+tagline: Run a Namecoin full node — the first Bitcoin fork, powering decentralized DNS and identity
+description: >-
+  Namecoin is a decentralized, open source information registration and transfer system based on
+  the Bitcoin cryptocurrency. It was the first fork of Bitcoin and the first to implement merged
+  mining and a decentralized DNS.
+
+
+  Namecoin Core is the reference full node implementation. Running your own Namecoin node allows
+  you to independently verify the Namecoin blockchain, register and manage .bit domain names,
+  store identity information, and transact NMC without trusting any third party.
+
+
+  Key features:
+
+  - Full blockchain validation and peer-to-peer networking
+
+  - Name registration, lookup, update, and renewal via RPC
+
+  - Built-in wallet for NMC transactions
+
+  - Merged mining support (mine NMC alongside BTC)
+
+  - Transaction index for full blockchain querying
+
+  - Configurable pruning to save disk space
+
+
+  The Namecoin blockchain is significantly smaller than Bitcoin's, making it practical to run
+  a full archival node even on modest hardware like a Raspberry Pi.
