I had this conversation several time with people having concern regarding NFTs: you can just copy paste an image and say it belongs to you.
Yes, you can, but from the machine point of view, this image does not belong to you

The problem is that people are fooled by their senses, so we need software programs to reflect the [[Blockchain]] point of view, for example, uploading a profile picture to Twitter should require an interaction with the blockchain to check it's your.
## Blockchain & Pointers
In computer [[Programming|programming]], some variables are internally stored in an address in your computer memory
| Adress | Value | Variable name | |
| -------- | ----- | ------------- | --- |
| 0x897876 | 42 | foo | |
| 0x885433 | 42 | bar | |
`foo` and `bar` have the same value, but it's still a different address.
## Equality or identity
If Bob is on the earth and is suddenly cloned (using some new tech) exactly, particles per particles, on the moon, is Bob2 equal to Bob1?
| Adress | Value | Variable name |
| ------ | ----------------------------------------------------------------------------------------------------------------- | ------------- |
| Earth | Carbon-based particles forming a bipedal life form descended from an ape by a process of [[Evolution\|evolution]] | Bob1 |
| Moon | Same | Bob2 |
