This article examines the role of digital technology in enabling and enhancing democratic practices and forms of governance. It contributes to emerging debates on democratic innovations by proposing a novel theoretical account of decentralized participatory democracy. To develop our account, we draw on the experience of two EU-funded projects, D-CENT and DECODE, which produced innovative citizen participation platforms and digital public infrastructure. Bringing democratic theory into conversation with critical data studies and the new municipalism movement, we theorize how these projects advanced three political aims: organizing political communities to build collective power, empowering citizens through direct participation in decision making, and transforming political institutions. The article then analyzes the strengths and limitations of these projects to draw lessons for policy makers and practitioners for future digital democratic experiments.
