PISA DISTRIBUTED LEDGER LAB
Welcome to the Pisa Distributed Ledger Laboratory. We are a research group of young (and less young) researchers very passionate about designing, analyzing, and developing distributed ledger-based solutions (mainly blockchain) and distributed social media. The group was founded and is led by Prof. Laura Ricci and is mostly based at the Department of Computer Science, University of Pisa, but it has several worldwide collaborations. Currently, the PISA DLT LAB includes 5 permanent members, 5 Ph.D. students, 2 permanent members working at CNR, and several other collaborations with national and international groups
We invite you to have a look at the topics we cover as well as the full list of collaborations we have.
Give a look to our Thesis Proposals, we publish proposals both for Bachelor Thesis (in italian) and Master Thesis (in english)
