Why can you use blockchain in your project, and moreover, in a startup?

Question

IT education

I have such a feature (I don’t know, is it just me?) - while working on a project, I got used to clearly present the practical application of such projects, not only for humanity, but also for their creator. I study technology - and I know what can be done on this technology and why.
Without this, I have little interest (that is, without this, I am not inclined to study something on my own, and not what is needed for current tasks from the authorities). And this in some projects leads to very, very poor performance.
Therefore, I need information that blockchains provide.
And I immediately say:
1) a decentralized currency doesn’t really attract me, what’s the point, I once had my own ideas how to launder CONVENTIONAL electronic money in secret from the special services, if that’s the point.
2) high load seems to have been realized even without blockchains. what is their profit.

Answer 1

The very term Blockchain partially characterizes its tasks and purpose. The "Block" part is the blocks, "chain" is the "chain". It turns out that Blockchain is a chain of blocks. And not just a chain. It follows a strict sequence.
What are these blocks and what is the chain? Blocks are data about transactions, transactions and contracts within the system, presented in cryptographic form. Initially, the blockchain was (and still is) the basis of the Bitcoin cryptocurrency. All blocks are arranged in a chain, that is, they are interconnected. To write a new block, sequential reading of information about old blocks is necessary.
All data in the blockchain is accumulated and forms a constantly updated database. It is impossible to delete anything from this database or replace/replace the block. And it is "limitless" - an infinite number of transactions can be recorded there. This is one of the main features of the blockchain.
Decentralization – there is no central/master server on the chain. Each participant is a server. It keeps the entire blockchain running;
Transparency - information about transactions, contracts, and so on is kept in the public domain. However, this data cannot be changed;
Theoretical infinity - theoretically, the blockchain can be supplemented with records indefinitely. Therefore, it is often compared to a supercomputer;
Reliability - To write new data, a consensus of blockchain nodes is required. This allows you to filter transactions and record only legitimate transactions. It is impossible to change the hash. This feature of the blockchain is described in the picture below.
Cryptocurrencies are one of the possible use cases for blockchain.
Most blockchain implementations are quite slow. So high loads are not about blockchain at all.

Answer 2

For hype. By the way, this is the most common reason for its use.

Answer 3

1. while working on a project, I am accustomed to clearly understand the practical application of such projects,

2. not only for humanity, but also for their creator

3. Therefore, I need information that blockchains provide

Dude! You what? Covered?!
PS: If there is an understanding, then for the creator of the service it's just a "prestige": it's just a trick for the creators and nothing more...
Well, of course, a BONUS !

Answer 4

Look at examples of using smart contracts - for sure there will be thoughts where this can be applied.

Answer 5

Therefore, I need information that blockchains provide.

sorry, bro, not all information is available for your / my current position
touch (but hardly understand) you can use this news the
only benefit is not to go into startups
