+# PezkuwiChain Beta Testnet Configuration
+
+This repository contains the configuration files needed to run validators 5-8 on Computer 2 for the PezkuwiChain Beta Testnet.
+
+## Contents
+
+- `chainspec/beta-testnet.json` - Raw chainspec file (5.2MB) - CRITICAL FILE
+- `scripts/` - Validator startup scripts for Computer 2 (validators 5-8)
+- `keys/` - Session keys for validators 5-8 (to be added)
+
+## Computer 1 (Bootnode + Validators 1-4)
+- IP: 172.31.134.70
+- Validators: 1, 2, 3, 4
+- Bootnode: /ip4/172.31.134.70/tcp/30333/p2p/12D3KooWLdhYkAXWWR7fFSWhMmBFgHVTf78ZWaWf2BpJxzJbTqCU
+- Genesis Hash: 0xa017f4bbea9c44b29244277ce562405a774f6555d04901c846222e3ac7e554b1
+
+## Computer 2 (Validators 5-8)
+- IP: 172.17.184.230
+- Validators: 5, 6, 7, 8
+- Ports: P2P 30337-30340, RPC 9948-9951
+
+## Setup Instructions for Computer 2
+
+### 1. Clone this repository
+```bash
+cd /home/mesut
+git clone <YOUR_PRIVATE_REPO_URL> pezkuwi-beta-config
+```
+
+### 2. Copy chainspec to SDK directory
+```bash
+cp pezkuwi-beta-config/chainspec/beta-testnet.json /home/mesut/Pezkuwi-SDK/computer1-beta-chainspec.json
+```
+
+### 3. Verify chainspec file
+```bash
+ls -lh /home/mesut/Pezkuwi-SDK/computer1-beta-chainspec.json
+# Should show: 5.2M
+```
+
+### 4. Clean old chain data (important!)
+```bash
+rm -rf /tmp/beta-validator-{5,6,7,8}
+```
+
+### 5. Make scripts executable
+```bash
+chmod +x pezkuwi-beta-config/scripts/*.sh
+```
+
+### 6. Copy scripts to SDK
+```bash
+cp -r pezkuwi-beta-config/scripts/* /home/mesut/Pezkuwi-SDK/scripts/computer2/
+```
+
+### 7. Insert validator keys (if not done already)
+```bash
+cd /home/mesut/Pezkuwi-SDK/scripts
+./insert-all-beta-keys.sh
+```
+
+### 8. Start all validators
+```bash
+cd /home/mesut/Pezkuwi-SDK/scripts/computer2
+./start-all-validators-computer2.sh
+```
+
+### 9. Verify validators are running
+```bash
+# Check processes
+ps aux | grep pezkuwi
+
+# Check logs
+tail -f /tmp/beta-validator-5.log
+tail -f /tmp/beta-validator-6.log
+tail -f /tmp/beta-validator-7.log
+tail -f /tmp/beta-validator-8.log
+```
+
+### 10. Stop validators (if needed)
+```bash
+cd /home/mesut/Pezkuwi-SDK/scripts/computer2
+./stop-validators-computer2.sh
+```
+
+## Expected Behavior
+
+Once all 8 validators are running:
+- Each validator should show 7 peers (connected to all other validators)
+- Genesis hash should match: 0xa017f4bbea9c44b29244277ce562405a774f6555d04901c846222e3ac7e554b1
+- Block production should begin (requires minimum 6 validators for BFT consensus)
+- Logs should show: "Prepared block for proposing"
+
+## Troubleshooting
+
+### Genesis hash mismatch
+- Ensure chainspec file is exactly 5.2MB
+- Re-copy from this repository
+- Clean chain data: `rm -rf /tmp/beta-validator-{5,6,7,8}`
+
+### 0 peers
+- Verify Computer 1 validators are running
+- Check bootnode is accessible: `telnet 172.31.134.70 30333`
+- Verify IP addresses are correct in scripts
+
+### Keys not found
+- Re-run key insertion: `./insert-all-beta-keys.sh`
+- Check RPC ports are correct (9948-9951)
+
+## Important Files
+
+- DO NOT modify the chainspec file - it must match Computer 1 exactly
+- Session keys are stored in validator base paths: /tmp/beta-validator-{5,6,7,8}
+- Seed phrases are stored separately (NOT in this repository)
+
