const EXPIRED_IN = time.Hour * 24 * 3

EXPIRED_IN is the time after which a proof is considered expired and should perform revalidate.

Variables

var (
	DB *gorm.DB
	// Since this service is mostly run as a lambda, we don't need
	// to init an array here.  When lambda scaled to a very large

)

Functions

func Init 

func Init()

Init initializes DB connection instance and do migration at startup.

func MarshalPersona 

func MarshalPersona(persona any) string

MarshalPersona accepts *ecdsa.Pubkey | string type of pubkey, returns a string to be stored into DB.

func MarshalSignature 

func MarshalSignature(signature []byte) string

MarshalSignature converts []byte signature into string.

Types

type Proof 

type Proof struct {
	ID            int64 `gorm:"primarykey"`
	CreatedAt     time.Time
	LastCheckedAt time.Time
	IsValid       bool
	InvalidReason string

	ProofChainID int64 `gorm:"index"`
	ProofChain   ProofChain
	// Persona is public key of user persona (string, /0x[0-9a-f]{130}/)
	Persona  string         `gorm:"index;not null"`
	Platform types.Platform `gorm:"index;not null"`
	Identity string         `gorm:"index;not null"`
