Short biography

Nicolò Vallarano fields of research range between the statistical mechanics of networks and distributed ledger technologies. His PhD thesis included an application of an improved version of the ERGM configuration model to the network of Bitcoin Users Transactions.

At the moment he collaborates with professor Claudio Tessone modeling consensus protocols other than the classic Bitcoin Proof-of-work.

As part of his research activity he collaborates to the Blockchain Observatory in the study and classification of cryptocurrencies economic state.
