Closed djrtwo closed 6 years ago

djrtwo commented 6 years ago

Issue

v2.1 spec now has new fields (justified_slot and justified_block_hash) in Attestation and some logic regarding these fields when processing attestations.

Proposed Implementation

add justified_slot and justified_block_hash to Attestation
When validating attestation,

Verify that the justified_slot and justified_block_hash given are in the chain and are equal to or earlier than the last_justified_slot in the crystallized state.
