Web3 enhances the internet as we know it today with a few other added characteristics. Web3 is:
In Web3, developers don't build and deploy applications that run on a single server or that store their data in a single database (usually hosted on and managed by a single cloud provider).
Instead, Web3 applications either run on blockchains, decentralized networks of many peer to peer nodes (servers), or a combination of the two that forms a cryptoeconomic protocol .
People can make a living by participating in the protocol in various ways, in both technical and non-technical levels.
Consumers of the service usually pay to use the protocol, similarly to how they would pay a cloud provider like AWS today. Except in Web3, the money goes directly to the network participants.
In this, like in many forms of decentralization, you'll see that unnecessary and often inefficient intermediaries are cut out.
Tokens also introduce a native payment layer that is completely borderless and frictionless. Companies like Stripe and Paypal have created billions of dollars of value in enabling electronic payments.
These systems are overly complex and still do not enable true international interoperability between participants. They also require you to hand over your sensitive information and personal data in order to use them.
The current state of building a software company. Someone comes up with an idea, but in order to start building they need money in order to support themselves.
To get the money, they take on venture capital and give away a percentage of the company. This investment immediately introduces mis-aligned incentives that will, in the long run, not align well with building out the best user experience.
Also, if the company ever does become successful, it will take a very long time for anyone involved to realize any of the value, often leading to years of work without any real return on investment.
In the blockchain anyone can participate in building it or investing in it from day one. The company announces the release of x number of tokens, and give 10% to the early builders, put 10% for sale to the public.
Stakeholders can use their tokens to vote on changes to the future of the project, and the people who helped build the project can sell some of their holdings to make money after the tokens have been released.
People who believe in the project can buy and hold ownership, and people who think the project is headed in the wrong direction can signal this by selling their stake.
In Web3, Identity also works much differently than what we are used to today. Most of the time in Web3 apps, identities will be tied to the wallet address of the user interacting with the application.
Unlike Web2 authentication methods like OAuth or email + password, wallet addresses are completely anonymous unless the user decides to tie their own identity to it publicly.
If the user chooses to use the same wallet across multiple dapps, their identity is also seamlessly transferable across apps, which lets them build up their reputation over time.
