'Web3 is not About Blockchain or Decentralization' by TheBojda web3 blockchain
Blockchain and decentralized architectures are tools for this democratization, and yes, Proof of Work blockchains, like Bitcoin have huge energy consumption, and depending on the energy source, they also have a huge carbon footprint which is bad. It always makes me frustrated when I think about that huge computing capacity that these PoW networks burn. Human kind has many problems that could be solved by huge computing capacity.
But PoW is only one way of reaching consensus. There are PoS, PoA, PoH, and other non-mining PoX consensus mechanisms that don’t need supercomputers and power plants. These nodes can run on a simple PC or on an IoT device with minimum energy consumption. New blockchains like Solana or Polygon do have not much more consumption than a centralized system.
Another typical argument is that these decentralized systems are not really decentralized. For example, most Ethereum users use it through Metamask or other centralized systems. Yes, it’s true. But why is it a problem? The point is not the direct p2p connection. The point is that you have the opportunity to change your provider any time or run your own node in the cloud, or in your home, or wherever you want.
A decentralized Uber, or Airbnb, or decentralized Facebook doesn’t require a direct p2p network where everybody runs their own node. A DAO that runs a very similar architecture that the existing companies run is a good example. The service itself doesn’t require blockchain or magical decentralized protocols. It is the same old “web2 style” cloud architecture, but it is driven by a DAO. And this is the point. Users can make their own decisions about the platform development, monetization, etc.
