This means point is, everything is open, transparent, and trackable, but you still can’t tell who sent what to whom. Let’s explain this with an example. You can see on your screen certain rows from the bitcoins ledger, We can see that a certain bitcoin address sent 10,000 bitcoins to another bitcoin address in May of 2010. This specific transaction is the first purchase that was ever made with Bitcoin, and it was used to buy two pizzas by a guy named Laszlo Laszlo published a post back in 2010, requesting somebody to sell him two pizzas in return for 10,000 Bitcoins. Well, someone did, and now the price of these two pizzas is worth well over $100 million today. Bitcoin is also decentralized, there’s no one computer that holds the ledger. With Bitcoin, Every computer that system is also keeping a copy of the ledger, also known as the last thing. So if you want to take down the system or half ledger, you’ll have to take down 1000s of computers that are copied and constantly updating it, most money today, Bitcoin is also digital. This means there’s nothing physical that you can touch in Bitcoin, there are no actual coins. There are only real ones and balances. When you own Bitcoin, it means that you own it to access a specific Bitcoin record in the ledger and send funds from it to a different. So, what is it, why is it such big news? Well, for the first time since digital money came into existence, we have an alternative to the current system. Bitcoin can not be controlled by any government or bank. Think about the time before the internet, how centralized the flow of information was, basically, if you wanted information from like the New York Times, The Washington Post.
