How Blockchain Works? Blockchain is a decentralized transaction and data management technology developed first for Bitcoin cryptocurrency. The interest in Blockchain technology has been increasing since the idea was coined in 2008.

Currency transactions between persons or companies are often centralized and controlled by a third-party organization. Making a digital payment or currency transfer requires a bank or credit card provider as a middleman to complete the transaction. In addition, a transaction causes a fee from a bank or a credit card company.

Blockchain is a distributed database solution that maintains a continuously growing list of data records that are confirmed by the nodes participating in it.

The data is recorded in a public ledger, including information on every transaction ever completed. Blockchain is a decentralized solution that does not require any third-party organization in the middle.

However, even though Blockchain seems to be a suitable solution for conducting transactions by using cryptocurrencies. So, it has still some technical challenges and limitations that need to be studied and addressed.

High integrity of transactions and security, as well as privacy of nodes, are needed to prevent attacks and attempts to disturb transactions in Blockchain.

Blockchain, mostly known as the technology running the Bitcoin cryptocurrency, is a public ledger system maintaining the integrity of transaction data. Blockchain technology was first used when the Bitcoin cryptocurrency was introduced. To this day, Bitcoin is still the most commonly used application using Blockchain technology.

 Bitcoin is a decentralized digital currency payment system that consists of a public transaction ledger called Blockchain.

The essential feature of Bitcoin is the maintainability of the value of the currency without any organization or governmental administration in control. The number of transfers and users in the Bitcoin network is constantly increasing.

Blockchain technology has also some technical challenges and limitations that have been identified.

  1. Throughput: The potential throughput of issues in the Bitcoin network is currently maximized to 7tps (transactions per second).
  2. Latency: To create sufficient security for a Bitcoin transaction block, it takes currently roughly 10 minutes to complete one transaction.
  3. To achieve efficiency in security, more time has to be spent on a block because it has to outweigh the cost of double-spending attacks. Double-spending is the result of the successful spending of money more than once.
  4. Size and bandwidth: If the Blockchain needs to control more transactions, the size and bandwidth issues have to be solved.
  5. Security: The current Blockchain has a possibility of a 51% attack. In a 51% attack, a single entity would have full control of the majority of the network’s mining hash rate and would be able to manipulate Blockchain. To overcome this issue, more research on security is necessary.
  6. Wasted resources: Mining Bitcoin wastes huge amounts of energy ($ 15 million/day). The waste in Bitcoin is caused by the Proof-of-Work effort.
  7. Usability: The Bitcoin API for developing services is difficult to use. There is a need to develop a more developer-friendly API for Blockchain.

This could resemble REST APIs. Versioning, hard forks, multiple chains: A small chain that consists of a small number of nodes has a higher possibility of a 51% attack. Another issue emerges when chains are split for administrative or versioning purposes.

Overall, Blockchain as a technology has the potential to change the way how transactions are conducted in everyday life.

Blockchain technology runs the Bitcoin cryptocurrency. It is a decentralized environment for transactions, where all the transactions are recorded in a public ledger, visible to everyone.

Finally, the goal of Blockchain is to provide anonymity, security, privacy, and transparency to all its users. However, these attributes set up a lot of technical challenges and limitations that need to be addressed.

What is blockchain technology?

Blockchain technology is a software; protocol for the secure
transfer of unique instances of value (e.g. money, property,
contracts, and identity credentials) via the internet without
requiring a third-party intermediary such as a bank or government
