Why they matter
Lerner's analysis is the closest thing we have to forensic proof of how Satoshi actually behaved — restrained, careful, and never cashing out. It reframed the search for Satoshi around on-chain evidence.
Profile
Security researcher who in 2013 noticed a unique fingerprint in the ExtraNonce field of the earliest blocks: a single dominant miner ("Patoshi") who deliberately throttled to ~50% of the network, mined an estimated 1.1 million BTC in 2009–2010, and has never spent a single coin.
