🔲Aleo SRB
ALEO Staking Rewards Benchmark (ALEOSRB™) Methodology
AleoSRB is a benchmark representing the mean, annualized staking rate across all active Aleo validators.
AleoSRB is calculated and published by Staking Rewards via the Aleo Profile and Data API.
br
Base Block Reward
The fixed base reward per block distributed to validators (4.756468 ALEO credits per block)
bpy
Blocks Per Year
Estimated annual block count, derived from observed average block time over a 1000-block window: 365 × 86400 / avg_block_time
ts
Total Staked
The total amount of ALEO credits staked across all active validators in the committee
Non-compounded: AleoSRB excludes returns from reinvestment of rewards, presenting the base annualized rate.
Base Reward Only: The SRB uses the fixed base block reward (4,756,468 microcredits) and excludes variable transaction fee rewards, which fluctuate per block and are not a guaranteed staking return.
All Rewards Counted: Includes both claimed and unclaimed staking rewards across all active validators.
ALEO Rewards Distribution
Aleo uses the AleoBFT consensus mechanism, a committee-based Proof-of-Stake system where validators are selected to participate in block production based on their stake weight.
Here's how the process works:
Committee Selection: Validators with sufficient stake (minimum 10,000 ALEO credits bonded) are eligible for the active committee. The committee is determined by stake weight, with the top staked validators forming the active set.
Block Production: Committee members take turns proposing and attesting to blocks. Each block carries a fixed base reward of 4,756,468 microcredits (~4.756 ALEO) plus variable transaction fees.
Reward Distribution: Block rewards are distributed to the block producer. Validators earn rewards proportional to their participation in the committee. Validators charge a commission (0–100%) on delegator rewards.
Delegation: Token holders can delegate their ALEO credits to any validator that accepts delegations (
is_open = true). Delegators earn the asset reward rate adjusted by their chosen validator's commission rate.
Validator-Level SRB: AleoSRB(v)
c
Commission
The validator's commission rate (0–100%), representing the percentage of delegator rewards retained by the validator
Observation Period
Determined based on the latest generated block at the point of evaluation. Block time is measured over a 1000-block window for statistical accuracy.
Annualized for a comprehensive year-long projection using a 365-day convention.
Calculation Frequency
The calculation happens every 6 hours and is immediately published via Data API.
Aleo Real Reward Rate (ALEOSRB^R)
The real reward rate calculates the AleoSRB adjusted for inflation in the network.
i
Inflation Rate
The annual inflation rate of the ALEO token supply, calculated as: (base_block_reward × blocks_per_year) / total_supply
Inflation Rate Behaviour
Aleo's inflation rate is dynamically calculated based on the fixed base block reward and the current total supply. As the total supply grows over time through block rewards, the inflation rate naturally decreases. The current observed inflation rate is approximately 2.4%. Since the base block reward is fixed, inflation will continue to decline asymptotically as total supply increases.
Aleo's Validator Framework: A Slashing-Free Environment
In Aleo, validators are not penalized with slashing for mistakes or misbehavior, which means stakers do not risk losing their funds due to validator errors. This design aims to make staking safer for participants. However, while there are no slashing penalties, validators can still experience issues such as downtime, which may affect their ability to earn rewards. Overall, the absence of slashing encourages participation without the fear of significant financial loss due to validator misconduct.

Delegated Tokens
The number of ALEO tokens delegated to validators by external delegators.
Self Staked Tokens
The number of ALEO tokens bonded by validators directly from their own balance.
