# ASIC Miners (SHA-256)

## Definition

Application-Specific Integrated Circuits — highly specialized computers designed exclusively to run the **SHA-256** hashing algorithm to mine Bitcoin.

## The hardware lineage

[[entity-asher-genoot]] traces how mining hardware evolved as the network grew and cryptographic puzzles became harder:

1. **CPU era.** Individuals could mine on standard PCs.
2. **GPU era.** Miners shifted to graphics cards for higher hash throughput.
3. **ASIC era (today).** The network is dominated by ASICs — single-purpose chips that do *only* SHA-256.

## What ASICs are and aren't

- They are incapable of running standard software, rendering graphics, or performing AI workloads.
- Because they are hyper-optimized for one function, they are extremely efficient at hashing.
- They require **massive electricity** and advanced cooling (including **liquid cooling**) when operated at scale in industrial data centers.

## Why this matters for the corporate model

ASICs are *expensive* and they *depreciate quickly* as newer generations arrive. This is the root cause of the dilution problem in traditional public miners (see [[contrarian-mining-stock-dilution]] and [[prereq-stock-dilution]]): companies constantly issue new equity to fund the next ASIC refresh, and per-share Bitcoin exposure shrinks.

The [[concept-bitcoin-accumulator-model]] sidesteps this by using at-cost infrastructure from [[entity-hut-8]] rather than owning the data-center buildout outright.

It is also relevant to [[question-energy-competition]]: ASIC operators compete with AI data centers for cheap electricity, and the question of whether mining can keep accessing low-cost power as AI demand scales is genuinely open.
