• macOS: ~/Library/Application Support/Zclassic/
• Linux: ~/.zclassic/

⚠️ Important Notes

1. ALWAYS backup your wallet.dat before using this bootstrap
2. The bootstrap does NOT contain your wallet - your funds are safe
3. After extracting, your node will sync the remaining blocks (usually minutes)
4. Verify checksums to ensure file integrity
5. Compatible with Zclassic Core 1.x and ZPay wallet

🔧 Troubleshooting

Bootstrap doesn't work

• Make sure zclassicd is fully stopped before extracting
• Verify checksums match
• Ensure you have enough disk space (~20 GB free)

Node won't start after bootstrap

• Check zclassic debug.log: tail -f ~/.zclassic/debug.log
• Try running with -reindex flag: zclassicd -daemon -reindex

"Corrupted block database" error

• Remove blocks and chainstate: rm -rf ~/.zclassic/blocks ~/.zclassic/chainstate
• Extract bootstrap again
• Start with -reindex
