Low Security – Hackers are able to access your private key
Hackers can easily access your private keys, which give them access to your funds, which is one of the disadvantages of blockchain technology. Furthermore, if you lose your private key, there is no way for you to retrieve it, meaning you could lose access to your funds for good. For example, if a hacker gained access to your private key and transferred your cryptocurrency from an exchange to their wallet, you would be out of luck. The only way to retrieve your cryptocurrency would be if you found the hacker and convinced him or her to return it. In addition, hackers are able to target computers running in online mode with malware (software designed to damage or disable computers). If hackers manage to take control of your computer, they can steal your cryptocurrency just like they did with Mt. Gox. Fortunately, one of the advantages of blockchain technology is that transactions are made publically available on the ledger. However, this also leaves you vulnerable to tracking by third parties and governments.
The decentralized nature of blockchain makes it less secure than systems with centralized servers. If one node fails, then the entire network fails which makes hacking easier. The increased dependence on computers means there are many points where something can go wrong which can lead to data loss or corruption.
Slow Transactions
As a consequence, blockchain technology has many disadvantages, including the fact that transactions may take hours to complete. The reason for this is that each block needs to be verified by every node on the network before it can be added to the chain. This poses a problem if you want to buy a coffee quickly. Your transaction may take some time to go through. Bitcoin transactions, for instance, typically take about ten minutes. Transactions on Ethereum and Ripple usually take just a couple of seconds. The exact time will depend on the type of blockchain project you are using. Buying some cryptocurrency may not be a problem if your objective is merely to store medical records, but sending payments internationally and storing medical records may be problematic.
Less Scalability
A disadvantage of blockchain technology is that it is not very scalable, so it is limited in how many transactions it can handle per second. In comparison to Visa, which can handle 24,000 transactions per second, Bitcoin can only handle seven transactions per second. In addition to this, scalability of blockchains is also difficult since they become more expensive as they grow. As Bitcoin's blocks grow from 1MB to 2MB, transaction costs would drop from $1 to $30 instead of $1. It is estimated that the number of transactions on the Bitcoin network will be around 100,000 in 2020 and 10 million by 2040. For Ethereum, blocks have grown from 32KB to 67KB, and for Monero the maximum block size has increased from 1MB to 4MB without affecting the rate at which these networks are scaling. Disadvantages related to scalability with blockchain is that If too many people are trying to access the network at once, transactions will slow down and fees will increase.
Reduced Control by Centralized Entities
One of the disadvantages of blockchain technology is that it gives centralized entities less control. With blockchain, there is no central authority that can make decisions or control the network. This can be seen as an advantage by some, but it also means that there is no one to turn to if something goes wrong. For example, with traditional systems a company has a legal department and various other employees in charge of making decisions. If there are issues they are able to step in and fix them quickly. With blockchain, if something goes wrong then it's up to the users on the network to come together and work out a solution themselves- this may not always happen. It's true that having multiple parties working on a project can be beneficial because they each have different strengths and knowledge, but it doesn't mean they will automatically agree on what needs to be done. In these cases, you'll need to rely on your own personal skills and knowledge which might not go down well with everyone else who was involved in the project.
Consumes Large Amounts of Energy
One of the disadvantages of blockchain technology is that it consumes large amounts of energy. This is due to the fact that blockchain relies on a process called mining in order to verify and add transactions to the public ledger. In order to mine, computers must solve complex mathematical problems, which requires a lot of energy. As more and more people use blockchain technology, the amount of energy needed to power the network will continue to increase. Mining Bitcoins can also be an expensive endeavor because of the high costs associated with mining hardware as well as electricity costs.
In order to address this issue, many companies are trying to find ways to lower energy consumption levels through developing new types of hardware or by implementing new software systems that require less computing power for the verification process.
One way blockchain can be a disadvantage for consumers is if they have issues with their internet connection or electricity grid and are unable to access their data or make changes via blockchain, making it difficult for them to participate in this growing market. On the other hand, while there are some disadvantages of using blockchain, it is still one of the most secure methods available today. The decentralized system and redundancy within blocks provides protection against hacking attacks while still giving users control over their personal information.
Government Regulations
One of the disadvantages of blockchain is that governments are unable to regulate it. This means that there is no way to control or monitor the transactions that take place on the blockchain. This could lead to illegal activities taking place on the blockchain without anyone knowing about it. Additionally, because blockchain is decentralized, there is no one entity that is responsible for the network. This could make it difficult to hold anyone accountable if something goes wrong. Another disadvantage of using blockchain is the difficulty in finding out who has the rights to a specific address and who doesn’t. There can be multiple people with access rights to an address, which makes it more difficult for law enforcement agencies and others involved in legal proceedings to investigate crimes committed online. These same issues will also apply when data breaches occur. The individual being investigated may not even know what happened at all as they were not even made aware of the breach.
Hence, a disadvantage of blockchain technology is that government regulation cannot be enforced on this technology; additionally, because blockchain is decentralized, there is no single person or entity in charge.
Legitimate Uses are Scarce
Despite all of the advantages of blockchain technology, there are still some disadvantages that need to be considered. One of the main disadvantages is that licit uses for blockchain are still relatively scarce. While there are numerous implicit operations for the technology, utmost of them haven't been realized or enforced yet. This lack of real- world use cases makes it delicate to justify investing in blockchain technology. also, blockchain technology is still in its early stages and has not been completely tested. numerous people view this as a disadvantage because it means that there could be pitfalls associated with using the technology. As a result, companies are cautious about espousing blockchain into their operations until they know further about how secure it is.
Centralization & Volatility
One of the disadvantages of blockchain technology is that it is often centralized. This means that there is a single point of control, which can be susceptible to corruption. Additionally, blockchain technology is often volatile, meaning that the value of cryptocurrencies can fluctuate wildly. This can make it difficult to use blockchain technology as a reliable store of value. A disadvantage of using blockchain is that due to its volatility, investors may not be able to invest in anything else other than cryptocurrency. For example, if an investor purchased 100 bitcoin on January 1st 2017 and sold their coins on January 2nd 2018, they would have made over $1 million. On the other hand, if they had purchased $100 worth of bitcoins on December 31st 2017 and sold them on January 2nd 2018, they would have only made about $1300 from their investment.
Conclusion
Although blockchain has many advantages, there are also several disadvantages of this technology. Disadvantages related to security issues, slow transactions, scalability, reduced control by centralized entities, big energy consumption problem, government regulations issue, low volume of legitimate uses, centralization & volatility things can come in the place when one can go to adopt blockchain technology. These above mentioned disadvantages of blockchain can be regarded carefully before implementing this technology.
