Purpose

The workshop aims at creating a fertile ground where to discuss a wide variety of approaches used to study cryptocurrencies, NFTs, token economics, DeFi and smart contracts. In particular, the workshop will stimulate the crosspollination between novel data mining techniques, used to effectively collect, represent, and explore large-scale blockchain datasets, and blockchain economical activity. The end result will be not only a view of the state of the art in this important and growing field but also a common framework to help shape its future development.

Call for Submissions

Satoshi Nakamoto, the pseudonymous creator of Bitcoin, published his famous white paper in the aftermath of the 2008 financial crisis and created the first successful crypto currency. Bitcoin, by proving that it is possible to bring trustless, anonymous transactions to millions of users around the globe, has proven to be an overwhelming success and the starting point of a financial services revolution.

In the years since, several thousand other cryptocurrencies, (Ethereum, Dogecoin, Solana, Cardano, Monero, etc) and crypto tokens (ShibaInu, Basic Attention Token, Tether, Bankcor, USDCoin, Dai) have been launched. Each of these specializes in solving a specific problem, optimizing a given task or in developing a new technology.

Despite their differences all these crypto assets share one point in common: they rely on a public ledger (in the form of a blockchain) that includes all of their transactions in a way that can be publicly extracted and analyzed, providing us with an unprecedented view of an entire economical system.

The goal of this workshop is to bring the attention of the complexity community to this wealth of data, highlight some of the recent developments in this area and the exciting new avenues for research that it opens up.The analysis of this kind of data is intrinsically interdisciplinary, with direct applications to complex networks, data science, computer science, game theory, economics, finance, social science, etc making it highly appealing to Complexity researchers.

We welcome extended 2-page abstract submissions of preprints or previously published manuscripts. Extended abstracts should include one figure, legend and 2-3 relevant references, plus the full paper reference if already available.

Submissions must be written in English and must be submitted electronically through the EasyChair submission page. The review process will be single-blind (i.e., submissions do not need to be anonymized).
