What is Bitcoin and how it works?

"Bitcoin is cash in the cloud"

You can send bitcoins via the Internet directly to anyone without intermediaries. Like cash, Bitcoin transactions are irreversible. The bitcoin is used worldwide and in all languages.

What is Bitcoin?

Bitcoin is primarily 3 things, a digital currency, a decentralized network that are transmitted bitcoins and finally and most important the blockchain, a decentralized ledger where all the transactions are written.

The network consists of all bitcoin nodes, and each contain a copy of the blockchain. This allows the network to be 100% decentralized since the same information is present everywhere.

Bitcoin, as technology is the first network of decentralized consensus, for which all individuals participating in it can rely on the outcome of a transaction without necessarily knowing the person with whom you are exchanging something. This solves the famous problem of Byzantine generals who aim to coordinate an attack but do not trust the messengers who have to communicate orders.

How does it work?

To use bitcoin the first thing you need to do is have a wallet to store them and with which you can transfer to others. You can create one here or use the one provided to you by

A transaction in the bitcoin network starts when a person send from his wallet a defined amount of bitcoins to another.
Typically a transaction in the bitcoin network is instantly visible, it takes about 10 minutes to an hour to spread and have all the necessary confirmations to not be rejected by the rest of the network.

The architecture of the bitcoin network itself requires a minimum of 6 confirmations of network nodes to mark a transaction as valid.

Once the transaction begins to travel on the bitcoin network, the work the nodes do is to confirm that the transaction attributes are valid and do not belong to an already issued transaction, thus avoiding the occurrence of double spending thereof. This distributed consensus makes the distributed nature of the network very efficient to avoid fakes or scams.

Each transaction has a cost of 0.0001 Bitcoin which is distributed among all network nodes working to confirm each transaction.

In addition to the work of confirming transactions, network nodes, also known as miners are responsible for generating new bitcoins that they will be turned over to the network every 10 minutes. The issuing policy is predefined in the bitcoin protocol and says that each miner will be awarded a certain amount of bitcoins, which will be reduced by half to 4 years to reach 21 million Bitcoins which is the total in circulation find.

Currently the reward is 25 new bitcoins in 2017 will be reduced to 12.5 Bitcoins and so on every 4 years to reach the total of bitcoins issued.
