About the Workshop
In recent years, blockchain-based networks such as Bitcoin emerged from a purely underground internet cypherpunk movement to become a mainstream reality, attracting the interest of relevant academia and industry actors. Nevertheless, the peculiar convergence of concepts belonging to heterogeneous fields such as economy, computer science, and mathematics still makes it often difficult to capture an organic vision of the potentially revolutionary impact of such technologies. This workshop tackles such complexity by introducing a technical but still intuitive overview of the main concepts behind a blockchain, from the cryptographic foundations to the game-theory-related aspects that make it possible. In the second part of the workshop, concrete examples will be shown on the Bitcoin blockchain, including hands-on sessions regarding transactions, block explorers, and keys management. Finally, the last part of the workshop will discuss the most challenging problems regarding the scalability for a mass adoption of blockchains. After providing a background on Bitcoin layer 2 (The Lightning Network), a summary of the arising related research problems will be presented, including routing, scheduling, rebalancing, and topology analysis.
