eth2.0-specs/specs/validator/beacon_node_oapi.yaml
Luke Anderson 48ed25b2bd
Fleshed out a lot more of the API, nearly ready.
- Added all the fields from BeaconBlock(Body)
 - Tagged all paths as 'Minimum for validator'
 - Removed BeaconNode and ValidatorClient conventions
 - Moved the basic non-object schema components to the top
 - Broke out common beacon block properties into the BeaconBlockCommon object
 - Fixed links to Eth2.0 spec
