Smilevictorobinnahttps://bitcointalk.org/index.php?topic=5498665.0A lot of newbies that are very eager to know about Bitcoin, you can carefully read all I have written it will help you in this Bitcoin journey you are about to start.
Bitcoin was created by Satoshi Nakamoto.
What is Bitcoin.
An agreement amongst a community of people to use 21 million secure mathematical tokens--"bitcoins"--as money, like traditional African and Asian societies used the money cowry. Unlike the money cowry:
there will never be more bitcoins
they are impossible to counterfeit
they can be divided into as small of pieces as you want,
and they can be transferred instantly across great distances via a digital connection such as the internet.
This is accomplished by the use of powerful cryptography many times stronger than that used by banks. Instead of simply being "sent" coins have to be cryptographically signed over from one entity to another, essentially putting a lock and key on each token so that bitcoins can be securely backed up in multiple places, and so that copying doesn't increase the amount you own.
Because bitcoins are given their value by the community, they don't need to be accepted by anyone else or backed by any authority to succeed. They are like a local currency except much, much more effective and local to the whole world. As an example of how effective the community is at "backing" the bitcoin: on April 4th 2011 30,000 bitcoins were abruptly sold on the largest Bitcoin exchange, consuming nearly all "buy" offers on the order book and dropping the price by nearly 1/3. But within a couple of days, the price on the exchange had fully rebounded and bitcoins were again trading at good volumes, with large "buy" offers slowly replacing the ones consumed by the trades. The ability of such a small economy (there were only 5 million out of the total 21 million bitcoins circulating then, or about 3.75 million USD worth at then-current exchange rates) to absorb such a large sell-off without crashing shows that bitcoins were already working beautifully.
Problem Bitcoin solves.
Mathematically, the specific implementation of the bitcoin protocol solves the problem of "how to do all of the above without trusting anyone". If that sounds amazing, it should! Normally a local currency has to trust all kinds of people for it to be able to work. So does a national currency. And in both cases, that trust is often abused. But with Bitcoin, there's no one person who can abuse the system. Nobody can print more money, nobody can re-use the coins simply by making a copy, and nobody can use anyone else's coins without having direct access to their keys. People who break its mathematical "rules" simply end up creating a whole different system incompatible with the first. As long as these rules are followed by someone, the only way Bitcoin can fail is for everyone to stop using it.
This marvelous quality of not having to trust anyone is achieved in two ways. First, through the use of cutting-edge cryptography. Cryptography ensures that only the owner of the bitcoins has the authority to spend them. The cryptography used in Bitcoin is so strong that all the world's online banking would be compromised before Bitcoin would be, and it can even be upgraded if that were to start to happen. It's like if each banknote in your pocket had a 100-digit combination lock on it that couldn't be removed without destroying the bill itself. Bitcoin is that secure.
But the second way of securing the system, called the blockchain, is where the real magic happens. The blockchain is a single, authoritative record of confirmed transactions which is stored on the peer to peer Bitcoin network. Even with top-notch digital encryption, if there was no central registry to show that certain bitcoins had already been "paid" to someone else, you could sign over the same coins to multiple people in what's called a double-spend attack, like writing cheques for more money than you have in your account. Normally this is prevented by a central authority, the bank, who keeps track of all the cheques you write and makes sure they don't exceed the amount of money you have. Even so, most people won't accept a cheque from you unless they really trust you, and the bank has to spend a lot of money physically protecting those central records, whether they are kept in a physical or digital form. Not to mention, sometimes a bank employee can abuse their position of trust. And, in traditional banking, the bank itself doesn't have to follow the rules you do--it can lend out more money than it actually has.
The blockchain fixes all these problems by creating a single master registry of the already-cryptographically-secured bitcoin transfers, verifying them and locking them down in a highly competitive market called mining. In return for this critical role, the Bitcoin community rewards miners with a set amount of bitcoins per block, taken from the original limited quantity on a pre-agreed schedule. As that original amount gradually runs out, this reward will be replaced by fees paid to prioritise one transaction over another--again in a highly competitive market to ensure the lowest possible cost. The transactions are verified and locked in by the computational work of mining in a very special way so that no one else can change the official record of transactions without doing more computational work than the cumulative work of all miners across the whole network.
I believe this write up has helped you in one way or the other as a newbie.
Please I'm open for correction and you can add also in other for us to achieve this goal of educating the newbies.
Thank you.
