A co-founder of Tornado Cash was convicted of conspiring to run an unlicensed money-transfer operation that laundered more than $1 billion through the crypto platform in a closely watched case with sweeping implications for open-source development and blockchain privacy.

A U.S. jury deadlocked on Wednesday on money laundering and sanctions evasion charges against the founder of Tornado Cash, a firm that makes cryptocurrency transactions harder to track. The jury in Manhattan federal court could not reach a verdict on charges Roman Storm conspired to launder the proceeds of hacks,

A jury could not agree on whether Storm helped launder more than $1B in dirty crypto, including for North Korea. They convicted on one lesser count.
