This document provides details about the configuration options available for the PlatformVM.

In order to specify a configuration for the PlatformVM, you need to define a Config struct and its parameters. The default values for these parameters are:

{
  "Chains": null,
  "Validators": null,
  "UptimeLockedCalculator": null,
  "SybilProtectionEnabled": false,
  "PartialSyncPrimaryNetwork": false,
  "TrackedSubnets": [],
  "TxFee": 0,
  "CreateAssetTxFee": 0,
  "CreateSubnetTxFee": 0,
  "TransformSubnetTxFee": 0,
  "CreateBlockchainTxFee": 0,
  "AddPrimaryNetworkValidatorFee": 0,
  "AddPrimaryNetworkDelegatorFee": 0,
  "AddSubnetValidatorFee": 0,
  "AddSubnetDelegatorFee": 0,
  "MinValidatorStake": 0,
  "MaxValidatorStake": 0,
  "MinDelegatorStake": 0,
  "MinDelegationFee": 0,
  "UptimePercentage": 0,
  "MinStakeDuration": "0s",
  "MaxStakeDuration": "0s",
  "RewardConfig": {},
  "ApricotPhase3Time": "0001-01-01T00:00:00Z",
  "ApricotPhase5Time": "0001-01-01T00:00:00Z",
  "BanffTime": "0001-01-01T00:00:00Z",
  "CortinaTime": "0001-01-01T00:00:00Z",
  "DurangoTime": "0001-01-01T00:00:00Z",
  "EUpgradeTime": "0001-01-01T00:00:00Z",
  "UseCurrentHeight": false
}

Default values are overridden only if explicitly specified in the config.

Parameters​

The parameters are as follows:

Chains​

The node's chain manager

Validators​

Node's validator set maps SubnetID to validators of the Subnet

  • The primary network's validator set should have been added to the manager before calling VM.Initialize.
  • The primary network's validator set should be empty before calling VM.Initialize.

UptimeLockedCalculator​

Provides access to the uptime manager as a thread-safe data structure

SybilProtectionEnabled​

Boolean

True if the node is being run with staking enabled

PartialSyncPrimaryNetwork​

Boolean

If true, only the P-chain will be instantiated on the primary network.

TrackedSubnets​

Set of Subnets that this node is validating

TxFee​

Uint64

Fee that is burned by every non-state creating transaction

CreateAssetTxFee​

Uint64

Fee that must be burned by every state creating transaction before AP3

CreateSubnetTxFee​

Uint64

Fee that must be burned by every Subnet creating transaction after AP3

TransformSubnetTxFee​

Uint64

Fee that must be burned by every transform Subnet transaction

CreateBlockchainTxFee​

Uint64

Fee that must be burned by every blockchain creating transaction after AP3

AddPrimaryNetworkValidatorFee​

Uint64

Transaction fee for adding a primary network validator

AddPrimaryNetworkDelegatorFee​

Uint64

Transaction fee for adding a primary network delegator

AddSubnetValidatorFee​

Uint64

Transaction fee for adding a Subnet validator

AddSubnetDelegatorFee​

Uint64

Transaction fee for adding a Subnet delegator

MinValidatorStake​

Uint64

The minimum amount of tokens one must bond to be a validator

MaxValidatorStake​

Uint64

The maximum amount of tokens that can be bonded on a validator

MinDelegatorStake​

Uint64

Minimum stake, in nAVAX, that can be delegated on the primary network

MinDelegationFee​

Uint32

Minimum fee that can be charged for delegation

UptimePercentage​

Float64

UptimePercentage is the minimum uptime required to be rewarded for staking

MinStakeDuration​

Duration

Minimum amount of time to allow a staker to stake

MaxStakeDuration​

Duration

Maximum amount of time to allow a staker to stake

RewardConfig​

Config for the minting function

ApricotPhase3Time​

Time

Time of the AP3 network upgrade

ApricotPhase5Time​

Time

Time of the AP5 network upgrade

BanffTime​

Time

Time of the Banff network upgrade

CortinaTime​

Time

Time of the Cortina network upgrade

DurangoTime​

Time

Time of the Durango network upgrade

EUpgradeTime​

Time

Time of the E network upgrade

UseCurrentHeight​

Boolean

UseCurrentHeight forces GetMinimumHeight to return the current height of the P-Chain instead of the oldest block in the recentlyAccepted window. This config is particularly useful for triggering proposervm activation on recently created Subnets (without this, users need to wait for recentlyAcceptedWindowTTL to pass for activation to occur).
