Vitalik: The Ethereum Foundation is entering a mild tightening period, and individuals will invest 16000 ETH to promote an open source verifiable full stack ecosystem Ethereum founder Vitalik Buterin stated in an article on the X platform that in the past five years, the Ethereum Foundation is entering a mild tightening period, aiming to achieve two major goals simultaneously: first, to deliver a positive roadmap to ensure that Ethereum becomes a high-performance, scalable, robust, sustainable, and decentralized world computer; The second is to ensure the long-term sustainable development capability of the foundation itself and uphold the core mission of Ethereum, including the core blockchain layer and the ability of users to access and use the chain under the premise of self sovereignty, security, and privacy. Therefore, Vitalik himself will personally undertake some of the responsibilities that may have belonged to the foundation's "special program". The focus is on promoting the construction of an open source, secure, and verifiable software and hardware full stack system to protect the security and privacy of individuals and public environments, covering multiple fields such as finance, communication, governance, blockchain, operating systems, security hardware, and biotechnology. Therefore, it has just withdrawn 16384 ETH, which will be used in the coming years to advance these goals and explore secure decentralized staking schemes, with the aim of investing more staking profits into these goals in the long term. Vitalik emphasized that Ethereum itself is an indispensable part of realizing the vision of "full stack openness and verifiability". The foundation will continue to firmly focus on the development of Ethereum, with a core priority direction of serving those who truly need it - providing self sovereign infrastructure, rather than simply pursuing commercial expansion. In today's environment that advocates power competition, building a truly open, secure, and verifiable technological foundation is an important way to ensure individual and community autonomy and security.
