Blockchain Piano is a digital art installation that continuously swaps between cryptocurrency and music. It turns real-time market price into a musical note; when you press a key, you are also buying cryptocurrency. It uses music to disrupt the market, and market volatility becomes part of the melody—turning investment behavior into a performance. This work was created for Digital Art Fair Asia and an adaptation of the work "The Sound of Market" from 14 years ago with added interactive elements.
