Tachyon 2.0

Quick Overview

Attribute	Value
Validator Version	tachyon-validator: v2.0.21
Restart Slot	48853558
Shred Version	41710
Bank Hash	BNd9PkMbZmEHGeErE6amj9Fb3phG5BsPH4FFbQfa2dVx

During the restart and migration to v2.0, the testnet will undergo a fork. A new snapshot and genesis will be created, and the network will restart using the updated version.

To streamline the process, all stake accounts will be deactivated, requiring stakers to re-delegate their accounts upon rejoining the network. Rest assured, the original stake amounts will be preserved.

Follow the steps below to migrate your validator to v2.0.

---

Step 1: Install Tachyon v2.0

You will need Tachyon v2.0 to generate the correct snapshot.

1. Clone the Tachyon repository:

   git clone https://github.com/x1-labs/tachyon.git

2. Build the repository:

   cd tachyon
   cargo build --release

3. Update your PATH environment variable:

   Replace /path/to/tachyon with the correct path. Use pwd to get your current directory path.

   export PATH=$PATH:/path/to/tachyon/target/release

   📌 Tip: Add this line to your ~/.bashrc or ~/.zshrc to make the change permanent.

4. Verify the installation:

   tachyon-validator --version

   You should see the following output:

   tachyon-validator 2.0.21 (src:00000000; feat:2908148756, client:Tachyon)

---

Step 2: Stop the Solana Validator

If your validator is still running, stop it before proceeding.

Step 3: Backup Your Data and Remove the Old Ledger

1. Backup your keys 🗝️: Save your validator keys in a secure location.

2. Backup or remove your old ledger directory:

   • If you have sufficient disk space, keep the old ledger as a backup.

   • Otherwise, you can delete it to free up space.

   Note: Replace paths with your actual ledger directory and backup location.

   # Move the ledger to a backup location
   mv /home/ubuntu/ledger /path/to/backup/location
   
   # Or delete the ledger
   rm -rf /home/ubuntu/ledger

---

Step 4: Update Startup Configuration

1. Update the binary name in your startup script:

   Rename from solana-validator to tachyon-validator

    tachyon-validator

See the example start script here.

Step 5: Start your validator

1. Start your validator using the updated configuration.

2. Make sure your validator is in sync with the network:

   solana catchup --our-localhost

   You should see the following output:

   XXXXXXXXXXXXXXXXXXXXXXXXXX has caught up (us:XXXXXXXX them:XXXXXXXX)

---

Step 6: Re-delegate Your Stake

⚠️ Warning: Do not re-delegate your stake accounts until you're fully synced with the network.

After the restart, you will need to re-delegate your stake accounts. Your original stake amounts will be preserved.

Note: Replace paths with the correct paths to your identity, stake, and vote account files.

solana -k ~/identity.json delegate-stake ~/stake-account.json ~/vote-account.json

📌 Tip: Your stake will take a few epochs to activate and gradually grow to its full amount.

Next Steps

• Check the logs to ensure your validator is running correctly.

• Use the solana validators command to verify your validator's status.

• Monitor the network and assist others during the migration process.
