Question

blockchain

What kind of projects can be usefully and makes sense to transfer to a decentralized blockchain?
More specific examples are welcome.

Answer 1

It makes sense to transfer to the blockchain projects that have:
- a distributed source of information,
- a ban on changing anything that has entered the system,
- a connection (dependence) of previous documents with subsequent ones,
- public accessibility or the presence of open and closed parts.,
- unwillingness (inexpediency, impossibility) to concentrate the storage of information in one place.
Such projects include:
- storage of documents, for example - economic contracts,
- information about the ownership of real estate,
- medical histories,
- diplomas,
- cadastral information,
- information about family status, place of registration,
- "employment records" or information needed for pension funds, - vehicle
ownership (or repair history),
- storage of election progress/results information,
etc.

Answer 2

With benefit - the number of such projects is extremely small.
Blockchain is such a buzzword in general.
I agree with dmshar 's answer , but I want to add to it:
(and which, in my opinion, reduce the number of such projects to near-zero values):

The total number of transactions in the system should be measured in tens per second
(therefore, for example, it is not suitable for elections)

Answer 3

In IoT, blockchain is proposed to be used to update firmware and update device settings.
Secure messengers / chats - they already exist.
