FutureBit's Browser-Based Simulation HashFly Models Bitcoin Mining Process

FutureBit's HashFly is a browser-based proof of concept that simulates a portion of the Bitcoin mining process. Introduced on September 13, 2026, it uses a simplified target and runs on a simulated fruit-fly connectome. This demonstration models part of the mining process but does not mine on Bitcoin's live network.

HashFly uses a dataset called MaleCNS v1.0, which contains 2,914 reconstructed traces from a broader connectome with 165,122 neurons. The demonstration only uses a portion of this graph, specifically 25 million synapses.

The simulated mining sequence works as follows: the block header is read by R1, R6 photoreceptors, and SHA-256d (a double application of the SHA-256 hashing function) is checked against a simplified threshold. If the hash falls below this threshold, two PPL101 cells respond in the simulation.

In one reported browser run, about 80 blocks were checked in roughly an hour, with a hash rate of about 100 kH/s. This figure describes activity in the demonstration and is not a count of Bitcoin-network blocks or evidence of a payout. FutureBit estimates that if scaled to real organic neurons, HashFly could potentially reach about 1 W/TH (watt per terahash) and be ten times as efficient as the best silicon 3 nm ASICs.
