Web3 - my attempt to explain

Recently, I saw in our community questions like "what is Web 3?", "How can this improve my product?", "Who even needs it?". Here is my short attempt to explain this new trend and answer questions above.

1. Web 3 is about ownership

TL;DR

If you have a game with microtransactions - the user really buys a legendary sword that he can sell, give away, or upload to a physical wallet and bury it in the ground. It really belongs to an user, and you, as the owner, administrator of the game, cannot change it, you are no longer a god. Users don't have to trust in Gaben, that they won't lose their skins due to unfair overwatch verdict.

Web2: when you sell something in your project, the client has to trust you that you will keep your word and the funds deposited will really stay in his account. For example, when depositing funds to an SMS or e-mail sending service, the customer must believe that these funds will be in his account and that he will be able to use them to send these messages. By keeping a log of how many funds user has in a centralized database, we can allow a simple transfer of these funds, but we as the admins have the possibility of manually overwriting this database - including users' funds. We are gods ;)

Web3: The situation is different when funds are allocated on the basis of tokens living in a decentralized blockchain. The customer has them 100% - they can keep them in their wallet and spend them in our application, but they can also exchange or sell them in any way - they can simply decide how to use something they paid for. If he changes his mind or does not use all the funds, he does not have to wonder if we will refund him money for the funds purchased two years ago.

2. Web 3 is about transparency

One of the many features of smart contracts is that once they appear in the blockchain, they cannot be changed and everyone can see what its functions are. Anyone with minimal knowledge of Solidity's syntax can check how it works and be 100% sure that its functionalities will not change. If an app says it allocates 20% of its revenue to a tree-planting foundation and writes it in the contract - we don't have to take their word for it, we can just be sure of it.

Yes, it is true that a company can be open-source oriented. But we as users have to believe that what is on the server = what is in the repository and that it will not change over time.

3. Web 3 is about privacy, security and non-discriminatory environment

In most applications, you don't need to enter any personal information. Just connect to your wallet. No more sharing your e-mail address to 10,000 entities. End of data leaks as we know them now. No more having to come up with difficult passwords.

As we do not share any data, the user can be sure that he will not be discriminated against by his location, sex, skin color or age. Even when applying for a loan or insurance.
