Variables ¶

View Source

var ErrConsensusChange = errors.New("consensus program has changed")

ErrConsensusChange is returned from ValidateAndSignBlock when a new consensus program is detected.

View Source

var ErrInvalidKey = errors.New("misconfigured signer public key")

ErrInvalidKey is returned from SignBlock when the key specified on the Signer is invalid. It may be not found by the mock HSM or not paired to a valid private key.

Functions ¶

This section is empty.

Types ¶

type Signer ¶

type Signer struct {
	Pub ed25519.PublicKey
	// contains filtered or unexported fields
}

Signer validates and signs blocks.

func New ¶

func New(pub ed25519.PublicKey, hsm *mockhsm.HSM, db pg.DB, c *protocol.Chain) *Signer

New returns a new Signer that validates blocks with c and signs them with k.

func (*Signer) SignBlock ¶

func (s *Signer) SignBlock(ctx context.Context, b *bc.Block) ([]byte, error)

SignBlock computes the signature for the block using the private key in s. It does not validate the block.

func (*Signer) String ¶

func (s *Signer) String() string

func (*Signer) ValidateAndSignBlock ¶

func (s *Signer) ValidateAndSignBlock(ctx context.Context, b *bc.Block) ([]byte, error)

ValidateAndSignBlock validates the given block against the current blockchain and, if valid, computes and returns a signature for the block. It is used as the httpjson handler for /rpc/signer/sign-block.

This function fails if this node has ever signed a different block at the same height as b.
