What is verification and what is it for?
Verification is confirmation of the correctness of any action, object or event after verification. The term is derived from two Latin words: verus ("true") and facere ("to do"). Literally we get – "to make something true", "to confirm". Translated from English, the concept of verification means both verification, and control, and attestation, and confirmation under oath.
Verification is used in various fields – in the production of goods and services, in medicine, on the Internet. Verification of the model makes it possible to create a high-quality prototype of the future product. In IT technologies, verification is used to confirm the user's identity when working online or using payment systems. With its help, they identify fakes, defective products, correct medical diagnoses, register in online services and social networks.
Verification has value as a philosophical category, as well as in other areas of human cognition, where true statements need to be distinguished from false ones.

What is good about verification.
A blue badge (a sign that the account is verified) protects users from deception: another person or brand will not be able to impersonate you. For example, this excludes situations when fake brand accounts raffle coupons in exchange for a subscription.
Examples when there is no badge, but it is needed.
Recently, the media wrote about the fact that the Instagram account of the Cos brand turned out to be fake. It is surprising that attention was paid to this, because such situations occur regularly. If the official representative office of the brand in Russia had opened and verified a regional account, there might have been less negativity.
By the way, the account has already been deleted by the administration of the social network.
Another example: when trying to find an official brand representative office in the city (yes, there may not be one, but judging by the number of clones, it's worth it), the user will encounter a dozen unofficial profiles and possibly lose money.
