An application-specific integrated circuit is a piece of computer hardware designed and manufactured to perform a single function, in this case running the SHA-256 hashing algorithm that secures the Bitcoin network. Modern Bitcoin ASICs are produced by a small number of manufacturers (Bitmain, MicroBT, Canaan) and are several orders of magnitude more efficient than general-purpose hardware. They are the fundamental unit of production in industrial Bitcoin mining.
- In finance terms
- An ASIC is to Bitcoin mining what a drilling rig is to oil and gas, the capital asset that produces the commodity, with an effective economic life of three to five years before it is outcompeted by the next generation of hardware.
- Why it matters to institutions
- ASIC generation and price determine the cost basis of every unit of hashrate an issuer can deliver, and therefore the achievable yield on a hashrate-backed note.
