The shift towards blockchain modularity prompts a reevaluation of decentralized governance models to accommodate the diverse and interconnected nature of modular ecosystems. While traditional governance mechanisms can be adapted to modular frameworks, the decentralized governance landscape requires innovative solutions to promote collaboration and coherence across different layers of the technology stack. Embracing decentralized governance within the modular paradigm presents both challenges and opportunities for stakeholders to shape inclusive and sustainable governance structures that align with the principles of decentralization and innovation. By exploring the evolution of governance in open-source software and emphasizing community engagement, the modular blockchain movement can enhance its resilience and adaptability for future advancements.
