## What it is
Graphene is a C++ toolkit for building high-performance blockchain networks using delegated proof-of-stake consensus, originally developed for BitShares. It ships a witness node for block production and validation plus a command-line wallet that communicates over an RPC endpoint.

## Use cases
- launch a delegated proof-of-stake blockchain node
- build a decentralized exchange on Graphene
- run a witness node that signs and broadcasts blocks
- manage blockchain accounts and balances with a CLI wallet
- develop custom blockchain applications in C++
- interact with a blockchain via JSON-RPC from a wallet

## When to choose
- you need a battle-tested DPoS blockchain framework in C++
- you are building on or forking BitShares-style chains
- you want a self-contained node plus CLI wallet for block production and account management

## When to avoid
- you need a modern actively maintained blockchain SDK - development has largely moved to forks like bitshares-core
- you want a simple smart-contract platform like Ethereum-style tooling
- you prefer a language other than C++ with heavy build requirements
