The Ethereum Foundation recently announced the launch of the 'Trillion Dollar Security Initiative' (1TS), aimed at comprehensively enhancing the security of the Ethereum ecosystem, with the goal of creating 'civilization-level infrastructure' that supports the global economy and the internet. The initiative is divided into three parts: first, mapping the security landscape of the Ethereum technology stack, assessing the security strengths and risks in areas such as user experience, wallets, contracts, and infrastructure; secondly, focusing on priority security issues through targeted efforts by funding research, development, auditing, and formal verification to enhance protocol security; finally, reshaping users' perception of mainnet security through community education and transparent communication. The initiative is led by Ethereum security experts in collaboration with ecosystem leaders, and global developers can participate through ESP funding. Discussions on platform X show that the community has responded positively to this initiative, believing it will enhance user and institutional trust in Ethereum, but also emphasizing the need to pay attention to implementation effects and potential costs. In the future, 1TS is expected to drive Ethereum to become a more secure and trustworthy blockchain platform.
