How justified will it be to use a blockchain without a cryptocurrency?

[Thirdspace]

That can never be possible. You already given yourself the right answer, it will be useless. What usefullness is blockchain without the cryptocurrency? I don't even think a thing like that will ever exits because without cryptocurrency there is no blockchain. The evolution of blockchain revolves around the digital currency. Even looking at the new coins that are emerging through ICOs, they need the blockchain to become what they are. Though, I do like to see what it will be like having a blockchain without a currency.

do you even read other people's comment and take them into consideration? some of them have valid point of views
the idea of blockchain is storing public data distributed amongst the users in the network
hence no centralized server which would be easily to tamper with and modify
blockchain != cryptocurrency, but blockchain technology was invented for cryptocurrency

Even looking at the new coins that are emerging through ICOs, they need the blockchain to become what they are. Though, I do like to see what it will be like having a blockchain without a currency.

Emerging ICOs = tokens? they are using the current blockchain as platform to make it cheaper to operate
and remember most ICO tokens are scams and even if they're not their lifespan depends on the platform's sustainability
if the platform failed, even a most successful ICOs would also fall with it (none happened yet as I know)

read what jseverson posted in his post, the land registry is one of the possibilities out there.
we need more people with bright ideas working on the blockchain technology and applying it to something else
the internet technology is used for a whole lot different things now compared to the first time it was invented for

Now very often statesmen and bankers talk about a blockchain without a cryptocurrency. They do not explain how much this will be useful and what expenses will be required. I think that a blockchain without a cryptocurrency will be very expensive and useless.

The blockchain is just the platform on which we can mod the things really. For example, with the help of smart contracts based on blockchain we can create big ICO projects and thus the related coins with simple mods in the codes itself.

Whether it is crypto currency or not the blockchain still remains the same at all time. As I said its just the platform on which we can play at our will. If banks would have been in the favour of decentralised chain then could have implemented it already and things could have been faster for the blockchain in terms of the development as traditional swift tech would had blended itself with it. Its just my assumption, reality could be different.

Yes, Blockchain is a very great innovation which can make the currency or digital tokens transfer and use more secure and safe for the people. It also has additional features of keeping the data of the user anonymous and away from the third person. Their and many great ICO's coming here which are based on blockchain and has also got large demand in the society and many people have already invested in it.

Sure we can use it as Freeman. I mean you can go and have the whole blockchain working for you if you can code in good way. With the help of blockchain you create your own banking system that will transact with your own set of rules. You can have your own bank which is decentralised. I'm not talking about the ICO Which work like that but physical working bank. It will work.

See it's simple, blockchain without crypto will work surely. In best possible way but its up to us how we use it.

Blockchain can be used to maintain universal accounting books where each transaction is stored in chronological order.However, there are applications in a variety of spheres - real estate transactions, copyright for music and books, tracking food supplies or raw materials entering the finished product and what not!

Different variety would really be there but doesn't really matter at all because anything can really be organized which such new innovation. Using blockchain without cryptocurrency can really stand up on his own since this is the technology which do store up data and transfer it on an organized and very fast way which there are lots of governments do already see this stuff which would really have the high chance to be adopted.

[paul00]

Blockchain doesn’t mean that a cryptocurrency must be present. Although it is initially as part of the crypto currency transactions, it serves as channel in transactions which I think can actually be adapted by other entities.

[Fazlurkhan.kz]

Coin is not a necessary condition for a proof of stake blockchain. Not all coins are dependent on blockchain, just the standards might get changed. And the real problem will be the loss of postions such as miners will be eradicated.

[Magister Magus]

Blockchain is a very simple idea (well, relatively), but with an huge potential of development.
We'll see applications in real estate, medical background, commercial transactions, any kind of public archive...
And - if it really remains decentralized - it will be the biggest revolution humanity has ever seen...

[galambo]

Blockchain technology is not only used for making a cryptocurrency and using it as a coin all over the world but it is a very great invention of this era. It can be stated as a second very powerful and use full invention after internet ass it is the future of the digital world. It will help the world to stay away from scam and it will help people to create a very safe and secure system. Blockchain technology has much application in real life and more and more people are coming up with a great idea to work with blockchain. One should know the significance of it and try to make it more useful in every process of technology development.

Exactly, you don't need tokens or coins to store data in the blockchain. There could be a blockchain just to store all names and basic birth data of all citizens and new data could be added with smart contracts (births, deaths, name changes...). There is no purpose for a currency here. Of course, such blockchain would need to be proof of stake or other concept which is not proof of work because no-one would want to mine new blocks for a blockchain that has no block rewards.

I don't think miners will ever be eradicated. I think the original Bitcoin will never switch from PoW. Ethereum will enable PoS soon, but Bitcoin will not. And there will always be some new cryptocurrencies with PoW, no matter how inefficient it is from electric power point of view. Maybe PoW will become a hipster thing but it will never die.

So.. are you serious or are you trolling? Or maybe i guess that you are just a newbie guy who do not even know what a "blockchain" is.

[Anco_Marzio]

Why do you think this? Of course, the main use of the blockchain is for cryptocurrencies, but there are a lot of domains where it can be applied with good results.
Actually, we are just at the beginning of a revolution.

So.. are you serious or are you trolling? Or maybe i guess that you are just a newbie guy who do not even know what a "blockchain" is.

created by satoshi, the first implementation of blockchain technology is bitcoin as cryptocurrency
but the blockchain technology itself can still grow and can be applied to other things
it's true blockchain based on cryptography, but... not tied solely to cryptocurrency

A block chain is a transaction database shared by all nodes participating in a system based on the Bitcoin protocol. A full copy of a currency's block chain contains every transaction ever executed in the currency.

A blockchain, originally block chain, is a continuously growing list of records, called blocks, which are linked and secured using cryptography. Each block typically contains a cryptographic hash of the previous block, a timestamp and transaction data.

Of course, such blockchain would need to be proof of stake or other concept which is not proof of work because no-one would want to mine new blocks for a blockchain that has no block rewards.

How do you secure a public blockchain without financial incentive though? Proof of Stake still implies that the system uses some form of valuable token, otherwise there'd be nothing to stake with. For Proof of Stake to work there needs to be something at stake apart from the data being stored. And even then its security is not without dispute.

Of course you could create a permissioned or private blockchain, but then you lose all the benefits of a blockchain and are just back at distributed databases.

No Blockchain - No crypto
No crypto - No blockchain.

Please explain more specifically, why do you think so?

[GreenPowerRanger]

The question is really, why should somebody share the whole data on the blockchain when there are no rewards? So the hardware is expensive and also the elctricity, it would be a huge lose. I dont think that blockchain can work without a cryptocurrencie, because the people want want to earn something or minimal to pay the cost of the hardware and the electricity.

[Brunusmagnus]

There are a lot of potential uses for the blockchain, and we are just exploring them.
There are application in properties, in real estate, in keeping trace of works and school titles, ecc.
So, we'll see.

[alyssa85]

You can have a PRIVATE ledger without a coin, but you can't have a distributed ledger.

Because the point of distributed ledgers is that the miners are around the world and unconnected to each other and they need an incentive to mine and keep the ledger - mining coins.

And the whole point of distributed ledgers is that there is no central point of failure (because it's distributed around the world) and it is trustless.

As for private ledgers, there is no point to them - you could as easily have the current system of a central database for the same cost, because private ledgers are neither trustless nor distributed, so why bother?

[Lora_ng15]

as the block can be useless I do not understand, it guarantees transparency and security, it is very useful and without a crypto currency

The blockchain is just a type of technology that allows backtracing of data with the use of a specific algorithm. Cryptocurrency is just one of the more popular application of blockchain, but the technology exists regardless of crypto.
