Types

type FilePV

type FilePV struct {
	Address       types.Address  `json:"address"`
	PubKey        crypto.PubKey  `json:"pub_key"`
	LastHeight    int64          `json:"last_height"`
	LastRound     int            `json:"last_round"`
	LastStep      int8           `json:"last_step"`
	LastSignature []byte         `json:"last_signature,omitempty"` // so we dont lose signatures XXX Why would we lose signatures?
	LastSignBytes cmn.HexBytes   `json:"last_signbytes,omitempty"` // so we dont lose signatures XXX Why would we lose signatures?
	PrivKey       crypto.PrivKey `json:"priv_key"`

}

FilePV implements PrivValidator using data persisted to disk to prevent double signing. NOTE: the directory containing the pv.filePath must already exist.

func GenFilePV

func GenFilePV(filePath string) *FilePV

GenFilePV generates a new validator with randomly generated private key and sets the filePath, but does not call Save().

func LoadFilePV

func LoadFilePV(filePath string) *FilePV

LoadFilePV loads a FilePV from the filePath. The FilePV handles double signing prevention by persisting data to the filePath. If the filePath does not exist, the FilePV must be created manually and saved.

func LoadOrGenFilePV

func LoadOrGenFilePV(filePath string) *FilePV

LoadOrGenFilePV loads a FilePV from the given filePath or else generates a new one and saves it to the filePath.

func (*FilePV) GetAddress

func (pv *FilePV) GetAddress() types.Address

GetAddress returns the address of the validator. Implements PrivValidator.

func (*FilePV) GetPubKey

func (pv *FilePV) GetPubKey() crypto.PubKey

GetPubKey returns the public key of the validator. Implements PrivValidator.

func (*FilePV) Reset

func (pv *FilePV) Reset()

Reset resets all fields in the FilePV. NOTE: Unsafe!

func (*FilePV) Save

func (pv *FilePV) Save()

Save persists the FilePV to disk.

func (*FilePV) SignHeartbeat

func (pv *FilePV) SignHeartbeat(chainID string, heartbeat *types.Heartbeat) error

SignHeartbeat signs a canonical representation of the heartbeat, along with the chainID. Implements PrivValidator.

func (*FilePV) SignProposal

func (pv *FilePV) SignProposal(chainID string, proposal *types.Proposal) error

SignProposal signs a canonical representation of the proposal, along with the chainID. Implements PrivValidator.

func (*FilePV) SignVote

func (pv *FilePV) SignVote(chainID string, vote *types.Vote) error

SignVote signs a canonical representation of the vote, along with the chainID. Implements PrivValidator.

func (*FilePV) String

func (pv *FilePV) String() string

String returns a string representation of the FilePV.

type PubKeyMsg

type PubKeyMsg struct {
	PubKey crypto.PubKey
}

PubKeyMsg is a PrivValidatorSocket message containing the public key.

type RemoteSigner

type RemoteSigner struct {
	cmn.BaseService
	// contains filtered or unexported fields
}

RemoteSigner implements PrivValidator by dialing to a socket.

func NewRemoteSigner

func NewRemoteSigner(
	logger log.Logger,
	chainID, socketAddr string,
	privVal types.PrivValidator,
	privKey ed25519.PrivKeyEd25519,
) *RemoteSigner

NewRemoteSigner returns an instance of RemoteSigner.

func (*RemoteSigner) OnStart

func (rs *RemoteSigner) OnStart() error

OnStart implements cmn.Service.

func (*RemoteSigner) OnStop

func (rs *RemoteSigner) OnStop()

OnStop implements cmn.Service.

type RemoteSignerOption

type RemoteSignerOption func(*RemoteSigner)

RemoteSignerOption sets an optional parameter on the RemoteSigner.

func RemoteSignerConnDeadline

func RemoteSignerConnDeadline(deadline time.Duration) RemoteSignerOption

RemoteSignerConnDeadline sets the read and write deadline for connections from external signing processes.

func RemoteSignerConnRetries

func RemoteSignerConnRetries(retries int) RemoteSignerOption

RemoteSignerConnRetries sets the amount of attempted retries to connect.

type SignHeartbeatMsg

type SignHeartbeatMsg struct {
	Heartbeat *types.Heartbeat
}

SignHeartbeatMsg is a PrivValidatorSocket message containing a Heartbeat.

type SignProposalMsg

type SignProposalMsg struct {
	Proposal *types.Proposal
}

SignProposalMsg is a PrivValidatorSocket message containing a Proposal.

type SignVoteMsg

type SignVoteMsg struct {
	Vote *types.Vote
}

SignVoteMsg is a PrivValidatorSocket message containing a vote.

type SocketPV

type SocketPV struct {
	cmn.BaseService
	// contains filtered or unexported fields
}

SocketPV implements PrivValidator, it uses a socket to request signatures from an external process.

func NewSocketPV

func NewSocketPV(
	logger log.Logger,
	socketAddr string,
	privKey ed25519.PrivKeyEd25519,
) *SocketPV

NewSocketPV returns an instance of SocketPV.
