The Ethereum Foundation recently published a blog outlining three protocol cluster priorities: scaling, UX, and hardness.
Each addresses a different requirement for Ethereum’s long-term success. Scaling ensures the network can support global demand. UX ensures people can actually use it. Hardness ensures that, as Ethereum grows, it retains the properties that make it worth using in the first place.
Here is a deeper look at the Hardness focus and what it means for the Ethereum ecosystem.
What Hardness Is
Hardness is the quality of a system to be reliable in the future, and the hardness track is a protocol-level commitment to preserving Ethereum’s core guarantees: open source, censorship resistance, privacy, security, permissionlessness, and trust minimization.
Hardness has always mattered. These principles have been part of Ethereum since the beginning.
Ethereum exists to provide neutral infrastructure for the people who actually need it, even when that choice is harder, slower, or less convenient. In practice, that means ensuring Ethereum works even when centralized systems fail.
A user in a sanctioned country. A journalist protecting sources. An organization needing neutral settlement infrastructure. An institution minimizing counterparty risk.
Why Focus on Hardness Now
Ethereum is shipping major improvements to throughput and usability. Each of these improvements could be achieved by taking shortcuts, like centralizing infrastructure or introducing trusted intermediaries.
Hardness exists to ensure Ethereum stays true to its values while also responding to the needs of the network.
Today, people and institutions rely on Ethereum’s guarantees not as ideals, but as necessities which makes hardness an increasingly critical area of focus.
What Hardness Looks Like in Practice
At the Ethereum Foundation, hardness focus areas will be stewarded by Thomas Thiery, Parithosh Jayanthi, and Fredrik Svantes, each bringing a different area of emphasis:
Thomas Thiery on censorship resistance and permissionlessness at the protocol levelFredrik Svantes on security, with focus on privacy and trust minimizationParithosh Jayanthi on infrastructure, upgrades and resilience of the sensitive parts of the Ethereum protocol depends on remain secure and resilient
Hardness spans several areas:
In addition to this technical R&D, part of the hardness track is helping others understand and prioritize these core properties. The team will also work alongside ZK, privacy, scaling, UX, and security efforts like
Trillion Dollar Security,
which focus more heavily on wallets and the application layer, to ensure hardness is represented so that these improvements accelerate progress without weakening security or decentralization.
Network resilience - Improving tooling, testing, and fuzzing to surface vulnerabilities early, and ensuring the network can recover quickly if failures occur.User protection - Reducing preventable fund loss from phishing and drainers.Privacy - Working toward private transfers and anonymous broadcast at the protocol level, giving users strong confidentiality guarantees without leaving L1.Preserving neutrality - Designing against single points of failure at the edge of the network to ensure it remains neutral and resilient against selective interference.Long-term preparedness - Post-quantum cryptography isn’t an immediate threat, but it is an inevitable threat we must prepare for.Fallback and recovery modes - As throughput increases, the protocol must be able to slow down and stabilize when anomalies occur, allowing the network to heal rather than cascade.Incident readiness - Developing shared, public runbooks so the ecosystem can respond quickly and transparently in extreme scenarios.Measuring reality - Establishing metrics to understand: how censorship-resistant the ecosystem is today, how many users can transact privately, where trust assumptions are creeping in & more.

The success of the hardness focus relies on ecosystem feedback.
