Global events could reignite the appetite for change, but until they do, blockchain could remain a hard sell for many. Back in 2015 one former boss at Barclays described the interest and apparent enthusiasm of his sector as “cynical” – stating that it stems from a desire to exert control or even block the usefulness of the emerging technology. However, it isn’t necessarily the cure-all panacea for the world’s problems that many evangelists would have you believe.
As the blockchain industry continues to grow and diversify, cultivating interoperability among different networks will be crucial for realizing the technology’s full potential. By breaking down silos and promoting collaboration between various blockchain platforms, the industry can work towards creating a cohesive, efficient, and inclusive digital landscape that benefits users, developers, and businesses. The process of validating transactions on a blockchain network requires a lot of computing power, which in turn requires a lot of energy.
This fragmentation can also hinder collaboration, stifle innovation, and prevent the seamless exchange of data and value between different blockchain ecosystems. Interoperability, or the ability of different blockchain networks to communicate and interact with each other, is another crucial challenge facing the industry. There are currently many different blockchain platforms — each with its own protocols and standards – and they often do not work well together. Blockchain technology has undeniably captured the imagination of the tech world and beyond, offering the promise of decentralized, transparent, and tamper-proof systems. From its inception with Bitcoin to the development of smart contracts, non-fungible tokens, and decentralized finance, blockchain has been hailed as a groundbreaking innovation with potential applications in numerous industries.
- Nevertheless, it’s an important consideration and the environmental implications as well as the energy costs can’t be ignored.
- Some blockchain projects have adopted alternative consensus mechanisms, such as PoS, which consume significantly less energy.
- These chains – really just computer files, after all – have the potential to become slow and unwieldy as they grow in size, and the number of computers accessing and writing to the network grows.
- Blockchain networks can be slow and inefficient due to the high computational requirements needed to validate transactions.
The 5 Big Problems With Blockchain Everyone Should Be Aware Of
While these efforts are promising, it is crucial for the blockchain community to continue exploring ways to minimize energy consumption and develop environmentally sustainable solutions. And while blockchain experts are making some progress, achieving scalable, efficient, and decentralized blockchain networks remains an ongoing challenge that needs further exploration. But along with blockchain’s advantages come some significant challenges — and to reach its full potential as a game-changing technology, these issues will need to be overcome.
Interoperability
This has led to concerns about carbon emissions and the environmental impact of blockchain technology. Blockchain networks can be slow and inefficient due to the high computational requirements needed to validate transactions. As the number of users, transactions, and applications increases, the ability of blockchain networks to process and validate them in a timely way becomes strained. This makes blockchain networks difficult to use in applications that require fast transaction processing speeds. To mitigate risks, companies are working to improve the security of blockchain networks and applications.
Energy Consumption
Their security efforts include formal verification of smart contracts to help identify potential vulnerabilities and using multi-signature wallets for storing and managing digital assets. Blockchain is a complex technology that requires a high level of technical expertise to implement and maintain. Tech challenges may hinder the widespread adoption of blockchain technology and discourage potential users and developers from engaging with it. As blockchain technology continues to evolve, ensuring the security of users, assets, and transactions is still a concern.
Interoperability
Traditional blockchains like Bitcoin and Ethereum rely on consensus algorithms like proof-of-work and proof-of-stake, which can be slow and resource-intensive. As a result, these networks face limitations in transaction throughput, often leading to congestion and high transaction fees. In my opinion, however, although these five issues could pose significant hurdles, it likely that blockchain technology will evolve over the coming years. After all, technological advancement, much like nature, has a way of finding its way around artificially constructed barriers. Some blockchain projects have adopted alternative consensus mechanisms, such as PoS, which consume significantly less energy.
- Taking the most widely known and used blockchain as an example – Bitcoin – last year it was claimed that the computing power required to keep the network running consumes as much energy as was used by 159 of the world’s nations.
- Hopefully this is a problem which will be solved with advances in engineering and processing speeds, but at this point in time it remains a problem, nonetheless.
- Banks make huge amounts of profit from playing the middle-man role, and because the cost is distributed among their millions of customers, end users usually pay very little individually.

Yes, Bitcoin’s blockchain is a hugely valuable network – with a current market capacity at the time of writing of over $170 billion – so sophisticated and computationally intense security is essential. Smaller scale blockchains – such as those that an organization may deploy internally to securely monitor and record business activity – would consume a fraction of that. Nevertheless, it’s an important consideration and the environmental implications as well as the energy costs can’t be ignored.

Efforts to address this issue include the development of user-friendly interfaces, streamlined onboarding processes, and educational resources that simplify the complexities of blockchain. Increased collaboration between industry experts, academia, and government bodies can also promote the sharing of knowledge and the creation of standardized protocols and frameworks that reduce barriers to entry. Various solutions have been proposed to try to overcome scalability issues, including scaling systems for creating off-chain channels that allow for faster and more cost-effective transactions. Banks make huge amounts of profit from playing the middle-man role, and because the cost is distributed among their millions of customers, end users usually pay very little individually. Ten years later and with no apparent danger of immediate repeat, is there still an appetite for wholesale tearing down of financial services and rebuilding it from scratch?
Blockchain relies on encryption to provide its security as well as establish consensus over a distributed network. This essentially means that, in order to “prove” that a user has permission to write to the chain, complex algorithms must be run, which in turn require large amounts of computing power. Taking the most widely known and used blockchain as an example – Bitcoin – last year it was claimed that the computing power required to keep the network running consumes as much energy as was used by 159 of the world’s nations. Blockchain’s security measures have often been touted as key strengths of the technology — but the security of blockchain networks is not without its challenges. There have been instances of security breaches and hacking attacks on blockchain networks, and these problems can result in monetary losses and damage to the integrity of the network. This lack of interoperability can lead to inefficiencies, as individuals and companies may need to navigate multiple platforms and use a number of tokens or cryptocurrencies to interact with different networks.
