Decentralized Finance (DeFi) is a new financial paradigm that leverages distributed ledger technologies to offer services such as lending, investing, or exchanging cryptoassets without relying on traditional centralized intermediaries. A range of DeFi protocols implements these services as a suite of smart contracts, i.e., software programs that en...
The rapid growth of the Ethereum ecosystem since 2020 has been driven by the proliferation of several DeFi protocols [10], which are application-layer programs that provide Decentralized Finance (DeFi) services [14, 16] such as the exchange of cryptoassets on decentralized exchanges (DEXs) [2, 7, 15], their lending and borrowing [1, 4, 8], or the c...
We present a measurement study on compositions of Decentralized Finance (DeFi) protocols, which aim to disrupt traditional finance and offer services on top of distributed ledgers, such as Ethereum. Understanding DeFi compositions is of great importance, as they may impact the development of ecosystem interoperability, are increasingly integrated w...
We present the first study on compositions of Decentralized Finance (DeFi) protocols, which aim to disrupt traditional finance and offer financial services on top of the distributed ledgers, such as the Ethereum. Starting from a ground-truth of 23 DeFi protocols and 10,663,881 associated accounts, we study the interactions of DeFi protocols and ass...
In recent years extensive research has been conducted on the development of different models that enable energy trading between prosumers and consumers due to expected high integration of distributed energy resources. Some of the most researched mechanisms include Peer-to-Peer energy trading, Community Self-Consumption and Transactive Energy Models...
We mine the leaked history of trades on Mt. Gox, the dominant Bitcoin exchange from 2011 to early 2014, to detect the triangular arbitrage activity conducted within the platform. The availability of user identifiers per trade allows us to focus on the historical record of 440 investors, detected as arbitrageurs, and consequently to describe their t...

We mine the leaked history of trades on Mt. Gox, the dominant Bitcoin exchange from 2011 to early 2014, with the aim of identifying investors who performed two-point arbitrage between Mt. Gox and three other cryptocurrency exchanges (BTC-e, Bitstamp, Bitfinex). Most importantly, the availability of user identifiers per trade allows us to reconstruc...
The functioning of the cryptocurrency Bitcoin relies on the open availability of the entire history of its transactions. This makes it a particularly interesting socio-economic system to analyse from the point of view of network science. Here we analyse the evolution of the network of Bitcoin transactions between users. We achieve this by using the...
