Definition. This chart shows the aggregate balance of the Ethereum Proof-of-Stake validator set from three angles: the Total Value Staked 🟢 (green columns) — the sum of all active validator balances — the aggregate Effective Balance (red line), and the Stake Effectiveness ratio 🟣 (purple), alongside price (grey).

Technical. Validators must initially deposit a stake of 32 ETH to start a validator, and will be ejected from the protocol if their balance falls below 16 ETH (in the event of inactivity leak or slashing). Once a validator is active, their total ETH balance will begin to change due to a number of factors:

• Revenue earned from issuance and fees (balance increase)
• Inactivity leak if validators often miss blocks or attestations (balance decreases)
• Slashing in the event of malicious behavior (balance decreases)

The Total Value Staked reflects the sum of all staked deposits, revenue earned, and subtracted penalties from inactivity leak and slashing. Each validator also has an Effective Balance, which is capped at 32 ETH on the upside (raised to up to 2,048 ETH for consolidated validators by the Pectra upgrade), and decreases to the nearest 1 ETH increment below this (with a minimum buffer of 0.25 ETH). For example:

• If a staker has 32 ETH and earns 0.5 ETH in rewards, their Total Balance is 32.5 ETH, but their Effective Balance is still 32 ETH.
• If a staker has 32 ETH but leaks 0.5 ETH in inactivity penalty, their Total Balance is now 31.5 ETH, but their Effective Balance is rounded down to 31 ETH.
• A Total Balance of 31.250 ETH will have an Effective Balance of 31 ETH.
• A Total Balance of 31.249 ETH will have an Effective Balance of 30 ETH.

Stake Effectiveness 🟣 is then calculated as the ratio between Effective and Total staked ETH; the green Total Value Staked columns are derived from the two native series as Effective Balance / Stake Effectiveness, recovering the aggregate balance of the active validator set.

Interpretation. Total Value Staked tracks the economic weight committed to securing Ethereum consensus, and its growth reflects net staking demand. Effective Balance is the portion that actually counts toward consensus and rewards, so the gap between the two — summarized by Stake Effectiveness — measures how efficiently the validator set converts stake into consensus weight. A Stake Effectiveness persistently near 1.0 describes a healthy, well-maintained validator population, while deterioration points to accumulating rewards sitting above the effective-balance cap or balance erosion from inactivity and slashing.
