Blockchain is a system of recording information in a way that makes it difficult or impossible to change the system.

A blockchain is a digital ledger of transactions that is distributed across the network of computers on the blockchain.

 In addition, the block can contain a number of transactions.

The transactions varies based on the type of block.

Moreover, the record of that transaction can be by simply adding every participant’s ledger.

Often times, the participants transactions are all on the blockchain.

Furthermore, Blockchain is a type of DLT that users can be recording transactions with an immutable cryptographic signature.

This cryptographic signature is called a ‘hash’.

This means if one block in one chain was not in use or if the user decides to change it.

However it can be immediately apparent it had been tampered with.

Although If hackers wants to corrupt a blockchain system, they would have to change every block in the chain.

This cuts across all of the available and distributed versions of the chain.

However, this will significantly add to the security of the ledger.

In this article, you will learn about some of the negative effects of blockchain technology in education;

1. It is expensive: Blockchain technology is expensive to maintain.

Schools and school owners who are on a very low budget cannot afford it.

It becomes difficult for them to use the technology.

Because it is very costly and expensive to use.

2. It is difficult to maintain: Blockchain technology is very difficult to maintain.

However, if there is any data or information error. The data can be on the chain but it will not be easy to verify it. In situations where the information is in a ledger or log book. The errors in the data will not be easy to correct or change. this can make things difficult for the users.

3. It is slow: The database used for blockchain technology is very slow. In addition the adaption rate can take a long time.

Because it can be for several functions and operations.
