Another challenge with neuron transfer: wouldn’t this very much complicate liquid democracy?
Once neurons start following a broader variety of other neurons, wouldn’t neuron transfer make it much more of a challenge to ensure that you’re still following who you want to, given that the neuron you’re following may at any arbitrary time be sold to another principal? Many of the guarantees of liquid democracy would seem to break down.
This could also very much compound the security risks here.
Malicious actors technically need only a significant proportion of the liquid voting power on the IC at a given moment to determine NNS outcomes. Some neurons can have small ICP stakes, but a ton of voting power from followers and their followers. So it could be relatively very cheap to buy at-least-momentary control of the IC if neurons can be transferred - nothing remotely close to the cost of “50% of the ICP + 1 vote,” as is more commonly discussed.
Unless these challenges can be addressed, supporting neuron transfer looks prohibitively risky.
