Network Information

This page provides essential network information for connecting to Viction mainnet and testnet.

Network IDs

Viction operates two public networks:

Mainnet

Network ID: 88
Chain ID: 88
Currency Symbol: VIC
Currency Decimals: 18
Block Explorer: https://vicscan.xyz

Testnet

Network ID: 89
Chain ID: 89
Currency Symbol: VIC
Currency Decimals: 18
Block Explorer: https://testnet.vicscan.xyz

Network ID and Chain ID are identical for both networks, making EIP-155 replay protection straightforward.

  --ws --wsaddr 127.0.0.1 --wsport 8546 \
  --syncmode "full" --gcmode "full"

Docker Setup

Mainnet

docker run -d --name viction-mainnet \
  -v "$PWD/data:/tomochain/data" \
  -v "$PWD/keystore:/tomochain/keystore" \
  -p 8545:8545 -p 8546:8546 -p 30303:30303 \
  -e NETWORK_ID=88 \
  buildonviction/node:latest

Testnet

docker run -d --name viction-testnet \
  -v "$PWD/data-testnet:/tomochain/data" \
  -v "$PWD/keystore:/tomochain/keystore" \
  -p 8545:8545 -p 8546:8546 -p 30303:30303 \
  -e NETWORK_ID=89 \
  buildonviction/node:latest

Sync Modes

Full Sync (Recommended):

--syncmode "full" --gcmode "full"

Downloads all blocks and executes all transactions
Prunes old state data (keeps last ~90 epochs)
Suitable for most use cases
Requires ~200GB storage

Archive Sync:

--syncmode "full" --gcmode "archive"

Keeps complete historical state
Required for block explorers and some analytics
Requires 1TB+ storage and grows continuously

Light Sync (Experimental):

--syncmode "light"

Only downloads block headers
Minimal storage and bandwidth
Limited functionality
Not recommended for production

Gas Configuration

Gas Prices

From params/protocol_params.go:

const (
    MinGasLimit          uint64 = 5000
    TomoGenesisGasLimit  uint64 = 84000000
    TxGas                uint64 = 21000  // Base transaction cost
    TxGasContractCreation uint64 = 53000  // Contract creation cost
)

Recommended Gas Settings

Standard Transfer:

Gas Limit: 21,000
Gas Price: 250 Gwei (0.00000025 VIC)
Total Cost: ~0.00525 VIC

Contract Interaction:

Gas Limit: 100,000 - 500,000 (depends on complexity)
Gas Price: 250 Gwei
Total Cost: 0.025 - 0.125 VIC

Contract Deployment:

Gas Limit: 1,000,000+ (depends on contract size)
Gas Price: 250 Gwei
Total Cost: 0.25+ VIC

Viction’s gas prices are significantly lower than Ethereum, making it cost-effective for frequent transactions and complex contracts.

Network Ports

Standard Ports

30303: P2P network communication (TCP & UDP)
8545: HTTP JSON-RPC interface
8546: WebSocket JSON-RPC interface

Firewall Configuration

For a full node:

# Allow P2P connections
sudo ufw allow 30303/tcp
sudo ufw allow 30303/udp

# RPC/WS should be restricted to localhost or trusted IPs
# Do not expose to internet!

For a masternode:

# Only P2P port should be publicly accessible
sudo ufw allow 30303/tcp
sudo ufw allow 30303/udp

# RPC/WS restricted to localhost
sudo ufw deny 8545/tcp
sudo ufw deny 8546/tcp
