# Overview

Base is a Layer 2 network that operates on top of Ethereum's architecture. It is designed to be EVM equivalent and as close to Ethereum as possible.

You can find a Base block explorer at: <https://basescan.org/>

The minor differences between building on Base and Ethereum are outlined in [Base's developer docs](https://docs.base.org/docs/differences).

Flashblocks support: Validation Cloud's Base nodes support Flashblocks for Sepolia and Mainnet. For more information about which methods you can use Flashblocks with, see the extra documentation here: <https://docs.base.org/base-chain/flashblocks/apps#eth-getblockbynumber>
