These are fraudulent investments which repay users with the funds invested by new users that join the scheme, and implode when it is no longer possible to find new investments. The Bitcoin dePonzifier is a classifier of Ponzi schemes based on supervised learning algorithms.

Blockchain Analytics

Modern cryptocurrencies exploit decentralised blockchains to record a public and unalterable history of transactions. Besides transactions, further metadata is stored for different, and often undisclosed, purposes. Metadata is mostly generated by protocols and smart contracts, i.e. programs whose correct execution is automatically enforced without relying on a trusted authority. This project investigates tools and techniques for analysing blockchains, their metadata, and smart contracts, focussing on Bitcoin and Ethereum...

Blockchain for social good

We carry out a quantitative research on blockchain technologies for social good, based on the analysis of more than one hundred projects. Focussing on measurable and objective aspects, we try to answer various relevant questions: which features of blockchains are most commonly used? Do projects have success in fund raising? Are they making appropriate choices on the blockchain architecture? How many projects are released to the public, and how many are eventually abandoned?
