Variables ¶
var ErrInvalidRoot = errors.New("invalid identity root")
ErrInvalidRoot shows that identity root verification flow completed without internal errors, but the root itself is invalid
Functions ¶

Types ¶
type DisabledVerifier ¶
type DisabledVerifier struct{}
DisabledVerifier returns nil error on verification
func (DisabledVerifier) VerifyRoot ¶
func (v DisabledVerifier) VerifyRoot(_ string) error
type PoseidonSMTVerifier ¶
type PoseidonSMTVerifier struct {
// contains filtered or unexported fields
}
PoseidonSMTVerifier is a wrapper around PoseidonSMT binding which calls IsRootValid on the contract. Currently used for GlobalPassport and GeorgianPassport proof types.
func NewPoseidonSMTVerifier ¶
func NewPoseidonSMTVerifier(rpcURL, contract string, timeout time.Duration) (*PoseidonSMTVerifier, error)
func (*PoseidonSMTVerifier) VerifyRoot ¶
func (v *PoseidonSMTVerifier) VerifyRoot(root string) error
type ProposalSMTVerifier ¶
type ProposalSMTVerifier struct {
// contains filtered or unexported fields
}
ProposalSMTVerifier performs validation with filtering RootUpdated events of ProposalSMT contract by root value. Currently used for PollParticipation proof type.
func NewProposalSMTVerifier ¶
func NewProposalSMTVerifier(rpcURL string, timeout time.Duration) *ProposalSMTVerifier
NewProposalSMTVerifier creates basic ProposalSMTVerifier with RPC only. You must call WithContract to use it.
func (*ProposalSMTVerifier) VerifyRoot ¶
func (v *ProposalSMTVerifier) VerifyRoot(root string) error
func (*ProposalSMTVerifier) WithContract ¶
func (v *ProposalSMTVerifier) WithContract(addr string) Verifier
WithContract returns new instance of ProposalSMTVerifier which will call the provided contract. Provided address must be a valid 20-byte hex.
type Verifier ¶
Verifier is an abstraction to verify the root value against some state. Root must be provided as decimal string, acquired from ZK-proof public signals, which is then converted tot 32-byte array.
type VerifierProvider ¶
type VerifierProvider interface {
ProvideVerifier() Verifier
}
VerifierProvider provides a Verifier based on the given VerifierType from config map.
Specifying "disabled: true" in config allows to skip other map fields.
func NewVerifierProvider ¶
func NewVerifierProvider(getter kv.Getter, typ VerifierType) VerifierProvider
NewVerifierProvider creates a new provider with given VerifierType. You must specify the name equal to VerifierType in map: this allows to have multiple verifiers in the same app. For custom name or logic write your own config map handler.
type VerifierType ¶
type VerifierType string
const ( PoseidonSMT VerifierType = "poseidonsmt_root_verifier" ProposalSMT = "proposalsmt_root_verifier" )
