Clean resync (v4) — rebuild blockchain data safely

Support safety (read this first)

  • Admins/devs will not DM you first. Keep support conversations public (Telegram group / GitHub issues).
  • Never share your seed phrase, private keys, or wallet.dat with anyone.
  • Use only official download links (https://reddcoin.com / https://redd.love / https://download.reddcoin.com). Beware look‑alike sites.
  • If someone asks you to “verify” by sending coins, installing remote-control software, or sharing secrets (seed/private key), it’s a scam.
  • When sharing logs/screenshots publicly, redact personal info (paths, IPs, usernames). Do not redact block hashes needed for fork checks.
  • If you’re not sure what to back up (and where it lives), see Reference → Wallet files & locations in this knowledgebase.

Applies to: ReddCoin Core v4.22.x (desktop)

Use this when: sync is stuck, wallet is on the wrong chain, or you see database / block corruption messages.

Before you begin

  1. Close ReddCoin Core completely.
  2. Backup your wallet files to an offline location.
  3. If you see a wallets/ folder, back that up.
  4. Also back up any wallet.dat you find in the data directory.

Data folder locations

  • Windows: %APPDATA%\Reddcoin\
  • macOS: ~/Library/Application Support/Reddcoin/
  • Linux: ~/.reddcoin/

These paths were repeatedly referenced in admin troubleshooting steps. 2

Steps

Step 1 — remove blockchain state (safe)

In the data directory, delete or move aside:

  • blocks/
  • chainstate/
  • indexes/ (if present)
  • peers.dat

Then start ReddCoin Core and let it sync again.

Admin-verified

This “delete blocks/chainstate/indexes + peers.dat” pattern is the standard fix for wrong-chain and sync problems in v4. 1 2

Step 2 — optional: use the official v4 bootstrap (faster sync)

If you have slow bandwidth or limited time, you can use the v4 bootstrap:

  1. Download the v4 bootstrap from the official download host.
  2. Extract it into the data directory (it should create blocks/ and chainstate/ there).
  3. Start Core and let it finish syncing.

The Telegram support guidance points to the official v4 bootstrap directory. 2

Step 3 — last resort: clean reinstall

If you keep hitting the same failure after a clean resync:

  1. Backup wallet files again.
  2. Uninstall Core.
  3. Install the latest v4 release from the official host.
  4. Repeat Step 1.

Some users also resolved repeated sync failures by doing a clean resync and (if needed) moving between minor v4 releases. 3

When a clean resync is the right move

A clean resync is usually the right first move if you:

  • upgraded over an old v3 data directory,
  • see “wrong chain” behavior (explorer height doesn’t match),
  • see corruption warnings,
  • have persistent peer-mixing / connection problems.
