Web3 is built on distributed ledgers, built on decentralized protocols to enhance development. This leads to dApps, smart contracts, DAOs, AI, machine-to-machine communication, and many new paradigms that can disrupt older models. Infrastructure providers offer low-cost nodes that are easy to deploy, for enhanced scalability. They remove a very time-consuming step of the development process by providing easy node access - nodes being the primary point of infrastructure in Web3. Infura is a case in point that it could potentially lead to the same problems we saw within Web2, with restricted access to your own information.
