• Trillion Dollar Security Day at Devconnect Posted by Ethereum Foundation Team on February 3, 2026 Security During Devconnect Buenos Aires, the Ethereum Foundation andSecureumTrustX brought together Ethereum security practitioners for Trillion Dollar Security Day, a focused event exploring what it would take to securely support a trillion-dollar Ethereum economy. • The event brought together around eighty participants from across the Ethereum Security Ecosystem-spanning Infrastructure, Interoperability, Layer 1 & 2, Onchain, Offchain, Privacy, and Wallets-to assess the current security landscape, surface shared challenges, and identify concrete next steps across the stack. • The discussions and outputs from this event contribute to the Ethereum Foundation’s ongoing One Trillion Dollar Security (1TS) initiative. • Why a Trillion Dollar Security Day? • The Trillion Dollar Security day was designed to create focused, in-person discussions within individual layers, bringing together practitioners who work on similar parts of the stack to assess current security posture, share operational realities, and identify near-term priorities. • The outcomes of these sessions were then synthesized to highlight patterns and dependencies across the broader ecosystem.

Article Summaries:

  • During Devconnect Buenos Aires, the Ethereum Foundation and Secureum TrustX convened a “Trillion Dollar Security Day” with about 80 security practitioners from across the Ethereum ecosystem. The event aimed to assess the current security posture of a projected trillion‑dollar Ethereum economy, identify gaps, and set actionable priorities. Participants highlighted recurring issues such as treating security as a milestone, unclear trust assumptions, insufficient funding for public‑goods tooling, and coordination bottlenecks between Layer 1 and Layer 2. Key next steps include expanding the Ethereum Protocol Fellowship, creating clearer L2 liaison roles, improving EIP versioning, and enhancing moderation in coordination forums to strengthen long‑term security.
