+Bitcoin was invented in 2008[2]. It is primary function was to be an online currency, which could be paid with over the internet.
+With a boom of it's price people started to treat it like a commodity. And it's creation started a cryptocurrency era which then spawned in great numbers.
+Many had different mechanisms, some of them can be considered to be technically improved, some enhanced, some of them are out of technical point of view 
+downright worse. To name a few: Etherium, Monero, Dogecoin.
+
+There are many instances of reason that gave an opportunity to it's rise that allowed it to be globally somehow adopted.
+I believe that many of these instances are connected to technical solutions that Bitcoin offers. It gives it's 
+users a few, whoever stone carved advantages over clasic currencies. Some of them being certain degree
+of annonymity or assurance that there will never exist more than 23 000 000 units (which I will further on refer to as bitcoins[1]).
+This means there will be no problem with inflation, on the other hand there is a deflation. It allows it's users to pay worldwide without a third person.
+Bitcoin is created to be distributed[2] which makes it to a certain degree uncontrolable by anyone, unless he has at his disposal more than half
+of all computing power that surges through Bitcoin (this is called 51% attack[2]). For each transaction there is a certain everchanging fee. That is reaped by a miner who
+mines the block with the transaction on it. One of cryptographical foundation that Bitcoin is build upon is a Blockchain which is a vital
+part in how the currency circulates between wallets and users. It's technical background is secured by cryptography and math.
+
+What it means that miner mined a block? It means that he was lucky and his part of computing power achieved generating a new block out
+of hash of the previous block (his parent) and things it found on the internet, computed or guessed. And afterwards was the
+It consists of large quantity of blocks of information, which are bound together not unlike a linked list. Each block holds an
+information that can be used to assert it's parrent. A very first block was mined by Bitcoin's creator Satoshi Nakamoto[1], it is
+called Genesis block. This block holds no such information.
+Information on these blocks consists of mostly transactions and movements of bitcoins across the blocks as well as an amount of newly
+mined bitcoins, which could be further decoded into new addresses which the successful miner generated and to which he presumably
+holds a secret that could be imagined as a ticket to access these 'coins'.
+
+The amount of mined bitcoins is not static. It is continuously decreesed by half of the amount in a process called Halving until
+there will be none bitcoin mined. And the blocks will be created purely for transactions and fees they bring to the miner.
+Therefore there will be constantly a decreesing amount which will be increasing total amount of bitcoins up to 21 000 000.
+(times 100 000 000 satoshi). This all is achieved by clever usage of hash functions. 
+The more different miners participate in the mining and the more evenly is computing power distributed among them, the lower is the chance
+that someone is able to get lucky first and then create another block many times in a row. Chances are rising exponentially with each block.
+(assuming that chance to mine a block is equal to one's mining share on global stage)
+
+Before the transaction is agreed upon by general majority of miners and is approved and permamently written on Blockchain, it needs to be validated.
+Transactions are hashed in a Merkle Tree[1], which significantly saves the ammount of previous hashes needed to validate a block.
+Inside of bitcoin wallet are no coins, there are tickets to move coins on Blockchain down the chain. Whoever holds a ticket is authorized to pay with
+the coins or move them to a another wallet and much more. Transactions are going to be of a great interest to us in this list we will be looking at
+mosty Partially Signed Bitcoin Transactions which we will be finalizing under certain cirmcumstances.
