Web3 Link to heading
To me, Web3 means decentralized web applications based on technologies like Ethereum, IPFS (Interplanetary File System) and ENS (Ethereum Name Service). It is not about centralized crypto exchanges, which are usually built using non-Web3 technologies.
The primary role of blockchains in Web3 is to enable the incentivization of running decentralized services. In other words, they allow people to earn money by participating in hosting the services. Blockchains also enable community management by decentralized voting, virtual ownership of unique resources like domain names, and even decentralized social media, among many other applications.
In addition to writing about Web3, I have been working professionally on occasional Web3 related projects since 2016. In early times the projects were mostly related to hosting Ethereum nodes on AWS EC2 instances and integrating with the nodes using JSON-RPC. In 2022 I also worked on Aave liquidity protocol analytics, extracting the historical Aave v3 interest rates from the Polygon blockchain and analyzing them with Python and Jupyter notebooks.
