Anyone investing in an online currency like Bitcoin today almost certainly knows what blockchain is, because it plays such a large part in making transfers of that currency secure. In the past, moving money meant going through a third party or an intermediary, and all sorts of unexpected things could happen along the way — some good, some not. With a blockchain, those worries largely go away. So this article is for everyone interested in Bitcoin and blockchain who wants to understand why the two belong together.
If you have an interest in online commerce, this is a currency worth studying, because buying and selling online in future may well use it directly as the medium of exchange. Fortunately we have blockchain to cut out the intermediary without making the system unmanageably complicated, and it adds confidence in the currency's security — the reassurance of having a good online wallet, such as a Ledger, TREZOR or KeepKey hardware wallet, so there is no need to fear the various kinds of fraud out there.
To close: for anyone still looking into this, or still unclear how the two terms actually connect, I hope at least that reading this makes clear why you need this system to look after your Bitcoin as you transact online — more easily, more conveniently, and with a good deal more security.
