There used to be old times when things were too old and we didn't knew anything.
Take a typewriter, then came PC, then Laptop for more convenience and then we are seeing high quality mobiles and tablets overtaking them.
As with each new era, there came a new technology to replace old one with its upgrade.
Will there be any more advanced technology than blockchain that could replace it and be more precise than this?
I know that blockchain is something we can call as perfect ATM, but is there anything that could still beat this technology and overtake this?

You just answered it yourself, no technology will be relevant forever.
There's always a room for improvement and innovation from Blockchain Technology, blockchain itself are still new and just gained traction from mainstream corporation.
I doubt we've discovered the best use case from Blockchain itself.
Blockchain will stay for a long time before we can think of something else :)

There are already blockchain options.
Iota doesn't use blockchain technology. It uses directed acyclic graphs (dag), which is quite different.

Not a replacement, as Android is not a replacement for windows.

If you observe internet as an example of new technology, it started more than 30 years ago, in a very modest way. It had to go through different hardships and it had to learn how to scale. It had to evolve, to become faster and more widely used. Eventually, a lot of new technologies and services were built on top of it (including the blockchain!). And it never became obsolete. I believe blockchain technology today is in a similar position as the internet 20 or 30 years ago. We are yet to see scaling, wider adoption, and new kinds of services and applications being built on top of it.

Any technology will be outdated. The world of technology grows daily. Today's products are progressive but may be outdated the next day. I think it will take a long time for a new technology to replace the blockchain

I have no idea what technology can replace the blockchain. At the present time blockchain is very optimal, its defects are not so important. I believe blockchain will improve these defects. The blockchain will last a long time

I think probably the more realistic thing to "replace" the blockchain will just be an improvement in the blockchain format... sort of figuring out a way to provide a more secure/quick version of the time stamped PoW based ledger system.  There are already a ton of ways the blockchain has been changed already, but there have been pros and cons to each way you change it... if you change how the blockchain works all together, maybe in a differently layered format, then that will replace the "chain" aspect of it.

Sure technology always becomes obsolete, but usually it works on improving the older tech to become better.

Blockchain is changing the technology worldwide. This technology has had the greatest impact in the past few decades. I believe it is the next generation of internet and it will not be replaced

Everything will change and it is constant.
People will always change and that's what makes more businesses to acquire something that most people would like to. Android is just an upgrade version for Java phone and since Microsoft is too famous, Apple company did something to create their own and it suit the taste of most people in the world.
That's how people change by following the trend since it is on the trend, they tend to buy it in order to follow the trend.

I know someday someone will be going to create an alternative of blockchain or another type of blockchain.

I wonder what this would even look like or what issues it would solve?  I mean the whole purpose of the blockchain how it is is to have a way to share a distributed ledger in a peer-to-peer manner without the need for trusted third parties... do you think that these "alternatives" to the blockchain will still be in the spirit of avoiding centralized 3rd parties in distributed communications?  If so it needs to be a time stamped based server... It's interesting that I can't even fathom what that might look like without something like a blockchain, PoW-like system... but then again, we couldn't even fathom blockchain now in the early 2000's.

I believe so. The world is full of wonders and as time goes by what is modern and trending at present will become worn out and obsolete in the future. Technological discoveries occur frequently at a faster rate. Blockchain is still at its infancy stage. Surely, there's still ample room for it to make it better. And it will indeed be improved further and further but then there will always come a time that a new and much better thing will be discovered later on. For now, blockchain is going to reign for a long, long period of time. However, retirement will soon follow afterwards as the only thing that is permanent in this world is change.

A linked list and hashing borrowed from BitTorrent is not revolutionary and if block-chain is so good then
how come many developers including those developing the lightning network are running away from it.

No one walked on water here, Double agent SM is not jesus you know and we also know he made a right mess
with this stupid CPU-Wars he created in the process and the block as implemented by Bitcoin won't scale.

I don't have a clue what could replace the blockchain, I wish I would. But it is a very good futuristic question.
I'm curious what quantum computers can bring to technological development.

As of now blockchain is the highest extreme encryption and security option we have. There are few projects are proposed here and there when the hard fork happening on various coins, but exactly to say they are cannot do betterment of blockchain does here and everywhere.
blockchain open ledger is view to all and not hackable at all. Still many fastforwarded IT companies does not have blockchain integration so here those companies are now into adding it for their security firewall.

What do we want from a blockchain? Security, immutability and distribution.

I'm certain something will pop along that does a better job than what we have now. In the future people will look back at all that burnt electricity and fried capacitors and marvel.

I hope that if something is clearly superior that Bitcoin and friends can migrate their ledger to the new system without a hiccup, but I seriously doubt that'll happen and viable coins may well go down with the PoW ship needlessly.

We're still in the midst of finding out which use cases are viable for blockchains and which aren't; in other words until blockchains have superseded something in earnest it's still a bit premature to talk about whether blockchains themselves will get replaced as well.

That being said, sure. I don't think any technology stays on top forever. Blockchains and decentralized ledgers in general could very well just lead to a dead end, for whatever technological or socio-economical reasons we've yet to fully understand. On the other hand it could change the way we deal with money, property and data forever... or at least a very long time. Only one way to find out.




DAGs are merely data structure, just like blockchains. Without a secure, trustless and permissionless way to prevent double-spends we might as well fall back to centralized solutions.

I think the question is not well formed. May be op should better ask:
Is it possible for blockchain to be replaced by a superior technology that is capable to offer the same features as being distributed, decentralized,  immutable and securely resistant to so many attack vectors?

I'm busy with recent Bitmain E3 attack on Ethash atm and won't go through details but for the record my answer is definitively yes and actually I have some idea regarding this issue which will share soon  ;)

yes, IOTA is centralized, it uses Proof of Work and Proof of Authority. That´s a problem for a global currency like Bitcoin, but for some other companies who are creating their own cryptocurrency and have other goals that may not be a problem, even something desirable.

As i said, I think blockchain and bitcoin can live together with another kind of projects, like centralized DAG, or Ethereum PoS, and that´s not a problem or a treat to bitcoin. Just like android and windows.

IOTA and NANO do not use blockchain. I think in the medium term, it is impossible to come up with better and safer technology. I think the debate will only take place in relation to the nodes because maybe they change, the POW PoS debate and some other issues.
But Blockchain is here to stay. Just like the internet.

Not if they cannot make it scale (which they can) without moving off-block like is the case with Lightning network because they needed an
excuse to install banking hubs so the bankers/miners could make a bigger profit.

Block ledgers allow the block-chain to become 3D instead of just 2D and this allows for scaleability but alas
I don't think Bitcoin on the current path will be around as top dog for much longer because it's an evolutionary
dead end.

if coding, and learning computer language is easy, and if quantum core computers are available and affordable and if anybody knows how to use proper technology with the idea of being advance then maybe blockchain will be replaced as soon as possible. However this will take long long time for sure, because Blockchain is already founded in the internet and is not yet irreplaceable not unless if that replacement is good and much better than blockchain technology. i hope that the replacement is invulnerable to attacks, but more transparent and safer.

My understanding is that NANO uses blockchains, with a separate blockchain for each account (I'm not familiar with the technical details so I'm not sure how to define that.) It seems to work very well at any rate. It's like Bitcoin+Lightning Network except free (not merely cheap), and without opening/closing TX on the blockchains or the other complexity of LN.

yes can! if we devlope more secure and easy tecnology then yes . if no one control blockchen but do not harm any country rule then yes

I guess YES. The answer lies in your question itself. It is evident that evolution is unstoppable event. and there is always a scope for continuous improvement. So, there will be a replacement which will be the advance version

first I read this blockchain review which is a great computer technology and probably will not be replaced, just a genius thinker who might think about it.
