Introduction
Blockchain is a distributed ledger technology that can be used to store data in a way that prevents tampering with it. It operates according to protocols created to help parties that do not trust one another get an understanding so they may cooperate to accomplish various goals that are advantageous to the entire group.

Disadvantages
They are-
Private Key Issues
Individual private keys are the building blocks of blockchain addresses. In other words, each individual with access rights uses a private key to perform actions. Public-key blockchain procedures are the subject of cryptography. Individuals can access this public key address using their private keys as stated above. The procedure is rendered ineffective if the person misplaces their private key. They have no control over how their money will be saved or how the transaction will proceed. Using this private key is like running our bank. Blockchain technology is a huge failure as a result of the private key difficulties.
Extremely Volatile
The blockchain-based coins have a high level of volatility. Of course, one excellent illustration of that is the daily variations in the price of bitcoin. The fact that decentralised blockchain technology and virtual currencies are newcomers to the market is one of the causes of this volatility.This indicates that whether businesses, governments, or other organisations adopt them or not will undoubtedly affect the volatility. This is a significant decline, and the level of volatility is worrying those considering investing in Bitcoin or any other cryptocurrency.
Issues in Scalability
Many claim that Blockchain technology and Bitcoins are the best forms of money. Even yet, it's estimated that this network can only handle seven transactions per second. The system is distributed, as we stated, therefore it is crucial to verify transactions under each node. There is a limit to the amount of transactions per node when scalability difficulties are taken into account. Users may occasionally need to spend several hours performing their tasks. According to some, it is not possible to increase the number of active users in accordance with the blockchain's transaction speed. Traditional banking processes are faster and more flexible than blockchain.
Security Issues
Compared to all previous transaction procedures, it is claimed that Blockchain technology delivers the highest level of security. However, research indicates that Blockchain technology is vulnerable to a 51% attack, therefore it is not entirely safe. Sometimes a 51% attack is so crucial that the attackers can unquestionably take control of the system. Double spending will also have an impact on such a network. The bitcoin system's anonymity exacerbates the security risk. Although anonymity is valued, it can be challenging to identify those trying to conduct illegal operations here. The current drawback of blockchain technology is less transparency.
Data Modification is Difficult
It is challenging to add or edit data with blockchain technology once it has been recorded. It is regarded as one of the main benefits and drawbacks of blockchain technology. Data modification requires rewriting programmes and involves a lengthy procedure, which is a drawback. Sometimes too much stability can have a negative impact on systems. The primary drawback of blockchain technology in this situation is the irreversible records and labour-intensive updating process.
The Bottom Line
When Satoshi Nakamoto released a study in 2008, the blockchain technology gained its first notoriety. The term "A peer-to-peer electronic cash system" was used to describe the research study.
