> I am not inventing anything new here, just exposing the claim vs. the reality. I have worked on on proof of concept experiments that did this. Because it's easier to showcase "data goes in here, comes out there". But that's obviously not how these products will run in production. All these experiments aim to test/showcase the viability of using a blockchain between parties. The app is just there to show the business people how it works (also for PR reasons). > The law is the last resources I cannot imagine NASDAQ and financial institutions having security issues because the financial institution doesn't recognize a message signed by NASDAQ. This is clearly ridiculous. I'm not saying that if NASDAQ signs a message that won't hold up as proof that NASDAQ said something. I am saying that if two parties engage in a transaction and it's recorded in a digital contract on a blockchain, that might not always be enforceable as such in a court.

As you said you worked on proof of concepts, not production ready products. Show me a production ready product and I can show you how you can do the same without a blockchain. As I said before and can expand now, blockchains have very specific security assumptions that are not present in a public blockchain. Once you remove those assumptions cryptographic protocols are enough to give security when organizations are not anonymous. > I am saying that if two parties engage in a transaction and it's recorded in a digital contract on a blockchain, that might not always be enforceable as such in a court.

  > Digital signatures are recognized by the law in most countries. Digital contracts are not. If you believe they are, start posting some examples like you keep asking me to do. > Show me a production ready product and I can show you how you can do the same without a blockchain. I don't know any production blockchain solutions I'm allowed to talk about. Do you know any?

    Digital contracts are recognized if you have a private contracts agreeing on recognizing them. > I don't know any production blockchain solutions Nothing more to say. There is no production ready private blockchain to show. BTW, I work in this field in very well known projects (e.g. RSK, Algorand, Xapo, Jaxx, Ripio) in the public blockchain space and have adviced companies like MuleSoft at the CXX level in the private blockchain space.

      > > I don't know any production blockchain solutions > Nothing more to say. There is no production ready private blockchain to show. Pulling things out of context eh ;) It's unfortunate you're not aware of any production ready private blockchain solutions. Maybe keep that in mind before you start with your next discussion. > BTW, I work in this field in very well known projects (e.g. RSK, Algorand, Xapo, Jaxx, Ripio) in the public blockchain space and have adviced companies like MuleSoft at the CXX level in the private blockchain space. Woah your e-penis is indeed very long! I am impressed!

        > Pulling things out of context eh ;) It's unfortunate you're not aware of any production ready private blockchain solutions. Maybe keep that in mind before you start with your next discussion. Correction: I am not aware of any production ready private blockchain that cannot be replaced by another technology not using blockchain. > Woah your e-penis is indeed very long! I am impressed! It seems you don't know how to talk here in HN. You started your thread saying "I've worked on private blockchain solutions for financial firms" then there are many of your comments where you are showing some level of experience. I am showing my level of experience in the business like you.

        > You started your thread saying "I've worked on private blockchain solutions for financial firms" Yes: I stated "I work in this field, this is what I see around me at companies that are doing private blockchains. I haven't heard these arguments around me before." While your approach is: "Here is my resume, now I demand you to give me examples so I can prove my point." > Correction: I am not aware of any production ready private blockchain that cannot be replaced by another technology not using blockchain. Ah great! Since your argument is that they can all be replaced, can you name a private blockchain solution that IS running in production that can be replaced? While you are at it: > Digital contracts are recognized if you have a private contracts agreeing on recognizing them. IANAL but AFAIK this is completely false. Do you have any examples of smart contracts running on blockchains being enforced in a court?
