Ethereum could soon launch its first Casper testnet. Ethereum developers are looking to use code for their experimental Casper proof-of-stake protocol as the basis for a new test network. During a core developer meeting today, ethereum founder Vitalik Buterin said that not only is Casper ready to be tested, but that it could provide a security boost when testing code across clients. It's a prospect that could come as a relief to developers, particularly those working on projects that must interface with the network's varied client offerings.
