Advantages and Disadvantages of Blockchain Technology
If you are interested in technology, surely you have heard of blockchain (or chain of blocks). Many experts say it represents a new revolution, after what the internet represented. And the truth is that there are multiple companies that are beginning to use some applications of the chain of blocks. But what are the advantages and disadvantages of blockchain technology?
Blockchain: Advantages and Disadvantages
Advantages and disadvantages of blockchain
In other articles, we have explained in detail what blockchain means. In summary, the blockchain technology or blockchain is nothing more than an encrypted ledger or accounting book, although with certain peculiarities that multiply its uses.
Specifically, what blockchain does is record each of the transactions or operations carried out on its platform and link them chronologically to each other through sets of data called blocks. In addition, all the data are encrypted, which provides a layer of security over the information stored in the database.
Blockchain transactions are authorized autonomously, which compared to other traditional technologies, saves time and numerous costs. If you want to learn about blockchain, we recommend the guide on what blockchain is.
But these are not the only benefits of blockchain. Blockchain is being applied in numerous areas, ranging from commerce, entertainment, and of course, cryptocurrencies. But what are its disadvantages? Below, we detail the main advantages and disadvantages of using blockchain.
Blockchain Advantages
- Blockchain focuses on security. Encryption, protection against double spending, and approval systems (such as Proof of Work or Proof of Stake) offer more guarantees than other traditional databases.
- Blockchain is based on decentralization. No organization or government can modify the price of cryptocurrencies and alter the value of your financial assets.
- Transactions are very fast, regardless of where they are made. There are numerous blockchain platforms (such as bitcoin or ethereum), but in almost all cases, they will not take more than a few minutes. On the other hand, international bank transfers can take days or even weeks.
- Blockchain-based platforms are always available. You can use them 24 hours a day, 365 days a year.
- Each transaction requires a certain amount of cryptocurrencies to be executed. However, this cost is more economical than what other methods offer.
- It is a transparent system. Forget about banks, where you have no idea what they do with your money. Blockchain platforms are public, and anyone can check their transactions.
- Transactions cannot be modified. Therefore, their information is immutable, providing extra security to the stored information and protection to the users who use it.
- You have control over the information of all your transactions.
- The blockchain has many applications. In the following article, you can find many examples of blockchain usage.
Disadvantages of blockchain
- It is a developing technology. Its novelty means that it is not yet fully evolved and its full potential is not yet known.
- This novelty also poses an implementation difficulty. Its introduction into companies has a high initial installation cost, so it will likely take some time to be globally adopted.
- The authorization methods require too many resources. These approval systems are automated, eliminating intermediaries and saving costs and time. However, most blockchain platforms work with the Proof of Work system, which requires mining. Mining requires thousands of connected computers, resulting in high energy consumption. Fortunately, other systems are being developed, such as Proof of Stake, which would solve this problem.
- Blockchain is immutable. Although we have presented it as an advantage, it is also one of the disadvantages of blockchain. If you make a mistake or fall victim to a scam and send cryptocurrencies to a fraudulent address, you will lose them and will not be able to recover them.
- The network speed can vary depending on its saturation. This is common with traditional technology, such as cloud servers, which blockchain technology has not been able to solve.
- Impossibility to recover lost accounts. If you lose the access keys to a blockchain address, you will permanently lose access to it. In the case of cryptocurrencies, if you lose the keys to your wallet, it would be like losing a banknote.
Pros and Cons of Blockchain
In summary, blockchain is a technology that promises to revolutionize a multitude of services that use intermediaries, such as finance, commerce, logistics, or entertainment.
However, not all its applications are known yet, and being a developing technology, it still has certain procedures that need to improve its efficiency, which is one of the main disadvantages of blockchain.
Still, it seems that the blockchain has come to stay, and in the coming years, we will discover even more uses of this extraordinary technology.
