How is it trivially DOS'd? You don't need to share all your private data just the data about transfers using the system which isn't going to be particularly sensitive unless you are in a bad way financially and will be worth it to minimize the amount of settlements required of your business. I'm new to blockchains? I'm pretty sure I'm not.

Look into paxos and raft attacks. You don't know enough about this science to promote it as the cure for what ails you. As for sharing information - youre right... if you don't use blocks

"RR is trivial to DOS look at these two other schemes and the fact you didn't means you don't know what you're talking about".

I think we're done here. You're not doing anything but saying Nu uh! and calling me a liar.

It means the security is non existent. Read any of the andrew poelstra papers for details on how and why. Subjective truth has been around for decades. No one cared about it , because its not useful. The only reason blockchains are useful now is because they enable value transmission between untrusted parties. (Which private chains don't do) The only reason blockchain is a buzzword now is so that consultants can bilk…

No it doesn't mean that at all. Just because you are unable to think up a system doesn't mean it's impossible. A basic and secure enough system is trivially easy. Which paper? It is no less truthful than bitcoin. It need not be more mutable than bitcoin. It is just different. >The only reason blockchains are useful now is because they enable value transmission between untrusted parties. Right because of how current b…

Search for "on stake and consensus" I'd link to it, but I'm on mobile right now. Btw- I know you're new to blockchains because poelstra has been writing seminalpapers for years and you haven't even heard of him.

We know things are true in a blockchain because energy went into it. If only a single Bitcoin node were alive, and 99% of the network disagree with him - the energy would point to the truth. This is what makes it objective. With subjective chains there are a huge suite of problems in the form of stake grinding and long/short range attacks. Why does this matter? Non-objective quorum based sysetms have been around for decades. They're not more efficient than centralized systems for many economic reasons, some of which were really well laid out in a Isabella kaminska paper on the subject (let me know if you need a link)

Tldr: blockchains aren't paxos or raft. Blockchains mostly suck, but do one thing well: resist censorship

That entire paper is about PoS and dynamic membership systems where the participants aren't known. Relevance to the current discussion? Zero.

All those attacks are based on unknown dynamic participants which isn't an issue. So ya argue against a system they aren't trying to implement.

So you're telling this forum that the innovation here is round robin signing of network state.(not even a decent trusted consensus system like raft) I can't imagine that any halfway competant programmer in here will buy this as anything more than a trivial code construction.

Here's what will happen to your database: it'll drop the blocks and revert to a message passing infrastructure. Which is fine and good - but not in any way related to a blockchain.

So if the trust each other - passing messages in the style of SMTP (or soap) is drastically better than a hokey round robin "blockchain emulation" architecture.

At least you understand now that immutability requires energy...

Every time Ive ever heard blockchain on here it was a Bitcoin- or Xcoin-centric view involving mining. I always countered with stuff like you just said from old research into distributed, fault-tolerant DB or SCM design. I had no idea until now that there was even parallel blockchain work with no proof of work. So there might be a greater press problem at work here not bringing out knowledge of other aspects of block…

I think the main press issue is that these other chains aren't really for public use so there is little benefit to pushing for press unless you're a company that develops them trying to find clients and we do actually see a lot of stories about this in the financial news.

Makes sense.

The so-called non-work based blockchains are typically just presented as blockchains for the marketing hype. These are run of the mill paxos databases which isn't very useful compared to modern signed message sending platforms that companies like swift use

I figured it was something like that. Makes sense. Audible sigh once more for effect of marketing hype on comprehension.

I think I was turned off because I envisioned a much grander future for blockchain tech than a glorified clearinghouse for big banks. Banks will never use a public network (like Bitcoin) to manage inter-bank transfers. They'll take the underlying technology and create a custom, private network where they can tweak protocols to their liking. The hard part will be for the banks to form a board to oversee the network, b…

I doubt their private blockchain will work for the very same reason they want a private blockchain - they're not trustworthy. The bitcoin blockchain is secured by the large number of disparate people mututally checking the system. When it's just banks involved the number of players is reduced by many orders of magnitude and it becomes very much easier to game the system. The incentive to steal large amounts of money…

How would you steal large amounts of money on a private chain?

No reasons? The nature of the Bitcoin's SHA-256 POW means that individuals can no longer meaningfully contribute to the integrity of the chain, and this responsibility is increasingly held by fewer individuals with access to (relatively) expensive specialized ASIC machines. The Bitcoin system has (relatively) few legit trade opportunities yet, but is well used by scammers and black marketeers. The median person has l…

There is not reason to use this web thing (thats fully of dirty porn and nerds) for shopping when we have paper catalogues There is no need to send email when you can send a fax There is no need to carry a brick with you to make calls There is no need for plastic cards when one can use cash And so on, just because YOU do not grasp advantages and possibilities that bitcoin has brought along, does mean the rest of us d…

In all those cases they were a clear improvement. Bitcoin is almost always a worse experience though.

What ways has Bitcoin improved your life dramatically?
