The question of digital identity ownership has resurfaced with a vengeance, this time targeting the decentralized social networking protocol, ATProto, the backbone of platforms like Bluesky. While ATProto promises user control and portability, a closer examination reveals a complex web of ownership that might leave many users with less autonomy than they believe.
At the heart of the issue lies the management of ATProto handles, the human-readable identifiers like '@user.bsky.social'. These handles are crucial for navigating the decentralized network, yet their registration and management are not as straightforward as one might assume. While the protocol aims for a censorship-resistant and user-controlled environment, the practicalities of handle registration, particularly the "app passwords" and the reliance on specific applications for initial setup and ongoing management, introduce a point of potential centralisation. If a user loses access to the application through which they registered their handle, or if that application ceases to exist or modifies its terms of service, the user could find their digital identity effectively locked away.
The implications of this are significant. In a decentralized system, the promise is that users truly own their data and identity, free from the dictates of a single corporation. However, if the tools required to access and control one's ATProto identity are themselves controlled by a limited number of entities, that promise is undermined. This raises concerns about the long-term viability and true decentralization of the ATProto ecosystem and similar emerging decentralized social networks. Users might be migrating to these platforms with a false sense of security regarding their digital sovereignty.
As ATProto and Bluesky continue to evolve, how can users ensure they have genuine ownership and control over their decentralized identities, and what steps should developers take to truly empower users?
