V3 replaces the V2 staging chain. V2 balances and transactions do not carry over; start with a fresh data directory. This disposable staging chain forks public Testnet history. Use the matching revision, snapshot, and configuration below together in a separate data directory. Keep JSON-RPC bound to localhost.

Joining details captured · 2 Oct 2026, 00:36 UTC. Source: the operator's network manifest. Check it before joining; staging can reset.

1. 01
   Build the matching revision

   Use 61efe76c62645e22ca7d29a8cacfbfe77e35059a. Build with cargo build --release --locked -p zakura -p zakura-fork-miner.

2. 02
   Bootstrap the fork history

   One-time bootstrap snapshot

   Served directly by Valargroup for this staging fork. This pruned seed snapshot is not refreshed daily.

   Direct download

   Before you restoreStop your node. The commands create a new nu7-state directory; keep public Testnet and earlier staging data separate.

   Requires curl, shasum, tar, and zstd.

   curl -fL -C - -o nu7.tar.zst \
     https://api.nu7.valargroup.dev/snapshots/nu7-v3-seed-4420648.tar.zst &&
   echo 'b9d92831e7fbd7dee81471f779fde86b77146df6b49a903e26909f0de978db68  nu7.tar.zst' | shasum -a 256 -c - &&
   mkdir nu7-state &&
   tar --zstd -xf nu7.tar.zst -C nu7-state
