Bitcoin and Blockchain
The bitcoin goes through a technology called blockchain, for those who do not know about the topic of blockchain and security is that the records and transactions that are recorded in this database can not be modified and can be tracked by the rest of life, for this the network has nodes in which the information is saved and replicated, anyone can create their own node by downloading the whole network and having a copy of it, there are also the miners who take that information from the transactions that are done in a period of 10 minutes, take the algorithm, or the code, or the hash that allows to validate the transactions that are inside a code, and once that happens that miner begins to spread to the network through the nodes the information of what he did to verify those transactions.
This information begins to move node by node and the network say that it begins to spread, at this moment there are so many nodes worldwide that in the next 10 minutes not necessarily all have to have the same information but if a new one is generated block this sticks to the longest chain, it can happen that two miners validate at the same time a code or a block, that's because there are many more computers undermining is more much more hashrate capacity that is trying to discover those codes or those hashs to be able to mine the block, this has no danger, it is not a fork, just once the network randomly chooses one of the two chains the next block is going to stick to the longest chain then and they will be invalidated the others that will return to the mem pool.
In the past nine months the bitcoin only fallen in price but increased usability and number of transactions, means that adoption if it is rising very important to begin to understand that revolution is technology or blockchain more than the value of cryptocurrencies.
