Scaling blockchains without giving up decentralization and security
Gianmaria Del Monte, Diego Pennino, Maurizio Pizzonia · 2020
Public blockchains should be able to scale with respect to the number of nodes and to the transactions workload. The blockchain scalability trilemma has been informally conjectured. This is related to scalability, security and decentralization, stating that any improvement in one of these aspects should negatively impact on at least one of the other two. In fact, despite the large research and experimental effort, all known approaches turn out to be tradeoffs.
