An Elementary Explanation Of How Bitcoin Works

 An Elementary Explanation Of How Bitcoin Works

To most people, Bitcoin can seem like a financial concept made in a parallel universe. Yes, it’s a very complex and complicated concept, but it doesn’t mean it’s impossible to learn it. When you think about it, many people started off with no idea about bitcoins and how it worked. But look at them now, they’re probably investing left and right in various cryptocurrencies like pros and possibly profiting very nicely as well! So, in this article, we’ll try to simplify how Bitcoin works using a betting game analogy:

Imagine playing a betting game with your friends, but none of you have any money on hand, so you decide to use a ledger to record the transactions, like your winnings and losses. But you don’t want to put your trust on one friend to record everything, so a lot of you decide to make a ledger simultaneously.

This way, at the end of each game, those who kept ledgers can compare their records to see if it all evens out—which means that cheating the system would be virtually impossible unless everybody else is in cahoots with you, which ultimately defeats the purpose of cheating in the first place.

The ledger is not hidden or exclusive to the ledger keepers; you can view it anytime you want. To add your transactions to the ledger, all you have to do is broadcast your transactions to the ledger keepers, and you pay as little or as much as you want to make sure they put your name down on that ledger as soon as possible.

Your friends who keep the ledgers up to date get compensation for their hard work with a reward in the form of money. This money comes from an external source—say, a vault with a limited amount of money. The money in the vault wasn’t part of the money circulating in the betting pool, but it became so once it was acquired by your ledger-keeper friends.

This simple analogy is exactly how Bitcoin operates, albeit on a much more complicated level. Bitcoin runs on a global computer network, and each transaction is compiled into new blocks which are then connected to the last block on the blockchain. And the bitcoin miners are the ledger-keepers who work hard to record transactions and mine those precious bitcoins.

5 Interesting Facts About Blockchain Technology

 5 Interesting Facts About Blockchain Technology

Blockchain is the technology that makes Bitcoin and other cryptocurrencies very secure. It’s an open-source and distributed database that is stored in nodes or computers within the network.  When new transactions or blocks are added to the blockchain, it will automatically update itself. Here are 5 very interesting facts about this ultra-modern technology.

1 – It’s Tamper-Proof


Once an entry has been added onto the blockchain, it will be nearly impossible to remove or alter it later. If you want to alter an entry, you’d have to basically alter all the transactions that came after it. Doing this is mathematically impossible, so even genius fraudsters would have to look elsewhere to steal bitcoins without too much effort. Being tamper-proof is also the reason bitcoin payments are final and irreversible.

2 – It’s 100% Transparent

Anyone with access to the blockchain can see all the transactions that have ever occurred in the past. You can even look up the first ever block (block 0) that was mined by Bitcoin founder, Satoshi Nakamoto, in 2009. This genesis block contained the message “The Times 03/Jan/2009 Chancellor on brink of second bailout for banks.”

3 – Criminals Can’t Hide Behind The Blockchain

If criminals think they can hide behind the relative anonymity that Bitcoin provides, they’re sorely mistaken. Many have tried to evade the long arm of the law by converting their stolen loot to bitcoins and transferring them to different wallets, but with the transparent nature of the blockchain, computer experts can spot and trace all the bitcoin transactions these criminals have ever done.

4 – Blockchain Technology Is Not Limited To Cryptocurrencies


Many different startups have started to experiment with implementing blockchain technology in various industries. Once such example is Ethereum with their smart contracts technology which basically runs on blockchain. Since the blockchain is decentralized, two parties can make transactions between themselves without needing the services of a middleman. This not only saves you money, but it also saves you a lot of time and conflict.


5 – Blockchain Can Still Be Improved


While this technology has definitely improved the lives of many people, it can still be improved. For one, as time passes by, the blockchain will grow to be several hundred gigabytes of data. This will cause a lot of bandwidth and storage problems on personal computers. Let’s hope the brightest minds in the crypto space can find a solution to this predicament soon.
