Many people confuse Web3 and blockchain, thinking they are the same thing. But in fact, although these two concepts are related, they are completely different.

Blockchain is a foundational technology, an implementation of a distributed ledger. Web3 is a broader ecosystem vision that depicts the next generation of the internet—where users own their data, control their identities, and manage their assets.

In other words, blockchain may be a tool for building Web3, but Web3's realization does not necessarily depend on blockchain. Blockchain has many application scenarios that are completely unrelated to Web3, such as supply chain traceability, medical records, and more.

So next time someone asks you, "Is blockchain Web3?", you should be clear—in these two concepts, the dimensions are fundamentally different. Clarifying this point is the only way to truly understand what is being discussed in this field.
