    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.

    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.

      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.

        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.

                        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.

                          Dunno. If someone told Trump that he can shut down something Al Gore invented, he'd probably do so :)

                          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.

                            Yes but you don't buy a more costly door with a lock if its not required - see below!

                            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.

                            Yep - vague as I don't know what the solution is! Not saying there isn't a role for blockchain technology somewhere, but as it stands its not that good a performer in terms of efficeincy. Bitcoin took another dive this week based on an article with similar points to above Bubble trouble? Bitcoin hits one-week low - London Business News | London News | Londonlovesbusiness.com[^]

                                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.

                                  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:

                                  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.

                                        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.

                                        I wanted the prototype. The prototype Edison was packaged on an SD-card format with WiFi capabilities. Power draw was promised to be compatible with standard SD-card max draw. I know at least 1 of those got build.

                                          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.

                                          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.
