Cons of Blockchain


Cons of Blockchain

These days, a lot of Blockchains are designed as distributed databases that function as digital ledgers. In these Blockchain ledgers, the data is held in chronological blocks and connected by cryptographic proofs. Blockchain has advanced past its infancy and is now capable of being used by businesses in its mature form, beyond its apparent uses for financial institutions. Numerous industries have profited from the development of Blockchain Technology, which increases security in unreliable contexts. What are you waiting for?

Top Disadvantages

They are- 

The distributed computing system blockchain is not one

Nodes are necessary for the correct operation of the blockchain network. The blockchain's quality is dependent on the nodes' quality. For instance, the robust blockchain of Bitcoin encourages nodes to join the network. The same cannot be said for a blockchain network where nodes are not rewarded. This indicates that it is not a distributed computing system in which the nodes' participation and involvement in the network are not necessary. In contrast, a distributed computing system strives to ensure that the transactions are verified in accordance with the rules, recorded, and that the transactional history is available for each transaction.  

A Challenge Is Scalability

As compared to their centralised counterparts, blockchains are not as scalable. If you have ever used the Bitcoin network, you are aware that the speed at which transactions are executed depends on how congested the network is. This issue is connected to blockchain network scalability problems. Simply put, the likelihood of a network slowing down increases as more users or nodes join it. However, the way blockchain technology operates is becoming more and more. Scalability solutions are also being integrated with the Bitcoin network with the proper technological growth. The answer is to only use blockchain for information storage and access, leaving off-chain transactions.

Certain Blockchain Solutions Use Excessive Energy

With Bitcoin, blockchain technology was first introduced. It utilises the Proof-of-Work consensus mechanism, which depended on the miners to perform the labour-intensive tasks. The miners are rewarded for figuring out challenging mathematical puzzles. These challenging mathematical puzzles are not well suited for use in the real world because of their high energy requirements. The miners must answer the puzzles each time a new transaction is added to the ledger, which consumes a lot of energy. But not every blockchain system operates in the same way. The issue has been resolved by different consensus algorithms. Because there are fewer nodes in permissioned or private networks, for instance, these issues are not present.     

As data is immutable, blockchain cannot go back in time.

One of the most significant drawbacks of the blockchain has always been the immutability of data. It is obvious that various systems, such as the supply chain, financial systems, and others, profit from it. You should realise that this immutability can only exist if the network nodes are dispersed equitably if you understand how networks operate. What I mean to say is that a blockchain network is susceptible to control if a single party owns 50% or more of the nodes. The fact that data cannot be deleted once it has been written is another issue it has. Everyone on the planet is entitled to privacy
