When I announced I was going to do a quick article on this subject, several people said it confused them. After completing the article, I feel it really shouldn’t. Regardless, on editing, I have kept this article concise and without too much waffle. If anyone has questions, please ask, it helps me dig deeper and I am happy to assist where I can.
Bitcoin is a crypto currency, which just means it is digital money.
The value is not assigned by bank or government, but rather from the users, that being the seller and buyer.
But before you panic, no money really has any value. For this reason, there really is no difference between Bitcoin and the Pound, or Dollar, or Rand. Values are attributed by an authority.
Okay, so how does it work?
A normal process:
The above sounds simple, and it is!
The process is made possible as follows:
Digital wallets on everyone’s device have copy of Bitcoin Ledger, which is basically a record of every single transaction… ever. But this is an example of it in simplicity:
A lot of people are going to confuse you, but the basic idea is, the ledger knows how much money is in the system, and to whom it is assigned at the time. So the system is in fact not offering a bank statement balance, but rather it verifies the path of the money in the system.
The path of the money in the system.
A similar concept to using a web browser, and you clicking the go back button:
Except, you can go back since the inception.
This is the beauty and the safety of the system. Like web pages, there is an address, which links to a place on the internet, and the browser moves you from place to place, and at the end and last part of each address and place link, hidden in the code on the browser, there is a string of information. If you clear your history, or type in something out of place in the browser, it becomes impossible to go back. Therefore, the concept and process of Bitcoin, although technically not the same, you will understand if you press the back page button, and it takes you to the wrong page, you know something has changed or gone wrong – and that is the same concept as Bitcoin… which both has a record (string of information) of the past, and a process for future transactions.
This is what confuses people. If I can explain it as follows.
There are 100 apples in the world.
There are 1000 people in the world.
But who has what apples? How many? And when?
We know that Susan or Bob just traded.
So we can see through the open book system that Susan sold an apple. We can see the apple is now with Bob.
The system knows Bob has it. It’s a transparent system. Every single person on the system, has a copy of that transaction.
Therefore, at any time, anyone can see, Bob had the apple AFTER Susan.
Which means, he is allowed to trade THAT apple. He cannot trade two apples, and he cannot grow a new apple.
Because he only has one?
In the system, you cannot have more than you were given. Not ever.
So, we can confirm, Bob has one Apple only.
Therefore, Bob has one apple to trade, not two, not ten, Bob has 1 apple.
Total transparency of the apples. Power to the People. Know where your apple came from!
Let me emphasize:
No one can add an apple to the system, why? There are only 100 apples. There will never be more than 100 apples. Of course, in this explanation, I am referring to a product, as the Bitcoin.
Apples make people understand for some reason, so I use the word apple a lot.
The currency Bitcoin protects itself, it records and shares two things.
Then, it uses a clever block system, which adds “time” to the entire process, to ensure that there are no duplicate trades, or purchase when funds are not available. This adds security, and also solves the problem caused by the multiple computers around the word in the network, which would obviously create a time delay.
Let’s talk about these computers, and the users of the computers, which are called Miners.
This is where I get very excited. You might not, but it is for me.
So, when Bob and Susan decided they wanted to trade an apple, and because they want to use Bitcoin system to trade for the apple and pay, they had to announce the transaction to the entire network. Not to one person, but absolutely every single user of the entire currency!
Now, some of these users, sit at a computer, and are called Miners.
When a transaction is announced as a pending trade, and the system transaction code / key is processed, there is this virtual race by all these participating computers around the world, to try and verify the transaction. This is simply done through guessing! Yes, Guessing. The total number of transaction keys in the system are over 7 million trillion. Now that’s a lot, and this is the variable per transaction! Remember, the key is basically where the money is coming from and going to. That’s all. But, the key is also linked to the transactions prior, and all the transactions in the future. A lot of transactions happen at the same time, and to add some sort of order to the ledger, someone has to put the transactions in an order, thus helping the universal ledger makes sense.
That is exactly what a Miner does.
So, transaction is announced, all the transactions are sitting there, and the Minors try solve a random guess to decide which transaction is processed first, and then added to the log and therefore ledger and creating a successful safe transaction. Remember, this transaction is added to the “history” of Bitcoin transactions, and will link and backdate since its inception.
So, if the Miner guesses the answer correctly, he or she is awarded with some bitcoins, which is how the Bitcoins enter the system! Genius.
In order to beat the system, or hack the system you are up against every single Miner.
To fix the fundamental flaw of the block chain file size, centralization of the file through super nodes might need to happen, and this will be similar to branches of a bank, so we will again have in authorities in terms of bitcoin bank branches. There is however no stable long term solution finalized. I really do not know who is going to fix this.
The currency, as designed now, with a set limit to the amount of coins, and given over time more users, some of which will lose funds, will result in less money over more people. 21 million, multiplied by 100 million is all that there could ever be to trade with. That with a World population of 7 billion is not very much money.
Security is an ongoing concern with the internet. I don’t know who at Bitcoin is going to tackle this, because, the program creator disappeared some time back. At the time this article was written, June 2017, there were nearly 21 million transactions done to date. The main vulnerability and attacks appear to link direct with user fault and those companies who manage stock larger amount of funds, for example bitcoin firms.
I read an article that said that currently it is estimated 10% to 20% of all Bitcoins in existence are held by criminals. Again, is this need to panic? No…. think about how many non-digital criminals are sitting with funds… and how much larger that % must be.
My only advice would be and based on my research, and the processing time it takes, and some other complicated things, is that if you are physically offered a product, wait 70 minutes before you release the product.
Another challenge, out of everyone’s control, Bitcoin users are going to have to work on how to exchange their currency for other normal currencies. While there are actual vendors and machines you can use to buy Bitcoin, there is nowhere really to buy other currencies using Bitcoins.
Also, while peer to peer, and peer to Bitcoin traders remains anonymous, or has a level of anonymity, when you need to use your standard currency in your country to purchase Bitcoin you have to follow the local rules and legislation, and that often requires giving more information than you might wish to the authorities.
