## Modifications in EIP-7549
|
|
|
|
### Block proposal
|
|
|
|
#### Constructing the `BeaconBlockBody`
|
|
|
|
##### Attestations
|
|
|
|
Attestations received from aggregators with disjoint `committee_bits` sets and equal `AttestationData` SHOULD be consolidated into a single `Attestation` object.
|
|
|
|
### Attesting
|
|
|
|
#### Construct attestation
|
|
|
|
- Set `attestation_data.index = 0`.
|
|
- Let `aggregation_bits` be a `Bitlist[MAX_VALIDATORS_PER_COMMITTEE]` of length `len(committee)`, where the bit of the index of the validator in the `committee` is set to `0b1`.
|
|
- Set `attestation.aggregation_bits = [aggregation_bits]`, a list of length 1
|
|
- Let `committee_bits` be a `Bitvector[MAX_COMMITTEES_PER_SLOT]`, where the bit at the index associated with the validator's committee is set to `0b1`
|
|
- Set `attestation.committee_bits = committee_bits`
|
|
|
|
*Note*: Calling `get_attesting_indices(state, attestation)` should return a list of length equal to 1, containing `validator_index`.
|
|
|
|
### Attestation aggregation
|
|
|
|
#### Construct aggregate
|
|
|
|
- Set `attestation_data.index = 0`.
|
|
- Let `aggregation_bits` be a `Bitlist[MAX_VALIDATORS_PER_COMMITTEE]` of length `len(committee)`, where each bit set from each individual attestation is set to `0b1`.
|
|
- Set `attestation.aggregation_bits = [aggregation_bits]`, a list of length 1
|
|
- Set `attestation.committee_bits = committee_bits`, where `committee_bits` has the same value as in each individual attestation
