While the blockchain technology has been hailed as a major breakthrough, it is not without its own issues. Blockchain technology is still in the early stages of its development, and a number of problems have cropped up that are still awaiting some level of resolution. Decentralized networks such as blockchains have their own unique challenges.
In this chapter, we'll look at the following key issues in blockchain:
- Scalability and decentralization
- Scalability and costs
- Usability
- 51% attacks
- Network forks
- Catastrophic bugs
- Lack of interoperability
- Low availability of blockchain skills
