Example 1 with InclusionInfo

use of tech.pegasys.teku.spec.logic.common.statetransition.epoch.status.InclusionInfo in project teku by ConsenSys.

the class ValidatorStatusFactoryPhase0 method processParticipation.

@Override

    final BeaconStatePhase0 state = BeaconStatePhase0.required(genericState);
    Stream.concat(state.getPrevious_epoch_attestations().stream(), state.getCurrent_epoch_attestations().stream()).forEach(attestation -> {
        final AttestationData data = attestation.getData();

                updates.previousEpochHeadAttester = beaconStateAccessors.getBlockRootAtSlot(state, data.getSlot()).equals(data.getBeacon_block_root());
            }
        }
        // Apply flags to attestingIndices
        attestationUtil.streamAttestingIndices(state, data, attestation.getAggregation_bits()).mapToObj(statuses::get).forEach(updates::apply);
    });

Example 2 with InclusionInfo

use of tech.pegasys.teku.spec.logic.common.statetransition.epoch.status.InclusionInfo in project teku by ConsenSys.

the class RewardsAndPenaltiesCalculatorPhase0 method applyInclusionDelayDelta.

public void applyInclusionDelayDelta(final ValidatorStatus validator, final UInt64 baseReward, final RewardAndPenalty delta, final RewardAndPenaltyDeltas deltas) {
    if (validator.isPreviousEpochSourceAttester() && !validator.isSlashed()) {
        final InclusionInfo inclusionInfo = validator.getInclusionInfo().orElseThrow(() -> new IllegalStateException("Validator was active in previous epoch but has no inclusion information."));
        final UInt64 proposerReward = getProposerReward(baseReward);
