Variables

var Curve = secp256k1.S256()

Curve is the elliptic Curve on which on-chain messages are to be signed

Functions

func VerifyOnChain

func VerifyOnChain(msg []byte, signature []byte, signers EthAddresses,
) (commontypes.OracleID, error)

VerifyOnChain returns an error unless signature is a valid signature by one of the signers, in which case it returns the ID of the signer

Types

type EthAddresses

type EthAddresses = map[types.OnChainSigningAddress]commontypes.OracleID

type OffchainPrivateKey

type OffchainPrivateKey ed25519.PrivateKey

OffchainPrivateKey is the secret key oracles use to sign messages destined for off-chain verification by other oracles

func (*OffchainPrivateKey) PublicKey

func (k *OffchainPrivateKey) PublicKey() OffchainPublicKey

PublicKey returns the public key which commits to k

func (*OffchainPrivateKey) Sign

func (k *OffchainPrivateKey) Sign(msg []byte) ([]byte, error)

Sign returns the signature on msgHash with k

type OffchainPublicKey

type OffchainPublicKey ed25519.PublicKey

OffchainPublicKey is the public key used to cryptographically identify an oracle in inter-oracle communications.

func (OffchainPublicKey) Equal

func (k OffchainPublicKey) Equal(k2 OffchainPublicKey) bool

Equal returns true iff k and k2 represent the same public key

func (OffchainPublicKey) Verify

func (k OffchainPublicKey) Verify(msg, signature []byte) bool

Verify returns true iff signature is a valid signature by k on msg

type OnChainPublicKey

type OnChainPublicKey ecdsa.PublicKey

OnChainPublicKey is the public key used to cryptographically identify an oracle to the on-chain smart contract.

func (OnChainPublicKey) Address

func (k OnChainPublicKey) Address() types.OnChainSigningAddress

func (OnChainPublicKey) Equal

func (k OnChainPublicKey) Equal(k2 OnChainPublicKey) bool

Equal returns true iff k and k2 represent the same public key

type OnchainPrivateKey

type OnchainPrivateKey ecdsa.PrivateKey

OnchainPrivateKey is the secret key oracles use to sign messages destined for verification by the on-chain smart contract.

func (OnchainPrivateKey) Address

func (k OnchainPrivateKey) Address() types.OnChainSigningAddress

func (*OnchainPrivateKey) Sign

func (k *OnchainPrivateKey) Sign(msg []byte) (signature []byte, err error)

Sign signs message with k
