Blockchain applications still face several technological challenges, e.g. scalability. But the real challenges are different.
- Use-Cases:
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? - Regulation:
In which areas it is possible to use blockchain technology? What is the regulator’s view? - Legal:
Are smart contracts legally binding? Are records kept in a blockchain enforceable? Who will drive the change: lawmakers, regulators or industry bodies? - Standards:
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? - Governance:
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?
