Dune Specific Operations

Dune Network provides three additionnal operations: * Manage_account to manage the parameters of an account * Activate_protocol to change the protocol or its constants * Manage_accounts to manage multiple accounts

The first operation can be used by any account. The two other operations can only be used by a superadmin account.

The Manage_account operation

The Manage_account operation is used to change the parameters of a particular account, or to perform an action on behalf of that account. If the account has an administrator (admin), the administrator must sign the operation, unless it is a smart contract.

JSON Format

The content of the operation is a JSON file containing some of the following fields (missing fields are interpreted as unchanged):

• maxrolls is either an integer or null, and specifies the maximal number of rolls that a baker wants to have;
• admin is either another contract or null, and specifies the contract that should be used to administrate the account. Once administrated, the admin key must be used to send the Manage_account operation.
• white_list is a list of contracts that are the only ones that can receive transfers. An empty list means that transfers are allowed to all accounts.
• delegation is a boolean, and specifies whether new delegations to this account are allowed (true, the default) or forbidden (false).
• recovery is either another contract or null, and specifies a contract that can be used to recover all the tokens from this account. The recovery account is usually kept in cold storage, and only used if the key of the account is lost.
• actions is a list of pairs, containing the name of the action and an argument.

Available Actions

The following actions are currently available:

• clear_delegations: this action takes an empty argument, and clear all the accounts delegated to this contract, which must be a baker. This action can be used by a baker stopping its services.
• move_delegations: this action takes another baker account, and transfers all delegations to the current account to the other baker account. This action can be used by a baker changing its baking key.
• recover_account: this actions takes another account, whose recovery account is the current account. The full balance of the other account is transferred to the current account, and the account is deleted.

Example of JSON file

The following JSON file gives an example of values for all the fields managed by Manage_account:

{
  "maxrolls": 100,
  "admin": "dn1XXX...",
  "white_list": [ "dn1XXX..." , "dn1XXX..." ],
  "delegation": false,
  "recovery": "dn1XXX...",
  "actions": [
     [ "clear_delegations", null ],
     [ "move_delegations", { "addr": "dn1XXX..." } ],
     [ "recover_account", { "addr": "dn1XXX..." } ]
  ]
}

Inject with dune-client

The following command can be used to inject a Manage_account operation:

dune-client dune change account parameters JSONFILE of ACCOUNT with admin ACCOUNT

The following command can be used to get the current values (except the actions field):

dune-client dune get account parameters for ACCOUNT

The section on Baker Account Management contains other commands that can be used to set most of the fields, one by one.

The Activate_protocol operation

The Activate_protocol operation is used to activate a new protocol, or change the constants of the protocol. It can also be used to trigger specific protocol actions. All of these changes are scheduled to happen at a given level, at the end of the block construction. This operation can only be used by a Superadmin Account (Network Administration) account.

Operation Contents

The operation contains:

• The level at which the change should happen (at the end of the block construction);
• The optional hash of a new protocol
• An optional set of protocol parameters

The protocol parameters (specified in a JSON file) can contain:

• New values for the protocol constants
• An optional protocol_revision to trigger a change of protocol revision. Even protocol revisions are reserved for stable upgrades, while odd protocol revisions are used for testing purposes. Typically, new features are available in the next branch with the latest stable protocol revision + 1.
• A list of protocol_actions

Currently available protocol actions are:

• The freeze_undelegated_accounts action can be used to iter on all contracts and freeze undelegated accounts for at least 60 cycles;
• The burn_all_commitments action can be used to remove all commitments (blinded key hashes with corresponding duns, which are burnt during the operation);
• The activate_burn_legacy action can be used to start burning undelegated burnable accounts;
• The deactivate_burn_legacy action can be used to stop burning undelegated burnable accounts;

Inject with dune_client

To inject the Activate_protocol operation, the following command can be used:

dune-client dune activate protocol PROTOCOL_HASH with key SUPERADMIN and parameters JSONFILE at level LEVEL

To only change the parameters, the following command can be used:

dune-client dune change parameters JSONFILE with key SUPERADMIN at level LEVEL

If a protocol activation has been scheduled, the following command can be used to get the upcoming change:

dune-client dune get activate protocol

The following command can be used to print the current protocol constants:

dune-client dune output protocol parameters

The Manage_accounts operation

The Manage_accounts operation is used to perform actions on accounts. The operation must be sent by a superadmin account.

The operation can contain the following fields:

• commitments: a list of pairs of a blinded key hash and an amount. The amount is taken from the account of the superadmin account. If a commitment already exists, the difference is debited or credited from the superadmin account;
• allow_peer_ids and revoke_peer_ids are two lists of peer identifiers used with On-Chain Access Control;
• fixes: a list of paths and corresponding bytes. These paths are used to perform corrections on the context;
• actions: a list of actions to perform, each action is associated with an amount of muduns, and a list of contracts.

The following actions are available:

• The unfreeze action can be used to unfreeze an account that has been frozen because it was not delegated;
• The undelegate action can be used to remove all the delegations of a list of bakers;
• The add_allowed_baker action can be used to add new allowed bakers;
• The remove_allowed_baker action can be used to remove allowed bakers;
• The add_superadmin action can be used to add new superadmins;
• The remove_superadmin action can be used to remove former superadmins;
• The kyc_accounts action can be used to change the KYC of accounts when the KYC level is not open;

Inject with dune_client

To inject the Manage_accounts operation, the following command can be used:

dune-client dune manage accounts with key SUPERADMIN and parameters JSONFILE
