PlatformVM

Mempool Gossiping

The PlatformVM has a mempool which tracks unconfirmed transactions that are waiting to be issued into blocks. The mempool is volatile, i.e. it does not persist unconfirmed transactions.

In conjunction with the introduction of Snowman++, the mempool was opened to the network, allowing the gossiping of local transactions as well as the hosting of remote ones.

Mempool Gossiping Workflow

The PlatformVM's mempool performs the following workflow:

  • An unconfirmed transaction is provided to node A, either through mempool gossiping or direct issuance over a RPC. If this transaction isn't already in the local mempool, the transaction is issued into the mempool.
  • When node A issues a new transaction into its mempool, it will gossip the transaction ID by sending an AppGossip message. The node's engine will randomly select peers (currently defaulting to 6 nodes) to send the AppGossip message to.
  • When node B learns about the existence of a remote transaction ID, it will check if its mempool contains the transaction or if it has been recently dropped. If the transaction ID is not known, node B will generate a new requestID and respond with an AppRequest message with the unknown transaction's ID. node B will track the content of the request issued with requestID for response verification.
  • Upon reception of an AppRequest message, node A will attempt to fetch the transaction requested in the AppRequest message from its mempool. Note that a transaction advertised in an AppGossip message may no longer be in the mempool, because they may have been included into a block, rejected, or dropped. If the transaction is retrieved, it is encoded into an AppResponse message. The AppResponse message will carry the same requestID of the originating AppRequest message and it will be sent back to node B.
  • If node B receives an AppResponse message, it will decode the transaction and verifies that the ID matches the expected content from the original AppRequest message. If the content matches, the transaction is validated and issued into the mempool.
  • If nodeB's engine decides it isn't likely to receive an AppResponse message, the engine will issue an AppRequestFailure message. In such a case node B will mark the requestID as failed and the request for the unknown transaction is aborted.

Functions

func CanDelegate

func CanDelegate(
	current,
	pending []*UnsignedAddDelegatorTx,
	new *UnsignedAddDelegatorTx,
	currentStake,
	maximumStake uint64,
) (bool, error)

CanDelegate returns if the [new] delegator can be added to a validator who has [current] and [pending] delegators. [currentStake] is the current amount of stake on the validator, include the [current] delegators. [maximumStake] is the maximum amount of stake that can be on the validator at any given time. It is assumed that the validator without adding [new] does not violate [maximumStake].

UnsignedProposalTx is an unsigned operation that can be proposed

type UnsignedRewardValidatorTx

type UnsignedRewardValidatorTx struct {
	avax.Metadata

	// ID of the tx that created the delegator/validator being removed/rewarded
	TxID ids.ID `serialize:"true" json:"txID"`
	// contains filtered or unexported fields
}

UnsignedRewardValidatorTx is a transaction that represents a proposal to remove a validator that is currently validating from the validator set.

If this transaction is accepted and the next block accepted is a Commit block, the validator is removed and the address that the validator specified receives the staked AVAX as well as a validating reward.

If this transaction is accepted and the next block accepted is an Abort block, the validator is removed and the address that the validator specified receives the staked AVAX but no reward.

func (*UnsignedRewardValidatorTx) Execute

func (tx *UnsignedRewardValidatorTx) Execute(
	vm *VM,
	parentState MutableState,
	stx *Tx,
) (
	VersionedState,
	VersionedState,
	error,
)

Execute this transaction.

The current validating set must have at least one member. The next validator to be removed must be the validator specified in this block. The next validator to be removed must be have an end time equal to the current

chain timestamp.

func (tx *UnsignedRewardValidatorTx) InitCtx(*snow.Context)

func (*UnsignedRewardValidatorTx) InitiallyPrefersCommit

func (tx *UnsignedRewardValidatorTx) InitiallyPrefersCommit(*VM) bool

InitiallyPrefersCommit returns true if this node thinks the validator should receive a staking reward.

TODO: A validator should receive a reward only if they are sufficiently responsive and correct during the time they are validating. Right now they receive a reward if they're up (but not necessarily correct and responsive) for a sufficient amount of time

GetCurrentHeight returns the height of the last accepted block

func (*VM) GetMinimumHeight added in v1.7.16

func (vm *VM) GetMinimumHeight() (uint64, error)

GetMinimumHeight returns the height of the most recent block beyond the horizon of our recentlyAccepted window.

Because the time between blocks is arbitrary, we're only guaranteed that the window's configured TTL amount of time has passed once an element expires from the window.

To try to always return a block older than the window's TTL, we return the parent of the oldest element in the window (as an expired element is always guaranteed to be sufficiently stale). If we haven't expired an element yet in the case of a process restart, we default to the lastAccepted block's height which is likely (but not guaranteed) to also be older than the window's configured TTL.
