"Blockchain-as-a-Service" does it worth to use?

[pereira4]

You didn't answer the question.

Do distributed systems' databases have to structured like a "blockchain", or not? Plus do they really need to be "append-only"? But, in the context of the topic, they're centralized.

thre is no law OFCOURSE to say that people need to convert to blockchains. so thats why i avoided answering your obvious question.

I'm only trying to learn why it has to be "a blockchain", if it's private and centralized, and that a database would be more effective and efficient.

Is a centralized blockchain more efficient than an append only database? Because everyone wants to ride the blockchain bandwagon.

an append only database in a central store means everyone has control and access of a single file,
imagine 100,000 people all having access to your computer. you dont know who really just hacked it and deleted the file, you dont know who just scrubbed the log files and you dont know who could do it again.
also someone can then replace it with a different copy that they pre-edited/created before popping it into your computer.
so you employ IT guys, you get auditors in, you even employ HR guys to vet people that access it. security guys that approve or revoke access to people.

an append only database distributed across multiple systems
means everyones copy just adds new entries but has no hash or chaining function to check previous entries are not edited easily
meaning it requires more labour and time and money to do stuff

but blockchains without any labour self manages and audits all the systems and keeps the database robust. think about it have you ever needed to manually request your node to verify stuff.. have you had to manually ban mischievous nodes. or has the system been self reliant with no labour overhead/costs

But isn't it as easy to cheat, or change the data in a centralized blockchain because there's no Proof of Work? What's the point of it?

Im still yet to see an application of blockchain that isn't Bitcoin, and that isn't just falling more on the gimmick side of things. Why would you need a blockchain for an enterprise, when there's already very secure mySQL databases which can be modified only if X people allow it and whatnot? And you can keep track of all modifications in a log.

The way the blockchain was structured is to make it work in a global network. Bitcoin is adversarial in nature and the whole incentive mechanism goes along with how the blockchain works and does what it does. Without the token-incentive mechanism and PoW I fail to see an application for it that is really relevant.

"Blockchain-as-a-Service" (BaaS) is a current buzz in the market as everyone wants ready to use solutions and services for their businesses. BaaS allows enterprises to use cloud-based services for building, hosting and deploying blockchain apps, agreements, and utilities. It will give the boost to the blockchain adoption for small-medium businesses quickly and cost-effectively on cloud-based platforms.
This is basic information anyone can gather on the internet, besides that what and how does it exactly work?

It sounds like a good topic. I recently attended an AMA session with Ophelius Labs and they answered some questions on this topic.

From what I gathered, the idea of BaaS is similar to SaaS because you will access it via an intranet or extranet connection. I studied many SaaS examples, but it only requires a simple log in credential and some industry-standard level of security to access. However this security is only a complex encryption and wont actively prevent DDoS attacks or something similar. With the blockchain in place, businesses and organizations can prevent MitM (man in the middle), packet sniffing, and, of course, DDoS attacks. This can lead to more secure computing for organizations and protect their sensitive data.

A few short years ago we were talking about the next big thing with information security in the cloud, but looks like we've finally reached some middle ground between confidentiality plus integrity and yet maintaining accessibility for remote or mobile workers.

I think that not necessary to use private blockchain because Bitcoin quite suitable for saving immutable data in his blockchain.
Bitcoin as a data storage is expensive but it very reliable.
Using the private blockchain may be cheaper but there will be increased risk of attack 51%.

There's no need for data storage on the blockchain. Keeping large amounts of redundant data FOREVER would be stupid. A cheap way to leverage the blockchain for data would be something OpenTimestamps is doing, https://opentimestamps.org/

Data may be stored in blockchai in case if the data is not too big and if you are afraid that data will be lost (eg. be censored). The blockchain data can not be blocked and will accessible for everyone from everywhere.

What kind of data would be too valuable for you that's worth spamming the Bitcoin blockchain in your opinion? Your marriage certificate? The Unabomber's Manifesto?

Blockchain as a Service allows the cutomers to implement blockchain related services or functionalities within their present business environments. It is defenitely worth the effort and brings in business growth and profit.
It is one among the best services that you can implement for the enhancement of your business and to gain profit.

I might be late in this discussion.

Blockchain as a service is a buzz word: a nonsense meant only to provide a flow of (fiat) money into consultant's pockets, out from the client's.

Only blockchain application that really makes sense is bitcoin.
All other cases are BS.

Coincidentally, in another post today, I suggested reading this article:
When do you need blockchain? Decision models.

Here, you can see the complete flowchart:

Why "other cases are BS" but bitcoin is not?
Be consistent please.

If you had really read the attached article should be clear by now, but basically it has to do with the trustless environment required to run bitcoin. Whilst this is not the case for any other application.

Whilst this is not the case for any other application.

Hmmm. "any other application". Really?
Please list all possible applications here.

If we include smart-contract usage, there are many possible applications such as
* DEX
* Casino
* Immutable file hosting/sharing (not really efficient and don't need smart contract, but it's good options for whistleblower)

I see that you are in opposition to the view that

Only blockchain application that really makes sense is bitcoin.

Obviously, that chart meant as a joke. There are better charts, such as :

There is a funny circular reference here, as the joke-chart is actually the first chart in the link you provided, that is the same link I linked in my post where I first posted the chart...

Correct me if I'm wrong, but isn't "blockchain's" primary value proposition is censorship-resistance, and to be censorship-resistant it had to be decentralized?

Which brings us to the next debate, does your app/company need to work through the costly inefficiencies to achieve censorship-resistance?

The chart is only one of example chart, blockchain application isn't limited for an application or company. DEX and Casino on blockchain (with smart-contract help) are the prime example which need to be censorship-resistant.

I believe many blockchain apps want to be "decentralized", and use "blockchain" because it's the "in thing" to do, not necessarily for censorship-resistance. It's marketing. Centralization is enough for MOST applications.

I agree, but it doesn't mean blockchain only suitable for decentralized cryptocurrency (which i'm trying to say in first place)

What else is blockchain suitable for? We have "blockchain projects" all around with no actual service to the mainstream, except buy and sell of their shitcoins, because they're inefficient.
