Web3 is the idea of an internet where people hold their own digital assets, identity and data in blockchain wallets, instead of in accounts that platforms control. Ethereum co-founder Gavin Wood coined the term "Web 3.0" in 2014, and ethereum.org sums up the eras as Web1 read-only, Web2 read-write and Web3 read-write-own.
How is Web3 different from Web1 and Web2?
| Era | Rough period | How people use it | Who captures the value |
|---|---|---|---|
| Web1 | About 1990 to 2004 | Reading mostly static pages published by companies | Site owners |
| Web2 | 2004 to the present | Reading and creating content on large platforms | Platforms, largely through advertising |
| Web3 | Emerging | Reading, creating and owning assets through wallets and tokens | In principle, shared between builders, users and token holders |
In Web2, your account, followers and purchases live on a company's servers, and the company can change the rules or close the account. Web3 tries to move ownership into tokens and records on public blockchains that you control with your own keys. Web3 is best understood as a set of design goals rather than a finished product: most people still reach Web3 apps through ordinary websites and app stores.
What are the core principles of Web3?
- Decentralised: ownership of the network is spread among builders and users rather than held by one company.
- Permissionless: anyone can take part without being approved, and nobody can be excluded by a gatekeeper.
- Native payments: cryptocurrency moves value directly, without banks or card processors in the middle.
- Trustless: economic incentives and open code replace trusted third parties.
All four principles rest on decentralisation, which in practice varies widely between networks and applications.
What technologies make Web3 work?
- Public blockchains keep the shared record of balances and application state.
- Smart contracts are programs stored on a blockchain that run an app's rules without a company server.
- Wallets hold your keys and double as your login; our guide to how crypto wallets work covers the options.
- Tokens represent currencies, stablecoins, voting rights or unique items (NFTs).
- DAOs let token holders vote on shared treasuries and rules; see governance and DAOs.
- Layer 2 networks and oracles make transactions cheaper and bring outside data, such as prices, on-chain.
What can you do with Web3 today?
The most used Web3 applications are financial: stablecoin transfers, decentralised exchanges and lending markets, collectively called decentralised finance (DeFi). Other uses include NFTs that record ownership of digital items, DAOs that manage shared funds by on-chain vote, and decentralised identity, where a wallet holds verifiable credentials that the user, not a platform, controls.
How can you try Web3 without taking big risks?
- Start small and separate. Use a new wallet with a small amount, kept apart from your savings.
- Protect the recovery phrase. Write it down offline and never type it into a website or share it with "support" staff. Anyone with the phrase controls the wallet.
- Check where you connect. Bookmark official app addresses and confirm token contract addresses before trading; look-alike sites are common.
- Read what you sign. A token approval can let a contract spend your tokens later. Approve only what you need and revoke approvals you no longer use.
- Know the network and fees. The same address format works on Ethereum, BNB Smart Chain and many Layer 2 networks, but tokens sent on the wrong network can be hard or impossible to recover.
- Be sceptical of high yields. Returns that look too good usually carry hidden risks, from leverage to outright fraud.
What are the criticisms and limitations of Web3?
- User experience: ethereum.org itself says the technical barrier to entry is "currently too high."
- Cost and access: transaction fees can put Web3 out of reach in less wealthy countries, which is one reason Layer 2 networks matter.
- Centralised infrastructure: many projects still depend on centralised services such as GitHub, Twitter and Discord, and on hosted front ends.
- Security: self-custody means no password reset. Phishing, malicious approvals and contract bugs cause regular losses.
- Speculation: many tokens have little use beyond trading, and prices are volatile.
Where Wealtii sits: Wealtii is not a self-custody Web3 app. You sign in with an email account, and fund assets are held for you 1:1 in a 3-of-3 multi-signature vault on BNB Smart Chain whose holdings anyone can verify on-chain via Wealtii's transparency page. Withdrawals are paid as USDT to an external BEP-20 wallet that you control.
Frequently Asked Questions
What is Web3 in simple terms?
Web3 is a vision of the internet in which users hold their digital assets, identity and data in their own blockchain wallets, and apps run on public blockchains instead of company servers. Ethereum.org describes it as read-write-own.
Who coined the term Web3?
Ethereum co-founder Gavin Wood coined the term Web 3.0 in 2014 to describe a decentralised, blockchain-based internet.
Is Web3 the same as crypto?
Not exactly. Cryptocurrencies are the payment layer of Web3, but Web3 also covers smart contract apps, NFTs, DAOs and decentralised identity. You can hold crypto without using any Web3 apps.
What are the risks of using Web3 apps?
The main risks are losing your private keys, signing malicious transactions on phishing sites, smart contract bugs and volatile token prices. There is usually no customer support that can reverse a mistake.
