The usual technical hurdles that apply to any blockchain, when compared with regular centralised databases: speed, cost, scalability.
In almost every case a centralised system will win out. That's why blockchains haven't really taken off outside of cryptocurrency. Blockchains are slow and inefficient.
And many blockchain projects rely on centralised servers or entities of some kind, making the whole thing a bit pointless. 🤷♂️
Lol... The politicization of everything. Guess they need to add some red in there too. Or what's the safest colour these days?
Yes, these three aspects are known as the blockchain trilemma and if you look at that $kda whitepaper you will see how it claims to go about solving it. If you do decide to dig in, let me know your thoughts.
I had a quick glance - so it's multi-layer, a bit like Bitcoin + Lightning from what I can see.
Sure, maybe, I wouldn't write it off. It's possible that something like that might be workable. It's still very likely outperformed by centralised solutions though.
AB forum is uniquely conversational. One of its charms and why I think people hang here. There have been many crypto threads over the years and I think when placed in ‘off topic’ they tended to go off the rails (left/right political mind waste) or ‘off topic’ itself then just got populated with multiple niche crypto threads. Maybe having it thinly tethered to app discussion is required for people to let off crypto steam and not have the forum descend into chaos.
On that note could crypto have saved Alchemy, furthered SKRAM development or kept the KRFT server going? I submit not but these are the things that would have been worth saving!
The consensus mechanism has no legal standing. And there's not mechanism for proving provenance when you buy/sell an NFT. Do I own the thing that I sold to you with an NFT? Who can say.
Also NFTs won't be used for things like concert tickets because they're far too expensive a solution to something that already has a perfectly reasonable solution.
Not sure what's in it for the manufacturer as this wouldn't be a particularly cheap thing to do/manage.
I mean sure, but once you start doing those things (all of which are hard, cost money and are circumvented by organized crime all the time), what is the blockchain really bringing here.
To work you'd need a trusted central party to manage and authenticate everything. At which point you don't really need blockchain. A simple digital signature would be simpler, cheaper and computationally way more efficient.
I'm pretty familiar with high volume transactional performance and the differences between distributed and centralized solutions.
Hashgraph isn't even in the same ballpark as say an SQL database from 20 years ago. Anything distributed over a Wide Area Network can't be that fast.
Again - NFTs don't have to be expensive. NFTS minted on Eth are expensive but there are lots of cheap options.

Actually this is a rare example of a practical example that might succeed. What makes it different is that they're simply digitising an existing process, in a well understood market (trade finance is one of the earliest forms of finance), where players can be legally identified easily. Blockchain here is being used to remove the necessity for a papertrail, and so if this project is successful (a number of these types of projects have failed over the past few years for a variety of reasons, not always technical - the legal issues are always complex) they will have eliminated some admin costs.
It's not a small thing, it will save money, but it's not revolutionary. Back office automation of this kind is pretty routine in financial markets.
The main problems with distributed systems are not authentication. That's one problem, but it's hardly the most significant.
Proof of work is an extreme example of not scaling (and is sort of by design), but any form of blockchain isn't going to scale once it becomes sufficiently distributed, or you have enough certificates on there. It's kind of inherent in the design. The trick as an engineer is to find something where you can keep decentralization fairly low, and the number of certificates will be tractable.
My dude... It's not even in the top 100. Can you seriously name any achievements in the history of computer science.
Oh I dunno, a computer that keeps a satellite working in space - a perfectly mundane use of technology that completely trumps anything Bitcoin has ever achieved. How about a supercomputer that can model the weather? Or, I dunno, a global network of computers with an open protocol that any computer system can easily attach to? How about some of the achievements of AI (an overhyped technology which at least has some serious achievements to its name).
Huh? People steal bitcoin all the time, and the US government has successfully seized huge number of bitcoin assets. And bitcoin doesn't allow access to the hardware of computers. I think you're referring to some of the smart contract things out there - but they don't allow hardware access. The whole point is they're using virtual machine technology - virtual machine technology that was developed by people unconnected to crypto.
I mean if we use your criteria then I guess the internet.
Yes but are they going to be cheaper than simply setting up a ticket server on AWS? The cost here is tiny. And why would someone like ticketmaster want to give up control over verifying tickets even it was cheaper (which it won't be).
i feel like parrot repeating same thig
PoW has NOTHING to do with blockchain scalability. Number of processed transactions per second has ZERO to do with hashrate size, it is related ONLY to block size and number of blocks created per time interval.
You DON'T NEED scale PoW (in terms of more hash power) to process more transactions per second.
Otherwise, in agree with 99% things you wrote in this thread, i'm trying to explain same thing here.
You are true. That is price for decentralisation and lack of need having central authority. Which ismpretty much reason why Bitcoon was made - to have monetary network independent from banks and goverments.
Good thigs, there is solution for this problem (for example LN) - so we can have both - trustless decentralized monetary nerwork which is more performant with smaller fees than traditional finance ;-)
hm i need look at this more in depth because it sounds like nonsense to me :-) Like trying to do two contradictory things (with PoW, inevitably coin price rise MUST lead to hashrate increase, which means less profitable if you don't add more mining machines, otherwise network will become unsecure)
will check their description, curious if i find some flaws in their logic ..
This is big problem, and it sounds more like marketing bla bla ..
so if they are stating thew want to stat profitable for small miners yet looking at ways to incentivize green minig there are 2 big contradictions ... i'm very suspicious here ..
Let me just ask, if MixBox from IK Multimedia were an NFT on the Lightning blockchain, would we be having these issues we are having now with their latest mishap/update?
Asking for a friend at a Tea Party.
Biggest irony with NFTs is, that most people think they are really physically stored in blockchain. Like that little jpeg of Cryptokittie, Cryptopunk, Bored Ape or any other NFT nonsense picture, is stored on blockchain or even inside your wallet.
That is not true. That picture itself is NOT stored on blockchain. On Blockchain is stored only identifier (some hash, number) and infromation that your wallet address currently owns this hash.
Image itself is stored on some central server, usually website - like Opensea.io, where in normal relational database is infomration "this image is has identifier XYZ".
So in moment somebody attacks this server and wipes out those physically stored images there, you stay with worthless token in your wallet, which holds just identifier which now points to any real existing object. LOL.
Good example why NFTs on blockchain are giga nonsense. You have decentralized information about owning some object which itself is placed completely outside of blockchain and fully controlled by some centralized authority.
It's all bad joke.
So if MixBox were an NFT we’d have the same issue since the only thing on the blockchain is my name/wallet on the ledger.
We’d have the same issue to be resolved right.
So…gotta get some Pims to add to the Tea now.
Decentralized and distributed is not the same and I wasn‘t talking about authentication. A distributed application can be operated by a single entity and usually this is the case. A decentralized application is operated by multiple parties at the time.
The is no single top list for that. Such lists are always subjective. The same as the list of the greatest movies or whatever. If Satoshi‘s Bitcoin blockchain is not on your list then it’s your judgement. On my top list it is quite high.
Not a good example. It is neither a public open application nor decentralized.
Stolen bitcoins were not a weakness of the Bitcoin software, it were always weaknesses in applications that stored Bitcoin keys, e.g. online wallets on marketplaces. The wallet keys were stolen and then used to steal the Bitcoins but the security of the Bitcoin blockchain itself had never been compromised.
Dude, if you wonder about my top list, then I start to wonder about your blockchain knowledge.
I wouldn‘t consider the internet as an application but rather networking infrastructure and protocols. Many if not most implementations of internet services had been hacked, sendmail, DNS - you name it.
Again, name a single public decentralized application that had not been compromised although many years in operation. To be fair there aren’t many public decentralized applications. I could think of Folding@home or peer2peer applications like bittorrent - the latter is not really a good example as bittorrent is decentralized but it‘s main purpose is not centered around a common data structure. Because people run nodes in such decentralized applications they have access to the internals of it. Nothing can be really hidden and you can dump, analyze and reverse engineer everything you want.
Anyway it will also be hard to name a publicly available online application that had never been compromised although in operation for many years.
I don’t really like lightning. The transactions happen off the chain and therefore it isn’t as secure as normal transactions. AFAIK, there are many possible attack vectors. I have more hope in other consensus algorithms, although noone seamed to crack it so far.
Yes but this is the basic concept which if you're either a buyer or seller of an NFT you would know by that stage, it's only the general public who remain confused or uninterested.
It works because it's an authenification issued by the artist of the fact that the buyer owns the NFT of that work so it's as legitimate as anything physical that the artist publishes as well. You could argue it's more valuable than a physical object because it could portentially last a lot longer.
If the linked artwork does disappear from the server then it would make the artist re-establish the link asap or the artwork value and his/her brand value would also drop. It's really not much different from any other part of an art practice, it's just expanding into the digital world. The art world gets it because it's only an extension of the speculation which goes on with physical artworks but it's helpful in expanding it away from all the physical galleries which historically have an advantage.
You could say it's a joke but then you may as well say the whole of the art world is a joke too which it could be, depending on how you look at it
@Gavinski, look into Filecoin (FIL) and STORJ. Both are decentralized alternatives to AWS. And they are not the only two alternatives, but they are several of the biggest.

Have you looked at Hashgraph (Hedera)?
Well - and this is also a comment on the idea that proof of work is not scalable - currently the transaction cost in Kadena's exchange (called Kaddex, and it has not been fully launched yet so only a few things are tradeable there) is (from memory) something like 0.000001 kda, which is fractions of a cent. An nft exchange called Marmalade is launching on kda and from what i gather, the fees will be free: https://marmalade.art/
So yeah, this kind of thing is a viable threat to all kinds of existing systems. Also, in terms of music nfts, you guys should take a look at $moda. https://www.coingecko.com/en/coins/moda-dao
I'm into $flux as the future of web3. It's my biggest bag, in fact.
Lots of shilling going on here...where's my wallet
Just because I put my own money into a crypto does not mean I have any expectations for it. All investments are a risk and everything could potentially disappear. I personally hold more than 30 different cryptos.
And on which exchange are you buying/selling FLUX? It is not listed on CoinMarketCap.com.
Correction: Found it. It’s still a small crypto, but that doesn’t necessarily mean anything either negative or positive. https://coinmarketcap.com/currencies/zel/
It is, however built on top of ETH.
