Setting up a Validator Node
Creating a validator
To create a validator on the network you will need to send a transaction to the network bonding / staking your FET tokens. This process registers you as a validator and if you are one of the chosen validators you will start to produce blocks.
fetchd tx staking create-validator \ --amount=<the amount to bond> \ --pubkey=$(fetchd tendermint show-validator) \ --moniker="choose a moniker" \ --chain-id=<chain_id> \ --commission-rate="0.10" \ --commission-max-rate="0.20" \ --commission-max-change-rate="0.01" \ --min-self-delegation="<the min self delegation>" \ --from=<key_name>
Before trying to create a validator you should verify that you have some tokens available beforehand. The easiest way to do this is via the CLI.
Here is an sample of a typical command line command that will register the node as running the validator.
fetchd tx staking create-validator \ --amount=1000000000000000000atestfet \ --pubkey=$(fetchd tendermint show-validator) \ --moniker="my-test-validator" \ --chain-id=stargateworld-1 \ --commission-rate="0.10" \ --commission-max-rate="0.20" \ --commission-max-change-rate="0.01" \ --min-self-delegation="1000000000000000000" \ --from=test-key
Editing a validator
Over time it is possible that validators will want to adjust various settings about their nodes. This can be simple things like the associated website for a validator or more consequential actions like altering the commission rate.
In either case, should a validator choose to make this update they would send an "edit-validator" transaction to the network. These can be created in a similar way to the "create-validator" transactions as shown below:
fetchd tx staking edit-validator --moniker="choose a moniker" \ --website="https://fetch.ai" \ --details="To infinity and beyond!" \ --chain-id=<chain_id> \ --commission-rate="0.10" --from=<key_name>
Unbonding a validator
When / if a validator wants to stop being a validator for any reason, they can unbond some or all of their staked tokens. This is done with the following command.
fetchd tx staking unbond \ <validator operator address> \ <amount to remove> \ --from <key name>
An example of the command is given in the following example:
fetchd tx staking unbond \ fetchvaloper1jqqwdch3jmzlmj4tjfn67s3sqm9elkd3wrpspf \ 1000000000000000000000atestfet \ --from test-key
Validators' obligations continue until the end of the aeon (which is typically 100 blocks or ~8 minutes depending on the configuration). It is therefore important that after a validator unbonds their stake they must leave their node up and running for 2 complete aeons before switching off. Failure to do so is treated as malicious behaviour and will result in stake being slashed.
