Pruning
Short answer: Pruning cuts blockchain storage needs by discarding spent transaction data while keeping cryptographic proofs. See how much space it actually saves.
Definition
Pruning is a technique that reduces blockchain storage requirements by discarding spent transaction outputs while maintaining cryptographic proofs. Pruned nodes can still validate new transactions but cannot serve full historical data to other nodes.
Technical Explanation
Once a UTXO is spent, its full data is no longer needed for validation—only proof it existed. Pruned nodes keep block headers, unspent outputs, and recent blocks while discarding spent transaction details. This can reduce storage from hundreds of gigabytes to under 10GB.
Tradeoffs: pruned nodes cannot help new nodes sync from genesis or provide historical data for block explorers. The network needs enough archival nodes to maintain full history while pruning enables wider participation.
SynX Relevance
SynX supports optional pruning for nodes with limited storage. Users can run fully-validating nodes on modest hardware while archival nodes maintained by the community preserve complete history. Accessibility without compromising network integrity.
Frequently Asked Questions
- Is a pruned node less secure?
- No—pruned nodes fully validate all rules; they just don't store unnecessary history.
- How much storage does pruning save?
- Significant savings—potentially 90%+ depending on chain history length.
- Can I serve blocks to other nodes while pruned?
- Only recent blocks; you cannot help nodes sync from genesis.
