What is blockchain and what's it's Advantage and Disadvantage.

What is Blockchain?

Blockchain is a digital distributed ledger that can be used to track transactions between two parties efficiently and in real time.It has the potential to revolutionize the way we do business and make it more secure, transparent, and efficient.

Blockchain technology can also help reduce fraud and increase transparency in industries such as finance, healthcare, government, and more.

Advantage of Blockchain:

1. Decentralized: No one person or organization owns or controls blockchain; instead, all participants have equal access to information and updates.

2. Easier: There's no need for middlemen like banks or governments because transactions are recorded on the blockchain itself, rather than in a central database. It's also much faster—you won't have to wait days for your money to reach its destination!

3. More secure: With blockchain, you know who owns what and how much they own, so there's no risk of fraud or theft because everything can be tracked back to its source.

4. Distributed Ledger Technology: is a system of recording data on multiple computers. It's often used in the financial industry to create digital records of transactions, but it can be used for much more than that!
5. It's transparent: Each transaction between two parties is recorded on a public ledger called "the blockchain." Which Provide flexibility and transparency. 

Disadvantage of Blockchain:

1. Private blockchain: is a closed, centralized system. It's not as secure as public blockchain and it doesn't allow for transparency. The main reason for this is that private blockchains are managed by a single entity and therefore can only be used in limited circumstances (e.g., when you want to do an internal transaction).

2. Scalability: refers to the ability of a system to handle more users. The blockchain is not currently scalable because it has limited capacity and can only handle so many transactions at once. The solution is to add more nodes, which requires more energy and hardware

3. Energy Consumption: Mining is the process of adding transaction records to Bitcoin's public ledger of past transactions (and a verification of those records). It also creates new bitcoin. These transactions are verified by network nodes through the use of cryptography and recorded in a public database known as the blockchain. Mining is an integral part of Bitcoin mining, which was designed so that it would be difficult to create any significant number of coins without having your hardware perform repetitive computations over and over again. The result? Miners have been rewarded with 12-15% profits per year on average, making this industry one of the most lucrative in existence today!

4. Lack of Regulations: You may be wondering what these standards are, or if there is a single one. There isn't. The blockchain industry has been growing rapidly, but the lack of regulations and standardization means that each company has their own set of rules and guidelines for how they use their technology. This means that even though your credit card company is using blockchain technology to send you money through its system, it's not necessarily going to do everything in its power to make sure this transaction goes smoothly—it could take days or weeks before your funds are transferred into your bank account (or anywhere else).

5. Blockchain offers a number of benefits, but these benefits are not without downsides: Blockchain is not a panacea. It has many issues to overcome and, as with any new technology, there are potential problems that may arise as it matures.

Conclusion

Blockchain technology has many benefits and is currently the most promising solution for many problems that we face as a society. But there are also some downsides to this technology, which will need to be considered before widespread adoption takes place.
