On May 2025, the Ethereum Foundation announced the launch of the "Trillion Dollar Security" (1TS) program, aimed at enhancing network security to a level that can support global-scale financial applications, with the goal of providing security for billions of users and assets at the trillion-dollar level. The core of this program is to build an underlying framework capable of withstanding large-scale attacks through systematic improvements across various aspects of the Ethereum ecosystem, including smart contracts, infrastructure, consensus protocols, and user experience.

A comprehensive scan of potential vulnerabilities in the Ethereum tech stack, covering wallet security, node connectivity, and other aspects, to identify systemic risks.

High-priority fixes for critical issues (such as blind signatures and consensus layer threats) while promoting long-term infrastructure optimizations, such as improving the staking mechanism (e.g., EIP-7251 will raise the validator staking cap from 32 ETH to 2048 ETH) and block building processes (e.g., EIP-6110).

Enhancing ecosystem transparency and trust through regular progress reports and open community participation, attracting developers, institutions, and governments to collaborate.

This program is a response to multiple security incidents in Ethereum's history (such as The DAO attack and Parity wallet vulnerabilities), aiming to address legacy risks in areas like DeFi and cross-chain bridges, and to pave the way for institutional-level applications. The leadership team is headed by Fredrik Svantes, the Ethereum Foundation's Protocol Security Lead, and core member Josh Stark, in collaboration with top security experts from institutions like Paradigm and Sigma Prime, highlighting its technical authority. Moreover, with the advancement of the Pectra upgrade (such as the account abstraction feature EIP-3074), Ethereum further strengthens the network's scalability and security, laying the foundation for its goal of becoming the "global financial infrastructure."

This program is not only a milestone in the evolution of Ethereum technology but also marks its strategic determination to transition from an "experimental network" to a "civilization-level infrastructure."
