Functions

func IsSurround

func IsSurround(a, b *ethpb.IndexedAttestation) bool

IsSurround checks if an attestation, a, is surrounding another one, b, based on the Ethereum slashing conditions specified by @protolambda https://github.com/protolambda/eth2-surround#definition.

s: source
t: target

a surrounds b if: s_a < s_b and t_b < t_a

func SigningRootsDiffer

func SigningRootsDiffer(existingSigningRoot, incomingSigningRoot [32]byte) bool

SigningRootsDiffer verifies that an incoming vs. existing attestation has a different signing root. If the existing signing root is empty, then we consider an attestation as different always.
