Proposal: Restore XPRT Inflation to Strengthen Staking & Security
Summary
The recent reduction in XPRT’s inflation at Block 21,038,400 (March 12, 2025) has dropped staking rewards to historically low levels. While lower inflation has certain benefits, in the current climate and with the current state of affairs (pre-mainnet for the new product and for Babylon staking security), it may discourage staking, weaken network security, and impact validator revenues.
I propose raising inflation back to 6.25% min and 12.5% max—the levels before the latest halving. This will restore staking incentives, support validators, and maintain strong network security, ensuring Persistence remains attractive for stakers and validators while we continue building real utility for XPRT.
How We Got Here: A Quick History
XPRT’s inflation parameters have changed multiple times through governance and pre-programmed halvings. Initially, inflation ranged from 25% to 45% at genesis. In May 2023 (Prop 23), inflation was reduced early to 12.5%–25% to align with block time adjustments. In June 2024 (Prop 109), inflation was halved again to 6.25%–12.5% as part of a broader effort to slow down supply growth. Finally, as scheduled, on March 12, 2025 (Block 21,038,400), inflation was automatically reduced again to 3.125%–6.25%.
While these reductions were made with good intentions—to curb inflationary pressure and align with Cosmos-wide trends—the effects on staking participation and validator economics now need to be reassessed.
Why This Change is Needed
- Staking Rewards Have Declined Too Much – With lower inflation, staking APR has dropped significantly (~9.8% at 6.25% inflation vs. much lower at current levels). Lower rewards reduce incentives for long-term staking, which could weaken network security over time.
- Validator Revenues Are Reduced– Lower inflation means lower staking rewards, leading to reduced commission income for validators. This could make it harder for smaller validators to remain profitable, potentially harming decentralization.
- Security Should Remain a Priority – Until external security solutions like Babylon BTC finality are fully integrated, we should ensure that staking remains a strong security mechanism.
Proposed Solution
- Increase minimum inflation to 6.25% (from 3.125%) and maximum inflation to 12.5% (from ~6.25%).
- This restores the inflation range from before the latest halving, ensuring staking remains competitive and validators are properly incentivized.
- At 6.25% inflation, staking APR would be back around ~20%, making XPRT staking more attractive while keeping inflation manageable.
Why This Makes Sense Now
- Stronger staking incentives = higher participation and better network security.
- Better validator economics = reduced risk of validator centralization or attrition.
- A more engaged and secure network ensures Persistence can continue to grow while adoption efforts take shape.
- This doesn’t mean inflation stays high forever—we can revisit reductions once staking is more sustainable and XPRT’s utility is further developed.
Let’s Discuss!
This proposal finds the right balance: restoring security and incentives while keeping inflation reasonable. We need a strong foundation before moving to a lower-inflation model.
