# XDPoS Consensus Testing Guide
This document describes how to test the XDPoS consensus implementation for syncing with XDC Mainnet and Apothem Testnet.
## Prerequisites
- Go 1.21 or higher
- Git
- At least 500GB disk space for full sync (mainnet)
- Good network connection
## Building
```bash
# Clone the repository
git clone https://github.com/AnilChinchawale/go-ethereum.git
cd go-ethereum
git checkout feature/xdpos-consensus
# Build the XDC binary
make XDC
# Or build all tools
make all
```
## Network Configuration
### XDC Mainnet
- **Chain ID:** 50
- **Network ID:** 50
- **Block Time:** 2 seconds
- **Epoch:** 900 blocks (~30 minutes)
- **Consensus:** XDPoS (Delegated Proof of Stake)
- **P2P Port:** 30304 (default for XDC)
### XDC Apothem Testnet
- **Chain ID:** 51
- **Network ID:** 51
- **Block Time:** 2 seconds
- **Epoch:** 900 blocks (~30 minutes)
## Running a Node
### Full Sync (XDC Mainnet)
```bash
# Initialize with genesis (first time only)
./build/bin/XDC init genesis/xdc_mainnet.json --datadir ~/.xdc
# Start sync
./build/bin/XDC \
--networkid 50 \
--datadir ~/.xdc \
--syncmode full \
--port 30304 \
--bootnodes "enode://91e59fa1b034ae35e9f4e8a99cc6621f09d74e76a6220abb6c93b29ed41a9e1fc4e5b70e2c5fc43f883cffbdcd6f4f6cbc1d23af077f28c2aecc22403355d4b1@81.0.220.137:30304,enode://91e59fa1b034ae35e9f4e8a99cc6621f09d74e76a6220abb6c93b29ed41a9e1fc4e5b70e2c5fc43f883cffbdcd6f4f6cbc1d23af077f28c2aecc22403355d4b1@5.189.144.192:30304,enode://91e59fa1b034ae35e9f4e8a99cc6621f09d74e76a6220abb6c93b29ed41a9e1fc4e5b70e2c5fc43f883cffbdcd6f4f6cbc1d23af077f28c2aecc22403355d4b1@154.53.42.5:30304"
```
### Light Sync
```bash
./build/bin/XDC \
--networkid 50 \
--datadir ~/.xdc-light \
--syncmode light \
--port 30305 \
--bootnodes "enode://91e59fa1b034ae35e9f4e8a99cc6621f09d74e76a6220abb6c93b29ed41a9e1fc4e5b70e2c5fc43f883cffbdcd6f4f6cbc1d23af077f28c2aecc22403355d4b1@81.0.220.137:30304"
```
### Apothem Testnet
```bash
# Initialize with genesis
./build/bin/XDC init genesis/xdc_apothem.json --datadir ~/.xdc-testnet
# Start sync
./build/bin/XDC \
--networkid 51 \
--datadir ~/.xdc-testnet \
--syncmode full \
--port 30304
```
## Verifying Sync
### Check Sync Status
```bash
# Attach to running node
./build/bin/XDC attach ~/.xdc/XDC.ipc
# In console
> eth.syncing
> eth.blockNumber
> admin.peers
```
### Expected Output
A syncing node should show:
```javascript
> eth.syncing
{
currentBlock: 1234567,
highestBlock: 9876543,
knownStates: 0,
pulledStates: 0,
startingBlock: 0
}
> admin.peers.length
5 // Should have several peers
```
### Check Consensus
```javascript
// Get current block
> eth.getBlock("latest")
// Verify XDPoS fields
> eth.getBlock("latest").difficulty
2 // Should be 1 or 2 (in-turn/out-of-turn)
// Check block time
> eth.getBlock("latest").timestamp - eth.getBlock(eth.blockNumber - 1).timestamp
2 // Should be ~2 seconds
```
## RPC Endpoints
Enable RPC for external access:
```bash
./build/bin/XDC \
--networkid 50 \
--datadir ~/.xdc \
--http \
--http.addr "0.0.0.0" \
--http.port 8545 \
--http.api "eth,net,web3,xdpos" \
--http.corsdomain "*" \
--ws \
--ws.addr "0.0.0.0" \
--ws.port 8546 \
--ws.api "eth,net,web3,xdpos"
```
## XDPoS-Specific APIs
The XDPoS consensus engine exposes additional RPC methods:
```javascript
// Get current masternodes
> xdpos.getMasternodes()
// Get snapshot at specific block
> xdpos.getSnapshot(blockNumber)
// Check if address is a masternode
> xdpos.isValidMasternode(address)
// Get signers for a specific block
> xdpos.getSigners(blockNumber)
```
## Troubleshooting
### No Peers
1. Check firewall allows port 30304 (TCP/UDP)
2. Verify bootnodes are reachable: `nc -vz 81.0.220.137 30304`
3. Try adding more bootnodes from the network
### Sync Stalled
1. Check disk space: `df -h`
2. Check memory usage: `free -m`
3. Restart with `--cache 4096` for more caching
### Genesis Mismatch
If you see "genesis block mismatch" errors:
```bash
# Remove old data and reinitialize
rm -rf ~/.xdc/XDC
./build/bin/XDC init genesis/xdc_mainnet.json --datadir ~/.xdc
```
### Block Validation Errors
Check logs for specific errors:
```bash
./build/bin/XDC --verbosity 4 ... # Enable debug logging
```
Common issues:
- **"unauthorized"**: Block signer not in masternode list
- **"invalid difficulty"**: Difficulty calculation mismatch
- **"invalid timestamp"**: Block time too close to parent
## Known Limitations
### Current Implementation Status
1. **Reward Distribution**: Basic implementation - distributes rewards at epoch checkpoints
2. **Penalty System**: Tracks missed blocks, penalizes inactive masternodes
3. **Contract Integration**: Hook system in place for validator contract calls
4. **Double Validation**: Signature verification implemented
### What's Working
- ✅ Basic block validation
- ✅ Signature recovery
- ✅ Epoch transitions
- ✅ Masternode list from checkpoint headers
- ✅ Difficulty calculation
- ✅ Block sealing
### Needs Live Network Testing
- ⚠️ Smart contract state sync (0x88 validator contract)
- ⚠️ Full reward distribution with voter rewards
- ⚠️ Cross-epoch penalty persistence
- ⚠️ Network sync with production bootnodes
## Performance Tuning
For production deployments:
```bash
./build/bin/XDC \
--networkid 50 \
--datadir /data/xdc \
--syncmode full \
--cache 8192 \
--maxpeers 100 \
--txpool.globalslots 16384 \
--txpool.globalqueue 4096
```
## Security Considerations
1. **RPC Access**: Never expose RPC without authentication in production
2. **Key Storage**: Use hardware wallets or encrypted keystores for masternodes
3. **Firewall**: Only allow necessary ports (30304 for P2P, 8545/8546 for RPC if needed)

## Reporting Issues
If you encounter issues:
1. Enable debug logging: `--verbosity 5`
2. Capture logs around the error
3. Note the block number where it failed
4. Open an issue with logs and system info
