A major concern now is to make sure that our files are secure and that no one can change said file and claim that their address has more Cryptocurrencies (Bitcoin, Ethereum, Litecoin etc.) than in reality they own.
This is where “mining” comes into effect as one solution. bitcoin blackjack
Basically, we have a network that sends the file to tens of thousands of “rubber stampers” that can sign off on the authenticity of the transaction therefore checking that everything is genuine and validating the transfer. Resulting in the sender being able to spend his Bitcoin and ultimately you being able to receive it without concern.
Now, here is where human nature kicks in, we have to compensate people (or miners) for their time and effort for verifying all these transactions (there is also an energy cost to take into account) After all why not share amongst us all, and this leads us to “Bitcoin miners”.
Did you see my comment above, “After all why not share amongst us all”, welcome to the 21st century and the world of cryptocurrencies! After all we are cutting out the middle man (bankers and ultimately the government) So the “miners” get compensated with Bitcoins through the blockchain to make sure that all the transactions are genuine, therefore there is no middle man manipulating the currency in between the transaction, how’s that for an amazing deal?
So now you have a decentralized currency (no government manipulation or interference and this is what is important) being watched over by thousands of miners, who admittedly do receive a small fee, but are checking the validity and honesty of all these transactions.
That is money for the 21st century and beyond.
Now, transactions are covered, but where do I store my Bitcoins?
This is where the wallet comes in.
Simply put, you have a unique bitcoin code, this code can be used to send bitcoins to you therefore can be seen by anyone and is visible in order for you to transact across the bitcoin environment.
