Awesome news - “Ouroboros Praos is the latest version of the Ouroboros protocol, which was released in February 2017. The protocol is the first proof of stake blockchain to provide security against adaptive attackers and is fit to scale for truly widespread use. Ouroboros Praos offers the same security guarantees as Bitcoin in that it can withstand attacks from stronger adversaries in harsh network conditions. No other proof of stake protocol can provably offer this level of security guarantee under these conditions.”
