Blockchain security is not just a matter of technology, but also of user trust. The Ethereum Security Initiative aims to significantly improve the security of the Ethereum ecosystem. This includes funding audits of smart contracts, creating open tools for developers, and supporting security researchers. In an era where hacks of DeFi platforms lead to millions in losses, enhanced security is not a luxury, but a necessity. The community must come together to make Ethereum not only scalable but also a secure environment for all users, from developers to investors.
