Stop a validator#

If you remove a validator, the node that is configured with the validator keys will stop producing blocks after the next pay day.

After the cool-down period, the amount that you previously staked is returned to your disposable balance at the next pay day.

If your pool has any delegators, they will be automatically moved to passive delegation, if they don’t decide to do something else.

When you’ve removed the validator, it is recommended that you also remove the keys from the node, but you should only do this after the node has stopped producing blocks, i.e. after the payday. If you want to use the node for validation at a later point in time, you’ll then have to create a new set of validator keys.

If you no longer wish to produce blocks on this account, you can stop validation.

Generate the transaction

There are two ways that you can generate the transaction:

  • Generate the transaction without signing. This option enables you to export the transaction proposal without signing it. You don’t need a LEDGER device but you do need an internet connection.

  • Generate and sign the transaction This option requires a LEDGER device and an internet connection.

In combination, these two options enable you to distribute the responsibility of creating and signing transfers among more people. You can, for example, have one person create the proposal and another one sign the proposal. It also makes it possible for you to sign the transaction on the Ledger in a different location than where the proposal was created.

Generate the transaction without signing

  2. Select Generate without signing. You can now export the proposal.

In the Desktop Wallet, you can now see Transaction details, Signatures, and Security & Submission Details, which include the status of the transaction, the identicon, and the transaction hash. If you have all the required signatures, you can submit the transaction to the chain, otherwise, you’ll have to export the proposal and receive signatures from the co-signers.

Export proposal

If more than one signature is needed to sign off on the proposal, you have to share a file of the type JSON, which contains the transaction information, with the co-signers.

  1. In the Desktop Wallet, select Export transaction proposal.

  2. Navigate to the location on your computer where you want to save the file. If you’re on Windows make sure that All Files is selected in Save as type. Give the file a name and the extension .json, and then click Save.

  3. You have to export the transaction proposal and send it to the co-signer through a secure channel. Optionally, you can also send the Identicon to the co-signers through a different secure channel.

Receive signatures from co-signers

When the co-signers have signed the transaction, they return the signed transaction proposal to you, and you have to import the files into the Desktop Wallet before you can submit the transaction to the chain.

  1. If you’re still on the same page, go to step 3. If you left the page with the account transaction, go to Multi-signature Transactions, and then select Your proposed transactions.

  2. Select the transaction that you want to submit to the chain. You can see an overview of the transaction details and an overview of the signatures. You can also see that the status of the transaction is Unsubmitted, and you can see the identicon and the transaction hash.

  3. Select Browse to file and then navigate to the location on your computer where you saved the signed transaction files. Select the relevant files, and then select OK. The files are uploaded to the Desktop Wallet and added to the list of signatures. Alternatively, you can drag and drop the signature files from their location on the computer and onto the Desktop Wallet.

Submit the transaction to the blockchain

When you have received and added all the required signatures, you can submit the transaction to the blockchain.

  1. Review the transaction details carefully to ensure that all information is correct.

  2. Select I understand this is the final submission, and that it cannot be reverted.

    If you don’t want to submit the transaction to the chain, you can select Cancel. The proposal is no longer active. However, it is still visible in the list of proposals.

  3. Select Submit transaction to chain. The transaction is submitted to the chain and finalized on the ledger.

  4. Select Finish to leave the page.

Note

If you stop as a validator, remember that this does not shut down your node. You need to shut down the node in a separate action if you no longer wish to run a node on the Concordium blockchain.
