Types

type Block

type Block struct {
	// Height contains the block height.
	Height int64 `json:"height"`
	// Hash contains the block header hash.
	Hash []byte `json:"hash"`
	// Time is the second-granular consensus time.
	Time time.Time `json:"time"`
	// StateRoot is the Merkle root of the consensus state tree.
	StateRoot mkvsNode.Root `json:"state_root"`
	// Meta contains the consensus backend specific block metadata.
	Meta cbor.RawMessage `json:"meta"`
}

Block is a consensus block.

While some common fields are provided, most of the structure is dependent on the actual backend implementation.

type EstimateGasRequest

type EstimateGasRequest struct {
	Signer      signature.PublicKey      `json:"signer"`
	Transaction *transaction.Transaction `json:"transaction"`
}

EstimateGasRequest is a EstimateGas request.

type Evidence

type Evidence struct {
	// Meta contains the consensus backend specific evidence.
	Meta []byte `json:"meta"`
}

Evidence is evidence of a node's Byzantine behavior.

type FeatureMask

type FeatureMask uint8

FeatureMask is the consensus backend feature bitmask.

const (
	// FeatureServices indicates support for communicating with consensus services.
	FeatureServices FeatureMask = 1 << 0

	// FeatureFullNode indicates that the consensus backend is independently fully verifying all
	// consensus-layer blocks.
	FeatureFullNode FeatureMask = 1 << 1
)

func (FeatureMask) String

func (m FeatureMask) String() string

String returns a string representation of the consensus backend feature bitmask.

type GetSignerNonceRequest

type GetSignerNonceRequest struct {
	AccountAddress staking.Address `json:"account_address"`
	Height         int64           `json:"height"`
}

GetSignerNonceRequest is a GetSignerNonce request.

type HaltHook

type HaltHook func(ctx context.Context, blockHeight int64, epoch beacon.EpochTime, err error)

HaltHook is a function that gets called when consensus needs to halt for some reason.

type LightBlock

type LightBlock struct {
	// Height contains the block height.
	Height int64 `json:"height"`
	// Meta contains the consensus backend specific light block.
	Meta []byte `json:"meta"`
}

LightBlock is a light consensus block suitable for syncing light clients.

type Parameters

type Parameters struct {
	// Height contains the block height these consensus parameters are for.
	Height int64 `json:"height"`
	// Parameters are the backend agnostic consensus parameters.
	Parameters genesis.Parameters `json:"parameters"`
	// Meta contains the consensus backend specific consensus parameters.
	Meta []byte `json:"meta"`
}

Parameters are the consensus backend parameters.

type Status

type Status struct {
	// Version is the version of the consensus protocol that the node is using.
	Version version.Version `json:"version"`
	// Backend is the consensus backend identifier.
	Backend string `json:"backend"`
	// Features are the indicated consensus backend features.
	Features FeatureMask `json:"features"`

	// NodePeers is a list of node's peers.
	NodePeers []string `json:"node_peers"`

	// LatestHeight is the height of the latest block.
	LatestHeight int64 `json:"latest_height"`
	// LatestHash is the hash of the latest block.
	LatestHash []byte `json:"latest_hash"`
	// LatestTime is the timestamp of the latest block.
	LatestTime time.Time `json:"latest_time"`
	// LatestEpoch is the epoch of the latest block.
	LatestEpoch beacon.EpochTime `json:"latest_epoch"`
	// LatestStateRoot is the Merkle root of the consensus state tree.
	LatestStateRoot mkvsNode.Root `json:"latest_state_root"`

	// GenesisHeight is the height of the genesis block.
	GenesisHeight int64 `json:"genesis_height"`
	// GenesisHash is the hash of the genesis block.
	GenesisHash []byte `json:"genesis_hash"`

	// LastRetainedHeight is the height of the oldest retained block.
	LastRetainedHeight int64 `json:"last_retained_height"`
	// LastRetainedHash is the hash of the oldest retained block.
	LastRetainedHash []byte `json:"last_retained_hash"`

	// ChainContext is the chain domain separation context.
	ChainContext string `json:"chain_context"`

	// IsValidator returns whether the current node is part of the validator set.
	IsValidator bool `json:"is_validator"`
}

Status is the current status overview.

type TransactionsWithResults

type TransactionsWithResults struct {
	Transactions [][]byte          `json:"transactions"`
	Results      []*results.Result `json:"results"`
}

TransactionsWithResults is GetTransactionsWithResults response.

Results[i] are the results of executing Transactions[i].
