Using electrophysiology in fungi for bio-entropic encrypted messaging.

Mycë is a bio-hybrid computing system that harnesses living mycelium networks to generate truly random numbers for cryptographic applications. Just as Cloudflare uses their iconic lava lamp wall as a physical entropy source for encryption, Mycë captures and analyzes the electrical signals naturally produced by mushrooms as they grow, mature, and respond to environmental stimuli. Through controlled experiments, we measured microvolts across mycelium networks, stems, and caps at various growth stages. We used different watering schedules and light stimulation to induce varied responses. These biological signals are processed to generate cryptographic seeds that are inherently unpredictable. This addresses one of the most fundamental challenges in data security: predictable seeds create vulnerable encryption keys. To demonstrate this technology in practice, we developed an encrypted peer-to-peer messaging application similar to Telegram. Mycelium-generated keys secure user communications in this application. Mycë proves that biological systems can achieve randomness comparable to advanced digital random number generators. More importantly, it proposes a paradigm shift in computing by moving away from technologies that push nature to its limits. Instead, we can build symbiotic systems that integrate with and support natural processes. This approach points toward a more sustainable, resilient, and ethically grounded future for computing infrastructure.
