Blockchain seems to make possible the removal of any central authority for allowing payments by a digital coin, solving the risk of double-spending.                                                                                                                                                    In addition, from the publication of the white paper ‘Bitcoin: A peer-to-peer electronic cash system.’, many cryptocurrencies (or cryptos) have been launched, forming a rich and complex market.

In this scenario, many challenges show up, like those related to the energy consumption for running a Blockchain.

Here, modern Complexity Science is probably the right domain for analysing these emerging technologies and the related phenomena at different levels, e.g. economic, social, environmental, and many others.

Therefore, during this workshop, we would like to discuss questions as: What is the impact of Blockchain on our society? How can Blockchain shape online services in the future? How are cryptos affecting markets and payment methods?

To this end, we aim at gathering researchers from academia and professionals from the industry interested in this field.
