Thanks you very much. Could you share some details about the reasons for such opinion? Trying to dive into that, I haven't found any serious solid claims for that. If that is a subject for another question, I will create one.

@Polyakoff: There is a question here, but the answers aren't too great: [What are the downsides of proof of stake?](http://bitcoin.stackexchange.com/q/25743/5406). Essentially, it doesn't guarantee to come to consensus when people are trying to attack it, because no one has to commit to mining only on one branch of a blockchain fork. You could mine on every branch, because it doesn't cost you anything to mine.

<p>Specifically, I'm interested in the thick clients with Simplified Payment Verification. Haven't found these so far, do they even exist? Why are the POS mobile wallets such poorly distributed comparatively to the POW coins?</p>

<p>Thanks in advance.</p>

Are there any POS coin open source mobile wallets implementations?

Specifically, I'm interested in the thick clients with Simplified Payment Verification. Haven't found these so far, do they even exist? Why are the POS mobile wallets such poorly distributed comparatively to the POW coins?

Thanks in advance.
