Deep Dive
1. Public Burn Function (25 July 2025)
Overview: Added an open on-chain function allowing validators to burn MPX tokens, directly reducing supply.
This update capped validator MPX holdings at 10% and automated burns equivalent to staking rewards. For example, when users staked 1M XFI during the Native-Staking Sprint, the system burned 4M MPX. Over 1.46B MPX was permanently destroyed, shifting 70% of MPX supply to community validators.
What this means: This is bullish for XFI because it reduces inflationary pressure while decentralizing network control. Users benefit from fairer governance and reduced risk of validator monopolies.

2. Native-Staking Module (10 July 2025)
Overview: A new smart contract module linked XFI staking to MPX bonuses, with automatic burns to neutralize inflation.
The code matched user-staked XFI 1:4 with MPX rewards, then immediately burned the rewarded MPX. This mechanism distributed 1.46B MPX to top validators while burning an equal amount, tripling the decentralization index.
What this means: This is neutral for short-term price (balances rewards with burns) but bullish long-term by incentivizing participation and reducing centralization risks.

3. XFI Scan Explorer (6 August 2025)
Overview: Launched an EVM-compatible blockchain explorer for real-time tracking of wallets, validators, and transactions.
The tool integrates with MetaMask and CrossFi’s xApp, providing non-custodial users with granular data like staking rewards, validator uptime, and token circulation. It uses Cosmos SDK modules for cross-chain compatibility.
What this means: This is bullish for XFI because transparency builds trust in self-custody systems, potentially attracting more DeFi users.

Conclusion
CrossFi’s codebase shifts toward community-driven mechanics, using burns and staking modules to combat inflation while prioritizing transparency via XFI Scan. How will these updates impact validator participation rates as the 10% MPX cap gets stress-tested?
