Stellar Core is the reference C++20 implementation of the peer-to-peer agent that runs the Stellar blockchain network. It maintains a replicated cryptographic ledger and processes transactions in consensus with peers using the federated Stellar Consensus Protocol.

Use cases

• run a Stellar validator node
• operate a Stellar network node
• process transactions on the Stellar blockchain
• participate in Stellar Consensus Protocol consensus
• maintain a local copy of the Stellar ledger
• set up blockchain infrastructure for payments
• develop and test against the Stellar network core

When to choose

• you need to run or operate a Stellar validator or full node
• you want the canonical, protocol-level implementation of the Stellar network
• you're building infrastructure like RPC or Horizon services that require core access
• you're contributing to Stellar protocol development

When to avoid

• you just want to build apps on Stellar - use the SDKs, Horizon API, or RPC services instead
• you need smart contract development tooling - use Soroban tooling rather than core
• you want a lightweight wallet or client library rather than a full node
• you're working with a different blockchain network
