Level 4: What is this world?

What is a block explorer?

A block explorer is like a search engine for a blockchain. It gives you a window into everything happening on the network, letting you look up individual transactions, wallet activity, token details, and more. Whether you're checking the status of a payment, verifying a smart contract execution, or just exploring, a block explorer is the go-to tool.

But it's more than just a viewer. Block explorers also give insight into the health and performance of a blockchain. You can see how busy the network is, how many nodes are running it, what current gas fees look like, and whether transactions are moving smoothly. For developers, users, and researchers, it’s an essential resource. For policymakers and the general public, it offers something rare: real-time, public transparency.

Why do we talk about block explorers at Owl Explains? Because they show how blockchain isn't just secure, it’s visible. Anyone, anywhere, can track activity without needing special access. That level of openness is what sets blockchain apart, and it’s part of what makes this technology worth understanding.

If you’re curious, the Avalanche Explorer is a great place to see this in action. You can watch blocks being added to the chain in real time and follow transactions as they move across the network. Explore more here: https://subnets.avax.network
