Slashing, Validator Accountability & Risk Management under hATOM
In the hATOM model, slashing still applies strictly to the native ATOM staked on validators, not to hATOM itself. Users receive hATOM as a liquid representation of staked ATOM, but only the underlying ATOM is exposed to slashing risk. If a validator commits a slashable offense, the pool of staked ATOM is reduced accordingly, and this impact is reflected through a small decrease in the hATOM exchange rate. No hATOM is ever burned or removed from user wallets; instead, the backing value per hATOM adjusts, just as with established LSTs such as stETH.
Because hATOM consolidates all staked ATOM into a unified pool, slashing risk becomes partially socialized across all hATOM holders. This is a natural property of any pooled liquid staking model. To prevent validator complacency and to maintain a high-quality validator set, the Cosmos Hub’s governance can introduce several mechanisms that reinforce accountability and decentralisation.
-
governance can establish curated validator-set criteria ( delegation program could help + set reduction ) defining the minimum standards for inclusion in the hATOM staking set, such as minimum uptime, maximum commission, and historical performance requirements. Validators failing to meet these standards can be excluded or deprioritized.
-
the Hub can implement a dynamic delegation allocation system, where validators who exhibit poor performance, high downtime, or increased slashing risk automatically receive reduced delegation from the hATOM pool. Conversely, top-performing validators can be proportionally favored. This preserves competition and discourages complacency. Compatibility with the Nakamoto Coefficient Bonus
This feature remains fully compatible with the “Nakamoto Bonus” system that I proposed for improving validator decentralization ( [SIGNALING PROPOSAL] [DRAFT] Improve the Nakamoto Coefficient ). Both mechanisms operate on different layers of the protocol and can coexist without interfering with each other, as long as their responsibilities are kept separate.
The dynamic delegation allocation system optimizes for validator performance and network safety. It automatically adjusts the distribution of hATOM-backed stake toward high-quality validators and away from those presenting excessive slashing risk or poor uptime.
The Nakamoto Bonus, by contrast, is concerned with decentralization rather than performance. It modifies validator rewards, not delegation, by granting increased income to validators who contribute to a higher Nakamoto coefficient (less power concentration), and reducing rewards for those who increase stake centralization.
Because the two systems operate on two different axes, performance vs decentralization, they do not compete or create instability when combined. Dynamic delegation maintains network reliability, while the Nakamoto Bonus provides economic incentives to strengthen decentralization. Together, they form a complementary mechanism that improves validator set quality and validator distribution at the same time.
I think these measures ensure that even though hATOM creates a consolidated staking system, validators remain accountable, decentralisation is preserved, and users maintain meaningful influence over validator selection. With transparent dashboards, performance reporting, and on-chain risk signals, the Hub can operate a highly secure, responsibly curated validator set that aligns with the needs of both the network and the long-term hATOM holders.
