Some other explanation would be useful.
I would think that most correct answer is "d". I've been developing and testing during months. Client App has some bugs, of course, but I think Kernel is Ok.
Idea started at 2013, when I discovered Bitcoin, but I was not a C developer, so I decided to search how to make a new Cryptocoin more easy to use and, of course, writting full source code in Pascal.
The final concept, writted in the White Paper of Pascal Coin, was born 6 months ago.
My intention is to grow with it... If you can, thanks for helping.
Now it's much better, thank you.
I was hoping more in a response of type A or B, because being a different
type of blockchain, it must be checked and tested on the field.
IMHO, A new type of blockchan should be put under stress up to the point of
rupture, with all kinds of generic attack, or specifically targeted on its peculiarities.
Do it on a "purely virtual" currency or in a testcoin allows to make everything without
worries and remorse, or damage to anybody, eventually also changing structure, parameters
or other details of the blockchain along the way.
But if each PascalCoin is already a real and immutable thing, and in the future
will have a concrete value, to avoid losses for the existing users, these tests
and changing are much more difficult to do, if not impossibles, and need a lot of
extra cautions.
Apart this, the project is interesting, and there is a lot of work to do.
I have used the Delphi for a while more then a dozen years ago, so I'm very rusty,
when I have put together a working development environment, I hope I can be helpful,
but having little time, I can not promise anything.
