Thank you for sharing your suggestion, @justmythoughts !
As you noted, this thread ties directly into the recent discussion about canister-controlled neurons and the subsequent motion that was approved in May and is now implemented.
The approved motion states: “This proposal recommends lifting restrictions on canister neuron control in the NNS and monitoring their materiality through newly developed metrics. A threshold is set to initiate mitigation measures if canister-controlled neurons exceed 10% of total voting power. Additional measures to disincentive neuron transfers will be considered and implemented if this threshold is reached, balancing security enhancements with user complexity and implementation effort.”
This directly addresses your concern about the relative value of 8-year canister-controlled neurons compared to 8-year non-canister-controlled neurons due to liquidity differences. If canister-controlled neurons become material, steps will be taken to make holding them less attractive.
Conversely, allowing all neurons to become transferable seems contrary to the spirit of our recent discussion, which set explicit limits on the portion of transferable neurons. As also highlighted by others in this thread, general transferability raises security concerns that need careful consideration.
