Web3 stands for the vision of a decentralized internet based on blockchain technology, smart contracts and cryptographic security
is based. The goal of Web3 is to take back the power in the network from the tech giants
and central platforms and to the users themselves
transfer - so an internet that really belongs to you. In contrast to
Web 1.0 (static reading of web pages) and Web 2.0 (social networks, monopolization of data by a few companies), Web3 relies on decentralization, digital self-responsibility and direct interaction without middlemen.
Specifically, that means:
You own your data, not Google, Facebook or Amazon.
Digital values (e.g. cryptocurrencies, NFTs) are directly in your wallet, not on foreign servers.
Decentralized Applications (dApps)
run on public, distributed blockchains and enable
Peer-to-peer systems - from financial services (DeFi) to gaming.
Smart contracts automate contracts and transactions - securely, transparently, without banks or notaries.
DAOs (Decentralized Autonomous Organizations) give users collective decision-making power over projects and communities.
Technical basics
Web3 is based on blockchains such as Ethereum, uses cryptocurrencies as
Means of payment and incentive system, and relies on decentralized
Identity solutions so that users can fully control their accounts
can. The most important features are decentralization (no central control instance), transparency (public blockchain data), censorship resistance (availability even in the event of censorship attempts) and digital sovereignty (no platform switches you off).
Opportunities & Challenges
Web3 enables new business models (creator economy, NFTs,
Metaverse), makes transactions faster and more secure, and gives users
real ownership rights to digital assets. However, there are still
obstacles: Difficult user-friendliness, regulatory uncertainty and security risks with smart contracts and wallets. Not all projects have arrived in everyday life yet, but the progress is rapid.
Conclusion
Web3 is not a state, but an ongoing upheaval: more
Self-determination, less dependence, an open infrastructure. Who
invests in crypto today, uses DeFi or collects NFTs, is already
Part of this development - and can actively shape the future.
