akon City and Satoshi Island stalling due to ambitious goals and logistical challenges. Experts argue that instead of creating new cities from scratch, the focus should be on integrating blockchain technology into existing urban infrastructures. Ari Redbord of TRM Labs suggests modernizing current systems with blockchain and AI to enhance transparency and efficiency. Kadan Stadelmann of Komodo highlights the difficulties of establishing self-sovereign cities, citing security and governance issues. Instead, Vladislav Ginzburg of OneSource and Maja Vujinovic of FG Nexus propose developing special crypto zones within modern cities like Dubai, where government support and existing infrastructure can facilitate blockchain integration. These zones could serve as regulatory sandboxes to test new technologies and inform broader policy development.
