Types

type LightRoot

type LightRoot struct {
	TrustHeight int64  `json:"trust-height"`
	TrustHash   string `json:"trust-hash"`
}

LightRoot is the format for a light client root file which will be used for state sync

type Peer

type Peer struct {
	ID                string    `json:"id,omitempty"`
	Address           string    `json:"address,omitempty"`
	IsSeed            bool      `json:"is_seed,omitempty"`
	LastContactHeight int64     `json:"last_contact_height,omitempty"`
	LastContactDate   time.Time `json:"last_contact_date,omitempty"`
	UpdatedAt         time.Time `json:"updated_at,omitempty"`
	Reachable         bool      `json:"reachable,omitempty"`
}

Peer structure to keep track of the status of a peer
