What are the disadvantages of blockchain
Blockchain allows you to store data distributed, ensures the security of transactions and protects against centralization. But this technology has two important drawbacks.
Every coin has two sides, and a stick has two ends. The same applies to new technologies. Blockchain for storing information has revolutionized the information field. But before deciding to use it for practical purposes, you need to know what the disadvantages of the blockchain are. We will talk about this further.
Unconfirmed coin transfer transactions
To send money to the provided address, the user must independently initiate this operation and send a request to attach the record to the blockchain. But sometimes it happens that the registry does not accept the operation and does not include it in the next block.
There may be several reasons:
- Absence of the required amount in the account. The user is trying to send coins that he does not have. The bottom line is that the registry does not store information about the number of coins, but calculates it from the history of transactions. If it turns out that the amount is not enough, the operation is rejected.
- Wrong commission. In some transactions, the user can adjust the amount of the commission. If it is too small, taking into account the current load on the network, the operation may not occur.
That is, in the blockchain, the need to control the sending of funds is assigned to the user. He must make sure that the amount is gone and reached the addressee. This process can be tracked through the link to the registry.
The amount of data stored
The second significant drawback of the blockchain is the ever-growing amount of stored data. Each network member with a “heavy” wallet keeps a copy on their computer. And it stores all the data from the moment the registry was created to the current minute. That is, data volumes are calculated in gigabytes. To accommodate them, you have to use more and more capacious drives.
But the minus of a large volume is also that as the “chain” grows, operations will take place more and more slowly.
In addition, this registry is constantly synchronized with other users. Therefore, the amount of data transmitted over the network is increasing all the time. And this process happens in real time. If the network bandwidth is low (for example, in the case of private blockchains), there may be problems with transaction processing.
But despite the disadvantages of the blockchain, this technology is truly revolutionary. And new developers are struggling with current shortcomings, who are improving existing platforms and developing new projects
