# Block explorer

## Definition

A block explorer is a public interface for reading blockchain data such as blocks, addresses, transaction hashes, fees and confirmation status.

## What it means in practice

Explorers read public ledger data and can differ in indexing speed, labels and presentation without changing the underlying blockchain state.

## How this concept appears in Terenval Wallet

Terenval users can use reputable explorers as an independent way to confirm the network status of a transaction.

**Important:** An explorer should never need your seed phrase or private key merely to look up a public transaction.
