From the article: "Bitcoin-NG addresses the scalability bottleneck by enabling the Bitcoin network to achieve the highest throughput allowed by the network conditions. Paradoxically, not only does it improve transaction throughput, it also reduces transaction latencies -- it is possible to get an initial transaction confirmation in seconds rather than in minutes. And it does so without changing Bitcoin’s open architecture and trust model."

@stanga as you are one of the authors, could you give us a tl;dr as to how this is possible?
