Types

type PublicParamsLoader

type PublicParamsLoader interface {
	// Fetch fetches the public parameters from the backend
	Fetch() ([]byte, error)
	// FetchParams fetches the public parameters from the backend and unmarshal them.
	// The public parameters are also validated.
	FetchParams() (*fabtoken.PublicParams, error)
}

type PublicParamsManager

type PublicParamsManager struct {
	// fabtoken public parameters
	PP *fabtoken.PublicParams
	// a loader for fabric public parameters
	PublicParamsLoader PublicParamsLoader
	// the vault
	Vault Vault
	// label of the public params
	PPLabel string

	Mutex sync.RWMutex
}
