Service Node Operation

This page explains how to go about common Service Node operations such as staking, voting, updating, restarting, and checking your Service Node configs. For instructions on setting up a Service Node, see the Service Node Setup Guide.

Service Node Staking

To stake your Service Node collateral, you can enable staking as you normally would. The inputs used for your Service Node collateral are all tracked, so when you "hit" a stake and it generates a new input it will auto-register for you to keep the Service Node active.

After a stake, the Service Node is still active for all existing clients, but will be inactive for new clients until the 2 confirmations are complete.

Note: If you register the Service Node from a collateral wallet then import the Service Node's BLOCK address to another machine for staking, the Service Node will go offline. Make sure you register the Service Node (servicenoderegister) from the machine that will be staking so that it will know to auto-register on stake.

Check Service Node Status

  1. On the SNode wallet you can use servicenodestatus.
  2. On the Collateral wallet you can use servicenodelist.
  3. If you're using the command line you can filter the list with blocknet-cli servicenode list | sed -n '/"snodekey": "#####/,/},/p', replacing ##### with your Service Node's snodekey. Example: 
    ./blocknet-cli servicenode list | sed -n '/"snodekey": "\(0b38bfac90cc5c683b6a27f952b2346a1009fc0f9c1a0790809f185ab27b14ecc6\)/,/},/p
  4. You can also filter for multiple Service Nodes by separating each snodekey with \|. Example: 
    ./blocknet-cli servicenode list | sed -n '/"snodekey": "\(#####\|#####\|#####\)/,/},/p

Updated Your Blocknet Wallets

If you have just updated your Collateral Computer wallet and SNode Computer wallet, follow these instructions:

  1. Open the Collateral Computer wallet and let it sync.
  2. Open the SNode Computer wallet and let it sync.
  3. From the Collateral Computer wallet, re-register the node with the servicenoderegister command.
  4. From the SNode Computer wallet, send the network ping with servicenodesendping.

Restarted Your SNode Computer Wallet

If you have just restarted your SNode Computer wallet, follow these instructions:

  1. Open the SNode Computer wallet and let it sync.
  2. From the SNode Computer, check if your Service Nodes status still shows "running" with the servicenodestatus command.
  3. If they show "status": "running" then you don't need to do anything. If they show "offline" then continue.
  4. From the Collateral Computer wallet, re-register the node with the servicenoderegister command.
  5. From the SNode Computer wallet, send the network ping with servicenodesendping.

Restarted Your Collateral Computer Wallet

If you have just restarted your Collateral Computer wallet you don't need to do anything.

Updated Your SNode Computer blocknet.conf

If you have just updated the blocknet.conf on your SNode Computer wallet, follow these instructions:

  1. Restart the SNode Computer wallet and let it sync.
  2. Open the Collateral Computer wallet and let it sync.
  3. From the SNode Computer, check if your Service Nodes status still shows "running" with the servicenodestatus command.
  4. If they show "status": "running" then you don't need to do anything. If they show "offline" then continue.
  5. From the Collateral Computer wallet, re-register the node with the servicenoderegister command.
  6. From the SNode Computer wallet, send the network ping with servicenodesendping.

Updated Your SNode Computer xbridge.conf

If you have just updated the xbridge.conf on your SNode Computer wallet, follow these instructions:

  1. Add the blockchains you want to add trading support for in the ExchangeWallets= entry in xbridge.conf, denoted by the chain's asset's ticker. Separate each wallet name with a comma (no space). You can keep the rest of the configuration body the same, only the ExchangeWallets= setting needs to be updated (unless adding new support).
  2. Example: ExchangeWallets=BLOCK,LTC,BTC,SYS,DGB
  3. Restart the Blocknet wallet or use the dxLoadXBridgeConf command (from either the Debug Console or the command line) to load the updated settings.
  4. Use servicenodesendping to propogate these new settings to the network immediately or wait up to 3 minutes for this to happen automatically.
  5. You can view the blockchains you are supporting with the dxGetLocalTokens command.

Updated XRouter Services or Configs

If you have just updated the xrouter.conf on your SNode Computer wallet, follow these instructions:

  1. Add the chains you want to support SPV calls for in the wallets= entry in xrouter.conf, denoted by the chain's asset's ticker. Separate each wallet name with a comma.
  2. Example: wallets=SYS,BLOCK,BTC,ETH,MNP
  3. If you added or removed blockchain support, make sure to also update the rpcthreads= value in the blocknet.conf file.
  4. Use xrReloadConfigs to load your newly configured settings to xrouter.conf without needing to restart your Service Node.
  5. Use servicenodesendping to propogate these new settings to the network immediately or wait up to 3 minutes for this to happen automatically.
  6. You can view your configs using xrStatus.

Updated XCloud Services or Plugin Files

If you have just updated your XCloud services or plugin files, follow these instructions:

  1. Add the service name to the plugins= entry in xrouter.conf. The service name listed must be the exact name of your config file without the file extension. Separate each service name with a comma.
    • Example: If you had 3 services that you wanted to deploy with config names eth_getBalance.conf, eth_blockNumber.conf, and weatherData.conf, the plugins= setting would read as follows: plugins=eth_getBalance,eth_blockNumber,weatherData
  2. Use xrReloadConfigs to load your newly configured settings to xrouter.conf without needing to restart your Service Node.
  3. Use servicenodesendping to propogate these new settings to the network immediately or wait up to 3 minutes for this to happen automatically.
  4. You can view your configs using xrStatus (See example output).
  5. Post your services to the forum so others can discover, learn more, and find instructions on how to interact with your service.

View Your XRouter or XCloud Configs

You can view your configs using xrStatus. This returns your SPV wallets, SPV calls and settings, plugin calls and settings, and the raw text of your xrouter.conf file. See usage details in the API Docs

Check the Wallet and Protocol Versions

You can view the wallet version and blockchain, XBridge, XRouter protocol versions using the getblockchaininfo command. See usage details in the API Docs
