Bitcoin, built ten times over.
✨ ✨ Ten independent full nodes. Ten languages. Zero forks of Bitcoin Core — each one synced to mainnet tip and passing all 1,222 consensus test vectors.
Meet the fleet
Ten nodes, ten languages, one protocol — each with its own personality. Hover to say hi; tap to dive in.
Mainnet sync status
All 10 implementations syncing Bitcoin mainnet. Each node validates every block from genesis independently via P2P.
Ouroboros
Hybrid Bitcoin full node in Rust + Python
A high-performance Bitcoin full node combining Rust for the hot path and Python for scripting and extensibility. Features block sync, validation, and a full script interpreter.
Every node tells a different story
The same protocol, reimagined through the idioms and strengths of each language.

What goes into a full node?
Every implementation covers the same foundational components that make Bitcoin work.
P2P Networking
Peer discovery, connection management, and message relay
Block Validation
Consensus rules, proof-of-work verification, script execution
UTXO Set
Unspent transaction output database and chain state tracking
Mempool
Unconfirmed transaction pool with fee-rate ordering
RPC Server
JSON-RPC API compatible with Bitcoin Core
Wallet
Key management, transaction signing, and HD derivation
