Developed by Max Dovey, an artist and researcher at the Institute of Network Cultures, Breath repurposes a medical tool called a spirometer that measures how much air is inhaled and exhaled by your lungs. This data is then fed to a small computer mining on the Monero blockchain.
While a user’s breath doesn’t actually power the computer, it does determine the computer’s hashrate, which ultimately determines how much Monero the computer can mine. According to Breath’s website, 1 puff per second equates to the computer performing 1,000 hashing operations per second. This may sound like a lot, but it’s just a drop in the ocean of the Monero network’s total hashrate: Around 500 million hashes per second.
