Web 3.0

Web 3.0 describes the vision of a decentralised web in which users control their identity, data, and digital assets themselves. Instead of relying on central platforms, Web 3.0 applications use blockchain networks, smart contracts, and tokens. Advocates frame it as the logical successor to Web 2.0, critics see a marketing label.

Technical foundations

At the centre are public blockchains such as Ethereum or Solana, which run smart contracts and manage tokens. Wallets replace classic logins, decentralised storage systems such as IPFS provide an alternative to central servers. Applications are called dApps and work without the classic database backend stack.

Real world use cases

Well known examples are decentralised finance applications, NFT marketplaces, and gaming ecosystems. In marketing, brands experiment with token rewards, NFT drops, and loyalty programmes on the blockchain. Pitfall: the user base is small, the user experience is demanding, and regulatory uncertainty remains a central issue.

Context in marketing work

For most companies Web 3.0 is currently an experimentation field, not core business. If you want to reach an audience in crypto communities, you benefit from Web 3.0 mechanics, while classic consumers tend to be sceptical. Strategically it is worth observing the development and testing single campaigns rather than shifting entire business models upfront.
