Blockchain applications still face several technological challenges, e.g. scalability. But the real challenges are different.
Which applications can benefit right now from distributed ledger technologies? And where we still need to wait some years before blockchain technology will be adopted?
In which areas it is possible to use blockchain technology? What is the regulator’s view?
Are smart contracts legally binding? Are records kept in a blockchain enforceable? Who will drive the change: lawmakers, regulators or industry bodies?
How to agree on common standards in public blockchains? How to manage and to further develop those standards at a later stage with broad public consent?
How to manage private blockchains without a central database? How to create trust?
- Transparency and anonymity:
What is the right level of transparency? Is pseudo-anonymity acceptable for most use cases or do we need something different?
