The blockchain technology has shown that it is possible to maintain a
common ledger consistently and securely among a group of
self-interested users. By this technology, it has become possible to
implement solutions without a trusted authority which were previously
thought to require one. Bitcoin, the most important application of the
technology, demonstrated how to implement a secure payment system in a
distributed manner. Many other applications of blockchain have been
proposed since Bitcoin, and prototypes and products have been
developed. However, although blockchain has been presented as a
disruptive innovation, the killer applications promised are yet to be
seen, and this has raised questions about the technology's real

 In this seminar, I will talk about the issues that have hindered a
widespread adoption of blockchain technologies. In this context, I
will discuss,

- the gap between user needs and provided features,

- lack of legal regulations,

- existence of more practical alternatives.
