Gavin Wood, chief technology officer at Ethereum, notes that legitimate businesses are already planning to make use of his technology—for example, to provide a digitally transferable proof of ownership of goldand to power a lottery system.
However, Wood acknowledges it is likely that Ethereum will be used dark bitcoin ways that break the law—and even says that is part of what makes the technology interesting. Just as file sharing found widespread unauthorized use and forced changes in the entertainment and tech industries, illicit activity enabled by Ethereum could change the world, he says.
Regulators like those harrying Uber in many places around the world would be left with nothing to target. Catch dark bitcoin with our coverage of the event. A new prototype gets at how—and why—manufacturers and product designers might benefit from a blockchain.
