It simply means that there are code examples to follow. Do you know about the tech behind blockchain? Merkle trees? Quite interesting. How might they be used. That's the interesting part. And seeing how the BC is implemented on top of that. Quite interesting.

I agree, it is quite interesting. If it is to be a tech juggernaut the world may need a couple dozen reactors and some tons of uranium. I hear implementation gobbles electricity like Joey Chestnut eats hot dogs.

True the weakness is in other systems as well , but the point is that having a more supposedly 'secure' system is irrelevant if there are other weaker links! Plus the big downside of Blockchain on a large scale is the sheer cost of all those transactions in monetary as well as infrastructure and environmental costs. Without some other technology break through Blockchains are going to be problematic for most applications.

It's not; you don't use an unlocked door instead of a locked door simply because your spouse is a "weak link".

Monetary costs? Which, if you transact from wallet to wallet? There is none! Environmental cost is another nonsense-argument; it is a lot lower than actual cash.

That's vague as can be; despite your promise of problematic, it is used. Doesn't look like it is going away either.

Aw, come on; BC is generated by using electricity, in some cases even "green". Mining gold means using a lot of environmentally unfriendly chemicals, which are often dumped nearby, polluting the area. There is no way of environmentally friendly gold. Digiconomist is spouting crap :thumbsup:

So you expect the US to disrupt a private enterprise like bitcoin because they say it is used for tax evasion and crime? So is the internet so why isn't the US shutting that down too? If they wanted to shut it down they'd legislate, no need to do something underhand that might harm their reputation and democracy.

There's no need to shut it down directly; discrediting works well enough. Harming US reputation and democracy is left to the Americans themselves, doesn't look from here like you need help with that.

Unfortunately there are, every Blockchain change requires the participant in the chain to be updated or at least enough of them. One of the reasons it takes a lot longer to process a Bitcoin than a credit card payment (if using pure Bitcoins). i.e. Every is processed, not once but multiple times (its a blockchain!), this doesn't come for free - read data centers, networks etc, all cost with environmental impacts.

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.
The only "demonstrated" application has been cryptocurrencies. It has not been shown to be cost-effective for much else; particularly "private" use. Only the "vendors" seem to have all the answers ... Where else are you going to get all those "nodes" for your computations?

Haha, and so it would be "theoretically" possible? How? It is not even the hash that is the problem, but the amount of ledgers :)

No, it's not; a blockchain and mining are two different things altogether. Mining should be expensive.

No, vague because you are trying to project a problem where there is none.

The free market claims otherwise.

I know. That was a crazy situation. I actually won an Edison in a contest and when I got it I thought it was too complicated (for what it was). What I mean is that if I wanted that level of a thing -- running Linux -- then I'd just go with the RPi. and if I didn't want something running Linux then I'd just go with a basic Arduino. It was as if they created this thing without looking around at all. It was crazy they just killed it like that though. People were just starting to use it a bit.

Great points all around. It is worth noting that it has proven to be useful for inventory tracking and it's nature lends itself to cross-company resource tracking, making the possibilities for ERP solutions interesting.
"Never attribute to malice that which can be explained by stupidity." - Hanlon's Razor
Yes, it can be applied for B2B inventory tracking, but you'd need a trustworthy intermediary to provide the infrastructure / inventory service, and you'll probably pay a hefty premium to integrate it with your ERP out-of-the-box. Alternatively, maintaining a plain-old REST point and a SignalR hub is cheaper and aligns better with a healthy software stack. And, to be cautious, you'd probably want trusted interactions when doing any B2B related activity. Companies tend to sue each other a lot when something goes wrong.

Not denying any of that. Just emphasizing that while it's largely snake oil, there are practical concerns that it can address which are largely being lost in the current buzzword mess.

I guess for me blockchain == Bitcoin, while I know that's not true. Your post simply proves that I don't know jack shit about the subject except the general idea and the Bitcoin implementation :laugh:

Can you tell a bit about the use cases?
Best, Sander Continuous Integration, Delivery, and Deployment arrgh.js - Bringing LINQ to JavaScript Object-Oriented Programming in C# Succinctly
Sorry for taking so long. Yes, I can tell you a bit about a couple of use cases: Inter-company settlement: With programmable smart contracts and a token implementation a lot of inter-company transactions and accounting can be automated. Even payments. There can be a direct link between the custom cryptocurrency and Euro in such a way that speculation is not an issue. The settlement cease to even be an issue and with a private network, legal entities can all have blockchain authority nodes eliminating the need of trust. There is the possibility to give a node to tax authorities so trust is not an issue when it comes to paying taxes. We can get reduced costs and mitigate risks of legal fines while also making it impossible for actors inside the company to manipulate numbers which can cause all kinds of harm, therefore inhibiting personal agendas. Voting: I participated of a pilot project to count the votes of an election process. The idea is to give transparency and validation to the vote counting process (not for actually voting). I also helped writing this [white paper](https://www.stemmen-telt.nl/groningen/download/Technical\_Documentation\_Counting\_Votes\_V1.0.pdf) wich goes into details of the objectives of using blockchain for the elections. The pilot happened in the Netherlands and the code is open sourced. So there is a lot of material if you would like to explore more. So, in summary, blockchain is waaaayyyy more than bitcoin. To me bitcoin is a blockchain 0.1 alpha release and currently we are in Blockchain 4.0. The thing is that it's not mainstream yet, so there is a lot of misconception and little widespread material about it. To make it harder, there are many different implementations of blockchain (like JS frameworks). The materials we find about blockchain many times only talks about it so make it too theoretical and hard to grasp. It's not until you get hands-on the code that you can actually realize how it really works.

Also it is going to hit a wall sooner or later. The more transactions, the longer the chain is. By ten years, it is going to consume a whole town's electricity just to handle one new transaction. I don't know what kind of book that the thread starter read, but I will never hop unto the ship.

Your book is probably wrong too. Your incorrect assumption is that blockchain needs to hog a lot of electricity, see my response to Sandel to get a little more context. It's actually better if you hop unto the ship now while it's still early and you can get ahead of the crowd. As a matter of fact I get so many job offers just by having blockchain on my linkedin profile. ;)
