# Bitcoin Mempool vs Black Hole Accretion Disk

In this short mathematical paper, we will discuss the comparison between the Bitcoin mempool and a black hole accretion disk, as well as the Bekenstein bound and observer's bias.

### Bitcoin Mempool vs Black Hole Accretion Disk
Although the Bitcoin mempool and black hole accretion disk operate in different realms, we can draw a parallel between them using information theory. Let us denote the information density of a system by $I$.

I = \frac{S}{V}

Where $S$ is the system's entropy and $V$ its volume. In the case of the Bitcoin mempool, it can be considered as a collection of unconfirmed transactions, while the accretion disk consists of matter orbiting a black hole.

### Bekenstein Bound and Observer's Bias
The Bekenstein bound is a limit on the entropy $S$ of a physical system based on its energy $E$, radius $R$, and the reduced Planck constant $\hbar$.

S \leq \frac{2\pi RE}{\hbar c}

Observer's bias can be accounted for by introducing a correction factor $f$:

S_\text{corrected} = fS

The corrected entropy allows us to account for the observer's bias and better understand the system's behavior. In summary, while the Bitcoin mempool and a black hole accretion disk are distinct, we can use information theory to draw parallels and investigate their properties with respect to the Bekenstein bound and observer's bias.
