A new Bitcoin-inspired technology that some investors believe will be much more useful and powerful may be set to unlock bitcoindark profile new wave of criminal innovation.
That technology is known as smart contracts—small computer programs that can do things like execute financial trades bitcoindark profile notarize documents in a legal agreement. Intended to take the place of third-party human bitcoindark profile such as lawyers, which are required in many deals and agreements, they bitcoindark profile verify information and hold or use funds using similar cryptography to that which underpins Bitcoin.
Ari Juelsa cryptographer and professor at the Jacobs Technion-Cornell Institute at Cornell Tech, believes they will also be useful for illegal activity—and, with two collaborators, he has demonstrated how. One example is a contract offering a cryptocurrency reward for hacking a particular website.
It will release them only to someone who provides proof bitcoindark profile having carried out the job, in the form of a cryptographically verifiable string added to the defaced site. Contracts with a similar design could be used to commission many kinds of crime, say the researchers. Most provocatively, they outline a version designed to arrange the assassination of a public figure.
A person wishing to claim the bounty would have to send information such as the time and place of the killing in advance. The bitcoindark profile would pay out after verifying that those details had appeared in several trusted news sources, such as news wires.
A similar approach could be used for lesser physical crimes, such as high-profile vandalism. He and his coauthors say they are trying to publicize the potential for such activity to get technologists and policy makers thinking about how to make sure the positives of smart contracts outweigh the negatives. Nicolas Christinan assistant professor at Carnegie Mellon University who has studied criminal uses of Bitcoin, agrees there is potential for smart contracts to be embraced by the underground.
Indeed, some criminals have made significant gains from Bitcoin. The Perfect Internet Crime? And Christin published a paper this week tracing the evolution of online marketplaces for contraband that have been partly bitcoindark profile by Bitcoin. It shows that although the most notorious, Silk Road, was taken down by U.
Still, Christin notes that the scale of criminal activity made possible by Bitcoin today, and perhaps by smart contracts bitcoindark profile the future, is tiny compared with more traditional, cash-based physical crimes. Smart contracts are also more complex to use than Bitcoin transactions, he adds. Writing a smart contract or properly understanding the terms of one takes specialized programming skills.
Gavin Wood, chief technology officer at Ethereum, notes that legitimate businesses are bitcoindark profile planning to make use of his bitcoindark profile 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 in ways that break the law—and even says that is part of what makes the technology interesting.
Just as file bitcoindark profile found widespread unauthorized use and forced changes in the entertainment and tech industries, illicit activity enabled bitcoindark profile Ethereum could change the world, he says.
Regulators like those harrying Uber in bitcoindark profile places around the world would be left with nothing to target. Catch up with our coverage of the event. A new prototype bitcoindark profile at how—and why—manufacturers and product designers might benefit from a blockchain.
