His interpretation of the term prevailed\u2014most people using the term \u201cweb 3.0\u201d until recently meant precisely the semantic web, that is, a network in which the content of web pages would be meaningful to computers and machine-readable. Somewhere around 2010-2012, there was much talk about ontologization, and semantic projects proliferated, but the outcome is well-known to all of us\u2014we are still using the internet of version 2.0. Essentially, only the schema of semantic markup Schema.org and the knowledge graphs of internet giants like Google, Microsoft, Facebook, and LinkedIn have survived.<\/p>\n<p>The new powerful waves of digital innovation helped to hide the failure of the semantic web. The interest of the press and the public shifted to big data, the Internet of Things, deep learning, drones, augmented reality, and of course, blockchain. While the first items on the list are predominantly offline technologies, blockchain is a network project in its essence. At the peak of its popularity in 2017-2018, it even claimed to be a new internet (this idea was repeatedly voiced by one of the founders of Ethereum, Joseph Lubin).<\/p>\n<p>But as time passed, the word \u201cblockchain\u201d became associated not with a breakthrough into the future but rather with unfulfilled hopes. Naturally, the idea of rebranding emerged: let\u2019s not talk about blockchain as a self-sufficient project but rather include it in a stack of technologies that embody everything new and bright. Immediately, a name was found for this \u201cnew\u201d concept (though not a new one) - \u201cweb 3.0\u201d. In order to justify this lack of novelty in the name, it became necessary to include the semantic web in the stack of the \u201cbright\u201d. <\/p>\n<p>Teh\u00e1t jelenleg nem a blokkl\u00e1nc, hanem a decentraliz\u00e1lt internet web 3.0 infrastrukt\u00far\u00e1ja van f\u00f3kuszban, amely t\u00f6bb alapvet\u0151 technol\u00f3gi\u00e1b\u00f3l \u00e1ll: blokkl\u00e1ncb\u00f3l, g\u00e9pi tanul\u00e1sb\u00f3l, szemantikus webb\u0151l \u00e9s az IoT-b\u0151l (internet of things).
