Bitcoin mining has spent more than a decade becoming increasingly specialized: CPUs gave way to GPUs, FPGAs and eventually purpose-built SHA-256 ASICs.

FutureBit is now experimenting in almost the opposite direction.

Its HashFly proof of concept uses a simulation based on a fruit-fly connectome—a digital map of neural connections—to explore whether neuron-like computation can be used in a Bitcoin hashing experiment. The browser demonstration activates 2,914 simulated neural traces while performing simplified hashing work.

There is an important qualification: HashFly is not currently an alternative to a Bitcoin ASIC. The demonstration executes on conventional computer hardware and operates at roughly the kilohash-per-second scale. Modern Bitcoin ASICs operate in the terahash-per-second range, many millions of times faster.

From Connectomes to Computation

The underlying scientific development is real and considerably larger than the mining demonstration. Researchers have reconstructed fruit-fly nervous systems containing well over 100,000 neurons and tens of millions of synaptic connections, giving scientists detailed maps for studying how biological neural systems process information.

HashFly asks a very different question: could structures inspired by biological wiring eventually perform computational work relevant to proof-of-work hashing? For now, the answer is experimental.

The 1 W/TH Claim Needs a Large Asterisk

FutureBit has suggested that a hypothetical system using actual organic neurons could potentially approach roughly 1 watt per terahash. That number should not be treated as measured mining efficiency. It is a projection based on assumptions about biological energy consumption and the possibility of dedicating neurons continuously to hashing. FutureBit has not demonstrated a physical neuron-based miner operating at 1 J/TH, nor has HashFly shown performance remotely comparable with modern ASIC silicon.

Today’s Announced ASIC Frontier: 8.9 J/TH

The comparison is especially interesting because conventional mining silicon continues to improve. Bitmain’s newly announced Antminer S23 XP Hyd. is manufacturer-rated at 600 TH/s, 5,340 W and 8.9 J/TH. Announced at WDMS Global Hong Kong on August 28, 2026, it is a hydro-cooled futures/presale product with shipping expected from November 2026.

That distinction matters: 8.9 J/TH is Bitmain’s announced specification for the S23 XP Hyd., not yet a broad set of independently measured field results from deployed units. Still, it provides a much more current reference point than the previous 9.5 J/TH S23 Hyd. generation.

FutureBit’s speculative ~1 J/TH organic-neuron concept would therefore imply an enormous additional efficiency jump even compared with an announced sub-9 J/TH ASIC. HashFly has not demonstrated that jump; it illustrates a research direction.

The distinction is particularly relevant to BitcoinVersus.tech’s ongoing hardware research. BitcoinVersus previously examined the Bitmain S23 Hyd 3U, while our Bitcoin Mining Singularity research explores how mining hardware could progress toward much lower joules-per-terahash levels over time.

Neuromorphic processors, three-dimensional architectures, photonics and other unconventional computing systems could eventually influence specialized computation. But Bitcoin mining provides an unusually unforgiving benchmark: a new architecture does not merely need to compute SHA-256. It has to perform enormous quantities of double-SHA-256 operations reliably, continuously and economically while competing against ASICs engineered for essentially one job.

HashFly has not crossed that bar. What it has done is create a strange but technically interesting experiment: taking a biological wiring diagram, turning part of it into a computational simulation and asking what happens when the architecture meets proof of work.

For Bitcoin hardware research, sometimes the useful result is not a faster miner. It is discovering another direction computation might eventually take.
