The Top Biggest Problems Related To Blockchain Technology 

  • Blockchain technology has the potential to improve security and accessibility, but it still has issues.
  • Security is a major concern, as blockchain networks have experienced security lapses 

With the promise of decentralized, transparent, and tamper-proof networks, blockchain technology has unquestionably captivated the attention of the tech community and beyond. Blockchain has been lauded as a ground-breaking invention with potential applications in many industries, from its birth with Bitcoin through the development of smart contracts, non-fungible tokens, and decentralized banking.

The security and accessibility of many goods and services across numerous industries have a lot to gain from the use of blockchain technology. But despite all of its potential advantages, blockchain still has a number of issues that numerous developers are trying to fix.

Problems With Blockchain Technology 


The consensus methods used by traditional blockchains like Bitcoin and Ethereum, such as proof-of-work and proof-of-stake, can be slow and resource-intensive. Because of this, these networks’ throughput constraints for transactions frequently cause congestion and high transaction costs.

Scalability problems have been addressed in a number of ways, including scaling systems for off-chain channels that enable quicker and more affordable transactions. This restriction results from the consensus technique most blockchain networks employ, which calls for each network node to process each transaction. As the network expands, there will be more transactions to process, which will mean longer processing times and higher transaction costs.

Consumption Of Energy

Blockchains that use a proof-of-work algorithm to choose which node has the privilege of confirming the following block in the chain might take a lot of energy. Both Bitcoin and Ethereum employ the proof-of-work approach, in which nodes compete to find the quickest solution to a challenging problem. 

As the network expands, there are more competitors and a greater competition for computer resources, which uses energy. Because only one node will ultimately granted the privilege of confirming the following block, the energy consumption is incredibly inefficient.

Many blockchain networks, including Bitcoin, use the proof-of-work (PoW) consensus mechanism, which calls for nodes to solve challenging mathematical puzzles in order to add new blocks to the blockchain. This process requires a substantial amount of energy, and estimates indicate that Bitcoin uses about as much energy as a small nation.


The security of blockchain networks is not without its issues, despite the fact that it has frequently cited as one of the technology’s primary virtues. Blockchain networks have seen security lapses and hacking assaults in the past, and these issues can cause monetary losses and harm to the network’s integrity.

Businesses are attempting to increase the security of blockchain networks and apps in order to reduce risks. Their security measures include using multi-signature wallets for storing and managing digital assets, formal smart contract verification to help identify potential vulnerabilities, and other measures.


Blockchain transactions are rather quick for account-to-account transfers, but because they are decentralized, they may not be the best option for regular transactions.

Since a blockchain like the one used by Bitcoin is completely decentralized, a transaction has no guarantees until it has verified on the blockchain. Since the Bitcoin blockchain can only process a small number of transactions per second, that could take a while. For an hour, a retailer might not be aware of whether a transaction actually went through. Even while there are many effective blockchain applications in the financial industry, that makes it impractical for the majority of retail transactions.


It takes a high level of technical ability to implement and maintain the complicated technology known as blockchain. Blockchain technology adoption may be hampered by technical issues, which may also turn off potential users and developers. The intricacy of blockchain technology might cause implementation mistakes and inefficiency.

The creation of user-friendly interfaces, quicker onboarding procedures, and teaching materials that demystify the complexity of blockchain are all efforts to address this issue. Increased cooperation between academic institutions, business leaders, and government agencies can also encourage knowledge exchange and the development of standardized frameworks and protocols that lower entrance barriers.


Decentralized authority indicates that there is no single entity with the authority to uphold law and order within the network. There are no moderators, leaders, or even oversight organizations.  The fact that blockchain technology operates in a legal grey area makes it challenging for organizations like enterprises and governments to accept and implement it. Uncertainty and potential innovation barriers may result from unclear legislation in the industry.

The absence of global standards exposes developers to risks and difficulties when they attempt to build blockchain-based solutions across diverse platforms.


Blockchain is a very young and developing technology that has yet to properly address many of these challenges, despite the potential it has to revolutionise a wide range of businesses.

At the end of the day, blockchain promises to increase the speed and security of numerous data transport and storage procedures. Despite the issues it may currently have, there will inevitably be more reasons to use blockchain as a solution as our lives become more digital.
