This is why I added f != 0 (mod L) requirement to section 3.3. And there's an easy way to ensure f != 0 for commitments without additional data. I'm going to cover this in the next paper update.
Perfect, thank you very much !
We at Zano don't favor cold staking much because we believe it creates incentives that favor centralization.
Mhh, I don't know if we are talking about the same implementation of cold staking : I was referring to the ability to stake with funds secured in a Hardware Wallet. So, even if someone succeed to compromise my computer, my funds would still be safe. This is imho an important security feature. I share your concerns regarding an implementation that allows the creation of "Staking Pools", I also do not like this type of centralization and this is not what I was referring to. So my exact question would rather be, is staking with funds secured in a hardware wallet something that Zano could do in the future ?
Hi, thank you for the question.
From that perspective it is possible theoretically, but only if there will be a hardware wallet that will be able to provide necessary information for staking algo (such as key images), and also it should be capable to perform signing of generated blocks without user interaction(which is not considered as a weakness, since it can't lead to unauthorised transfer of coins if properly implemented).
