Project Capybara is now live on X1 Blockchain — a delegation reward upgrade announced by @MrJackLevin (also @jacklevinj on Telegram) that changes how Foundation delegation rewards are distributed among validators. Named after the famously calm and long-lived rodent that thrives in harsh environments, Project Capybara rewards operators who commit real skin in the game, not those who run minimum-stake bot farms on cheap VPS nodes.
The Problem Capybara Solves
Before Capybara, the barrier to entry for X1 Foundation Delegation was effectively nonexistent. Validators needed just 2 XNT of self-stake to qualify for Foundation delegation — a sum so small it could be covered by a few minutes of block rewards. The result was predictable: a proliferation of low-effort validator nodes running on $20-per-month VPS instances, staking the bare minimum, and collecting substantial Foundation delegation rewards without contributing meaningfully to network health, stability, or decentralization.
The old system created a perverse incentive structure. It rewarded extraction over contribution. Operators who invested in proper infrastructure, maintained high uptime, and staked meaningful amounts of their own capital received the same delegation weight as those who spun up a minimal node and walked away. The Foundation delegation program, designed to bootstrap network security, had become a subsidy for validator farms rather than a reward for genuine commitment.
Project Capybara changes that.
The P85 Mechanic: How the Threshold Works
Operators can check their current percentile, self-stake, and delegation status using the VALIDATOR TERMINAL.
At the heart of Capybara is the P85 threshold — a percentile-based minimum that ensures only validators with above-average commitment receive Foundation delegation.
P85 = the 85th percentile of all validators' self-stake amounts.
This means that in any given epoch, the threshold is set such that the top 15% of validators by self-stake qualify for full Foundation delegation. Validators below this line receive nothing. The threshold is recalculated each epoch as the stake distribution changes, ensuring the system remains dynamically fair.
Here is how the threshold has evolved:
- Pre-Capybara: 2 XNT minimum — effectively no barrier. Anyone could qualify.
- Phase 1 (~April 2026): Raised to 1,000 XNT, which at the time represented approximately the 85th percentile. This was roughly the 15th percentile of validators when initially set, but as operators increased stakes to qualify, the distribution shifted.
- Phase 2 (June 24, 2026): Raised to 3,000 XNT — the new P85 after validators adapted to the 1,000 XNT floor and the competitive landscape tightened.
The key insight is that P85 is not static. It is a living threshold that responds to validator behavior. When operators increase self-stake to qualify, the percentile shifts upward, raising the bar for everyone. This creates a natural race-to-the-top dynamic where validators compete on commitment rather than extracting minimum viable rewards.
In practice, the threshold's relationship to the literal 85th percentile has already started to drift. As of this writing, self-stake percentiles among the network's 716 non-X1 validators put the median (P50) at 2,991.71 XNT and P75 at 3,108.32 XNT — meaning roughly half of all non-X1 validators already clear the 3,000 XNT floor, not just the top 15% the P85 label implies. The actual current P85 sits higher still, at 3,980.05 XNT, just above Ripper Pool's dynamic floor. The distribution has kept climbing past the announced number, so 3,000 XNT today functions more like a fixed minimum bar than a percentile recalculated in lockstep every epoch.
A New Dimension in the Formula
Capybara does not merely raise the floor. It introduces a new design dimension to the delegation reward formula. Important caveat: The exact mathematical implementation has not been published. What follows describes the design intent as announced by @MrJackLevin and confirmed by @jacklevinj on Telegram.
Self-Stake Against Network Average
Validators are expected to receive delegation weight proportional to how far above the network average their self-stake sits. As of this writing, mean self-stake among non-X1 validators is 2,483.77 XNT (median 2,991.71 XNT) — meaning the 3,000 XNT Foundation floor already sits above the network average. This means delegation is no longer a binary qualify-or-don't-qualify proposition. Instead, it is a graduated scale where operators who stake 5,000 XNT earn more weight than those at 3,000 XNT, who in turn earn more than those barely clearing the threshold. The design intent is to explicitly reward operators who go beyond the minimum.
What is confirmed vs inferred:
- ✅ Confirmed: Minimum self-stake floor raised to 3,000 XNT (live, effective next few epochs)
- ✅ Confirmed: A new formula dimension weighting self-stake against the network average is being added
- ⚠️ Inferred: Exact weighting formulas and calculation methods have not been published
- ⚠️ Inferred: Specific numerical impacts on individual validators depend on final implementation
Given this dimension, the ideal validator under Capybara is one that:
- Stakes significantly above the network average (not just above the minimum)
- Maintains high uptime and performance (since delinquent validators lose vote credits)
Impact on Validators: Winners, Losers, and the Margin
The validator landscape under Capybara divides into three clear camps.
Clear Winners: Validators already staking above 3,000 XNT — and especially those above the network average — now qualify for Foundation delegation. They were already committed operators; Capybara simply ensures their commitment is recognized and rewarded proportionally. For validators in the 5,000–10,000 XNT self-stake range, their above-average self-stake weight alone should meaningfully increase total returns under the new formula.
The Margin: Validators sitting between 3,000 XNT and the network average face a decision. They qualify for Foundation delegation, but if the graduated weighting is implemented as described, their weight will be minimal. To maximize returns, they must either increase self-stake above the average or accept lower-than-optimal delegation weight. This is intentional — it forces operators to make an explicit economic choice about their commitment level.
Clear Losers: Cheap VPS nodes running on minimal self-stake are being systematically kicked out of the program. The $20-per-month instances that contributed nothing to network health beyond consuming delegation rewards are no longer economically viable. Their operators must either upgrade infrastructure, increase self-stake, or exit. Either way, the network becomes healthier.
From a game-theory perspective, Capybara creates a virtuous cycle:
- Higher self-stake requirements lock more XNT out of circulation
- Reduced liquid supply creates deflationary pressure on XNT
- Higher XNT prices make staking more attractive
- More staking increases network security and decentralization
- A more secure network attracts more users and applications
- Growing utility further supports XNT price
Impact on Ripper Pool: The Double Filter
While the X1 Foundation Delegation Program now requires 3,000 XNT minimum self-stake, X1 Ripper Pool — the liquid staking protocol built in partnership with BlackPearl and supported by X1 Labs — maintains its own dynamic validator selection criteria that operate independently of Foundation thresholds.
Ripper Pool's MIN SELF STAKE was set at 3,976.68 XNT at time of writing — nearly a thousand XNT higher than the Foundation's new floor. Note: This figure is dynamic and adjusts based on network conditions and validator performance.
This creates a powerful "double filter" in the X1 validator ecosystem:
- 3,000 XNT: Qualifies for Foundation delegation. Roughly half of non-X1 validators now clear this bar, per current self-stake percentiles — well above the 15% a strict P85 read would imply.
- ~3,977 XNT (dynamic): Qualifies for Ripper Pool delegation. A smaller subset of the most committed operators.
Validators staking between 3,000 and ~3,977 XNT qualify for Foundation delegation but not for Ripper Pool. They receive Foundation rewards and commissions from their own stake, but they miss out on the additional delegated stake from the liquid staking protocol.
Validators staking above ~3,977 XNT qualify for both programs. They receive:
- Foundation delegation weight (scaled by self-stake vs. network average)
- Ripper Pool liquid staking delegation (dynamic, protocol-level delegation)
- Higher total delegated stake, which generates more commission revenue
- Greater network visibility and reputation, since they appear in both programs
This dual-threshold system is intentional. The Foundation's 3,000 XNT bar is designed to kick out low-commitment operators and bootstrap a baseline of healthy validators. Ripper Pool's 3,976.68 XNT bar is designed to identify the elite subset of those validators — the ones with the most skin in the game — and concentrate liquid staking capital on them.
Because Ripper Pool's MIN SELF STAKE is dynamic — it adjusts based on network conditions and validator performance — it acts as a real-time quality filter that continuously optimizes delegation toward the best-performing operators. The 3,976.68 XNT figure was current at time of writing and may have adjusted since.
The Bigger Picture for X1
Project Capybara is more than a validator policy update. It is a signal about how X1 Blockchain intends to grow its proof-of-stake economy.
By raising the cost of participation, Capybara ensures that validator rewards flow to operators who have real capital at risk. This aligns incentives: validators who stand to lose significant value if the network underperforms are the same validators who have the strongest motivation to maintain excellent uptime, fast block production, and honest consensus participation.
Combined with the deflationary effect of locked XNT (94.5% of supply is already staked, and Capybara pushes more liquid XNT into self-stake), these changes create a structural support for XNT price and network security that extends far beyond the validator layer.
Why "Capybara"?
The name is intentional. Capybaras are known for being calm under pressure, long-lived, and adaptable to harsh environments. They thrive in conditions that would stress lesser species. The metaphor maps cleanly onto the ideal X1 validator: an operator who stakes meaningful capital, maintains consistent performance through market volatility, and remains committed to the network's long-term health regardless of short-term price action.
In a space dominated by mercenary capital and rotating validator farms, X1 is betting on the capybaras.
What Comes Next
The 3,000 XNT threshold is effective immediately and will be applied starting in the next few epochs. Validators who have not yet reached this level will see their Foundation delegation removed. Those above the threshold will see their rewards adjusted according to the new graduated formula.
For operators considering whether to increase self-stake, the direction is clear: every additional XNT staked above the network average increases potential delegation weight. The operators who move fastest will capture the highest rewards before the rest of the field catches up.
For the X1 ecosystem as a whole, Capybara represents a maturation milestone. The network is no longer in bootstrap mode, where any participation is welcome. It is transitioning into a phase where quality, commitment, and longevity are the criteria for success. And that is exactly what a proof-of-stake network needs to thrive.
