Types

type FileStateMgr

type FileStateMgr struct {
	// contains filtered or unexported fields
}

FileStateMgr save the local state to file

func NewFileStateMgr

func NewFileStateMgr(folder string) (*FileStateMgr, error)

NewFileStateMgr create a new instance of the FileStateMgr which implements LocalStateManager

func (*FileStateMgr) GetLocalState

func (fsm *FileStateMgr) GetLocalState(pubAddr string) (*KeygenLocalState, error)

GetLocalState read the local state from file system

func (*FileStateMgr) SaveLocalState

func (fsm *FileStateMgr) SaveLocalState(state *KeygenLocalState) error

SaveLocalState save the local state to file

type KeygenLocalState

type KeygenLocalState struct {
	// TSS pool pubkey raw byte
	PubKeyData []byte `json:"pub_key_data"`
	// TSS pool pubkey addr
	PubKeyAddr string `json:"pub_key_addr"`
	// the library method returns information that needs to be stored at the end of the keyGen
	LocalData keygen.LocalPartySaveData `json:"local_data"`

	// partyID.id -> pubkey
	ParticipantPksMap map[string][]byte `json:"participant_pks_map"` // the paticipant of last key gen
	LocalPartyPk      []byte            `json:"local_party_pk"`
}

KeygenLocalState is a structure used to represent the data we saved locally for different keygen A TSS public key address stores a corresponding KeygenLocalState structure

type LocalStateManager

type LocalStateManager interface {
	SaveLocalState(state *KeygenLocalState) error
	GetLocalState(pubAddr string) (*KeygenLocalState, error)
}

LocalStateManager provide necessary methods to manage the local state, save it , and read it back LocalStateManager doesn't have any opinion in regards to where it should be persistent to
