🏝️Solana SRB

SOL Staking Rewards Benchmark (SOLSRB™) Methodology

SOLSRB is a benchmark representing the mean, annualized staking rate across all active Solana validators.

SOLSRB is calculated and published by Staking Rewards via the Solana Profile and Staking Data API.

SOLSRB=irest/stAvg30d/(ss/ts)SOLSRB = ir * est / stAvg30d / (ss / ts)
Formula key
Metric name
Description

ir

Inflation Rate

The annual rate at which supply increase. It was initiated at a rate of 8% in February 2021 and is expected to decline by 15% annually until reaching a steady state of 1.5%.

est

Expected Slot Time

The theoretical time proposed by the consensus.

stAvg30d

30 Day Average of Slot Time

Average real slot time over the last 30 days.

ss

Staked Supply

Number of Self-Staked and Delegated tokens to Solana Validators.

ts

Total Supply

All Solana tokens minted minus all Solana tokens burnt.

Slashing

  1. SOLSRB does not factor in the possibility of slashing occurrences.

  2. There is no token slashing implemented at this stage.


SOL Validator Staking Reward Rate: SOLSRB(v)

Staking Rewards calculates the SOLSRB for each validator based on their individual performance and commission rate.

SOLSRB(v)=(vrpe/vss)epy(1c)SOLSRB(v) = (vrpe / vss) * epy * (1 - c)
Formula key
Metric name
Description

vrpe

Validator Rewards per Epoch

Based on the validator performance history, it is possible to determine it's rewards for the epoch.

vss

Validator Staked Tokens

The sum of Self-staked tokens and the Delegated tokens for a specific validator.

epy

Epochs per Year

Based on the slot and epoch times, we derive the number of estimated epochs in a year.

c

Commission

The fee imposed by a specifici validator to it's delegators


Observation Period:

  1. The SOLSRB is determined based on the latest generated block at the point of evaluation.

  2. 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

  1. SOLSRB excludes rewards accrued from onchain fees.

  2. SOLSRB employs a 365-day convention for annualizing current slot times. This convention remains consistent and does not accommodate adjustments for leap years.

SOL Real Reward Rate: SOLSRB^R

The real reward rate calculates the SOLSRB adjusted for inflation in the network.

SOLSRBR=1+SOLSRB/(1+ir)1SOLSRB^R=1 + SOLSRB/(1+ir) -1
Formula key
Metric name
Description

ir

Inflation Rate

The annual rate at which supply increase. It was initiated at a rate of 8% in February 2021 and is expected to decline by 15% annually until reaching a steady state of 1.5%.


Other Solana metrics calculated by Staking Rewards:

Metric
Description

Delegated Tokens

The number of SOL tokens delegated to validators.

Self Staked Tokens

The number of SOL tokens staked by validators directly.

Staking Wallets

Total number of unique delegations onchain. It doesn't distinguish based on unique delegator addresses.
