I have looked at the code and Albert did an amazing job. I just don't understand why there is code that's not being used. I could not debug it.
Albert has done a great job to make PascalCoin from scratch. But I have to admit that I find it hard to read his code

Some of the code have been changed and some part have been rewritten several times. Old features have been abandoned. This makes it even harder to read. But still it is a great job.
