The USDC explainer calls Web3 the next phase of the internet, marked by decentralization and user empowerment. Six outlets answer the question here: USDC, freeCodeCamp, OVHcloud, Metana, Nym and PCMag. Four of the six are company pages (USDC, OVHcloud, Metana, Nym), so their statements are their own definitions and risks. Nader Dabit, whose freeCodeCamp article is one of the six, is affiliated with Edge & Node, where he says he works on The Graph.
Key facts
- Origin: The concept was coined in 2014 by Gavin Wood, co-founder of Ethereum (OVHcloud, page undated).
- Wallets: Web3 apps typically need a self-custody wallet, such as MetaMask or Phantom (USDC).
- Lost keys: Losing the private key means losing everything, and transactions cannot be reversed (Metana).
- Networks: Web3 apps run on blockchains, on networks of peer-to-peer nodes, or on both (freeCodeCamp).
- Records: Blockchain records are public and permanent (Nym).
- Status: PCMag, in a Feb. 15, 2022 article, said Web3 was still largely theoretical, with a steep learning curve.
What Web3 runs on
Nader Dabit's freeCodeCamp article says Web3 apps run on blockchains, on networks of peer-to-peer nodes, or on a mix of both. Its author argues the case, so the piece is opinion as much as description.
Web3 is the next phase of the internet, characterized by decentralization and user empowerment.
How the parts work
USDC names blockchain as the fundamental technology that enables decentralization. OVHcloud describes a blockchain as a digital ledger that keeps data secure without a central authority or third party. It also says smart contracts automate actions once preset conditions are met.
Who holds user data today
OVHcloud says the big tech companies running the sites users visit own and manage user data. PCMag, in an article dated Feb. 15, 2022, said that, as many people saw it, users were required to surrender personal data to use services from tech giants.
What the pitch changes
Metana says Web3 gives users control of their data and digital assets through blockchain, rather than corporations. USDC says Web3 systems are generally permissionless. That means most people with an internet connection can reach decentralized apps (dApps) without approval from a central authority.
Wallets, lost keys and payments
USDC says Web3 apps typically need a self-custody wallet, such as MetaMask or Phantom. Metana says the main risk is losing the private key, which means losing everything. It also says blockchain transactions cannot be reversed.
Speed and public records
Metana says most blockchain networks handle only thousands of transactions a second, well below traditional systems. Nym, which promotes a privacy product, says blockchain records are public and permanent.
Three questions test the pitch: who holds user data, what follows a lost key or a payment, and how fast networks run.
Today's web and Web3 on three questions
Which model answers each question, and where do the selected claims say nothing?
| Question | Today's web per the sources | Web3 per the sources | Source |
|---|---|---|---|
| Who holds user data | Big tech companies running the websites users visit (OVHcloud) | Users, through blockchain rather than corporations (Metana) | Source: What is Web3? (ovhcloud.com), accessed Oct 18, 2026 · What is Web3 in 2026? Real Use Cases, Careers & What Actually Matters (metana.io), accessed Oct 19, 2026 |

| Transactions per second | Far faster, per Metana (no per-second figure given) | Most networks handle thousands of transactions a second (Metana) | Source: What is Web3 in 2026? Real Use Cases, Careers & What Actually Matters (metana.io), accessed Oct 19, 2026 |
Cells read Not covered by the selected claims where no selected claim answers the question, and every Web3 cell comes from Metana.
Limits the sources name
OVHcloud says the space remains mostly unregulated. It also says a dApp may still be majority-controlled by one company or entity, even though decentralization is a core pillar of Web3. PCMag, in an article dated Feb. 15, 2022, said Web3 was still largely theoretical, with a steep learning curve.
What is confirmed and what is not
USDC, freeCodeCamp, OVHcloud and Metana each describe blockchain as part of Web3. Big tech control of personal data appears in both OVHcloud's account and PCMag's.
Metana makes the lost-key and irreversibility points, Nym the public-records point, OVHcloud the regulation and dApp-control points, and PCMag the learning-curve point. This article uses none of the fee, token-price or adoption figures in the sources.
Analysis: who carries the risk
The statements move responsibility toward the user. The wallet holds the access. Metana says losing the key means losing everything, and that transactions cannot be reversed. It also says no 'forgot password' option exists, so the key is the one thing a user cannot afford to lose. OVHcloud's caveat raises a second question: calling an app decentralized does not settle who controls it.
No primary document is among the six sources, so each point here is what an outlet says. Before you send a payment, remember that Metana says blockchain transactions cannot be reversed. A separate explainer covers how cryptocurrency transactions work. Another covers what a crypto paper wallet is and whether it is still safe to use.
