#2The Minimum Viable Blockchain (https://www.igvita.com/2014/05/05/minimum-viable-block-chain...) is by far the best introduction to blockchain I have read.

I keep forgetting this exists. The video is damn good at explaining how blockchain overall. I think the strongest bit, is showing how data manipulation is easily detectable.

This is a great video/site. After watching this, it made me think how amazing the blockchain would be if our accounting and trading systems were built on top of it. As a programmer outside the financial services sector, it seems to me something like this has to be the future. But it would be really interesting to see what quants and others in the field think.

wow. That Anders video is definitely the best description/explanation of blockchain I've ever seen.

#7One thing that bothers me about all blockchain demos or tutorials is that they work on the concept of tracking outputs of transactions rather than just maintaining state.

Back in 2008 I invented an algorithm for tree structures where the definition of the hash of any node, was "the hash of hashes of all its immediate children". I had invented a way to do 'tree node comparisons' where any time two tree nodes on a tree had the same 'hash' i knew the content (recursively deep into the tree) of those nodes was identical. I never went forward on that algorithm, because i knew it meant each time a tree node was modified, the hash of all it's parents (i.e. path to root), had to be recalculate. But I had explained it to several developers who were all amazed by it. It now realize I had invented blockchain. I am pretty sure i'm not the first one to realize hashing actual hashes (in a recursive or chained way) is a powerful concept. I may add this to my current project SubNode (sbnode.com), and I could pivot that app into a blockchain technology!

I think Merkle got there first, in about 1979 or so.

It's a nice strike against software patents though, probably every programmer interested in data structures goes through a whole series of these independent inventions.
To award a patent to someone just because they thought of it first is ridiculous.
