A safe way to remove objectionable content from the blockchain (now on GitHub)

These goals ensure that the removal process remains optional, ensuring that each node can decide independently whether to engage in the removal of content. Importantly, the approach prioritizes safety, guaranteeing no adverse effects on nodes that opt out of using this feature, while minimizing and mitigating any potential risks for those that do. The initiative emphasizes maintaining full node functionality, enabling nodes that remove content to retain their comprehensive capabilities without dependence on external entities.

A significant aspect of the project involves its retrospective application, allowing for the removal of pre-existing content from the blockchain after the implementation of this solution. This approach is grounded in principles of trustlessness, verifiability, and permissionlessness, with control messages facilitating the data removal process being simple, verifiable statements that anyone can author. Moreover, the project aims to achieve minimal impact on blockchain policy, consensus mechanisms, implementation procedures, usage patterns, and economic factors through a lightweight solution. It also focuses on ensuring the least amount of data is removed, emphasizing aspects such as granularity, associativity, commutability, and idempotence, and facilitating the transferability of sanitized blocks among nodes that share objections to certain content.

The realization of these design goals may present challenges, acknowledging that not all may be achievable simultaneously. Therefore, collaboration and input from the developer community are sought to refine the direction of the project, address unanswered questions, and elaborate on specific considerations and details. The initiator of the project has identified relevant literature to inform the development process, including works on redactable blockchains and their applications, challenges, and future research directions.

Additionally, there have been issues with email communications within the mailing list, particularly concerning the filtering of messages as spam by Google's systems. Despite these obstacles, the project lead remains committed to advancing the initiative, encouraging feedback from previously engaged contributors and indicating an openness to adapt the project based on received insights. This endeavor represents a thoughtful attempt to balance innovation with ethical considerations in blockchain technology management, highlighting a proactive stance towards addressing potentially harmful content stored within decentralized networks.
