The problem of many crypto currencies, including Pascal, is that there is a huge amount of technical mumbo jumbo aimed to tech people and almost nothing written only for simple people who are not interested in the technical stuff. All of the landing pages, including the op, should be directed to the general public with zero information for miners and investors, who should have to do some work clicking links and figuring stuff out rather than the people the coin is made for. It's nice to have good technical ideas but it gets boring when every coin markets to miners and speculators and not to users of currency.
The job of speculators, investors, should be to direct things in a better direction, not just extract money from trends.
Yes, I agree about this, and I'd like to help in fixing this. I don't want to have any credits for this, I just want the documentation to be more in depth. The V2 is lacking details, it does not explain enough, particularly about the checkpointing, and how secure it can stay.
My understanding before reading V2 was according to this image I created:

Basically, on regular interval, you record the hash of the safebox and the safebox number and you can discard all prior blocks. From there, the blockchain dating from this pruning can validate any new account balance in later safebox created after this safebox you recorded.
The V2 WH says the safebox has block header information in every account block sub-structure. This does not tell me what it looks like and how it can prevent an attacker to present you with a fake Safebox that contains an inflated balance for his account. I'm looking forward to see it though.
Regardless whether there is a flaw in their concept or if it is solid, PascalCoin as it is presented in the first white paper - with the safebox - allows pruning of the blockchain on periodic interval. You just need to have the rest of the blockchain past that pruning point, either you hold these blocks yourself (as a miner or a node) or you can get it from somewhere else. From that safebox you secured the hash, you can validate all new transactions leading to new safebox post pruning, hence you can confirm an account really has the Pascal stated in the latest safebox.
BTW, the pruning would be done at least 10 blocks prior to the current block being mine so to allow everyone the time to get all the blocks propagated.
