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"`
	LastSignBytes cmn.HexBytes   `json:"last_signbytes,omitempty"`
	PrivKey       crypto.PrivKey `json:"priv_key"`
	// contains filtered or unexported fields
}

FilePV implements PrivValidator using data persisted to disk to prevent double signing. NOTE: the directory containing the pv.filePath must already exist. It includes the LastSignature and LastSignBytes so we don't lose the signature if the process crashes after signing but before the resulting consensus message is processed.

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 RemoteSignerError 

type RemoteSignerError struct {
	// TODO(ismail): create an enum of known errors
	Code        int
	Description string
}

RemoteSignerError allows (remote) validators to include meaningful error descriptions in their reply.

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 SignHeartbeatRequest 

type SignHeartbeatRequest struct {
	Heartbeat *types.Heartbeat
}

SignHeartbeatRequest is a PrivValidatorSocket message containing a Heartbeat.

type SignProposalRequest 

type SignProposalRequest struct {
	Proposal *types.Proposal
}

SignProposalRequest is a PrivValidatorSocket message containing a Proposal.

type SignVoteRequest 

type SignVoteRequest struct {
	Vote *types.Vote
}

type SignedHeartbeatResponse 

type SignedHeartbeatResponse struct {
	Heartbeat *types.Heartbeat
	Error     *RemoteSignerError
}

type SignedProposalResponse 

type SignedProposalResponse struct {
	Proposal *types.Proposal
	Error    *RemoteSignerError
}

type SignedVoteResponse

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.
