What is Monero pruning?

Pruning removes 7/8 of the historical blockchain data from your local storage while keeping enough to verify new transactions. A full Monero blockchain is 200GB+ (2026). A pruned blockchain is ~70GB. Pruning keeps all block headers, recent blocks (last 5,500), and 1/8 of old transaction data. The node remains a full validating node — it still verifies the entire chain — but stores less data locally.

Is a pruned node less secure?

No. A pruned node validates every block and transaction using the same rules as a full node. It stores all block headers (for chain verification) and recent blocks (for wallet syncing). The only thing missing is old transaction bodies — which are only needed for bootstrapping new nodes or researching historical data. For everyday use (sending, receiving, wallet syncing), a pruned node is identical in security to a full node.

How do I enable pruning in monerod?

Start monerod with the --prune-blockchain flag: './monerod --prune-blockchain'. This prunes the existing database on first run and keeps it pruned going forward. For a fresh sync: './monerod --prune-blockchain --sync-pruned-blocks'. To prune an existing full blockchain without re-syncing: './monero-blockchain-prune' (standalone tool, works offline). Pruning is irreversible — you can't un-prune without re-downloading the full chain.

How much disk space does pruning save?

As of 2026: Full blockchain ~200-210GB. Pruned blockchain ~65-75GB. Savings: ~130-140GB (~65% reduction). Growth rate: full adds ~25-30GB/year, pruned adds ~8-10GB/year. A 256GB SSD comfortably holds a pruned node for years. Pruning keeps 1/8 of old blocks (each node keeps a different 1/8, so the network collectively still has all data).

Should I run a full or pruned node?

Pruned node: if you have <500GB storage, want faster initial sync, and use the node for personal transactions. Full node: if you have 500GB+ storage, want to serve full blockchain data to other nodes, and want to help the network's data availability. Both verify transactions equally. For P2P trading with Haveno, a pruned node works perfectly. Most home users should run pruned — it lowers the barrier to self-sovereignty.

Monero Pruning Explained (2026)

Run your own node without needing 200GB+ of storage

TL;DR: Monero's blockchain is 200GB+. Pruning reduces it to ~70GB while maintaining full validation security. Run monerod --prune-blockchain. A 256GB SSD holds a pruned node for years. Same security as a full node — just less historical data stored locally. Run your own node for maximum privacy.

Full vs Pruned

Aspect	Full Node	Pruned Node
Storage (2026)	200-210 GB	65-75 GB
Annual growth	~25-30 GB/year	~8-10 GB/year
Validation	Full	Full
Wallet sync	Works	Works
Serve old blocks	Yes (all)	Partial (1/8)
Initial sync time	12-48 hours	6-24 hours
Minimum SSD	500 GB	256 GB
Network contribution	Maximum	Good

How Pruning Works

Monero's pruning keeps:

All block headers — needed to verify the chain of proof-of-work from genesis to present.

Recent blocks (last 5,500) — needed for wallet syncing and reorg handling.

1/8 of old transaction data — each pruned node keeps a different stripe. The network collectively retains all data.

What it removes: 7/8 of old transaction bodies that are only needed for bootstrapping new nodes from scratch.

Setup Commands

Scenario	Command
Start pruned (new sync)	`./monerod --prune-blockchain`
Sync only pruned blocks	`./monerod --prune-blockchain --sync-pruned-blocks`
Prune existing database	`./monero-blockchain-prune` (offline tool)
Pruned + Tor	`./monerod --prune-blockchain --proxy 127.0.0.1:9050`
Check if pruned	`./monerod status` (shows “pruned”)

Note: Pruning is irreversible. To get a full blockchain back, you must re-sync from scratch.

Who Should Prune?

Prune if: You have <500GB storage, want to run your own node on a laptop or small SSD, or just want the privacy benefit of not using remote nodes.

Don't prune if: You have plenty of storage and want to help the network serve full blockchain data to new nodes.

Running any node (pruned or full) is infinitely better than trusting a remote node with your transaction data.
