Benefits of Blockchain Advantages and Disadvantages

Blockchain consists of two English words, namely block which means group and chain. Blockchain is a sequential block chain that is assembled and distributed together.

Blockchain is a recording technology behind the bitcoin network which was developed for digital data storage systems.

Blockchain Benefits

Blockchain Txn

Blockchains simplifies the entire transaction process and can be like to a digital ledger that can be accessed by anyone, anytime and anywhere without the need for approval from a bank institution.

Blockchains makes transactions more secure and transparent. So that it can minimize data misappropriation, such as bribery or corruption and illegal data theft.

Blockchain can not only be used in the financial field, but also in other fields. McKinsey once created a blockchains opportunity table for various fields such as telecommunications, property, health, agriculture, and media.

Advantages of Blockchain

The advantages contained in the blockchains are one of the factors why it is so favored by various groups. The advantages of blockchain include:

More transparent system

Blockchain is one of the most effective technologies for keeping track of information and transactions. In fact, the system has proven to be more secure and transparent.

In a transparent sense, when the transaction takes place, the public access can be seen by all parties without the need to login.

So that any information or funds owned by the user will not be used without the knowledge of the owner. This is very different from the banking system.

Better data security

The second advantage is better data protection than others. The blockchains database is append only, so it can only be added but cannot be repaired. The blockchain system is very difficult for hackers and hackers to penetrate.

Better audits

The third advantage is better auditing. That is, this blockchain can allow users to know the audit trail of their assets, so that risks related to embezzlement of user funds can be minimized.

Prevent middleman fees

The presence of this blockchains can indirectly eliminate the fees of middlemen or an intermediary (brokers) which sometimes add to transaction costs.

With the blockchains, all data recording and verification activities are directed and immutable.

More efficient transactions

With blockchains, transactions can be completed in minutes, not days. Unlike banking systems which are very limited, this blockchain technology can be operated all year round without stopping. Thus, this blockchain makes transactions more efficient.

More flexible data storage

This blockchain technology makes data storage more flexible because the blockchains can store any data according to the field it is implemented in.

For example, such as medical history of hospital patients, land certificates and home ownership and even employment contracts can be stored in the blockchains.

Disadvantages of Blockchain

In addition to having advantages, this blockchains also has disadvantages that need to be known. The disadvantages of blockchain include:

Expensive cost

Although blockchain technology can reduce transaction costs, the process of customizing this system can only be done by a few people.

This relatively new technology still has few experts in the blockchains field. This is what makes the manufacturing process very expensive.

Not environmentally friendly

If we look at bitcoin mining or bitcoin mining, the electricity consumed by these super-sophisticated computers is very large. Let’s just say, one computer can use the resources equivalent to 100 ordinary computers in general.

So that many environmentalists are aware of and protest to bitcoin miners because the mining process is considered environmentally unfriendly.

Means of crime

Although data security is very well maintained in the system, it does not rule out the possibility that blockchain technology can be misused as a means of crime. For example, illegal buying and selling transactions, terrorism financing and money laundering.
