Technology, that may appear to be a breakthrough, most probably like the Internet dissemination in the 80’s.
Blockchain allows any digital information to be distributed in a secure way to the other business parties. It can not be copied or changed. Its value and origin can be easily confirmed in real-time by the other network elements (devices). So in case one of the network elements is hacked (speaking about frauds), the other element will give a signal : “hey, we have another value for this particular event”. This gives grounds for the new security of the transactions and information distribution. This is based on network elements with no need for any third party organization to watch the security of transaction or information flow. Like with the banks today, who secure the e.g. money transfer transactions between payer and receiver. This can be watched with network elements in Blockchain, and traditional bank activity is not required any more.
Not only speaking about financial transactions, but digital information distribution in general, this makes in fact the grounds for the new type of internet. What is more, like with the traditional internet we have today, iPhones, cars… we do not need to know how they are built and how they work. We just use them. The same will happen with Blockchain.
