As long as it is a niche-experiment that is fine.
However, if we want to talk about mass adoption of ZEIT and being any alternative to fiat money, we have to reduce these requirements considerably.
I can't imagine 7 billion people with at least 1GB of RAM memory to do their everyday life, buy groceries for example. Could you?
Also using the argument that we are 'as bad as the other two competitors' is not the most fortunate, in my opinion. The goal should be to be at the other end of the curve, right? Don't understand me wrong, I am trying to bring some constructive criticism in here.
Moreover, it looks to me like the problem of massive blockchain when choosing 30s blocktime has been already seen at the time of designing ZEIT. that is why we have PoS age of 20 days, in order not to have to handle even more data.
When we hit mass adoption , there will need to be a running Genesis Block, that drops off the old block chain at a timed interval, it is the only permanent solution.
Criticism is fine, but it is already something that is being watched. And the current fix like a chain swap can cause other issues which are just not worth the effort yet.
The comparison was just to show more coins than ZEIT use a gig of ram, and that eventually all coins will have those requirements, you need to recognize Zeit is still very young, and we have one Amazing Dev Rent_A_Ray, but keyword
one , something like a running genesis block will take a team of Devs. Not even BTC has achieved a running genesis block and they have the most devs and funding.
As far , as the 7 billion go , odds are a large majority of them will use online web wallets instead of running it themselves, and those web wallet providers will also provide a type of Zeit card services, so those users can buy groceries by swiping a card.
Moreover, it looks to me like the problem of massive blockchain when choosing 30s blocktime has been already seen at the time of designing ZEIT. that is why we have PoS age of 20 days, in order not to have to handle even more data. Actually , I think they were unaware of the issue, which is why now you see a lot of new PoS coins with block times 2½ or 5 minutes trying to avoid large blockchains.
But the trade off of their higher block time is a smaller blockchain but a reduced ability to carry transactions once fully used.
Actually the 20 day age is to make sure the rich don't monopolize the minting process and give everyone a fair chance to stake.
Those coins with only a day or 2 age requirement are monopolized by the large stakeholder blocking out the little guy.
And that monopolized by the large stakeholder issue will also be a problem for the larger block times as they have a limited # of chances to stake.
