A full node in the Bitcoin network -- the node that stores and processes all the data in all blocks -- took up 15GB of disk space in April 2014, and is growing by more than 1GB every month.

And now we have 500GB+ Bitcoin blockchain.

User unique account
In user uniqueness, each user generates a unique code through face recognition

Just like on your previous thread, you doesn't seem to mention about how to prevent people from stealing other people image face, AI-generated face and other potential exploit.

Blockchain and computing
The user-unique blockchain is completely different from the Ethereum bitcoin blockchain,
Bitcoin is extremely inefficient because it needs to store the entire state of each block. The reason is that the state is stored in the tree structure and only a small portion of the tree needs to be changed after each block is added. So in general, most of the tree should be the same between two adjacent blocks, so data can be stored once and referenced twice with Pointers (that is, hashes of subtrees).

Bitcoin doesn't store entire on block. Block is used to store transaction, while current state (as in UTXO) is implemented and stored differently by each full node software.

With the length of your write up, most users won't be interested in reading. You could have at least summarized it a bit and bring out the most important points.

I agree. In addition, lack of proper text formatting (such as bigger font/bold for heading) and separation between section makes it hard to read.
