This paper investigates whether Bitcoin can be regarded as a decentralized autonomous organization (DAO), what insights it may offer for the broader DAO ecosystem, and how Bitcoin governance can be improved. First, a quantitative literature analysis reveals that Bitcoin is increasingly overlooked in DAO research, even though early works often classified it as a DAO. Next, the paper applies a DAO viability framework, centering on collective intelligence, digital democracy, and adaptation, to examine Bitcoin’s organizational and governance mechanisms. Findings suggest that Bitcoin instantiates key DAO principles by enabling open participation and employing decentralized decision-making through Bitcoin Improvement Proposals (BIPs), miner signaling, and user-activated soft forks. However, this governance carries potential risks, including reduced clarity on who truly “votes” due to the concentration of economic power among large stakeholders. The paper concludes by highlighting opportunities to refine Bitcoin’s deliberation process and reflecting on broader implications for DAO design, such as the absence of a legal entity. In doing so, it underscores Bitcoin’s continued relevance as an archetype for decentralized governance, offering important findings for future DAO implementations.
