3. When to Reboot the PlatON Process

If the present node has staked before, please check whether it has been selected as a validator (Verifying) on the Blockchain Explorer.

If so, please reboot your node after the node exits from the validator model (switch from Verifying to Active).

The command below is for reference only. You should reboot the platon process according to your own management approach.

# Check the process ID
$ ps aux |grep platon
root   13476 39.1 49.7 9174616 3925796 ?     Sl   Feb07 1140:19 /usr/bin/platon  --identity ....

# Terminate the platon node (e.g. kill 13476). In the above example, the process ID is 13476; you should replace the ID with your ID during actual operation; Once the kill command is executed, use the above ps command to check whether the process was correctly terminated before executing the following command.

$ kill <process ID>

# Activate platon node
$ nohup platon --identity platon-node --datadir ./data --port 16789  --rpcport 6789 --rpcapi "db,platon,net,web3,admin,personal" --rpc --nodekey ./data/nodekey --cbft.blskey ./data/blskey --verbosity 1 --rpcaddr --syncmode "fast" > ./data/platon.log 2>&1 &

# After rebooting, enter the console to check if the node has been upgraded to the new version:v1.4.0-unstable-e11fe5c5-20230317

$ platon attach http://localhost:6789
Welcome to the PlatON JavaScript console!

instance: PlatONnetwork/x.x.x.x/v1.4.0-unstable-e11fe5c5-20230317/linux-amd64/go1.18.10

4. Proposal Processing

  • If you have staked before, please check whether the current node is under one of the following states through the Blockchain Explorer:
    • Producing
    • Verifying
    • Active

If the current node is under one of the above three states, please refer to the following command to engage in voting. The proposal id is as follows:

< 0x9c97912c786db2e312886356e81ba79e8fb9bff43200d934d28e239f76928a54 >

# Upgrade proposal voting command (example)

$ platon_mtool vote_versionproposal --proposalid 0x9c97912c786db2e312886356e81ba79e8fb9bff43200d934d28e239f76928a54  --keystore $PLATON_MTOOLDIR/keystore/staking.json --config $PLATON_MTOOLDIR/validator/validator_config.json

If the state of a node is “Candidate”, then version declaration is required (refer to the following command).

# Version declaration (example)
$ platon_mtool declare_version --keystore $PLATON_MTOOLDIR/keystore/staking.json --config $PLATON_MTOOLDIR/validator/validator_config.json
  • If you never staked before, please skip this procedure.
  • Where $PLATON_MTOOLDIR is not defined, the absolute path should be completed according to the actual deployment.
