Exploring Extended Relative Timelocks

It touches upon the challenges of making policy scripts or miniscripts more user-friendly, especially when it comes to validating these on signing devices by average users. The email further delves into the technicalities of implementing time-based conditions in cryptocurrency transactions, such as rolling timelocks which necessitate creating new descriptors every time a timelock is reset. This process involves making proper backups and registering or validating policies on signing devices, pointing towards the intricacies involved in managing timelocks and the potential for simplifying these mechanisms.

The conversation also explores the idea of extending relative timelock limits to accommodate longer periods, discussing the benefits and drawbacks of such an extension. It debates the practicality of setting timelocks up to ~10 years, considering both the current limitations and the potential use cases that could benefit from extended timelocks. The discussion acknowledges the risks associated with locking funds over extended periods, especially considering the unpredictable nature of technological advancements like quantum computing. However, it suggests that the current max limit for relative timelocks is too low, proposing a potential workaround through the modification of certain parameters, such as using bit 21 with 8-block units to extend the duration of timelocks effectively.

Furthermore, the dialogue includes technical considerations regarding the representation of relative timelocks, highlighting the issue of redundancy and the confusion that might arise from having multiple methods to represent certain values. It calls for a standardized approach to mitigate these risks, emphasizing the need for clarity and efficiency in programming related to timelocks.

The email also addresses a broader perspective on cryptocurrency mechanisms, contrasting traditional coin locking schemes with those employed by Liana, where coins are not explicitly locked but rather become inaccessible under certain conditions. This nuanced understanding underscores the importance of clear conditions for coin access and the implications of failing to meet these conditions.

In conclusion, the discussion encapsulates a thoughtful examination of timelock management in blockchain systems, advocating for simplification, clarity, and the potential expansion of timelock durations. It underscores the importance of balancing technical feasibility with user needs and security considerations, aiming to foster a more accessible and robust framework for managing timelocks in cryptocurrency transactions.
