What is Blockchain Technology?

[Dreamer]

The blockchain is a breakthrough technology that powers many of the cryptocurrency networks that we recognize today. At a general level, blockchain technology showcases some of the most groundbreaking solutions to networking issues in human history. To explain what a blockchain is and how blockchain technology works, we will explain networks on an abstract level and then discuss the pros and cons.

Before Blockchain Technology – The Traditional Network System
A network, in precise terms, is a collection of points (nodes) with connections in between certain nodes. A practical example of this that has stood the test of time throughout human history is the mail network. If you want to create and support a system that allows messages to be sent between any two parties, you must first pinpoint their locations and find a courier to carry out the transaction. All systems that allow users to make transactions of any type, such as a telephone service or a shipping agency, use systematic networks to carry out their respective transactions.

Unfortunately, networks come with a set of inherent issues. The largest of these is security, both in ensuring that a transaction is recorded and processed, and preventing any outside interference from jeopardizing the transaction.

Imagine that you want to send a paycheck to an employee who lives in another neighborhood. Firstly, if the transaction is not recorded properly, there would be no legal evidence to certify  that the transaction ever took place. Secondly, if the paycheck is intercepted by a thief, the transaction is immediately compromised. Security issues like these are allow for modern-day fraud, theft and other crimes that imperil our financial security.

The next big issue of networking is network maintenance, or more specifically, how to maintain the connections, reliability and security of a network given a limited number of resources. When the Medicis ruled the financial world of Renaissance Italy, they required both thoroughly-inspected accounting books and physical groups of mercenaries to protect their wagons of gold from highwaymen en route to their destinations. It remains clear that whenever an individual or organization wishes to establish a reliable network, these issues must be taken into consideration. The blockchain as a network innovation addresses these very problems.

Blockchain is seen as a revolution within the virtual generation because its ideas reverse the principle of securing and stabilizing our data because sharing or transferring it is a long way off.

Blockchain is a record-keeping technology designed to make it impossible to hack the system or forge the data stored on it, thereby making it secure and immutable.

Blockchain is a system of recording information in a way that makes it difficult or impossible to change, hack, or cheat the system. A blockchain is essentially a digital ledger of transactions that is duplicated and distributed across the entire network of computer systems on the blockchain.

It just a one big hype word used to raise billions of capital In other words, it's a huge innovation transforming whole world and disturbing traditional finance such as banks, even governments! In DeFI we trust!

I think  we see many coins that based on block chain technology here.
Block chain technology will be adopted by many big companies at the coming future. Let's see.

Thanks for the good summary of the topic Blockchain is something I still find fascinating, even though I had trouble understanding it when I first got into the subject. Now, I’m very interested in this and also the different kinds of blockchain, like proof of work, proof of stake, and also proof of personhood. Each has its own pros and cons.

Blockchain is a type of database that is specific to a regular database. It buys facts in different ways, it is connected in blocks. Any new facts that come to light are stored in a shiny block. Blockchain can be complicated, but the center is simple.

Blockchain technology is really a revolution. Platforms like Ethereum have shown the power of blockchain much beyond cryptocurrencies.

Blockchain technology is most easily defined as a decentralized distributed ledger that records the emergence of digital assets. In this design no one cannot modify blockchain data which makes it a legitimate and used for some important sectors like industries such as finance, cybersecurity, and healthcare etc.
