The initiative #EthereumSecurityInitiative strengthens the security of Ethereum through collaborative audits and standards. It highlights the Attackathon, an event organized by the Ethereum Foundation and Immunefi, with a reward pool of $1.5 million, inviting researchers to identify vulnerabilities in the protocol. In parallel, the ETH Rangers program offers stipends of $25,000 to those who contribute to the security of the ecosystem. Additionally, the Enterprise Ethereum Alliance promotes EthTrust, a certification system for audited smart contracts, increasing trust in decentralized transactions. These actions consolidate Ethereum as a secure and reliable platform.
