Poramin didn't make Zcash (or Zcoin). His former professor at Johns Hopkins, Matthew Green, is an author on both of the papers describing these protocols ( http://zerocoin.org/media/pdf/ZerocoinOakland.pdf and http://zerocash-project.org/media/pdf/zerocash-extended-20140518.pdf ), Poramin Insom is not. The creator of vertcoin (Poramin) implemented zerocoin, first in a closed source scam called Zerovert, and now later in a hugely instamined coin called Zcoin. He is unaffiliated with Zcash (which is also scammy) afaik.
The closed source 'scam' is explained here:
Zerovert was originally intended to be part of Vertcoin's ecosystem however Vertcoin's community were not keen on it. Zerovert's also suffered from very poor performance and had huge scalability issues and therefore the project went silent while we figured out how to solve many of the challenges we faced with Zerovert.
We subsequently managed to fix many scalability issues and these changes have been incorporated into Zcoin. Starting afresh with Zcoin allowed strong investor backing from the likes of Roger Ver and allowed us to dedicate ourselves fully to this project rather than a mere experiment. With investor backing we also could finally make our code open source while still protecting our efforts. These considerations were what prompted us to wipe the slate clean with Zcoin instead of continuing with Zerovert which was never intended to be a serious project.
Instamine and founder's reward are pretty different. Instamines are created upfront while founder's rewards are spread across through the time and are transparent. This ensures that the founders cannot cash out immediately and are incentivized to keep development ongoing at least for the duration of the founder's rewards (4 years in Zcoin).
I spoke with Poramin has not ruled out returning to help out with Vertcoin development once he implements some important fixes with Zcoin. He had thought he had left it in good hands with two devs but when those devs moved on with life (working on startup and studying at MIT) Vertcoin's development was stalled. It wasn't the intention to 'abandon' Vertcoin and he spoke to me about how he wanted to implement EVM for Vert when has has time.
This is getting a bit ridiculous. Even if this Poramin "I spoke with him and he said..." guy comes back Vert still has no plan, and honestly looks like Poramin has a shit reputation in crypto. We're all holding our breathe for a Chinese pump that, as time goes by, keeps looking less and less probable.
Like I said before I have the same interests in this as all of you. I don't get paid for this, no one working on the team does. You guys can complain and speculate all you want, but until you contribute something it really doesn't matter how much you complain. Sure, we could fork and have a nice chunk of the block reward go to the devs so they could get paid for this, or have a "presale" and fund ourselves for a while, but we don't want to do that. And you all wonder why the other team member don't come here .You sound like the bunch that would complain that free ice cream is too cold.
