A project claimed to represent “the first organic neuron Bitcoin miner based on the fly brain” has gone live. Yes, this is a cryptomining project that leans on the fruit fly connectome recently shared by Google. FutureBit, the company behind the Apollo series of ASIC miners, introduced the world to its HashFly this week. However, HashFly is merely a proof of concept for now.

If you open the dedicated HashFly site, you can also participate in this agitation of fruit fly brains in the (vain) hope of a crypto payout. I clicked the 'Mine' button and left it running for an hour, for science, and periodically flipped back to the tab to see the gently rotating fly brain’s neuron traces firing. Looking at the website overlay, one can see the web app represents “2,914 traces firing” within the fly’s brain. It is worth mentioning that this figure is just a small subset of the full 165,122 reconstructed neurons in the MaleCNS v1.0 fruit fly connectome.

We understand that FutureBit’s HashFly focuses on the simulated photoreceptors that would usually sense light in the fly’s eye. These read a block header, and neurons called PPL101 cells light up when a double-SHA-256 target is computed. You can make the target harder and easier by adjusting the ‘zeros’ up and down. Even at maximum difficulty in this proof of concept (level 6), it is far, far easier than finding a real Bitcoin hash, and I saw about 80 blocks checked off in an hour or so.

What’s the point of this proof of concept? According to its designers, it provides some more insight into the potential efficiency of organic computing, or wetware. “Fun fact,” teases FutureBit. “If this could be scaled on real organic neurons, it would hash at ~ 1 watt per terahash... 10x the efficiency of the best silicon 3nm ASICs!” These guesstimates are based on “total power used by the fruit fly, and assuming all neurons could be used to hash Bitcoin functions and continually keep firing,” says the Bitcoin mining hardware maker in a follow-up tweet.

Those who find this experiment interesting may be happy to hear that the HashFly demo will be scaled up to its logical conclusion. “We are working on simulating all neurons in the dataset with the sha256 hash function and will publish all our findings,” says FutureBit. It certainly needs scaling up if my HashFly web performance of ~100 kH/s is typical. Compare that to the firm’s 5-inch cube Apollo III, which is claimed to deliver “up to 18 TH/s of Hashpower.”

We’ve seen a few other fly brain connectome mapping-inspired projects from the fevered minds active on social media over the last week or so. Almost immediately after Google announced it had published the complete brain and central nervous system of an adult male fruit fly, we saw people seeing if it could play Doom, indulge in financial day trading, and many more frivolous pursuits.

There’s even a rival cryptomining scheme dubbed the FlyMiner. Visiting this portal, you can see a fruit fly connectome that has been put under the control of an ASIC miner. Visiting that site will also be limited to a brain-nourishing, not money-spinning, activity, as FlyMiner admittedly has “almost zero chance” of mining success.

There is increasing evidence that Mexican drug cartels are diversifying into cryptocurrency mining and are using crypto platforms to diversify their income and, at the same time, launder their ill-gotten gains and fund other illegal activities. Reuters reports that local Mexican police uncovered a clandestine cryptocurrency farm in Tlaola, a town located in the leafy mountains of Puebla's Sierra Norte region. They found 300 GPUs, electricity infrastructure, and satellite equipment. The electricity-hungry operation likely drew power by secretly tapping into the grid at Presa de Necaxa, a nearby hydroelectric dam.

While this latest hidden facility found by police may seem small, Reuters notes it is the fourth such crypto farm Mexican authorities have uncovered in this region since early last year. According to a Mexico-based security analyst, the crypto farms discovered show that the cartels are increasingly sophisticated in their operations. In the latest bust, the Mexican federal authorities, the Navy, and state police seized around 300 GPUs, 80 medium-voltage terminations, a transformer, and eight satellite antennas.

It might not be surprising to hear about the Mexican cartels being tied up in crypto. Blockchain analytics firm Chainalysis, as cited by Reuters, reckons illicit crypto transactions grew from $59 billion in 2024 to $154 billion last year. The firm links the surge recorded to sanctions evasion involving governments. However, in South America, cartels are increasingly interested in using this channel to launder money. The mining operations are also integrated into the scheme, as stealing electricity is easy for organized crime. Mainstream consumer GPU mining ended in H2 2022, flooding the market with used graphics cards.

The source report doesn’t say how authorities found the crypto farm. Perhaps locals in this remote area of Puebla alerted authorities to the operation. Two folks from neighboring communities told Reuters that they could hear the crypto farm noise (transformers, cooling) from a kilometer away (0.6 miles), and the place was apparently a mere 2 km (1.2 miles) from the nearest village. The other three recently uncovered crypto farms were also near the same HEP dam, it is noted. Tlaola is a small community with around 20,000 inhabitants, so the noise levels and power consumption of crypto farms are very perceptible even if the cartels try to hide them deep in the mountains.

Remote communities, such as Tlaola, are popular locations for clandestine crypto farms because the electricity is cheap and most of them are under the protection of the cartels. For example, the Cartel Jalisco Nueva Generación (CJNG) and its armed branch, La Barredora, have the strongest presence in Puebla.

According to SILIKN, a Mexican cybersecurity firm, the use of cryptomining to launder illegal money rose by at least 55.8% last year in México. Drug cartels such as the Cartel de Sinaloa and the CJNG have set up crypto farms to mine Bitcoin (BTC), Monero (XMR), and Tether (USDT).

Similarly remote, illicit cryptomining facilities exist around the world, with Reuters recalling news of raids in Brazil, the U.S., and Thailand. Do you think there’s one near you? Please call the local police and liberate those stressed GPUs. Meanwhile, analysts expect crypto-related crime will reach new heights in the coming years.
