Types ¶
type Node ¶
type Node struct {
// contains filtered or unexported fields
}
Node holds interfaces to interact with the blockchain and network messages transport layer.
func NewNode ¶
func NewNode( ethereumChain eth.Handle, networkProvider net.Provider, tssConfig *tss.Config, ) *Node
NewNode initializes node struct with provided ethereum chain interface and network provider. It also initializes TSS Pre-Parameters pool. But does not start parameters generation. This should be called separately.
func (*Node) AnnounceSignerPresence ¶
func (n *Node) AnnounceSignerPresence( ctx context.Context, operatorPublicKey *operator.PublicKey, keepAddress common.Address, keepMembersAddresses []common.Address, ) ([]tss.MemberID, error)
AnnounceSignerPresence triggers the announce protocol in order to signal signer presence and gather information about other signers.
func (*Node) CalculateSignature ¶
func (n *Node) CalculateSignature( ctx context.Context, signer *tss.ThresholdSigner, digest [32]byte, ) error
CalculateSignature calculates a signature over a digest with threshold signer and publishes the result to the keep associated with the signer. In case of failure on signature submission we need to check if the keep is still waiting for the signature. It is possible that other member was faster than the current one and submitted the signature first.
func (*Node) GenerateSignerForKeep ¶
func (n *Node) GenerateSignerForKeep( ctx context.Context, operatorPublicKey *operator.PublicKey, keepAddress common.Address, keepMembersIDs []tss.MemberID, ) (*tss.ThresholdSigner, error)
GenerateSignerForKeep generates a new threshold signer with ECDSA key pair. The public key is a public key of the signing group. It publishes the public key to the keep. It uses keep address as unique signing group identifier.
func (*Node) InitializeTSSPreParamsPool ¶
func (n *Node) InitializeTSSPreParamsPool()
InitializeTSSPreParamsPool generates TSS pre-parameters and stores them in a pool.
