This article attempts to explain the difference between the revolutionary disruptive innovation of bitcoin and the evolutionary efficiency innovations of industry workflow tools, and why calling them both “blockchains”, even as a generic term, is incredibly confusing.
For the rest of this post, I will use the phrase “industry workflow tools” instead of industry blockchains, as some of the emerging solutions being proposed in this space are not blockchains (eg, R3’s Corda is not a blockchain but Digital Asset’s solutions are – however, both companies are proposing industry workflow tools).
In the context of data security, the immutability of data stored on blockchains is important. What do people mean when they say “Blockchains are immutable”? In this post I try to explain the key concepts.
It may be useful to read introductions to blockchains and Bitcoin if you have just arrived here or are unfamiliar with them.
In the popular media, you will often read comments like “Bitcoins are stored in a digital wallet”, or “You can send money using blockchain technology”. These comments can be misleading and can confuse. By the end of this you should understand enough to participate in a dinnertime conversation about bitcoin, and not be mystified by the topic.
