🔬Cardano SRB
ADA Staking Rewards Benchmark (ADASRB™) Methodology
ADASRB is a benchmark representing the mean, annualized staking rate across all active Cardano validators.
ADASRB is calculated and published by Staking Rewards via the Cardano Profile and Staking Data API.
Formula key | Metric name | Description |
---|---|---|
er | Epoch Rewards | The rewards to be distributed among all staking pools within the protocol. Each epoch lasts 5 days. |
ast | Active Staked Tokens | The sum of all staked tokens that are eligible for reward distribution. There is a 2-epoch delay period where new tokens do not qualify for distribution. |
Slashing
Cardano does not have a slashing mechanism.
ADA Validator Staking Reward Rate: SOLSRB(v)
Staking Rewards calculates the ADASRB for each validator based on their individual performance, commission rate, and luck factor.
Formula key | Metric name | Description |
---|---|---|
pr | Pool Rewards | The rewards attributed to a specific pool given its uptime, staked tokens, and luck factor. |
pst | Pool Staked Tokens | The sum of Self-staked tokens and the Delegated tokens for a specific pool. |
c | Commission | The fee imposed by a specific validator to its delegators. |
Observation Period:
The ADASRB is determined based on the latest generated block at the point of evaluation.
This data is then annualized for a comprehensive year-long projection.
Calculation
The calculation happens every 2 hours and is immediately published via Staking Data API.
Limitations
SOLSRB employs a 365-day convention for annualizing current slot times. This convention remains consistent and does not accommodate adjustments for leap years.
ADA Real Reward Rate: ADASRB^R
The real reward rate calculates the ADASRB adjusted for inflation in the network.
Formula key | Metric name | Description |
---|---|---|
ir | Inflation Rate | The annual rate at which supply increase. The Cardano inflation rate is approximately 7% per year, leading up to a maximum supply of 45 billion ADA. However, it varies depending on factors such as staking rewards, and the total amount of ADA staked in the network. |
Other Cardano metrics calculated by Staking Rewards:
Metric | Description |
---|---|
Delegated Tokens | The number of ADA tokens delegated to validators. |
Self Staked Tokens | The number of ADA tokens staked by validators directly. |
Staking Wallets | Total number of unique delegations on-chain. It doesn't distinguish based on unique delegator addresses. |
