We discuss the limitations of current services (identity lock-in, user fragmentation, data exposure) and present decentralized approaches (peer-to-peer, federated, blockchain-based) according to recent literature. We relate these models to the concept of public digital infrastructure, essential communication systems managed in a non-exclusive manner, and the notions of digital commons. As illustrative cases, we cite open protocols like Matrix and Web3 initiatives that adopt blockchain-based identity (e.g., XMTP), showing that such systems exhibit the characteristics of common resources: public specification, collective governance, and open-source software.","breadcrumb":{"@id":"https:\/\/wp.ufpel.edu.br\/gaia\/mensageria-descentralizada-como-infraestrutura-publica\/#breadcrumb"},"inLanguage":"pt-BR","potentialAction":[{"@type":"ReadAction","target":["https:\/\/wp.ufpel.edu.br\/gaia\/mensageria-descentralizada-como-infraestrutura-publica\/"]}]},{"@type":"ImageObject","inLanguage":"pt-BR","@id":"https:\/\/wp.ufpel.edu.br\/gaia\/mensageria-descentralizada-como-infraestrutura-publica\/#primaryimage","url":"https:\/\/i0.wp.com\/wp.ufpel.edu.br\/gaia\/files\/2025\/12\/Gemini_Generated_Image_r5nwsyr5nwsyr5nw.png?fit=1408%2C768&ssl=1","contentUrl":"https:\/\/i0.wp.com\/wp.ufpel.edu.br\/gaia\/files\/2025\/12\/Gemini_Generated_Image_r5nwsyr5nwsyr5nw.png?fit=1408%2C768&ssl=1","width":1408,"height":768,"caption":"Mensageria Descentralizada como Infraestrutura p\u00fablica"},{"@type":"BreadcrumbList","@id":"https:\/\/wp.ufpel.edu.br\/gaia\/mensageria-descentralizada-como-infraestrutura-publica\/#breadcrumb","itemListElement":[{"@type":"ListItem","position":1,"name":"In\u00edcio","item":"https:\/\/wp.ufpel.edu.br\/gaia\/"},{"@type":"ListItem","position":2,"name":"Mensageria Descentralizada como Infraestrutura P\u00fablica: Uma Perspectiva sobre a Web3 como Bem Comum Digital"}]},{"@type":"WebSite","@id":"https:\/\/wp.ufpel.edu.br\/gaia\/#website","url":"https:\/\/wp.ufpel.edu.br\/gaia\/","name":"Grupo de Aplica\u00e7\u00f5es em Intelig\u00eancia Artificial","description":"Promovemos a investiga\u00e7\u00e3o cient\u00edfica te\u00f3rica e pr\u00e1tica sobre t\u00e9cnicas de IA e no emprego destas t\u00e9cnicas em tecnologias inovadoras.","publisher":{"@id":"https:\/\/wp.ufpel.edu.br\/gaia\/#organization"},"potentialAction":[{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https:\/\/wp.ufpel.edu.br\/gaia\/?s={search_term_string}"},"query-input":{"@type":"PropertyValueSpecification","valueRequired":true,"valueName":"search_term_string"}}],"inLanguage":"pt-BR"},{"@type":"Organization","@id":"https:\/\/wp.ufpel.edu.br\/gaia\/#organization","name":"Grupo de Aplica\u00e7\u00f5es em Intelig\u00eancia Artificial","url":"https:\/\/wp.ufpel.edu.br\/gaia\/","logo":{"@type":"ImageObject","inLanguage":"pt-BR","@id":"https:\/\/wp.ufpel.edu.br\/gaia\/#\/schema\/logo\/image\/","url":"https:\/\/i0.wp.com\/wp.ufpel.edu.br\/gaia\/files\/2025\/11\/cropped-gaiaufpel_logo-1.jpeg?fit=200%2C148&ssl=1","contentUrl":"https:\/\/i0.wp.com\/wp.ufpel.edu.br\/gaia\/files\/2025\/11\/cropped-gaiaufpel_logo-1.jpeg?fit=200%2C148&ssl=1","width":200,"height":148,"caption":"Grupo de Aplica\u00e7\u00f5es em Intelig\u00eancia Artificial"},"image":{"@id":"https:\/\/wp.ufpel.edu.br\/gaia\/#\/schema\/logo\/image\/"},"sameAs":["https:\/\/www.instagram.com\/gaia.ufpel\/","https:\/\/www.linkedin.com\/company\/gaiaufpel"]},{"@type":"Person","@id":"https:\/\/wp.ufpel.edu.br\/gaia\/#\/schema\/person\/700c500555f9133a6c44fd223e393507","name":"gaia","image":{"@type":"ImageObject","inLanguage":"pt-BR","@id":"https:\/\/wp.ufpel.edu.br\/gaia\/#\/schema\/person\/image\/","url":"https:\/\/secure.gravatar.com\/avatar\/525fd84c409b2d96667f51e5da3c8858fdfa0eb1d38a6c8eb957f99fc519ed82?s=96&d=mm&r=g","contentUrl":"https:\/\/secure.gravatar.com\/avatar\/525fd84c409b2d96667f51e5da3c8858fdfa0eb1d38a6c8eb957f99fc519ed82?s=96&d=mm&r=g","caption":"gaia"},"url":"https:\/\/wp.ufpel.edu.br\/gaia\/author\/gaia\/"}]}},"jetpack_featured_media_url":"https:\/\/i0.wp.com\/wp.ufpel.edu.br\/gaia\/files\/2025\/12\/Gemini_Generated_Image_r5nwsyr5nwsyr5nw.png?fit=1408%2C768&ssl=1","jetpack-related-posts":[{"id":264,"url":"https:\/\/wp.ufpel.edu.br\/gaia\/recommendation-on-the-ethics-of-artificial-intelligence-unesco\/","url_meta":{"origin":422,"position":0},"title":"Recommendation on the ethics of artificial intelligence &#8211; UNESCO","author":"gaia","date":"03\/01\/2022","format":false,"excerpt":"Today, artificial intelligence plays a role in billions of people\u2019s lives.
