Yes of course, but in this case the coins give value to the blockchain itself. If we remove the economic part, do you really think someone will use that system?

Not very likely with a PoW implementation as the economics of the "coin" is what enables the "work" to get done (unless of course the mining is all government provided).

But with other low-cost consensus systems (and so far none have really being proven to be anywhere near as reliable as Bitcoin) the motivation could be the value of what else the system can provide (e.g. a decentralised "blogging" implementation) so assuming the cost to participate is negligible then the utility of the software platform could provide the reason for people to support the network (much like the motivation for running a ToR node).

Yes, it exists.
There are several companies with blockchain-like systems so that their employees can access and update some important data all over the world.

A blockchain (Bitcoin -but without coin) model should be decentralized and opened to ALL. If it is limited to only few people than it is not a real blockchain.

Of course,I mean it is possible a blockchain without the purpose of an economic system,called coins.
Just have your own miners and using blockchain for other things

It's possible...

Let's say a group of companies, for whatever purpose, require a blockchain to survive. Said group of companies then pool together resources to mine their own blockchain.

The reward, for the miners (aka themselves) would be the continued existence of their company, since we assumed that the company requires blockchain technology to survive, for whatever purpose.

It would be interesting to know what purpose that would be.

Information could be a purpose.
Let's take NSA for example.
They want to spy on everything and have information on everything.

No, it is not possible. No blockchain, no Bitcoin.

Maybe IBMs next OS will have required online and a mining program built in. There's their block chain. Otherwise if they control it in-house its not decentralized and pointless.

Some of you are missing the point. I am not talking about a crypto currency blockchain, but a blockchain with other storage uses.

The blockchain is a effectively a decentralised database. It is kept secure by the number of miners. There incentive to mine is a reward, fiat or crypto. You can store any data you want on the blockchain, the downside is the size of the blockchain.

If you are asking if it is possible to have a blockchain wihtout ANY financial reward, the only reward is the fidelity of the data. Yes, it is possible, but there will not be many miners and the security is weak.

A "functional" blockchain where the main purpose is something other than money transfer can exist but some form of "token" system is usually required to a.) provide an incentive for miners to maintain the network and b.) to prevent people from abusing the network's functionality since things like storage and bandwidth are a limited resource. The first reason has already been mentioned by others in this thread but the second reason is also quite important.

Take Namecoin for example. It works pretty well as a decentralized DNS system but there must be a cost associated with registering domains in order to prevent people from spamming the network and claiming all the domains. A token or currency with a limited rate of generation is the most suitable solution since things like nodes, IP addresses, etc. are not limited and if used, they can make the network vulnerable to Sybil attacks. Datacoin uses the blockchain as a store of data but since storage is a limited resource, it must be bought with coins which are limited in number.

Blockchain is a communication protocol + database technology and it can survive as long as there are two nodes exist on the network, broadcasting and confirming transactions. You can have small micro controllers built-in to every smart device in the world using blockchain tech (generic term) where everything is interconnected and talking... Possibilities here are unlimited.

So far Bitcoin blockchain is by far the most stable and powerful maintained by thousands of independent nodes across the world, but this does not mean it can not survive just two miners running full Bitcoin clients on their old laptops if necessary. Brilliance of the blockchain is it's scalability among other things. The Elders here can correct me if I'm missing something.

Looking for campaign manager? Contact icopress!

Blockchain is just a (smart, decentralized, ... ) database after all.
You can make it support the data you need, maybe you make it more like PoS than PoW and .. you make all the branches of your organization "keep the wallet open".
All the data is safe, which is the actual reward for the organization to maintain and keep the blockchain alive.

Is it a good model? Some organizations / corporations may already use this.

Blockchain can have a lot of uses not only just for cryptocurrencies but other things too...so I see no point in having a cryptocurrency without a blockchain because there wouldn't be anyway to support it either...blockchains are kind of important in a way to support the network...

It depends on the purpose of the chain. It could be used to decentralise and secure voting polls for democracy, if you see what kind of money and thus incentive is pushed into bringing democracy to other countries, that could be used. You can donate your computer time to mine for proteins or genes without any incentive, people are doing it. Supporting democracy and a fair voting system with a ledger and openness could be incentive enough to get people to mine. Mining started small, you do not need big rigs and money as an incentive for a blockchain to be usefull. To think it does is narrow minded.

Securing blockchain ( Public ledger ) is for the benefit of the behind cerntralized party. The mentioned blockchain without bitcoin is like some kind of database including the required information such as personal detail, product detail, sale record etc. The behind cerntralized party keeps the database running.

Why do the masses need a blockchain, if it does not have a decentralized currency (or a decentralized utility)?
Why doesn't the companies/governments just use their current systems?

The blockchain (or the public ledger) exists because you need to prove ownership in a decentralized and trustless way.
Companies and Goverments are centralized and considered trusted. Why blockchain their business?

Please provide a real world example, including the benefit to the masses and the actual mechanics.
I seriously do not know a real world scenario.

You have made some reasonable points.

It has also occurred to me that there is no need for a government funded blockchain if the bitcoin one already exists.

I concede.

DAO ↔ DApp

Companies have secretly been using blockchain technology behind the scenes for many years. Blockchain technology is a peer-2-peer service that stores unchangeable data. Within a closed system it can used quite efficiently to maintain records that no one person has control over.

An excellent tool to prevent corruption within large organizations.

Not really possible, the only reason the Bitcoin blockchain is maintained is because there is an incentive for miners to keep it running. As for a blockchain that doesn't relate to cryptocurrency, again, there has to be some sort of incentive to keep it running.
