In October 2009, Finney announced on an essay on the blog Less Wrong that he had been diagnosed with Amyotrophic Lateral Sclerosis (ALS) in August 2009. Prior to his illness, Finney had been an active runner. Finney and his wife Fran Finney raised money for ALS research with the Santa Barbara International Marathon. In March of 2013, Finney posted on a Bitcoin forum that he was essentially paralyzed, but continues to program. He was working on experimental software called bcflick, which uses Trusted Computing to strengthen Bitcoin wallets.
