I'm a man with a love of writing and reading, I've got a passion for novels, movies, politics, social.


What is Bitcoin?

Bitcoin is a cryptocurrency, invented by Satoshi Nakamoto in the form of open source software since 2009. Bitcoin can be exchanged directly using an Internet-connected device without going through a central financial institution. which time.

Bitcoin works differently from typical currencies: There is no central bank to manage it, and the system is based on a peer-to-peer network protocol on the Internet. Bitcoin supply is automatic, limited, distributed on a predetermined schedule based on algorithms. Bitcoins are issued to computers that "mine" Bitcoin to pay for verifying Bitcoin transactions and writing them into a distributed ledger in a peer-to-peer network - known as the blockchain. This ledger uses Bitcoin as the unit of account. Each bitcoin can be broken down to 100 million smaller units called satoshi. (source: wiki)


Transaction fees may apply to new transactions depending on network resources. In addition to transaction fees, miners are also paid for creating blocks that contain transaction logs. Every 10 minutes, a new block is created with an allocated amount of Bitcoin. The number of bitcoins allocated per block depends on the uptime of the network. In July 2016, 12.5 bitcoins were allocated for each new block. The inflation rate will halve to 6.25 bitcoins by July 2020 and continue to halve every 4 years until a total of 21 million Bitcoins are released in 2140. In addition to Bitcoin mining, users can obtain Bitcoins by exchanging them for Bitcoins when selling other currency, goods, or services.

Bitcoin is the most typical, firstborn, and most widely used cryptocurrency in e-commerce. Businesses tend to want to pay with Bitcoin to minimize costs. Large fluctuations in the value of each bitcoin have prompted criticism of Bitcoin's economic suitability as a currency.


To make it easier to visualize, we have an example like this about Bitcoin:

Imagine you and I are sitting in a park. I have an apple, and I give it to you. So you have an apple, and I don't have any. I can no longer control that apple, and you have full control over it. We also don't need a 3rd person there to help us with the transaction. We don't have to bring Uncle Tommy over just to sit with us and confirm the apple has passed from my hand to yours. That's how in-person transactions happen.

And now let's turn that apple into a digital apple. I still give you my apple, but it will take a few more steps.

How do I know this digital apple used to be mine and is now yours, and I can't interfere. How do I know I didn't send this apple to Lisa or Joe as an attachment in a previous email. Maybe I copied it into thousands of apples before I sent it to you or I even posted it on the internet and millions of people could download it.

So we need a ledger to record all the behavior of the digital apple. That's why blockchain was born with digital apples as bitcoin. And miners are the ones who operate this ledger.


Advantages of Bitcoin

Disadvantages of Bitcoin
