## What it is
BNB Smart Chain (BSC) is an EVM-compatible blockchain client implemented as a fork of go-ethereum, using Proof of Staked Authority (PoSA) with 21 validators for fast blocks and low fees. This repository contains the core node software (geth-based binaries) for running, validating, and interacting with the BNB Smart Chain network.

## Use cases
- run a full node for BNB Smart Chain
- operate a validator node for BSC
- deploy and execute Ethereum-compatible smart contracts
- interact with BSC via JSON-RPC endpoints
- build DeFi dApps on an EVM-compatible chain
- port existing Ethereum tooling and contracts to BNB Chain

## When to choose
- you need to run or validate on BNB Smart Chain
- you want Ethereum compatibility with lower fees and faster finality
- you are building dApps or infrastructure in the BNB Chain ecosystem

## When to avoid
- you need a general-purpose Ethereum mainnet client (use go-ethereum directly)
- you want a proof-of-work or fully permissionless validator set
- you need a Layer 2 solution (use opBNB instead)
