Tempo di lettura: 8 minuti M Metric Digital Pubblicato: 22 agosto 2026 \u00b7 Aggiornato: 22 agosto 2026 Indice dei contenuti Introduzione Linea del tempo Web2 Web3 Confronto Due mondi a confronto Transizione e sfide Perch\u00e9 il Web3 \u00e8 il futuro FAQ Intro L’evoluzione di Internet Internet ha attraversato tre grandi fasi. Il Web1 (anni ’90) era statico e read-only: solo poche aziende pubblicavano contenuti, e gli utenti potevano solo leggerli. Con il Web2, l’utente \u00e8 diventato protagonista: ha potuto creare, condividere e interagire, ma il potere \u00e8 rimasto concentrato nelle mani di poche grandi piattaforme. Oggi il Web3 promette di ribaltare questo modello, restituendo agli utenti il controllo sui propri dati, identit\u00e0 e asset digitali, attraverso tecnologie decentralizzate come la blockchain. \u201cWeb1 is browsing, Web2 is interaction but assets and profits still reside on centralized platforms, while Web3 is about ownership and freedom.\u201d \u2014 Dai Zhikang Per approfondire, visita ethereum.org \u2192 e Wikipedia Web3 \u2192 Linea del tempo Dalle origini al futuro 1 1990 \u2013 2000 read-only \ud83c\udf10 Web1 L’Internet delle origini. Un web statico, fatto di pagine HTML semplici, dove gli utenti potevano solo leggere contenuti pubblicati da poche grandi aziende o universit\u00e0. La rete era lenta e frammentata, ma gett\u00f2 le basi per tutto ci\u00f2 che sarebbe venuto dopo. Pagine HTML statiche Netscape, Yahoo!, Altavista Connessioni dial-up (56k) Contenuti corporate e accademici HTML 1.0 HTTP FTP CGI 2 2000 \u2013 2020 read-write \ud83d\udcf1 Web2 L’era della partecipazione. Gli utenti diventano protagonisti: possono creare contenuti, interagire e condividere. Nascono i social network, le piattaforme collaborative e il cloud computing. Tuttavia, il potere rimane concentrato nelle mani di poche grandi aziende (Google, Facebook, Amazon) che possiedono i dati e gli algoritmi. Social media (Facebook, Twitter, YouTube) Cloud computing (AWS, Google Cloud) Mobile-first e app native Big Data e monetizzazione dei dati AJAX REST API SPA Cloud Mobile 3 2020 \u2013 oggi read-write-own \u26d3\ufe0f Web3 La rivoluzione decentralizzata. Grazie alla blockchain, gli utenti riprendono il controllo dei propri dati, identit\u00e0 e asset. Nascono le DAO, i token, gli NFT e le applicazioni decentralizzate (dApp). Il web diventa trustless: la fiducia si sposta dalle aziende al codice e al consenso distribuito della rete. Blockchain e ledger distribuito Self-sovereign identity Token, DeFi, NFT, DAO Smart contract e dApp Ethereum IPFS Solidity Wallet zk-SNARKs Ogni fase ha portato nuovi paradigmi, ma il Web3 aggiunge un elemento cruciale: la propriet\u00e0. Web2 L’era della centralizzazione Il Web2 \u00e8 il modello che conosciamo oggi: piattaforme come social network, e-commerce e applicazioni cloud hanno reso il web interattivo e partecipativo. Tuttavia, questa comodit\u00e0 ha un costo nascosto. Data center centralizzato \u2014 il cuore dell’infrastruttura Web2 \ud83c\udfe2 Centralizzazione Poche grandi aziende controllano infrastrutture, dati e algoritmi. Gli utenti sono “ospiti” di piattaforme che possiedono i loro contenuti. \ud83d\udcca Monetizzazione dei dati I servizi sono “gratuiti” in cambio dei dati personali, che vengono raccolti, analizzati e venduti a terze parti. \ud83d\udd12 Controllo limitato Le piattaforme possono censurare, sospendere account o modificare le regole in qualsiasi momento, senza che l’utente possa opporsi. Web3 La rivoluzione decentralizzata Il Web3 \u00e8 costruito su blockchain e tecnologie decentralizzate. Non esiste un’autorit\u00e0 centrale: il potere \u00e8 distribuito tra tutti i partecipanti. Rete decentralizzata \u2014 il cuore del Web3 \ud83d\udd17 Decentralizzazione Nessun singolo soggetto controlla la rete. I dati sono distribuiti su migliaia di nodi, eliminando i punti di fallimento unici. \ud83d\udc64 Propriet\u00e0 dei dati Gli utenti possiedono i propri dati, identit\u00e0 e asset digitali. Non sono pi\u00f9 “prestati” a una piattaforma. \u26a1 Trustless & Permissionless Le transazioni e le interazioni non richiedono fiducia in terze parti. Chiunque pu\u00f2 partecipare senza bisogno di autorizzazioni. \u201cWeb3 is the vision of an internet where users own their assets, their data, and their digital identity, with the blockchain as the ownership layer.\u201d \u2014 Bitso Confronto Web2 vs Web3: le differenze chiave Una tabella comparativa per visualizzare rapidamente i cambiamenti paradigmatici tra i due modelli. Visualizzazione dei dati \u2014 le differenze tra i due paradigmi Caratteristica Web2 Web3 Architettura Centralizzata (server aziendali) Decentralizzata (blockchain, P2P) Propriet\u00e0 dei dati Piattaforma possiede i dati L’utente possiede i propri dati e asset Identit\u00e0 Email\/password, social login Self-sovereign identity (portafoglio digitale) Monetizzazione Pubblicit\u00e0 e vendita di dati Token-based (partecipazione, staking) Governance Controllata da aziende Community-driven (DAO) Trasparenza Opaca (algoritmi proprietari) Trasparente e immutabile (public ledger) Censura Possibile (account sospesi, contenuti rimossi) Resistente alla censura Affidabilit\u00e0 Fiducia in terze parti Trustless (criptografia e consenso) Fonte: adattato da ethereum.org, WebNIC e Hive Developer Portal. Approfondimento Due mondi a confronto Come si traducono queste differenze nella pratica? Ecco alcuni esempi concreti. \ud83c\udf10 Web2 Twitter pu\u00f2 censurare qualsiasi account o tweet I server delle app di gig-economy possono andare gi\u00f9 I servizi di pagamento possono bloccare transazioni I tuoi contenuti e la tua audience sono “in prestito” \u26d3\ufe0f Web3 I tweet sono incensurabili (decentralizzazione) I server non possono andare gi\u00f9 (migliaia di nodi) Pagamenti senza intermediari e senza blocchi Possiedi davvero i tuoi contenuti e la tua identit\u00e0 Transizione Il ponte tra Web2 e Web3 Il passaggio dal Web2 al Web3 \u00e8 in corso, ma \u00e8 pi\u00f9 lento del previsto a causa di sistemi legacy, vincoli normativi e inerzia culturale. Tuttavia, le aziende che iniziano a integrare soluzioni ibride stanno gi\u00e0 raccogliendo i frutti. \ud83d\udea7 Sfide della transizione \u2022 Sistemi legacy difficili da integrare \u2022 Incertezza normativa e compliance \u2022 Esperienza utente ancora complessa (wallet, chiavi) \u2022 Scalabilit\u00e0 e costi delle transazioni \u2728 Opportunit\u00e0 per le aziende \u2022 Nuovi modelli di business (token, NFT, DeFi) \u2022 Maggiore trasparenza e fiducia con i clienti \u2022 Riduzione degli intermediari e dei costi \u2022 Accesso a un ecosistema globale e permissionless \u201cBridging between Web2 and Web3 allows large companies to modernize their offerings without overhauling their core systems, unlocking the potential of Web3 concepts faster.\u201d \u2014 Maxcode Scopri come<\/p>","protected":false},"author":1,"featured_media":0,"parent":0,"menu_order":0,"comment_status":"closed","ping_status":"closed","template":"","meta":{"_monsterinsights_skip_tracking":false,"site-sidebar-layout":"no-sidebar","site-content-layout":"page-builder","ast-site-content-layout":"full-width-container","site-content-style":"unboxed","site-sidebar-style":"unboxed","ast-global-header-display":"","ast-banner-title-visibility":"","ast-main-header-display":"","ast-hfb-above-header-display":"","ast-hfb-below-header-display":"","ast-hfb-mobile-header-display":"","site-post-title":"","ast-breadcrumbs-content":"","ast-featured-img":"disabled","footer-sml-layout":"","ast-disable-related-posts":"","theme-transparent-header-meta":"","adv-header-id-meta":"","stick-header-meta":"","header-above-stick-meta":"","header-main-stick-meta":"","header-below-stick-meta":"","astra-migrate-meta-layouts":"set","ast-page-background-enabled":"default","ast-page-background-meta":{"desktop":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"tablet":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"mobile":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""}},"ast-content-background-meta":{"desktop":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"tablet":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"mobile":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""}},"footnotes":""},"class_list":["post-4381","page","type-page","status-publish","hentry"],"_links":{"self":[{"href":"https:\/\/www.metricdsa.com\/en\/wp-json\/wp\/v2\/pages\/4381","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.metricdsa.com\/en\/wp-json\/wp\/v2\/pages"}],"about":[{"href":"https:\/\/www.metricdsa.com\/en\/wp-json\/wp\/v2\/types\/page"}],"author":[{"embeddable":true,"href":"https:\/\/www.metricdsa.com\/en\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/www.metricdsa.com\/en\/wp-json\/wp\/v2\/comments?post=4381"}],"version-history":[{"count":15,"href":"https:\/\/www.metricdsa.com\/en\/wp-json\/wp\/v2\/pages\/4381\/revisions"}],"predecessor-version":[{"id":4397,"href":"https:\/\/www.metricdsa.com\/en\/wp-json\/wp\/v2\/pages\/4381\/revisions\/4397"}],"wp:attachment":[{"href":"https:\/\/www.metricdsa.com\/en\/wp-json\/wp\/v2\/media?parent=4381"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}

Tempo di lettura: 8 minuti M Metric Digital Pubblicato: 22 agosto 2026 \u00b7 Aggiornato: 22 agosto 2026 Indice dei contenuti Introduzione Linea del tempo Web2 Web3 Confronto Due mondi a confronto Transizione e sfide Perch\u00e9 il Web3 \u00e8 il futuro FAQ Intro L’evoluzione di Internet Internet ha attraversato tre grandi fasi. Il Web1 (anni ’90) era statico e read-only: solo poche aziende pubblicavano contenuti, e gli utenti potevano solo leggerli. Con il Web2, l’utente \u00e8 diventato protagonista: ha potuto creare, condividere e interagire, ma il potere \u00e8 rimasto concentrato nelle mani di poche grandi piattaforme. Oggi il Web3 promette di ribaltare questo modello, restituendo agli utenti il controllo sui propri dati, identit\u00e0 e asset digitali, attraverso tecnologie decentralizzate come la blockchain. \u201cWeb1 is browsing, Web2 is interaction but assets and profits still reside on centralized platforms, while Web3 is about ownership and freedom.\u201d \u2014 Dai Zhikang Per approfondire, visita ethereum.org \u2192 e Wikipedia Web3 \u2192 Linea del tempo Dalle origini al futuro 1 1990 \u2013 2000 read-only \ud83c\udf10 Web1 L’Internet delle origini. Un web statico, fatto di pagine HTML semplici, dove gli utenti potevano solo leggere contenuti pubblicati da poche grandi aziende o universit\u00e0. La rete era lenta e frammentata, ma gett\u00f2 le basi per tutto ci\u00f2 che sarebbe venuto dopo. Pagine HTML statiche Netscape, Yahoo!, Altavista Connessioni dial-up (56k) Contenuti corporate e accademici HTML 1.0 HTTP FTP CGI 2 2000 \u2013 2020 read-write \ud83d\udcf1 Web2 L’era della partecipazione. Gli utenti diventano protagonisti: possono creare contenuti, interagire e condividere. Nascono i social network, le piattaforme collaborative e il cloud computing. Tuttavia, il potere rimane concentrato nelle mani di poche grandi aziende (Google, Facebook, Amazon) che possiedono i dati e gli algoritmi.

Grazie alla blockchain, gli utenti riprendono il controllo dei propri dati, identit\u00e0 e asset. Nascono le DAO, i token, gli NFT e le applicazioni decentralizzate (dApp). Il web diventa trustless: la fiducia si sposta dalle aziende al codice e al consenso distribuito della rete. Blockchain e ledger distribuito Self-sovereign identity Token, DeFi, NFT, DAO Smart contract e dApp Ethereum IPFS Solidity Wallet zk-SNARKs Ogni fase ha portato nuovi paradigmi, ma il Web3 aggiunge un elemento cruciale: la propriet\u00e0. Web2 L’era della centralizzazione Il Web2 \u00e8 il modello che conosciamo oggi: piattaforme come social network, e-commerce e applicazioni cloud hanno reso il web interattivo e partecipativo. Tuttavia, questa comodit\u00e0 ha un costo nascosto. Data center centralizzato \u2014 il cuore dell’infrastruttura Web2 \ud83c\udfe2 Centralizzazione Poche grandi aziende controllano infrastrutture, dati e algoritmi. Gli utenti sono “ospiti” di piattaforme che possiedono i loro contenuti. \ud83d\udcca Monetizzazione dei dati I servizi sono “gratuiti” in cambio dei dati personali, che vengono raccolti, analizzati e venduti a terze parti. \ud83d\udd12 Controllo limitato Le piattaforme possono censurare, sospendere account o modificare le regole in qualsiasi momento, senza che l’utente possa opporsi. Web3 La rivoluzione decentralizzata Il Web3 \u00e8 costruito su blockchain e tecnologie decentralizzate. Non esiste un’autorit\u00e0 centrale: il potere \u00e8 distribuito tra tutti i partecipanti. Rete decentralizzata \u2014 il cuore del Web3 \ud83d\udd17 Decentralizzazione Nessun singolo soggetto controlla la rete. I dati sono distribuiti su migliaia di nodi, eliminando i punti di fallimento unici. \ud83d\udc64 Propriet\u00e0 dei dati Gli utenti possiedono i propri dati, identit\u00e0 e asset digitali. Non sono pi\u00f9 “prestati” a una piattaforma. \u26a1 Trustless & Permissionless Le transazioni e le interazioni non richiedono fiducia in terze parti. Chiunque pu\u00f2 partecipare senza bisogno di autorizzazioni. \u201cWeb3 is the vision of an internet where users own their assets, their data, and their digital identity, with the blockchain as the ownership layer.\u201d \u2014 Bitso Confronto Web2 vs Web3: le differenze chiave Una tabella comparativa per visualizzare rapidamente i cambiamenti paradigmatici tra i due modelli.

Ecco alcuni esempi concreti. \ud83c\udf10 Web2 Twitter pu\u00f2 censurare qualsiasi account o tweet I server delle app di gig-economy possono andare gi\u00f9 I servizi di pagamento possono bloccare transazioni I tuoi contenuti e la tua audience sono “in prestito” \u26d3\ufe0f Web3 I tweet sono incensurabili (decentralizzazione) I server non possono andare gi\u00f9 (migliaia di nodi) Pagamenti senza intermediari e senza blocchi Possiedi davvero i tuoi contenuti e la tua identit\u00e0 Transizione Il ponte tra Web2 e Web3 Il passaggio dal Web2 al Web3 \u00e8 in corso, ma \u00e8 pi\u00f9 lento del previsto a causa di sistemi legacy, vincoli normativi e inerzia culturale. Tuttavia, le aziende che iniziano a integrare soluzioni ibride stanno gi\u00e0 raccogliendo i frutti. \ud83d\udea7 Sfide della transizione \u2022 Sistemi legacy difficili da integrare \u2022 Incertezza normativa e compliance \u2022 Esperienza utente ancora complessa (wallet, chiavi) \u2022 Scalabilit\u00e0 e costi delle transazioni \u2728 Opportunit\u00e0 per le aziende \u2022 Nuovi modelli di business (token, NFT, DeFi) \u2022 Maggiore trasparenza e fiducia con i clienti \u2022 Riduzione degli intermediari e dei costi \u2022 Accesso a un ecosistema globale e permissionless \u201cBridging between Web2 and Web3 allows large companies to modernize their offerings without overhauling their core systems, unlocking the potential of Web3 concepts faster.\u201d \u2014 Maxcode Scopri come<\/p>","protected":false},"author":1,"featured_media":0,"parent":0,"menu_order":0,"comment_status":"closed","ping_status":"closed","template":"","meta":{"_monsterinsights_skip_tracking":false,"site-sidebar-layout":"no-sidebar","site-content-layout":"page-builder","ast-site-content-layout":"full-width-container","site-content-style":"unboxed","site-sidebar-style":"unboxed","ast-global-header-display":"","ast-banner-title-visibility":"","ast-main-header-display":"","ast-hfb-above-header-display":"","ast-hfb-below-header-display":"","ast-hfb-mobile-header-display":"","site-post-title":"","ast-breadcrumbs-content":"","ast-featured-img":"disabled","footer-sml-layout":"","ast-disable-related-posts":"","theme-transparent-header-meta":"","adv-header-id-meta":"","stick-header-meta":"","header-above-stick-meta":"","header-main-stick-meta":"","header-below-stick-meta":"","astra-migrate-meta-layouts":"set","ast-page-background-enabled":"default","ast-page-background-meta":{"desktop":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"tablet":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"mobile":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""}},"ast-content-background-meta":{"desktop":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"tablet":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"mobile":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""}},"footnotes":""},"class_list":["post-4381","page","type-page","status-publish","hentry"],"_links":{"self":[{"href":"https:\/\/www.metricdsa.com\/en\/wp-json\/wp\/v2\/pages\/4381","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.metricdsa.com\/en\/wp-json\/wp\/v2\/pages"}],"about":[{"href":"https:\/\/www.metricdsa.com\/en\/wp-json\/wp\/v2\/types\/page"}],"author":[{"embeddable":true,"href":"https:\/\/www.metricdsa.com\/en\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/www.metricdsa.com\/en\/wp-json\/wp\/v2\/comments?post=4381"}],"version-history":[{"count":15,"href":"https:\/\/www.metricdsa.com\/en\/wp-json\/wp\/v2\/pages\/4381\/revisions"}],"predecessor-version":[{"id":4397,"href":"https:\/\/www.metricdsa.com\/en\/wp-json\/wp\/v2\/pages\/4381\/revisions\/4397"}],"wp:attachment":[{"href":"https:\/\/www.metricdsa.com\/en\/wp-json\/wp\/v2\/media?parent=4381"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
