⁠Algorand Mainnet Participation Node on Flux Cloud

Deploy and run a fully-synced Algorand mainnet participation node on decentralized Flux Cloud infrastructure at a fraction of traditional cloud costs.

⁠🌟 Overview

This deployment uses the official Algorand Foundation Docker image to run a participation node that:

• Participates in Algorand's Pure Proof of Stake (PPoS) consensus
• Validates transactions and proposes blocks
• Contributes to network security and decentralization
• Runs 24/7 on distributed Flux infrastructure

Cost Comparison:

• Traditional Cloud (AWS/GCP): ~$80-100/month
• Flux Cloud: ~$7-10/month (60 FLUX)

⁠📋 Prerequisites

Before deploying, you'll need:

1. Flux Cloud Account

   • Sign up at https://cloud.runonflux.com/⁠
   • Fund account with FLUX tokens or use credit card

2. Pera Wallet (for signing participation transactions)

   • Download: https://perawallet.app/⁠
   • Create or import an Algorand wallet
   • Fund with at least 1 ALGO for transaction fees

3. ALGO Tokens (optional, for rewards)

   • Minimum 30,000 ALGO required to receive block rewards
   • Any amount can participate without rewards (testing/network support)

⁠🚀 Deployment Steps

⁠Step 1: Deploy on Flux Cloud

1. Go to https://cloud.runonflux.com/marketplace/⁠
2. Search for "Algorand" or find the Algorand Mainnet Node
3. Click "Deploy"
4. Configure deployment:
   • Name: algorand-mainnet-node (or your preferred name)
   • Docker Image: mochanerd/algorand-node-mainnet:latest
   • CPU: 8 cores
   • RAM: 16GB
   • Storage: 120GB (SSD/NVMe recommended)
   • Ports: 8080 (algod API), 4001 (P2P)
5. Complete payment and wait for deployment (5-10 minutes)

Monthly Cost: 60 FLUX ($7-10 USD)

Recommended Specifications:

• CPU: 8 cores (for optimal block processing)
• RAM: 16GB (handles blockchain operations efficiently)
• Storage: 120GB SSD/NVMe (blockchain data ~100GB + overhead)
• Network: 1 Gbps connection recommended

⁠Step 2: Access Your Node

Once deployed, you'll receive:

• Container access URL
• SSH/terminal access to the container
• API endpoint for algod

Access the container terminal:

# Via Flux Cloud dashboard or SSH
ssh root@<your-flux-node-ip>

⁠Step 3: Wait for Blockchain Sync

The node needs to sync with Algorand mainnet before participating.

Check sync status:

goal node status

Look for:

• Sync Time: 0.0s (fully synced)
• Catchpoint: shows catchpoint progress if syncing

Note: Initial sync can take 2-4 hours depending on network speed.

⁠Step 4: Generate Participation Keys

Once synced, generate participation keys for your wallet address.

Get current round number:

goal node status

Note the Last committed block: number (e.g., 57632000)

Calculate validity period:

• 6 months ≈ 4,778,000 rounds
• 1 year ≈ 9,556,000 rounds

Generate keys:

goal account addpartkey
  -a <YOUR_ALGORAND_ADDRESS>
  --roundFirstValid <CURRENT_ROUND>
  --roundLastValid <CURRENT_ROUND + 4778000>

Example:

goal account addpartkey 
  -a 54XEVK24Q5MTXN76WQRYUBZJDS2RX3TS77XEYUKUEQZZY64R2GFHJXSJF4 
  --roundFirstValid 57632072 
  --roundLastValid 62410287

Save the Participation ID displayed in the output.

View participation key details:

goal account partkeyinfo

Save these values (you'll need them for TxnDuck):

• Selection key (base64)
• Voting key (base64)
• State proof key (base64)
• Key dilution (number)

⁠Step 5: Create Online Transaction

Generate unsigned transaction:

goal account changeonlinestatus 
  -a <YOUR_ALGORAND_ADDRESS> 
  -o=1 
  --txfile=online.txn

Convert to base64:

base64 -w 0 online.txn

Copy the entire base64 output (long string).

⁠Step 6: Sign Transaction with TxnDuck + Pera Wallet

Option A: Use TxnDuck Compose (Recommended)

1. Go to https://txnduck.vercel.app/en/txn/compose?preset=reg_online⁠

2. The form will have these fields:

   • Sender: Paste your Algorand address
   • Voting key: From goal account partkeyinfo output
   • Selection key: From goal account partkeyinfo output
   • State proof key: From goal account partkeyinfo output
   • First voting round: Your start round
   • Last voting round: Your end round
   • Voting key dilution: From goal account partkeyinfo (usually ~2186)

3. Click "Connect Wallet" → Select "Pera Wallet"

4. TxnDuck will open WalletConnect QR code

5. Open Pera Wallet on your phone → Scan QR code

6. Review transaction details in Pera Wallet:

   • Type: Key Registration
   • Sender: Your address
   • Fee: ~0.001 ALGO

7. Sign the transaction in Pera Wallet

8. Click "Send Transaction" in TxnDuck

9. Transaction will broadcast to network

Option B: Use Pre-Generated Transaction

1. Go to https://txnduck.vercel.app/⁠
2. Click "Decode Transaction"
3. Paste your base64 transaction from Step 5
4. Click "Connect Wallet" → "Pera Wallet"
5. Scan QR code with Pera Wallet
6. Sign and broadcast

⁠Step 7: Verify Node is Online

Wait 1-2 minutes for the transaction to confirm.

Check participation status:

goal account listpartkeys

You should see:

Registered  Account      ParticipationID   Last Used  First round  Last round
yes         <YOUR_ADDR>  <PART_ID>         N/A        57632072     62410287

Verify online status:

goal account dump -a <YOUR_ALGORAND_ADDRESS>

Should show: "status": "Online"

Check logs for consensus activity:

tail -f /var/lib/algorand/node.log

Look for:

• BlockAccepted - Node accepting blocks
• ProposalAccepted - Receiving block proposals
• RoundStart - Processing consensus rounds

⁠🎯 Staking Rewards (Optional)

To receive block rewards, your account needs:

• Minimum 30,000 ALGO stake
• 2 ALGO transaction fee when registering (marks account as "incentive-eligible")

Register for rewards:

goal account changeonlinestatus
  -a <YOUR_ALGORAND_ADDRESS> 
  -o=1 
  --fee=2000000 
  --txfile=online_rewards.txn

Then sign with TxnDuck + Pera Wallet (same process as Step 6).

Current Rewards (as of Jan 2025):

• 10 ALGO per block proposed (decays 1% per million blocks)
• 50% of transaction fees from blocks you propose
• Probabilistic based on your stake percentage

⁠📊 Monitoring Your Node

Check node status:

goal node status

View participation keys:

goal account listpartkeys

Check account information:

goal account dump -a <YOUR_ALGORAND_ADDRESS>

Monitor consensus logs:

tail -f /var/lib/algorand/node.log | grep Agreement

View recent blocks:

goal node lastround

⁠🔧 Maintenance

Renew Participation Keys (before expiration):

1. Generate new keys 1-2 weeks before current keys expire
2. Sign new key registration transaction
3. Old keys automatically expire, new keys take effect

Update Node Software:

The Docker container automatically updates to the latest Algorand release. Monitor Flux Cloud dashboard for container restarts.

Extend Participation:

To extend beyond initial 6 months:

goal account addpartkey 
  -a <YOUR_ALGORAND_ADDRESS> 
  --roundFirstValid <CURRENT_EXPIRY_ROUND> 
  --roundLastValid <NEW_EXPIRY_ROUND>

Then sign new transaction with TxnDuck + Pera Wallet.

⁠❓ Troubleshooting

Node not syncing:

goal node status
# Check "Sync Time" and "Catchpoint"
# Wait 2-4 hours for initial sync

Participation keys not showing as registered:

goal account listpartkeys
# Verify transaction confirmed on chain
# Check https://algoexplorer.io/tx/<TRANSACTION_ID>

Account showing "Offline":

goal account dump -a <YOUR_ALGORAND_ADDRESS>
# If status is "Offline", transaction may not have confirmed
# Wait 1-2 minutes and check again

Connection issues:

goal node status
# Check "Genesis ID" should be "mainnet-v1.0"
# Verify ports 8080 and 4001 are accessible
