Interview on Brett King’s Breaking Banks

I was honoured to be invited to Brett King’s Breaking Banks podcast to talk about Bitcoins and blockchains with an Asia angle in the “BITCOIN & BLOCKCHAIN IN ASEAN” episode.

Rob Findlay, CEO and founder of Next Money (formerly Next Bank) hosted the conversation, and Marcus Swanepoel, CEO of BitX also shared his insights.

The full audio episode is here and I recommend subscribing to the podcast if you are in to FinTech.  A transcript of the relevant section is below, edited for clarity:

Just because it’s on a blockchain it doesn’t mean it’s true

This short article attempts to explain what people mean when they are talking about blockchains being a “single source of truth”. In classic Chinese Whispers style, the narrative has become confused about what is meant by “truth”.

This is currently relevant to discussions in the insurance industry where blockchain enthusiasts may be eager to promote blockchains as a solution to the problem of verifying if something has happened or not.

Here, I permanently recorded on Bitcoin’s blockchain a non-truth about the world.

Confused by blockchains? Revolution vs Evolution

Cryptocurrencies vs Industry Workflow Tools

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.
Cryptocurrencies vs Industry Workflow Tools

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).

A gentle introduction to immutability of blockchains

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 a nutshell: Eris (Epicenter Bitcoin interview – Jan 2016)

I enjoyed listening to episode 112 of the podcast “Epicenter Bitcoin” where Casey Kuhlman, CEO of Eris Industries was interviewed. Here are my notes on parts that I found particularly interesting. Misunderstandings and paraphrasing errors are mine.

If this is hard to follow, it may be helpful to read my introductions to blockchains, bitcoin, digital tokens, and smart contracts first.

Inside Bitcoin’s blockchain

I’m often asked what’s in a blockchain, so I put this infographic together as an aide memoire using bitcoin’s blockchain as the example.

Although other blockchains will have differences, the overall structures should be similar.

A gentle introduction to bitcoin

This article is a gentle introduction to bitcoin and assumes minimal technical knowledge.

Shorter companion pieces to this are:

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.
