Learn about Web3 and how it differs from past versions of the internet

Distinguishing between Web 1.0, 2.0, and 3, all made possible by the internet

The World Wide Web began as read-only, static webpages on Web 1.0, where data could not be entered. With Web 2.0, the online interface became a read-write space for data entry, post creation, and forum participation, among other activities. Web3 is intended to be decentralized, user-owned, and built on blockchain technology.

Web3 is the successor to our current version of the Internet

Web1 (existing roughly from 1990 to 2005) was about decentralized and community-governed open protocols. Most of the value accrued to the edges of the network: users and builders. Web2 (roughly 2005 through 2020) was about siloed, centralized services run by corporations.

The future of the internet

Blockchain? Crypto? NFTs? Oh my. Gilles DC provides a simple breakdown of what Web3 is, what it involves, its connection with web currencies, and how you can begin your own explorations of this brave new world. Gilles promises to describe Web3 in one take, explain how the reader can take advantage of it, and how blockchain might build a better society as a result.
