Notahash creates music from the pulse of blockchain technology, using hash values as inspiration. The Notahash method transforms the silent hash values of Bitcoin and Ethereum blockchains to symbolize historically significant addresses, wallets, and transactions into a symphony of sound. Taking a 16-digit hash value, we divide our sound scale into numerical values from 1 to 9 and letter values from A to F, known to all classical and jazz musicians, and create an equation for harmony.
