{"abstract":[{"text":"Payment channel networks (PCNs) are a promising solution to the scalability problem of cryptocurrencies. Any two users connected by a payment channel in the network can theoretically send an unbounded number of instant, costless transactions between them. Users who are not directly connected can also transact with each other in a multi-hop fashion. In this work, we study the incentive structure behind the creation of payment channel networks, particularly from the point of view of a single user that wants to join the network. We define a utility function for a new user in terms of expected revenue, expected fees, and the cost of creating channels, and then provide constant factor approximation algorithms that optimise the utility function given a certain budget. Additionally, we take a step back from a single user to the whole network and examine the parameter spaces under which simple graph topologies form a Nash equilibrium.","lang":"eng"}],"oa":1,"year":"2023","author":[{"first_name":"Zeta","last_name":"Avarikioti","full_name":"Avarikioti, Zeta"},{"full_name":"Lizurej, Tomasz","first_name":"Tomasz","last_name":"Lizurej"},{"full_name":"Michalak, Tomasz","first_name":"Tomasz","last_name":"Michalak"},{"full_name":"Yeo, Michelle X","id":"2D82B818-F248-11E8-B48F-1D18A9856A87","first_name":"Michelle X","last_name":"Yeo"}],"day":"11","language":[{"iso":"eng"}],"main_file_link":[{"url":"https://doi.org/10.48550/arXiv.2306.16006","open_access":"1"}],"page":"603-613","citation":{"ista":"Avarikioti Z, Lizurej T, Michalak T, Yeo MX. 2023.
