✴ Important Note:
I think you can scale number 1 & 2 (below) thesame way number 3 is scaled. What I find important in scaling them in that manner is that it will become easy to run the *Decentralized spreedsheet and image apps* (see 1 & 2 below) on mobile/light devices like phones.
1. A decentralized spreedsheet for storing & verifying private info

For strong privacy, it's important to always fill the spreedsheet cells in your block/range with many "false" names, addresses, DoB, and other private information. This is to make it very hard for someone who manages to gain unauthorized access to the private info of an individual from knowing the exact private info that belongs to the owner of a block/range.
