I like the intro, very clear! I also like the narrative cross-referencing the docs, which people will sooner or later need to do as well. I have to admit that I only glanced over the code. This caught my attention: "In the EndPoint specification, it demands the "BE encoded 4-byte" address, which is exactly what's outputted by self.address.packed." Does this mean that Ethereum only supports IPv4? I searched around and…

documentation says it all:

"bytes address; // BE encoded 4-byte or 16-byte address (size determines ipv4 vs ipv6)"[0]

Though I meet the criteria as stated (knowledge level wise - I'm a retired IT Exec/long time geek), yet this still is a bit too esoteric for me.

As one of the 'killer apps' for ethereum is smart contracts, I'd like to see this explained in a 'for dummies' high level way, then decomposed into the finer technical chunks needed to make it happen.

Earlier quoted context omitted.

Except any reasonably complex interactions between parties which may or may not be accounting applications yet still need a distributed system of trust. Which includes a few trillion dollar industries.

Registered assets are always more secure and cheaper than bearer assets. And if you needed bearer assets, there's multisig, which does everything turing complete code does, cheaper and more secure

Its the interactions between assets, agreements and trusted devices which opens up possibilities greater than the scope of this thinking.

Java Magazine published an article on Ethereum, explaining how it works, and how to access from Java [1]

There are no uses for turing complete smart contracts on a blockchain

Of course, us maximalists all know Bitcoin is the pinnacle and can never be improved on. /s
