The IOTA Foundation's Berlin-based smart city initiative leverages distributed ledger technology to create secure, feeless micropayment and data exchange layers specifically designed for Internet of Things devices operating within urban environments. Unlike traditional blockchain systems that require energy-intensive mining and impose transaction fees, IOTA's Tangle architecture enables instant, cost-free transactions between machines, making it economically viable for the high-frequency, low-value exchanges characteristic of IoT ecosystems. Practical applications being developed and tested in Berlin include automated parking payments where vehicles communicate directly with smart parking infrastructure to settle charges without human intervention, peer-to-peer energy trading between smart buildings equipped with solar panels and battery storage, and verified environmental data sharing where sensor readings are cryptographically authenticated to ensure data integrity for regulatory and planning purposes. The initiative also explores supply chain transparency applications, using immutable data trails to track goods and materials through urban logistics networks. By providing a trusted, decentralised data layer, IOTA addresses critical challenges around data sovereignty, privacy and interoperability that frequently hinder smart city data sharing between different stakeholders and systems. The Foundation collaborates with Berlin's municipal authorities, research institutions and technology companies to pilot these applications in real urban settings, generating evidence about the practical benefits and limitations of distributed ledger approaches in city contexts. The IOTA smart city initiative demonstrates how blockchain-adjacent technologies can underpin trusted machine-to-machine transactions at urban scale, potentially enabling new models of automated city services, decentralised resource management and transparent public infrastructure operations across smart city ecosystems.
