How much memory is needed for a regular PC run ethereum to get POS rewards? and what is the percentage of POS? anything finalized yet?
I read Ethereum POS was like a new lottery based system, which did not require PC hardware e.g. may be web-based options.
Also, nowadays you get POS mining pools, which mean you do POS via a proxy pool.
Here is a technical explanation of POS at Serenity hardfork
https://blog.ethereum.org/2016/03/05/serenity-poc2/Generally, POS works on bigger coins, when you can get towards 0% inflation. For example PPC, has a ongoing POS at 1% simultaneously as the POW.
However, a mix of POW and POS structure can operate as disincentive to new investors or miners.
POS works best, when done as an investor capture system, e.g. when a crypto coin get a huge enough investor base or becomes very famous - a POS between 0.01%-1% reward (in theory) should be sufficient to retain investors and interests.
Do note: if the crypto coin gets a tiny investor base or is unknown the POS will be diluted by a developer with ridiculous POS rates of 5%-1000% in an attempt to retain investors and interest.
The latter does not apply to Ethereum
