Blockchain and cryptocurrencies the future. So are cryptocurrencies and blockchains a fad? Should we care? Is there a future for these in the world of finance? While blockchain technology offers so much potential, as we can see from our discussion, there are still a number of issues that need to be addressed.

Firstly, performance efficiency, with a key feature of the technology being distributed with all the parties in the network involved. This method will inherently be slow. Furthermore, the number of entities in the network will be a consideration raising issues in the form of scalability. Next, we have interoperability. Interoperability refers to inter network communication issues. While information within a network may be resolved from a broader business perspective, networks existing in isolation are not ideal. How should legitimate entities outside of a network be added to the network? And how about other related entities? Should their joining be based on permission or should it be permissionless? Next, we have security. Again, with distributed technology, many parties will be involved leading to a question of security to the network. Finally, while an objective of the distributed network approach is decentralizing authority, there are governance issues to be addressed. How can crimes in the real sector be prevented? How could financial stability in the financial sector be insured? And how can software in the tech sector be updated in some blockchain? And cryptocurrencies will play big roles in the future, but what forms will they be like? It is likely that we are at the beginning of the blockchain. Cryptocurrency evolutionary cycle and changes will continue to come. Other future contenders for the future of money include central bank digital currencies, cbdc and corporate issued currencies such as Facebook's DM currency, and JP Morgan's, JPM coin as an example of the evolutionary cycle and changes that are still to come. Here is the latest from Elon Musk.
