Other challenges

In addition to key issues such as privacy and scalability, there are a few other challenges that can hinder the adoption of blockchain as a mainstream technology. We'll discuss these challenges and some possible solutions next.

Interoperability

We discussed interoperability briefly earlier in this book. It is sufficient to say here that interoperability is an open challenge and while many initiatives such as Cosmos, Polkadot, and Interledger are in progress to address this limitation, there is still a long way to go. One of the approaches is standardization of blockchain protocols, thus making them compatible with one another.
