Clear Remote WNS

To clear a remote WNS, the following information is required:

• The RPC endpoint of the remote WNS (e.g. see https://github.com/wirelineio/dxns#testnets).
• The mnemonic for an account that has funds on the WNS.

The following example will work for https://wns-testnet.dev.wireline.ninja/console.

Create an account on a different machine (e.g. laptop/desktop), using the mnemonic for the remote root account.

$ wnscli keys add root-testnet-dev --recover
# Enter a passphrase for the new account, repeat it when prompted.
# Use the following mnemonic for recovery:
# salad portion potato insect unknown exile lion soft layer evolve flavor hollow emerge celery ankle sponsor easy effort flush furnace life maximum rotate apple

Clear the remote WNS using the following command:

$ wnscli tx nameservice clear --from root-testnet-dev --node tcp://wns-testnet.dev.wireline.ninja:26657
# Enter passphrase when prompted.

Use the GQL playground (https://wns-testnet.dev.wireline.ninja/console) to query and confirm that all records are gone.

Invariant Checking

To turn on invariant checking, pass the inv-check-period flag to the server.

# Check invariants every N (here, N=1) blocks.
$ wnsd start --gql-server --gql-playground --inv-check-period=1

Export State

• Halt the chain.
• Run wnsd export > state.json.
• state.json contains the state of all modules (e.g. records and bonds).

Import State

• Reset the chain state using wnsd unsafe-reset-all.
• Replace ~/.wire/wnsd/config/genesis.json with a previously exported state (e.g. state.json).
• Start the chain.

Denominations/Units

• wire // 1 (base denom unit).
• mwire // 10^-3 (milli).
• uwire // 10^-6 (micro).

Also see x/bond/internal/types/init.go.

Module Accounts

• bond: Module account for bonds. Balance reflects current total bonded amount.
• record_rent: Module account for record rent collection. Distribution of proceeds from rent collection (to be implemented) will reduce this amount.

$ wnscli query bond balance
{
  "bond": [
    {
      "denom": "uwire",
      "amount": "5993000000"
    }
  ],
  "record_rent": [
    {
      "denom": "uwire",
      "amount": "7000000"
    }
  ]
}
