The beacon.raw.balances_daily table provides daily snapshots of validator balances on the Beacon Chain. Each row is one validator’s state for a given day: the snapshot is taken at the last slot of the calendar day in UTC (for example 2026-03-28 23:59:59.000 on slot_timestamp).

​
Use Cases

Daily accounting and reconciliation: Build per-validator daily balances and roll up to network-level metrics. Performance tracking: Compare balance or raw_balance across consecutive days for income, slashing, and withdrawal-related changes. Network health analysis: Aggregate by day to study total staked ETH, validator counts by status, and participation over time.

Table Columns

Clustering Key: slot_timestamp (daily snapshot boundary) Search Optimization: validator_index Unique Key: unique_id
Column NameDescription
slot_numberBeacon Chain slot number for the end-of-day snapshot.
slot_timestampTimestamp of that slot (UTC), typically 23:59:59 on the snapshot calendar day.
validator_indexIndex of the validator in the Beacon validator registry.
raw_balanceValidator balance as an integer in gwei (1e9 gwei = 1 ETH).
balanceValidator balance in ETH (float).
effective_balanceEffective balance at stake in ETH (used for reward and penalty calculations).
raw_effective_balanceEffective balance at stake in gwei.
statusValidator status (for example active_ongoing, withdrawal_done, exited_unslashed, exited_slashed, pending_queued, pending_initialized).
pubkeyValidator BLS public key (48 bytes, hex with 0x prefix).
withdrawal_credentials32-byte withdrawal credentials from the deposit (hex).
withdrawal_prefixCredential type prefix (for example 0x01 for execution / address withdrawals).
withdrawal_addressExecution-layer withdrawal address when applicable (hex).
slashedWhether the validator has been slashed.
activation_eligibility_epochEpoch when the validator became eligible for activation.
activation_epochEpoch when the validator was activated.
exit_epochEpoch when the validator exited or will exit (18446744073709551615 means “not set” / far future in consensus encoding).
withdrawable_epochEpoch when balance becomes withdrawable (same sentinel applies when not applicable).
execution_optimisticExecution optimistic flag when present; may be empty depending on upstream payload metadata.
finalizedWhether the beacon data for this row is finalized.
unique_idStable row id, for example date-2026-03-28-validator_index-2067035.
_created_atWhen this row was written in Allium.
_updated_atWhen this row was last updated in Allium.

Sample Queries

​
Query 1: Daily network-wide staking metrics (UTC days)

select
    date(slot_timestamp) as snapshot_day,
    count(*) as total_validators,
    sum(balance) as total_balance_eth,
    sum(effective_balance) as total_effective_balance_eth,
    avg(balance) as avg_balance_per_validator,
    countif(status = 'active_ongoing') as active_validators
from beacon.raw.balances_daily
group by snapshot_day
order by snapshot_day desc
limit 30

​
Query 2: Individual validator balance history

select
    date(slot_timestamp) as snapshot_day,
    balance,
    effective_balance,
    status,
    balance - lag(balance) over (partition by validator_index order by slot_timestamp) as daily_balance_change_eth
from beacon.raw.balances_daily
where validator_index = 12345
order by snapshot_day desc
limit 90

​
Query 3: Rows where validators are slashed
