The Challenges Of Blockchain Technology
Blockchains are attractive because they are decentralized, open-source, and transparent, but they also come with their own set of challenges. Key concerns are the need for cryptographic hash functions to generate proof-of-work, making performing calculations on a blockchain much more resource-intensive than other public databases. Also, blockchain consensus protocols like Proof-of-Work involve high energy consumption and may not be sustainable in the long term. Other blockchain services today lack strong user privacy protections.
A few blockchain projects (such as Factom) are developing privacy methods. However, their ability to protect user’s sensitive information is limited by the kind of data stored on blockchains. Similarly, decentralized applications (apps) running on top of a blockchain system typically only handle the exchange of cryptocurrency tokens and not traditional forms of currency like dollars or euros. The result is that apps and blockchains are highly interoperable, but their interactions do not go beyond cryptocurrencies.
Most of these limitations will be addressed in time as blockchain technology continues to evolve and mature. For now, they pose challenges that must be overcome for blockchains and apps to be successful and widely adopted by the mainstream public.
Future Of BlockChain Technology
Although it is still relatively early, several projects are working to make blockchains more scalable. For example, Ethereum developers are preparing to switch their platform from a proof-of-work consensus algorithm to “proof of stake,” which requires less computational resources and may eventually allow for millions of transactions per second, even on smartphones.
However, the biggest challenge facing the future of blockchain technology is adopted. Like any new technology, it can be difficult to convince consumers and businesses alike to embrace something radically different from what they are accustomed to. Another critical priority is allowing blockchains to interoperate with each other so that users do not need to rely exclusively on one blockchain for every application they desire.
Conclusion
Blockchain technology is an exciting new development that has tremendous potential to improve how people do business with each other. Although it’s still early days, many companies are investing in blockchain R&D, and the industry’s growth is expected to continue for years to come!
