Faktory ovlivňující používání Lightning Network mezi uživateli Bitcoinu

This bachelor's thesis examines factors associated with the intention to use the Lightning Network and with its self-reported frequency of use among Bitcoin users. The aim of the thesis is to identify key predictors of second-layer adoption within the Czech and surrounding Bitcoin community. The research is based on an extended UTAUT2 model, supplemented with constructs specific to the cryptocurrency ecosystem, including trust in technology, perceived risk, economic factors, value-based motivation, and libertarian political attitudes. Data were collected through an online survey of 106 Bitcoin users and analyzed using Cronbach's alpha, Pearson correlation, multiple linear regression, and hierarchical model comparison. The results show that the strongest predictor of the intention to use the Lightning Network is perceived usefulness, followed by perceived ease of use and facilitating conditions. The extended constructs, particularly trust in technology, perceived risk, and economic factors, significantly increase the explanatory power of the model. A notable finding is that general libertarian political values do not have a statistically significant effect on adoption, whereas the technology-specific value of decentralization does. The thesis shows that wider adoption of the Lightning Network depends primarily on emphasizing its practical technological and economic benefits, user-friendliness, and trust in security rather than on a general ideological narrative.
