I know. That still doesn't change the fact that BitCoin is an economically non-viable technology that will never grow out of its niche (unless it undergoes a mammoth change). Maybe another cryptocurrency will fill that roll eventually but then it will sacrifice security for the sake of convenience and speed which is no better than the current credit card networks. The blockchain, however, will gain some traction if used in 1st or 3rd party trusted networks; kind of how escrow accounts are used now.

You considering it non-viable does not change the fact that 2% of Americans own it

Given the way fiat-currencies are being devalued around the world, a currency that cannot be manipulated by politicians might be.. interesting
As for bubbles go; it seems that more people own stocks than BC. One of the two still has room for growth.

Since there are often "two sets of books", will there also be 2 blockchains?

The ledger is distributed so you could theoretically have a million set of books but you need to shrink that down if you want to make money off of blockchain. My idea was to start up a "Blockchain Federation" of companies to offer Blockchain as a Service. The federation could maintain any number of discrete blockchains for any kind of business relationship and their network would act as the distributed ledger. This way you don't have to share your ledger with the entire world but you still get the benefit of blockchain's robust, decentralized nature. There's no way I could afford to build it so I posted the idea here.

Reading this book about Blockchain technologies and it is convincing me that blockchain is a juggernaut (unstoppable).
Blockchain: A Practical Guide to Developing Business, Law, and Technology Solutions [^]
It really is going to be used everywhere (identity, finance, healthcare, file storage/sharing, supply chain).
If you check out Hyperledger Projects - Hyperledger[^] you will see that there are major blockchain projects being backed by major corps (SawTooth = Intel, Fabric = IBM)
And everyone has heard of Bitcoin but Ripple (Company - Learn About Ripple)[^] is getting huge and backed by large corps.
A nice summary of the technology:
Blockchain book said: Simply put, a blockchain is a database encompassing a physical chain of fixed-length blocks that include 1 to N transactions, where each transaction added to a new block is validated and then inserted into the block.
The concepts behind the blockchain really are interesting.

Yeah, a lot of things are that. I always go into reading about new tech with a critical eye toward it.
The foundation of it is quite interesting though because it is such a novel idea of a hash tree (merkle tree) that insures that each node is valid (and then all data must be valid). The concept is quite interesting.

I very much agree. While the tech itself looks promising, everybody and their grandma try to shoehorn blockchain into everything, no matter how it fits. And let's be frank, with all the issues surrounding Bitcoin, we have a better precedent on blockchain having issues than on blockchain solving them.

Yes, already sat through a presentation on BC with an offer to help me set up my first BC (for a fee of course). When I saw the word "trust" I ran.

BC doesn't require trust; it is not fiat.

While I really like the idea of blockchain I do think it's being hyped a lot.
Sure, some bigger companies are hopping on the hype train, but I don't see a lot of value for regular businesses.
It's not as secure as they make you believe.
BitCoin (and blockchain) can be hacked or tampered with or whatever it is they do.
More importantly, it's really expensive to generate those hashes (or nonces to be precise)!
The fact that mining them can make you money says enough.
It's like saying "we need ID's for our database, let's ask consumers to rent us their computers so we can get those ID's!"
Not going to happen for about 99.999999% of the businesses.
Maybe I just don't know blockchain well enough, but I know a lot of people talking about blockchain, but no one who's actually doing it.

I believe you may be misinformed. Bitcoin maybe. Not sure if something happened there. But do you know that each node in the blockchain has a SHA-256 hash of the next node, etc? Quite difficult to hack.
There is a time-based part to the value also and then the decentralized check that goes on.
So not sure if you've just heard it was less secure or something. You'd have to bring more facts to this story that it is insecure than just that it's not as secure as they say. I'm not sure either though, but if you read the part of how a blockchain is a merkle tree you would probably agree it would be quite difficult to alter the data.
But I do understand that nascent tech (and especially overhyped nascent tech like blockchain) often makes people think it is just a bunch of noise. Maybe it is, but the details behind it are very interesting.

While it is true that hacking a SHA-256 is practically impossible, the problem with blockchain is elsewhere:
1. The HASH at any node is the combined HASH of all the nodes below it, all the way down... It makes the HASH creation a time and computation consuming when the blockchain (tree) grow...
2. The second security measure of a blockchain structure is distribution. You can not temper with the chain at one position, as the other instances will refuse to that... But that immediately rises the problem of the owner of the chain... Let take a bank - it moves to blockchain, but - obviously - all the instances will be owned by the bank, so that can give larger security against attacks from the outside, but can be hacked still from the inside... Not to mention a blockchain owned by a private company to store your data...

Unless you flood the network with bad actors. I guess it's fortunate we don't have massive countries like China and Russia with masses of resources and an active interest in disrupting such a thing. I mean when blockchain runs everything, even American government systems, thank God there are no Chinas or Russias.
People saying blockchain is "secure" is like people saying Apple Macs are secure. They're not, it's just that no-one has the motivation to attack them. Yet.
