Make Avalanche L1 Permissionless

Elastic Avalanche L1s are permissionless Avalanche L1s. More information can be found here.

This how-to guide focuses on taking an already created permissioned Avalanche L1 and transforming it to an elastic (or permissionless) Avalanche L1.

Prerequisites

• Avalanche-CLI installed
• You have deployed a permissioned Avalanche L1 on local, on Fuji or on Mainnet

Getting Started​

In the following commands, make sure to substitute the name of your Avalanche L1 configuration for <blockchainName>.

To transform your permissioned Avalanche L1 into an Elastic Avalanche L1 (NOTE: this action is irreversible), run:

avalanche blockchain elastic <blockchainName>

and, select the network that you want to transform the Avalanche L1 on. Alternatively, you can bypass this prompt by providing the --local, --fuji, or --mainnet flag.

Provide the name and the symbol for the permissionless Avalanche L1's native token. You can also bypass this prompt by providing the --tokenName and --tokenSymbol flags.

Next, select the Elastic Avalanche L1 config. You can choose to use the default values detailed here or customize the Elastic Avalanche L1 config. To bypass the prompt, you can use --default flag to use the default Elastic Avalanche L1 config.

The command may take a couple minutes to run.

Elastic Avalanche L1 Transformation on Fuji and Mainnet​

Elastic Avalanche L1 transformation on public network requires private key loaded into the tool, or a connected ledger device.

Both stored key usage and ledger usage are enabled on Fuji (see more on creating keys here) while only ledger usage is enabled on Mainnet (see more on setting up your ledger here).

To transform a permissioned Avalanche L1 into Elastic Avalanche L1 on public networks, users are required to provide the keys that control the Avalanche L1 defined during the Avalanche L1 deployment process (more info on keys in Fuji can be found here, while more info on ledger signing in Mainnet can be found here).

Results​

If all works as expected, you then have the option to automatically transform all existing permissioned validators to permissionless validators.

You can also to skip automatic transformation at this point and choose to manually add permissionless validators later.

You can use the output details such as the Asset ID and Elastic Avalanche L1 ID (SubnetID) to connect to and interact with your Elastic Avalanche L1.

Adding Permissionless Validators to Elastic Avalanche L1​

If you are running this command on local network, you will need to first remove permissioned validators (by running avalanche subnet removeValidator <blockchainName>) so that you can have a list of local nodes to choose from to be added as a permissionless validator in the Elastic Avalanche L1.

To add permissionless validators to an Elastic Avalanche L1, run:

avalanche blockchain join <blockchainName> --elastic

You will be prompted with which node you would like to add as a permissionless validator. You can skip this prompt by using --nodeID flag.

You will then be prompted with the amount of the Avalanche L1 native token that you like to stake in the validator. Alternatively, you can bypass this prompt by providing the --stake-amount flag. Note that choosing to add the maximum validator stake amount (defined during Elastic Avalanche L1 transformation step above) means that you effectively disable delegation in your validator.

Next, select when the validator will start validating and how long it will be validating for. You can also bypass these prompts by using --start-time and --staking-period flags.

Adding Permissionless Delegator to a Permissionless Validator in Elastic Avalanche L1​

To add permissionless delegators, run:

avalanche blockchain addPermissionlessDelegator <blockchainName>

You will be prompted with which Avalanche L1 validator you would like to delegate to. You can skip this prompt by using --nodeID flag.

You will then be prompted with the amount of the Avalanche L1 native token that you like to stake in the validator. Alternatively, you can bypass this prompt by providing the --stake-amount flag. The amount that can be delegated to a validator is detailed here.

Next, select when you want to start delegating and how long you want to delegate for. You can also bypass these prompts by using --start-time and --staking-period flags.
