The blockchain can be used only in the cryptocurrency.

True

No, come on! Of course, the combination of “blockchain + cryptocurrency” is close to the perfect one, but this is not the only possible relationship. Both sides can perform well without each other. Blockchain has everything needed for use in any industry and any business where distributed ledger technology is required.

Not True

Right, opportunities and prospects of the blockchain are much more than cryptocurrencies. Although, undoubtedly, we owe one to the cryptocurrencies when it comes to the general public knowledge about the blockchain. There are already many projects where the blockchain is used or is supposed to be used, and they are not related to cryptocurrency at all. The blockchain is the guardian of finance, public sector, health and even social technologies.

The blockchain is not just a storage engine.

Not True

You’re right! Undoubtedly, blockchain is a rather advanced storage mechanism, but its main advantage is not about that. The blockchain represents much more. At least, it is a system that allows bringing together the two sides of processes, providing a trusting relationship.

True

Alas, you greatly underestimate the blockchain. If the whole thing was about the simple storage mechanism, then the blockchain would not have any particular advantages over, for example, cloud storage. However, this is not the reason we love blockchain for.

The blockchain is too hard and not suitable for everyone - only for the people from the technology field.

True

You are mistaken. Of course, if you want to make something with on the blockchain base, you can’t proceed without specialized technical knowledge. However, to use the services and products on the blockchain the special expertise is not necessary. You just have to wait until the technology becomes more widespread and all the services that use it will have more friendly interfaces.

Not True

You think correctly! More and more people are gradually acquiring some knowledge of the crypto world and the possibilities of the blockchain, technological erudition is increasing. Also, in general, to be an ordinary user of the service on the blockchain, it is not necessary to have specialized knowledge. Does anybody think about how electricity works when he presses a switch in the room?

The data will not be stored in the blockchain forever.

True

You do know a lot about the blockchain! Indeed, the blockchain data requires a lot of memory for storage. Also, if you still have enough storage space, it does not mean that in the future the situation will remain the same. Unfortunately, the amount of data is growing very fast.

Not True

Are you surprised? It is alright because surely you have heard about the property of the blockchain from the category of “the pen is mightier than the sword.” However, information in the blockchain weighs a lot, and very soon even the most modern hard drives will not be able to store it all. The eternity of data in the blockchain, unfortunately, is limited by the progress in the field of device memory. And not the fact that they will always go side by side.

There are many blockchains.

True

It’s like that. So although we are accustomed to using this word in the singular, there are many blockchains, and they are separated from each other, working independently.

Not True

Alas. Perhaps you were baffled by the hype surrounding the blockchain of the Bitcoin – this is the most famous blockchain. However, in reality, there are a lot of them, and they do not connect – it is impossible to make transactions between the blockchains at the whole. For now.

Anonymity in the blockchain is a good thing.

True

Admit it, you are a crypto-anarchist in your heart and fell in love with the blockchain for transparency, coupled with anonymity? Anonymity (in fact, pseudo-anonymity) in the blockchain is, like openness, but, alas, this is not very good – with the same success you can reveal all the details of your credit card. Why not?

Not True

Indeed, this is not good at all. Simply because anonymity is not absolute. Yes, an individual will not know who owns this particular purse … However, if you made a transaction, say, to a friend, now he knows that this wallet is yours. Moreover, he can take a look at your data – when, how much and where. Do you really have nothing to hide even from the closest ones?

Many world states against the blockchain.

True

Well no! Despite how much the world countries would like to track the wallets of their citizens, they are not really against the blockchain. Many states limit cryptocurrencies, but we already did understand that these are different things?

Not True

Indeed, why argue against what can be of use? It is difficult to deny the prospects of technology, not in vain, the Hyperledger consortium, which deals with the study and promotion of the detachment, includes several hundred companies from dozens of countries.

Data recorded in the blockchain can’t be altered.

True

You do understand things! Indeed, you can not change the data in the blockchain, they are encrypted and added to blocks that can’t be altered, but we know that this is not the only way? Forks with their rollbacks have not yet been canceled!

Not True

You are mistaken! We hope this did not influence your faith in the blockchain! However, the once-recorded data, indeed, can not be altered. However, you can change it – for example, by making a rollback, which will undo the last changes (as with the PC).
