Where as in biological self-custody, there are physical attributes in your creation, digital self-custody is an arbitrary abstraction. Essentially you are picking a random point, known as a private key, in the digital space and defining that as your own. In most digital self-custody systems the digital space is so large, that the number of points within it is larger than the number atoms in the entire universe. Thereby when you pick this private key, rest assured it is highly unlikely, if not impossible that another entitity chooses that same private key. An important point to note is that in both Digital Self-Custody and Biological Self-Custody the construct on which you have self-custody is entirely random. In Biological Self-Custody all of your physical attributes are defined by your DNA which is a random creation and as well in Digital Self-Custody as we have mentioned you are choosing a random private key in a large digital space. The next section will explain specifically the mechanics of this digital space and the mechanics of this private key.
